Description of the types of instrument panels MTZ 82(80)

Over the course of more than forty years of production, the Belarus tractor has undergone a number of changes in the cabin interior due to the modernization of the machine and the improvement of the control system for the operation of mechanisms and components, as well as due to the improvement of the ergonomic qualities of the driver’s workplace.
Speaking about equipping the MTZ 80(82) with control and measuring sensors, it should be noted that the tractor, depending on the year of manufacture, is equipped with three versions of instrument panels, which are an integral part of the control system. Instrument panel MTZ 80.1

MTZ instrument panel - design and repair

MTZ instrument panels are mounted on tractors with a large or small cab. Usually they are equipped with blocks of warning lamps or fuses.

The instrument panel housing protects the equipment from moisture, dust, and mechanical influences.

Thus, electrical circuits operate properly even under heavy loads on agricultural fields.

The shield is very durable. It is made of durable plastic and includes metal inserts. Weighs no more than eight kilograms and installs quickly.

In this figure you can study in detail the design of the MTZ instrument panel.

The durable shield includes the following mechanisms:

Nuts (1, 4, 37, 32), brackets (3, 12, 23, 25, 35), washers (2, 5, 6, 33, 14);
Cabin shield (39);
Bolts (7, 15), screws (8, 22, 30, 34), harnesses (9, 10);
Handbrake lamp relay (13), screw (16, 21), bracket (17);
Alarm relay (19), plug (20), warning lamp block (24, 26);
Instrument cluster KP-6 (27), MTZ tachometer speedometer (28), casing (29);
Steering column switch (31), control panel (36);
Starter switch (38), seal (40).

Most models of MTZ instrument panels contain:

Voltage indicator.

We have placed the permissible values of this sensor in this table.

Optimal fuel value indicator.
Working fluid temperature sensor for the engine cooling system;
Lamp blocks;
Pressure meter;
MTZ tachometer speedometer (here you will read about repair, installation and spare part design);
Stub;
PU tachospeedometer.

In the instrument panel of the MTZ 80 or other tractor models, three electrical circuit fuses are installed that protect the sound signal, hazard warning lights, windshield washer, side lights and other circuits from overvoltage.

A 60A fuse is also provided to protect the battery circuit.

Advice - try to avoid burning electrical wiring.

Install only fuses recommended by the manufacturer in the tractor instrument panel and other systems.

Do not buy parts with a higher amperage rating, otherwise it will often fail.

Typically, tractor instrument panels last a long time. If you use the part correctly, there should be no scratches, chips or cracks.

The only thing is that the system power buttons may get stuck. Also, in some cases, the MTZ tachometer speedometer malfunctions, showing incorrect values (you can read more about the MTZ tachometer speedometer and its operation here).

In any case, we advise the lido to repair the shield or buy a new one.

In our catalog you will find high-quality tractor instrument panels from the Belarusian manufacturer at the best prices.

Our catalog contains spare parts for both small and large cabins. If desired, it is easy to order an assembled MTZ instrument panel.

Seat height adjustment is carried out:

— to increase the height of the seat — by successively manually moving the seat up;

- to reduce the height - with a sharp lift, the seat moves up until it stops, then lowers (push down) to the lowest position, after which it rises up to the desired lower height.

52 - power (position) regulator switch. It has three positions: right - “positional regulation”, left – “force regulation”; middle - “off”.

53 - handwheel for controlling the speed of correction by the power regulator. When turning the handwheel clockwise, the correction speed decreases, and counterclockwise, it increases.

54 — hydraulic hook grip control handle. The lower position of the handle is “grips under load”, the upper position is “grips free from load”.

55 — handle for switching the rear PTO from independent to synchronous drive. When the handle is moved to the extreme left position (along the tractor's direction), the synchronous drive is activated; when the handle is moved to the extreme right, the independent drive is activated; the middle position is neutral.

56 - handle (Fig. 3) for turning on the compressor. It has two positions: left (arrow on the handle faces forward) - “compressor off”, right (arrow on the handle faces back) - “compressor on”. Turn on the compressor when the diesel engine is not running or at minimum idle speed.

a lock, which in turn consists of a zinc body, retaining rings, locking cylinders and a key.

The wires must be connected according to the color diagram.

Panel for MTZ with large cabin

Since 1980, Belarus MTZ 80(82) tractors began to be equipped with a large observation cabin. In this assembly, they began to install another panel, indicated by catalog article 80-3805010-D1, with autonomous instrumentation (with instrument panel 80-385021-01), which was subsequently installed on tractor brands MTZ 100(102), 1221.

Instrument panel MTZ 80(82) with autonomous devices 80-3805010-D1

The shield is made of composite plastic, is installed on top of the common body of the control devices and is a single inclined plane with a hole for the steering wheel. Three blocks with fuses are mounted under the front front cover of the shield in a separate compartment.

Panel warning lights

The upper part of the instrument panel is equipped with blocks of warning lamps (BKL 3803-03 and BKL 3803-01), which indicate the operating status of tractor systems or individual components.

Signaling lamps of the MTZ 82 control panel

The AP70.3813 device is located on the right side of the panel with the AP70.3709-01 setting panel located below. The sensor display consists of a number of indicators:

Tachometer speedometer for MTZ tractor

digital speed indicator 6 for vehicle movement from 0 to 50 km/h on one display 7 with an hour meter
dial indicator 8 with scale 1 diesel crankshaft rotation speed from 0 to 3500 rpm.
LED scale 4 indicating the rotation speed of a two-speed independent PTO 2.3 tractor
digital counter 5 of the total operating time of the diesel engine from 0 to 9999 engine hours

MTZ 80 tractor tachometer

The tachometer speedometer programming parameters are set by the manufacturer in accordance with the make of the tractor, the rolling radius of the rear drive wheels and the brand of diesel engine. Resetting the tachometer speedometer is only necessary when changing the size of the rear wheels. If it is necessary to completely reprogram the sensor, the settings are carried out according to the instructions in accordance with the tabular data.

Row of toggle switches

The switches are located in the lower left part of the panel:

emergency stop switch 245.3710,
light switch with two positions (I - panel backlight is on, II - car road lights are additionally on) P147M-04.29,
windshield washer switch P150M-14.10,
switch for pre-start electric torch heater P150M-19.44.

Control panel design

In the lower right corner of the panel there is a switch 1202.3704-03 for the instrument panel and starter with a key socket. In addition, the kit includes a remote lever switch for turn signal lights, high-low beam and horn with a bracket for mounting on the steering column. The remaining switches are located on a separate top panel at the front of the cabin ceiling.

MTZ instrument cluster

Thanks to precise sensors, the operation of the system of modern automotive equipment is monitored.

In this article we will look at the design of the MTZ instrument cluster, as well as the optimal performance of lamps.

Most mechanisms include:

Fuel volume indicator (1.1 reserve volume lamp);
Pneumatic system pressure indicator (2.1 lamp turns on when an unsafe pressure level in the pneumatic system is reached);
Voltage indicator (the MTZ instrument cluster also contains a 3.1 module - an additional battery charging lamp);
Coolant temperature gauge (4.1 emergency system lamp);
Engine oil pressure indicator (5.1 emergency lamp);
Indicator of the optimal pressure in the tractor transmission oil.

The divisions are located on the fuel volume indicator scale. There is also a lamp here.

As a rule, the sensor lights up only when the amount of fuel decreases to 1/8 of the total volume.

Therefore, we advise you not to allow the fuel level in the tank to reach a minimum level. Follow the readings of the MTZ instrument cluster (the arrow will be located on the orange indicator).

In turn, the optimal pressure indicator in the pneumatic system has 2 modules:

Worker (green);
Emergency (red color).

The red warning lamp lights up when the pressure decreases to approximately 500 kPa.

The voltage sensor monitors the battery voltage if the diesel engine is turned off. In this case, the starter switch key is in position I.

The zones on the indicator scale will tell you about the state of the power system.

Do not forget that the MTZ 82 instrument cluster indicates a breakdown of the generator drive belt if the battery is not charged.

The engine coolant temperature sensor processes data from the engine block.

Has 3 zones:

Informational;
Emergency;
Working.

The zones have the following colors: green (working), red (emergency), information (yellow).

The oil pressure sensor in the engine lubrication system processes information from the ECU. As in previous elements of the instrument cluster, MTZ 82 is equipped with 2 zones - emergency (red), working (green).

When the pressure drops to 100 kPa, the emergency lamp lights up.

However, if you start a cold MTZ engine, the pressure will reach 600 kPa.

If the emergency pressure lamp turns on while the engine is running, you must stop the engine immediately. After this, we advise you to inspect the systems and eliminate the malfunction.

You can buy the MTZ 82 instrument cluster on our website. The part is very durable and reliable. Rarely fails.

Replacing the shield on the tractor

The electrical system, an important part of which is the dashboard of this tractor, is one of the main elements of its design. At the same time, owners of such devices often have to deal with various malfunctions that make the correct operation of the MTZ impossible.

Most often, you encounter incorrect display of performance indicators when you turn on the ignition or activate certain functions, such as lighting, heating system, or pressing the brake pedal. Such a problem may indicate a serious breakdown hidden in the electrical circuit of the device.

With a high probability, it signals that there is no connection with the positive or negative wire. To resolve, it may be necessary to “ring” the entire wire to find the faulty section.

Often, incorrect operation of devices can be caused by damaged fuses, which will require their immediate replacement. Since repairing individual elements of the dashboard seems to be a complex procedure that will require highly qualified technicians, many prefer to turn to specialists.

Be sure to read: Technical characteristics of the A-41 engine

If the tractor owner wants to restore the element’s functionality on his own, a promising option may be to completely replace the panel and connect it to the MTZ electrical circuit. To do this, you will need to adhere to the following algorithm of actions:

Disconnect the battery from the tractor power supply.
Remove the fastening elements by which the instrument panel is installed in the cabin.
Remove the broken device, replace it with a new one, which will need to be connected, guided by the MTZ 80 electrical diagram.
Install fasteners.

This procedure is quite simple, but is not suitable for those owners who do not have the necessary knowledge about the electrical system implemented in this series of tractors.

____________________________________________________________________________________________

The instrument cluster includes five gauges with five warning lamps, as shown in the figure. Fig.7. Instrument cluster of tractors Belarus MTZ-82.1, 80.1, 82.2 1 – warning lamp for reserve fuel level in the tank; 2 – air pressure indicator in the pneumatic system; 3 – warning lamp for emergency air pressure in the pneumatic system; 4 – fuel level indicator in the tank; 5 – voltage indicator; 6 – unused signal lamp; 7 – warning lamp for emergency engine coolant temperature; 8 – engine coolant temperature indicator; 9 – warning lamp for emergency oil pressure in the engine lubrication system; 10 – oil pressure indicator in the engine lubrication system. The scale of the air pressure indicator in pneumatic system 2 has three zones: - working - from 500 to 800 kPa (green); — emergency (two) — from 0 to 500 kPa and from 800 to 1000 kPa (red). The indicator scale has a built-in warning lamp 3 (red), which lights up when the pressure in the pneumatic system drops below 500 kPa. Voltage indicator 5 shows the battery voltage when the Belarus MTZ-82-1, 80-1 engine is not running, when the starter and instrument switch key is in position “I”. When the engine is running, the voltage indicator shows the voltage in the on-board network, which is set by the generator. The scale of the fuel level indicator in tank 4 has divisions “0–1/4–1/2–3/4–1” (option 1), or “0–0.5–1” (option 2). The indicator scale has a built-in warning lamp 1 (orange), which lights up when the fuel level in the tank drops to 1/8 of the total tank volume. The scale of the engine coolant temperature indicator has three zones: - working - from 80 to 105 ° C (green); - informational - from 40 to 80 °C (yellow); - emergency - from 105 to 120 °C (red). An emergency temperature warning lamp (red) 7 is built into the indicator scale, which lights up when the coolant temperature is 105 °C and above. The scale of the oil pressure indicator in the engine lubrication system 10 has three zones: - working - from 100 to 500 kPa (green); - emergency (two) - 0 to 100 kPa and from 500 to 600 kPa (red). The indicator scale has a built-in warning lamp for emergency oil pressure drop 9 (red), which lights up when the pressure drops below 100 kPa. Blocks of warning lamps Two blocks of warning lamps are installed in the instrument panel of tractors Belarus MTZ-82.1, 80.1. Each BCL includes six indicator lamps and one button for checking the functionality of the indicator lamps. Fig.8. Warning lamp blocks 1, 14 – button for checking the functionality of the warning lamps; 2 – indicator lamp for maximum clogging of the air cleaner filter (orange); 3, 4, 7, 9, 10 – unused control lamps, 5 – control lamp indicating the operation of glow plugs (orange); 6 — warning lamp for emergency drop in oil pressure in the HPS system (red); 8 – control lamp indicator for turning on the high beam of road headlights; 11 – control lamp-indicator of turning on the tractor direction indicators; 12 – control lamp - indicator for turning on the direction indicators of the tractor trailer; 13 – indicator lamp for turning on the parking brake. The principle of operation of the LCL control lamps is as follows: - when you press button 1, all lamps on the left LCL should light up. When you press button 14, all the lamps on the right BCL should light up. If one of the six indicator lamps used (2, 5, 6, 8, 11, 12 or 13) does not light up, it is necessary to install a working lamp or replace the indicator lamp unit (if LEDs are installed); — the indicator lamp for maximum clogging of the air cleaner filter 2 lights up when the maximum permissible level of filter clogging is exceeded and it needs to be cleaned or replaced; — the glow plug operation indicator lamp displays the operation of the glow plugs; — the control lamp-indicator for turning on the high beam of road headlights 8 lights up when the high beam of road headlights is turned on; — indicators 11 and 12 for turning on the tractor and tractor trailer turn indicators operate in a flashing mode when the steering column multifunction switch 1 turns on the right or left turn signal, or when the hazard warning switch 2 is turned on; — the parking brake activation warning lamp 13 operates in a flashing mode with a frequency of 1 Hz when the parking brake activation sensor is triggered; — warning lamp 6 for an emergency drop in oil pressure in the HPS hydraulic system lights up when the oil pressure in the HPS hydraulic system drops below 0.08 MPa (lamp 6 is allowed to light up periodically at minimum engine speed - when engine speed increases, lamp 6 should go out). When installing power steering instead of power steering, indicator lamp 6 is not used. Tachospeedometer AR70.3813 Fig.9. Tachometer speedometer AR70.3813 1 – engine speed scale, min-1; 2 – high voltage indicator in the tractor on-board network (red); 3 – rear PTO speed indicator in 1000 min-1 mode (light indicator); 4 – rear PTO speed indicator in 540 min-1 mode (light indicator); 5 – rear PTO speed indication display; 6 – display (LCD) indicating the total engine operating time and tractor speed; 7 – arrow indicator of engine crankshaft speed. Operating procedure of the tachometer speedometer AR70.3813 On a stopped Belarus MTZ-82-1, 80-1, 82-2 tractor, after setting the starter switch and instruments to position “I”, an indication of the engine operating time in hours (h) appears on display 6. After starting the engine, the pointer 7 moves along the circular scale 1 to indicate the engine crankshaft speed.

At the same time, an indication of the estimated rotation speed of the rear PTO (min-1) appears on display 5 - on scale 3 for the rear PTO in the 1000 min-1 mode and on scale 4 for the rear PTO in the 540 min-1 mode. The rotation speed of the rear PTO is calculated based on the signal from the phase winding of the generator. When the tractor moves, an indication of the estimated tractor speed (km/h) appears on display 6, while the engine operating time indication disappears. Speed readings are carried out based on a signal from a sensor installed on the final drive gear of a wheel rotating at a lower frequency. The calculated speed is slightly higher than the actual speed, because Tractor slipping is not taken into account. If, while the tractor is moving, the numbers “02-07” appear on display 6 instead of speed readings, and after 12±1 seconds the number “0” appears on the right side of display 6, this means that there is no signal from the right speed sensor. The problem needs to be corrected. If, while driving the Belarus MTZ-82.1, 80.1 tractor, the numbers “02-07” appear on display 6 instead of speed readings, and after 12±1 seconds the number “0” on the left side of display 6, this means that there is no signal from left speed sensor. The problem needs to be corrected. There are no speed indications on display 6. To restore speed readings, it is necessary to eliminate the above faults. Indicator 2 for high voltage on-board power supply of the tractor lights up when the on-board power supply voltage is above 18V and goes out when the supply voltage drops below 16 V. While indicator 2 is on, the tachometer speedometer does not function. If the voltage in the tractor's electrical system increases above 18V, the tachometer speedometer backlight lamps may fail if they were turned on. In this case, it is necessary to replace the tachometer speedometer backlight lamps. Combined indicator KD 8083 Fig. 10. Combined indicator KD 8083 1 – high voltage indicator in the tractor on-board network (red); 2 – engine speed indicator (arrow indicator); 3 – rear PTO speed indicator in 1000 min-1 mode (light indicator); 4 – rear PTO speed indicator in 540 min-1 mode (light indicator); 5 – rear PTO speed indication display; 6 – LEDs illuminated in the mode of displaying the driving speed “km/h” and the total operating time of the engine “h” (opposite the corresponding LED); 7 – LEDs illuminated in the mode of programming the coefficients “K”, “R”, “Z” and LED “T” illuminated in the mode of indicating the specified total engine operating time (opposite the corresponding LED); 8 – display (LCD) indicating the total engine operating time and tractor speed. Operating procedure of the combined indicator KD 8083 On a stopped Belarus MTZ-82-1, 80-1 tractor, after setting the starter switch and instruments to the “I” position, an indication of engine operating time in hours (h) appears on display 8 and LED 6, located next to symbol "h". After the engine starts, the engine speed indicator 2 displays the engine speed. At the same time, an indication of the estimated rotation speed of the rear PTO (min-1) appears on display 5 - on scale 3 for the rear PTO in the 1000 min-1 mode and on scale 4 for the rear PTO in the 540 min-1 mode. The rotation speed of the rear PTO is calculated based on the signal from the phase winding of the generator. When the tractor moves, an indication of the estimated tractor speed (km/h) appears on display 8 and LED 6, located next to the “km/h” symbol, lights up. In this case, the engine operating time indication disappears. Speed readings are carried out based on a signal from a sensor installed on the final drive gear of a wheel rotating at a lower frequency. The calculated speed is slightly higher than the actual speed, because Tractor slipping is not taken into account. If 12±1 seconds after the start of movement, or during movement, the “rectangle” symbol is displayed on the right side of display 8, this means that there is no signal from the right speed sensor. If 12±1 seconds after the start of movement, or during movement, a symbol is displayed on the left side of display 8, this means that there is no signal from the left speed sensor. The problem needs to be corrected. There are no speed indications on display 8. To restore speed readings, it is necessary to eliminate the above faults. Indicator 1 of high voltage in the tractor's on-board network lights up when the voltage rises above 18V and goes out when the supply voltage drops below 16V. While indicator 1 is on, the IR does not function. If the voltage in the tractor's electrical system increases above 18V, the IR backlight lamps may fail if they were turned on. In this case, it is necessary to replace the IR illumination lamps.
