GAZ 66 technical characteristics: performance characteristics, engine, cabin

Standard mechanical winch

We do not sell this winch. The
advantages are high reliability and rare breakdowns. The disadvantages are heavy weight, low traction and the ability to work only when the engine is on.

Tuning and restyling

Due to the fact that the GAZ-66, including a new one from conservation, is relatively easy and cheap to get, it has undergone numerous alterations and tuning by auto repairmen. This is not least due to the fact that the chassis is sometimes left completely untouched, changing only the appearance. Another plus is that the ZMZ-513 engine is still in production.

Often tuning comes down to installing wheels of larger diameter with developed lugs. Tires can be low pressure, arched, with which the “shishiga” loses speed, but certainly will not “sit down” in any swamp.

Various body kits, guardrails and, of course, special paint are also added to the brutal all-terrain vehicle.

In a more serious modification, the truck is turned into a huge jeep. One of the first such attempts was made by the Retro-Style studio in 2002. The car received its own name “Barkhan”, and under its appearance it is quite difficult to discern the chassis of the “Gazik”.

The same company, five years later, released a new monster, this time even more comfortable, called “Bulat”.

But now the products are not from a commercial office, but from an ordinary municipal enterprise of the Krasnoyarsk Railway. The appearance is unsightly, but the budget is an order of magnitude smaller - only about 160 thousand rubles. But it will get to any point on the listed paths without any problems.

Electric winches in place of the main one

Electric winches are lighter, have more traction and are not tied to engine operation.

Master Winch E15000

The winch has dust and moisture protection according to the IP68 standard. The drum sides on this model are increased in height to prevent damage to the winch when winding the cable on one side. The manufacturer provides a 2-year warranty.

Octopus 16000

SPRUT 16000 is a 12-volt automotive winch manufactured in Ulyanovsk. Designed for use on heavy cargo SUVs, for example GAZ-66, SADKO. Powerful cast iron winch. Not afraid of moisture and other unpleasant conditions.

Runva EWN 17500 U

This model is one of the industrial winches. High thrust is achieved at the cost of low speed.

Runva EWB 20000 U - Elektrolebedka.ru recommends!

This model is ideal for all-terrain trucks for conquering off-road conditions, unlike others that are more tow trucks, it has very good moisture protection according to the IP67 standard.

ComeUp Seal Gen2 16.5

This model has IP68 dust and moisture protection, allowing the winch to operate submerged under water. Long duration of continuous operation, which is achieved by a reliable motor, proper wiring and the presence of temperature sensors.

Description of the base model

The platform for the GAZ-66 all-terrain vehicle was the GAZ-62, assembled in the fifties at the plant in Gorky.

This vehicle had a cabin design characteristic of that time with a fabric roll-up roof and removable door extensions.

The creators of the new all-wheel drive vehicle have retained the general layout of the cabin, located above the engine. Only now it has become all-metal.

The spare tire was placed vertically behind the cab, in front of the body. As a result, while the overall dimensions of the entire vehicle were shortened, it was possible to increase the size of the loading platform and lower its landing, thereby making loading/unloading easier.

The truck bed was made of metal with wooden slatted and folding sides on the rear side. The back had folding benches for transporting people.

The first basic GAZ-66-1 had a carrying capacity of two tons. Various modifications on this chassis were produced until the mid-eighties.

The main advantages of the Ural-6464 truck are presented in our review.

And here the technical characteristics of Kegel semi-trailers are described.

During this time, for the needs of the Armed Forces, agriculture and areas with difficult roads, such modifications were created as:

• "66A" with winch;
• “66E” or “66-03” - a machine whose equipment was shielded;
• modification intended for landing from a military transport aircraft, marked “66B” . It had a folding roof, a folding front frame with triplex and a RU with a folding column;
• single test samples - GAZ-4 with a 6x6 wheel arrangement and "66P" as a truck tractor.

A distinctive feature of the first GAZ-66-1 cars was the lack of automatic air pumping into the wheels.

In the mid-eighties, a modernized version of this all-terrain vehicle came off the assembly line under the label GAZ-66-11.

A compressor powered by the engine was installed on it to automatically maintain the required pressure in the wheels, which, according to reviews from the owners, is quite convenient.

Thanks to the technical characteristics of the car, such as a load capacity of four tons, it was possible to install KUNGs and special equipment in different configurations on the GAZ-66 base. In the books you can find the following car parameters:

• The geometric dimensions of the vehicle are 5,655 (without special equipment in the form of a winch) x 2,322 x 2,490 (in the cabin) in millimeters.
• Ground clearance is 315 mm.
• The largest possible weight of the machine is 5,940 kg.
• The wheelbase of this car is 3,300 mm, the track is 1,800 mm.
• The turning radius provides good maneuverability and is 9.5 meters, which is less than many smaller passenger cars.
• Eighteen-inch tires and sealed machine and engine units provide the ability to ford a depth of 80 cm.
• As transmissions — a synchronized gearbox with four gears and a transfer case with direct and reduction gears, which also has the ability to disengage the front axle.
  Single disc clutch. Forces are transmitted using three shafts and six cardans.

  Differentials have the ability to increase friction, cam type. Since the front wheels are driven, CV joints are used in their drive.

• Suspension front and rear is dependent, leaf spring. The ends of the springs are on rubber supports. Both axles have shock absorbers.
• Steering - worm with roller. A hydraulic booster is installed on the switchgear.
• The drive of the brake system is made with a hydraulic vacuum booster. Brakes on wheels are of shoe type.
• Starter ST-130B, battery 6-ST66-EM. On-board voltage is 12V.
• The fuel tanks can hold 210 liters.

Hydraulic winches

The advantages are a long service life, stopping during overload, constant powerful traction and the ability to work continuously for a long time. Disadvantages: complicated installation, high price, inability to work with the engine turned off.

Hydraulic Autospas LPG45I “Buffalo”

One of the most inexpensive and compact hydraulic winches. The declared pulling force is the same as on a standard winch. If you decide to switch to hydraulics, but don’t want to invest heavily, this is an excellent choice.

Hydraulic Runva HWN 10000 A / Hydraulic Runva HWX 12000 A - Elektrobedka.ru recommends!

This kit is good because it already includes a control system via remote control. All you have to do is purchase a suitable pump.

Hydraulic Autospas LPG81I “Buffalo”

Has a pulling force of 8172 kg / 18000 lbs and a high cable winding speed. Complete sealing provides an undeniable advantage in terms of reliability.

Hydraulic ComeUp Badger 15

A powerful winch with the ability to adjust the oil supply and pressure in the system, which changes the traction force and the speed of winding the cable.

Design features of the transfer case

The transfer case on a car is designed to amplify torque and distribute it, as well as transmit it to the front and rear axles.

In addition, the RC “66-11” has a design for disabling and engaging the front drive axle. Structurally, it includes:

• a drive shaft on which there is a movable gear for connecting direct and reduction gears;
• intermediate shaft . It also has gears. One wheel engages a downshift, the second, movable, serves to engage axles;
• there is a drive shaft for the rear axle ;
• front axle drive shaft;
• control mechanism having shift levers and rods.

For vehicles operating in particularly difficult conditions, an additional gearbox with two reduction gears is installed on the transfer case to further increase the traction forces of the drive wheels.

Transfer cases for GAZ-66 today are sold at prices starting from 12 thousand rubles.

Auxiliary winches

Can be mounted from behind and used through amplification blocks.

Electric Winch 12000 lbs

A huge plus of this winch is the price. They prefer to install this winch as an additional one in the rear of the machine. It will be difficult for her to pull out a deeply embedded Shishiga, but it can help if the situation is not so critical.

PRO-TOP 12500 lbs

Structurally similar to cheap Electric Winch winches, but has a number of improvements. Rubber seals are installed that provide better moisture protection, a powerful 6.5 hp motor with radiator cooling, a monosolenoid in a waterproof block, improved remote controls (wired and radio), easy free unwinding and other advantages.

Operating and repair instructions

While using the vehicle, it is necessary to adhere to safety regulations, promptly repair detected breakdowns, and replace consumables and technical fluids. All maintenance and care operations are described in the operating and repair instructions for the truck.

Maintenance of performance leads to an increase in the service life of the vehicle, reliable and safe driving.

Maintenance and routine repairs of the GAZ-66 come down to checking the operating condition, adjusting parts, and diagnosing systems.

To repair a truck, contact specialized workshops or perform technical work yourself, according to the repair manual.

How to bleed the brakes

When the machine is used for a long time, the friction linings of the brakes wear out. At the same time, the gap between them and the drums increases, which leads to poor pedal performance during braking and constant and strong squeezing of the clutch. To eliminate the problem, bleed the brake system. The current brake adjustment is aimed at restoring the clearance.

You need to bleed the brakes on a GAZ like this:

• First you need to disconnect the eccentric bolt of the intermediate lever from the pusher device.
• Remove the brake master cylinder.
• Separate the pads.
• Check all pedal positions.
• Install the pusher until it stops.
• Reassemble the parts in reverse order.

How to adjust valves

Valve adjustment sequence:

• Remove the rocker cover.
• Remove the spark plug for the first cylinder.
• Set the piston to top dead center (TDC).
• Rotate the crankshaft until the pointer on the clutch housing aligns with the flywheel ball.
• Check the gap with a feeler gauge. It should be 0.25-0.3 mm on a cold engine. If necessary, adjust by turning the adjusting screw.
• Install the parts in reverse order.

How to set the ignition

Algorithm for installing the ignition:

• Turn out the spark plug of the first cylinder.
• Close the hole for the spark plug with your finger and turn the crankshaft until the compressed air comes out.
• Remove the hatch cover on the crankcase clutch and observe the marks on the engine flywheel.
• Rotate the crankshaft until the pointer on the clutch housing coincides with the ball cased into the flywheel.
• Install the distributor drive.
• Check and adjust the gap in the breaker.
• Insert the distribution mechanism into the drive hole and secure with a screw.
• Connect the high and low voltage wires from the ignition coil and the high voltage wires from the spark plugs in the order 1-5-4-2-6-3-7-8.
• Set the ignition timing.

How to bleed the clutch

Correct clutch is to set the free play of the outer end of the release fork to 4-5 mm.

The clutch stroke is adjusted as follows:

• The release spring is detached.
• The stroke is measured. If it is less than the set parameter, the locknut is loosened and adjusted by rotating the pusher.
• Put on the spring.

Noise during operation, knocking noise during sudden changes in rotation speed, difficult gear shifting or self-switching of direct transmission may be associated with problems in the transmission. In these cases, the transfer case and driveline are repaired.

How to set up a carburetor

Tuning the carburetor means adjusting its basic parameters, checking the fuel level in the float chamber and the tightness of the float and fuel valve.

The basic parameters must be configured as follows:

• Adjust the timing of turning on the economizer.
• Check the valve for tightness.
• Check the performance of the accelerator pump.
• Calculate the throughput of the jets using special devices.

How to reduce fuel consumption

If you turn on the front axle of a truck with a gasoline engine, you can reduce fuel consumption by up to 10%. The reduction gear is rigidly connected to the intermediate shaft. The movable gear for engaging the front axle is mounted on the splines. When you move it in the opposite direction, the bridge turns on. When moving forward, the flywheels of the drive shaft contact the elements of the intermediate shaft, thereby activating the reduction gear.

Technical characteristics of the GAZ-66: dimensions, weight and other operating parameters of the machine

In the second half of the 20th century, for thirty-five years, GAZ produced one of the most successful cars of Soviet times in Gorky - a truck with two axles and all-wheel drive of the GAZ-66 brand.

Between 1964 and 1999, just under one million of these vehicles were produced in various versions.

Advantages and disadvantages of the model

Main advantages:

• best cross-country ability among Soviet wheeled vehicles;
• a unified chassis on which it was convenient to mount various types of special vehicles;
• motor power;
• good visibility and small dimensions of the machine due to the cabover layout;
• stability due to a balanced center of gravity;
• large load capacity.

Main disadvantages:

• high fuel consumption;
• inconvenient gear shift lever;
• vulnerability to anti-vehicle mines.

Considering how much the GAZ 66 weighs and how much cargo it lifts, it was a trouble-free and powerful vehicle for transporting and towing a wide variety of equipment, equipment, and passengers. A large number of different modifications is the best proof of its functionality.
