A little history of the Gas 66 yamobur
Active production of Gas 66 vehicles took place in 1960 - 1990, but even today they are in great demand due to their simple and reliable design, which allows them to perform complex types of work, as well as high quality production.
In support of these words, some facts can be cited - for example, the fact that the Gas 66 car was twice awarded a gold medal - in Moscow and Leipzig, and was also awarded the state quality mark. During its active production, it was exported to all socialist countries. Gas 66 was developed for military needs and the priority task in its design was to ensure high maneuverability and the ability to use in difficult conditions. This goal was achieved through the use of tires in the design, in which the pressure level can be changed using a special compressor, as well as through other functional features. For some time this car was used for military purposes, but later, when it became clear that it had an insufficient level of safety for such use, other uses began to be found for this car. One such use is to use it as a base for a drilling rig. High cross-country ability has become the main distinguishing feature and advantage of the gas drill. Its technical device allows drilling to be carried out off-road and in hard-to-reach places and is suitable for use when access to the drilling site is difficult on the construction site. The very first Gas pit drill was a pit drill, also installed on the chassis of a Gas car (it was a Gas 67 car). It was highly functional, but was not used to its full potential, mainly used for landscaping work.
Modifications and homemade products based on the car
After the modernization of the GAZ-66, modifications with specialized bodies became widespread in the national economy. The following machines stand out in particular:
- sewer truck ANM-53;
- fire installations ATs-20, 30;
- ambulance tow truck AS-66;
- auto-dressing AP-2;
- oil tanker MZ-66;
- isotherm van GAZ-2766.
Many craftsmen are able to remake equipment using the chassis of a military vehicle. For example, on domestic roads you can find an SUV converted into a Jeep.
Dump truck
A representative of the equipment is the GAZ-SAZ-3511 - an all-wheel drive dump truck based on the 6631 modification with a PTO, double rear axle tires and a diesel engine with a long service life of up to 150 thousand km. There is no centralized tire inflation mechanism. A dump body with a volume of 5 m³ unloads bulk construction and agricultural materials in 3 directions. By installing additional sides, the capacity is doubled. The lifting mechanism is hydraulic.
KUNG
The KUNG is a closed-type frame-metal template van body made of steel channels and angles. The structure is sheathed on the outside with aluminum sheets and sealed inside with plywood treated with varnish.
Internal components of KUNG:
- heating and ventilation system;
- filter and ventilation unit;
- lighting;
- household equipment;
- sleeping places.
An example of a model with a sealed van is modification 6611.
Firefighter
In total, there are 9 versions of fire engines on the 66th model chassis. The most common is the AC-30 tank truck based on 6601. The specialized equipment includes:
- water tank coated with epoxy enamel, capacity 1500 l;
- fire pump PN-40 with a manifold and foam mixer;
- sleeves with a diameter of 51 and 66 mm;
- trunk;
- ladder.
Fire-technical weapons are used to extinguish fires and carry out emergency rescue operations both in urban areas and in off-road conditions.
Drilling rig
The UGB-50 drilling rig based on the 66th truck is designed for horizontal drilling of hydrogeological wells for the purpose of studying soil, searching for mineral deposits, and water intake. Geological exploration is carried out by core sampling using the shock-rope method. The drilling depth of the auger reaches 100 m.
Manipulator
The body of the manipulator is a metal platform with high side sides and an opening rear one. A crane-manipulator is mounted at the front of the upper part of the chassis, which is used to move, lift and transport goods.
The best option for GAZ is Japanese equipment Tadano-Z290 with a minimum reach of a 3-section boom of 2.95 m, a radius of 8 m. The mechanism is capable of lifting a load weighing up to 4 tons.

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.
How much does the base model and its modifications cost?
Basic models of a truck can be purchased at a price of 150-400 thousand rubles. depending on the year of manufacture, mileage and storage methods. The cost of modification without additional equipment in working condition is 130 thousand rubles. A GAZ-66-15 car with noise-proof electrical equipment and a winch is offered on the secondary market for 300 thousand rubles. KUNG vans are popular. They cost about 400 thousand rubles.
Recently, master motorists put up for sale converted powerful all-terrain vehicles based on the GAZ-66. Their cost reaches 1 million 200 thousand rubles.
