The engines have a mixed (pressure and splash) lubrication system
Under pressure, oil is supplied to the main and connecting rod bearings of the crankshaft, to the camshaft bearings

In this article, we will take a closer look at how to assemble an oil filter with a spacer
Full-flow oil filter with a replaceable filter element "Regotmas 440A-1-06"
On GAZ-5ZA and GAZ-66 vehicles, rubber reinforced cuffs (oil seals) with a spring are used to seal the shafts of the units
During the operation of vehicles, periodically check the leakage of oil or grease through the lip seals.

Wash the bearings in diesel fuel. Check the running surfaces of the outer and inner races and the bearing cage

Schemes for switching on turn indicators are shown in fig. 1 and 2. The sidelights and taillight are switched on by a switch of type P105 on a GAZ-53A car and P118 on a GAZ-66 car

The winch arrangement is shown in fig. 1.
To increase the efficiency of the winch, a globoidal gear is used

The power take-off device is shown in fig. 1
The power take-off is bolted to the gearbox on the right side and serves to transfer power from the gearbox to the winch

The engine cooling system is liquid, closed with forced circulation
The direction of circulation is shown by the arrows in the figure
