In early 1945, the Bureau of the plant began designing a three-axis machine, later called the ZIS-151. The first two samples were built in 1946 — one with a gable of the rear wheels and the other with a pent. In the summer of 1947 began comparative tests, which along with a couple of ZIS-151 and the triaxial part of the lend-lease International and Studebaker. The best patency demonstrated all-wheel drive ZIS-151 with single tires, which the rear wheels followed the trail left front, which required less energy for the laying of track. But the representatives of the Ministry of defence for unknown reasons, were in favour of the production of machines with saddle rear. By the way, in the near future, the factory has launched production of the all-wheel-drive ZIL-157 single scheme.

Well, the ZIS-151 was, thus, the country’s first three-axle four-wheel drive vehicle wheel formula 6×6. Serial production of this car lasted from 1948 to 1958. On its base was created fighting machine of jet artillery, armored personnel carriers, large floating cars (BAS), tankers and a number of other military and civilian vehicles.
In 1957 instead of the ZIS-150, the plant supplied to the conveyor ZIL-164, which practically did not differ from the predecessor, but had some differences from the “one hundred fifties” — reinforced frame, more powerful engine with modern carb, telescopic dampers, etc.
The design of the ZIL-164
ZIL-164 was a truck with a triple all-metal cabin and wooden platform with three open sides.
Car engine — carburetor, in-line, six-cylinder, four-stroke, Nizhnekamsky, displacement 5,55 liters compression ratio is 6.2. Maksimalna engine power — 100 HP at the engine speed of 2800 rpm./min.
The engine cylinders are arranged in one unit, made of cast iron with sump. The plane of the connector of the crankcase is below the axis of the crankshaft. Around the cylinders in the block has a water jacket. On the engine block is mounted on the gasket a common cylinder head with water jacket, which houses the combustion chamber. The head, made of aluminum alloy, is fixed to the block by bolts and studs.
Pistons with a flat bottom are cast from aluminum alloy. On top of the piston has three compression and one oil control ring.
The crankshaft made of carbon steel, shakes his subjected to surface hardening by high frequency currents. The engine shaft rotates on seven bearings with thin-walled steel liners with babbit pouring.
The flywheel is secured by six bolts on the flange of the rear end of the crankshaft.
The engine of the ZIL-164
The front shaft is fixed on the steel dowel camshaft gear, oil slinger and the pulley of the fan. From the bottom to the crankcase of the engine attached to the pads pressed steel sump.
The camshaft is made of carbon steel mounted on four steel bushings with Babbitt pouring. In the middle part of the shaft there is a gear drive oil pump and distributor, the rear portion is eccentric to drive the fuel pump, and front cast iron gear meshed with the gear of the crankshaft.
The engine is mounted on a frame on three legs with rubber cushions.
The engine cooling system — forced, closed. Radiator tubular-plate type fixed to the frame through rubber cushions. Thermostat — odnoklapannaya. Shestilopastnye the fan rotates in a housing attached to the radiator. The actuator of the radiator and water pump — single wedge-belt from the crankshaft pulley.

The engine lubrication system — combination: pressure lubricated main bearings and the rod bearings crankshaft, bearings, camshaft, camshaft gear and the drive shaft of the dispenser; to the other friction surfaces the oil is fed by gravity and spray. Oil filtration — double.
On car ZIL-164 is installed dry double-disk clutch. In the future when the next upgrade (on ZIL-164А) clutch replaced a single disc with peripheral spaced springs and driven off.
Transmission — five-speed, and fifth gear — accelerating, i.e. when enabled, the secondary shaft of the box rotates faster than the crankshaft of the engine.
The car is dual main gear assembled with the differential in the crankcase is cast from ductile iron. Rear axle beam also cast from ductile iron. In the side of the beam sleeve is pressed and fixed with fixing screws steel pipe, the ends of which serve as bearings for wheel bearings. The rear hole in the beam closed steel stamped cover, fixed to the beam with screws. Gear ratio of a transmission of 7.63.

The vehicle frame consists of two fabricated steel longerons of channel section of variable profile and cross-beams United by rivets. In the front part of the frame is fixed the bumper and tow hooks, rear tow gear with hook and latch.
Front axle is a steel beam I-beam attached to the frame on two longitudinal semi-elliptic leaf springs. The ends of the springs mounted in the brackets of the frame on rubber pads. In the front suspension included piston shock absorbers (in the future, the ZIL-164А used telescopic hydraulic shock absorbers, double-acting). Front ends of rear springs attached to the brackets of the frame fingers and the back with earrings with two fingers each.
Disc wheel with a flat rim have a removable bead ring with key ring. Rear wheel — gable.
The steering mechanism of the vehicle is a pair of worms techgravy roller, wherein the worm is positioned in the housing on tapered roller bearings and the roller rotates on two bearings.
Brake system of a vehicle comprises a foot brake actuator, acting on all wheels, manual vector-borne and Central brake. Air brakes have a high effectiveness with small effort on the pedals, which greatly facilitates the operation of the vehicle.
