Control of the snowmobile by turning the front skis. Control system cable. To reduce effort when performing a maneuver on the steering wheel put the chain block. Steering column with a drum for reeling the cable is attached to the body by two brackets.
Transverse thrust ensures that the rotation of the skis at the desired angle synchronously in the direction of rotation of the steering wheel.
Traction of the propeller and braking the snowmobile allows you to adjust the speed.
In the cab on the floor placed the gas pedal and brake pedal and delay. The latter is worth much. It is used to release the sled. In Parking lots, especially on loose snow and cheese, soles of the skis freeze to the snow, with one thrust of the propeller to disrupt machines with not enough space. To break thin ice crust formed on the soles of the skis, it is necessary to slightly shift the ski to the side. The delay pedal is connected to a cable from the upper link right rear strut. Resting on the pedal, the driver compresses the spring of the shock absorber and thereby tilts the car on Board. A few pushes is enough to rock the car when it shifted to the sides and skis, Razroev holding their icy crust.
In the sled mounted serial car engine capacity of 50 HP at 2800 Rev/MIA’s with water cooling and standard units. Torque is transmitted to the propeller through a gear reducer, mounted on the cylinder block and the crankcase (clutch removed). The gearbox has two cylindrical gears. A small pinion gear on the flange of the engine crankshaft. The driven gear of larger diameter (gear ratio 0,78) placed on the shaft of the propeller, which is installed on two (bearing and bearing) ball bearing, planted in the socket housing and its cover.
The propeller blades Ø 2.35 m develops traction 205-210 lbs. Shaft located in the gear casing, above the crankshaft. This allowed to lower the engine down on the amount of center-to-center distances between the shafts and thereby reduce the overall center of gravity of the machine and to give it greater stability, especially when driving with a side roll.

The motor reducer is mounted on the sub beam of the pylon and attached at four points with paws available on the engine block and the gear housing. The front of the engine on the front ends of the beams fixed automobile water radiator. Fuel tank capacity 80 l located behind the driver’s cabin, inside the case. The tank is installed on the lodgment has the filler neck made on the plating inside the pylon.
Of special equipment the following should be noted. The upper hull plating above the front cab is simplified turret ring for mounting a machine gun. The machine gun rotates freely, providing horizontal angle of fire up to 300° and elevation angle to 14°. Under the bow plating on a specially made shelf is placed on-Board the ammunition — 10 stores of ammunition for the machine gun and grenades for close combat.
Snowmobile RF-8-GAZ-98 was modification made in 1942-1943 military engineers of brothers Ivan and Alexey Beskurnikov. In one embodiment, under engine pylon was replaced with a tubular sub frame. The snowmobile with an index of GAZ-98K car engine replaced aircraft M-11 110 HP, which made the car more dynamic. Based on the GAZ-98 was created by a staff variant with enclosed cockpit (limousine); this car had no weapons.
