Hydro coupling K-700 fan drive, 240B-1318010, Kirovohrad region.

Hydraulic coupling of the fan drive for engines produced by YaMZ and TMZ (8481, 8421, 8423, 240B, 850) Application K-700, K-701, PK-6

The fan drive is completely unified with the hydraulic coupling of the fan drive. The design of the proposed fan drive is simple and reliable in operation and is a fixed axis of the drive on which the rotating bearing housing is mounted on bearings. On the outer surface of the case, there are 5 grooves for the drive belts of the fan, generator and air compressor. Rotation from the crankshaft pulley is transmitted to the bearing housing and further through the bearing housing cover, which is also the hub of the fan impeller, to the fan impeller. The drive shaft is attached with 4 M18 bolts to the end plate, which in turn is attached with 4 M14 bolts to the cylinder block on the standard mounting points of the hydraulic clutch.
