Crown Top Lower Drive Housing Gasket – 89-448

Sealing the split line between the top and lower sections of the drive housing on Crown lift trucks, this gasket keeps gear lubricant inside the drive unit and contaminants out under running temperature and load. The drive housing carries the traction gearing in an oil bath, and the gasket at this flange is what stops that oil from weeping past the joint as the unit heats and works. A hardened, crushed, or torn gasket is a common source of a slow drive-unit leak, and it is replaced whenever the housing is opened for gear or bearing service so the joint reseals cleanly on reassembly. Sold individually and weighing about five pounds, it matches the footprint and bolt pattern of the housing split it was cut for. Match the gasket to the drive housing being serviced, since the sealing outline and bolt holes are specific to that unit.
