U-Cup SealThis u-cup seal prevents lubricant loss and keeps contaminants out of rotating assemblies on forklift axles, transmissions, and engine components. Sold as an aftermarket replacement, this part number AC1008683 ships from SCR Forklift Parts and is intended to match OEM fit and function. Technicians replace seals whenever a wheel hub, transmission case, or engine cover is opened, since reusing an old seal almost always leads to a comeback leak. Forklift fleets and rebuild shops order seals like this in volume to keep PM jobs moving and to stop drips that create slip hazards on warehouse floors.Aftermarket replacement part, cross-references original part number AC1008683.Need help confirming fit?
