Oil PumpThis oil pump (part number AC15000-B3000) is an aftermarket replacement used in forklift engines or transmissions to circulate lubricating oil through the assembly. Pumps wear internally, lose pressure, and eventually cannot maintain the oil flow the engine needs at idle and under load. Engine rebuilders replace the pump during major overhauls or whenever oil pressure testing confirms internal wear. Installing a fresh pump restores correct oil pressure and protects the entire engine investment from the rapid wear that follows low lubrication.Aftermarket replacement part, cross-references original part number AC15000-B3000.Need help confirming fit?
