Product Overview
A worn pump can leak coolant, develop bearing noise or play, and lose the ability to circulate enough coolant under sustained load. Replacing it restores coolant flow through compatible Perkins 400-series engines.
Perkins service information cross-references older 145017730/145017950/145017951/U45017952 numbers to later pump kits such as U45011050 for several build families. Build-code matching matters: HL is associated with 403C-15, HP with 404C-22, HR with 404C-22T and KR with 104-22.
