Forklift Engine Oil Water Separator Assy CL0002622 – CPCD100

Forklift Engine Oil Water Separator Assembly CL0002622 — CPCD100-QC3K, 4J1-5410541560000 Reference

This is the engine oil water separator assembly (part number CL0002622, reference 4J1-5410541560000) for CPCD100-QC3K 10-ton heavy forklifts. The oil water separator is a critical fuel system component on large-displacement diesel forklift engines: it removes water and particulate contaminants from diesel fuel before the fuel enters the high-pressure injection pump, which on a 10-ton CPCD100 forklift operates at injection pressures exceeding 1,000 bar (14,500 psi). At these pressures, even microscopic water droplets cause cavitation erosion on the injection pump plunger surfaces — the water droplets implode against the metal surface under pressure, creating pits that grow into cracks and cause pump failure. The separator assembly on heavy forklifts typically includes both a filter element (paper or synthetic media) for particulate removal and a water collection chamber with a drain valve for water separation — on a CPCD100 operating in construction, port, or heavy manufacturing environments, the fuel quality is often worse than in warehouse applications because bulk fuel storage tanks accumulate condensation water and rust scale that end up in the forklift’s fuel tank. The CL0002622 is the complete separator assembly — not just the filter element — meaning it includes the housing, mounting bracket, and all connections needed for installation.

New condition, drum-handling equipment forklift attachments type. Part number CL0002622, reference 4J1-5410541560000. Parts for CPCD100-QC3K 10-ton heavy forklift. When replacing the complete separator assembly, transfer the fuel line fittings from the old unit or verify the new unit has the correct thread type and size for your fuel lines. Fill the separator with clean diesel fuel before connecting the fuel lines to minimize priming time. Bleed the fuel system after installation. Check for leaks at all connections after the engine has been running for 5 minutes — diesel leaks at the separator connections are a fire hazard on a hot engine.
