Xinchai 4D32 Fuel Filter Assembly 4D32ZT31-24100 — HELI, Hangcha, JAC, TCM, Tailift, Liugong Forklift, 100% Original

This is the fuel filter assembly (part number 4D32ZT31-24100) for Xinchai 4D32G diesel engines — the final fuel filtration component between the fuel tank and the injection pump that removes microscopic particles from the diesel fuel before it enters the precision-machined injection system. The 4D32G engine powers HELI, Hangcha, JAC, TCM, Tailift, and Liugong forklifts in the 2-3.5 ton class, and its injection pump operates with internal clearances of 2-5 microns — particles larger than this score the plunger-and-barrel surfaces, creating internal leaks that reduce injection pressure and eventually cause pump failure. The fuel filter captures contaminants that pass through the upstream water separator (coarse filtration) and any particles that enter the fuel during storage, transfer, or from corrosion inside the fuel tank and steel fuel lines. A clogged fuel filter — the most common cause of hard starting, power loss under load, and engine stalling on diesel forklifts — restricts fuel flow to the injection pump. The injection pump cannot generate design injection pressure if the inlet fuel supply is restricted, because the pump’s internal transfer pump draws fuel from the tank through the filter — a restricted filter creates a vacuum on the pump inlet that reduces filling of the high-pressure plunger chambers, causing low injection pressure and poor atomization at the injector nozzles. The result is incomplete combustion, black smoke from the exhaust, reduced power, and increased fuel consumption — all symptoms of a $10 filter that needs replacement, not a $2,000 injection pump rebuild.

Xinchai brand, 100% original quality. Manufactured in Chongqing, China with machinery test report and video outgoing-inspection provided. New condition. 5 kg gross weight (15×17×6 cm package). MOQ: 1 piece, delivery within 7 days. Engine model 4D32G, diesel engine type, engine repair parts classification. When replacing, fill the new filter with clean diesel fuel before installation — a dry filter can cause the injection pump to run dry during priming, causing pump wear. Apply a thin film of diesel to the O-ring seal. Hand-tighten until the seal contacts, then 3/4 additional turn. Bleed the fuel system after installation. Check for leaks at the filter seal after the engine has been running for 5 minutes. Compatible forklift brands: HELI, Hangcha, JAC, TCM, Tailift, Liugong.
