TCM 15943-80221 Transmission Charging Pump Assembly

The TCM 15943-80221 transmission charging pump is a hydraulic gear pump designed to supply pressurized oil to the torque converter and transmission clutch packs in TCM internal combustion forklifts. It mounts directly to the transmission housing and is driven by the engine via the torque converter hub. The pump housing is constructed from cast iron for dimensional stability and wear resistance under continuous high-pressure operation. Internal gear profiles are precision machined to maintain volumetric efficiency across the operating temperature range. This unit serves as the primary charge pump for the transmission hydraulic circuit, ensuring consistent clutch engagement torque and lubrication flow. Cross-referenced with TCM part numbers 15583-80221 and 124U3-80221, it fits TCM FD50 through FD100 series forklifts with Z7 and Z8 transmission configurations, as well as compatible Heli, Hangcha, JAC, Baoli, and Tailift models utilizing the same transmission architecture.
