Hangcha Forklift Transmission Gearbox Housing YQX100-0036 – CPCD50-100R

Hangcha Forklift Transmission Gearbox Housing YQX100-0036 — CPCD50-100R Heavy-Duty 5-10 Ton

The YQX100-0036 transmission gearbox housing is the main structural casing for Hangcha CPCD50 through CPCD100R heavy-duty forklift transmissions. This large-frame cast housing encloses the complete powershift transmission gear train, providing the rigid framework that maintains precise alignment between the input shaft, countershaft, and output shaft bearing bores. For 5-10 ton capacity forklifts operating in ports, steel mills, and lumber yards, the housing must withstand continuous high-torque loads and shock loading during heavy material handling — any housing crack, warp, or bearing bore wear immediately compromises gear mesh across all transmission stages, leading to catastrophic transmission failure.

The YQX100-0036 housing fits the entire Hangcha CPCD50R, CPCD60R, CPCD70R, CPCD80R, and CPCD100R model range — the transmission housing casting is shared across all 5-10 ton R-series forklifts, with internal gear ratios and clutch specifications varying by tonnage class. This housing is specific to the R-series (refined) models and does NOT fit earlier CPCD50-100 non-R variants — those use a different bolt pattern for the transmission-to-engine mounting. The YQX100-series transmission is a purpose-built heavy-duty powershift design, not a scaled-up version of the smaller YQX30-series used in 1-3.5 ton forklifts. Verify your data plate for “CPCD” with “R” suffix and the YQX100 transmission designation.

Replacing this gearbox housing is a full transmission overhaul — the transmission must be removed from a 5-10 ton forklift (the transmission assembly alone weighs several hundred kilograms), completely disassembled, and all internal components transferred to the new housing. Critical procedures: measure all bearing bore diameters in the replacement housing before assembly — oversized bores from casting variations will cause bearing outer race spinning and housing destruction; check shaft end-play after reassembly with a dial indicator to confirm correct bearing preload; pressure-test the assembled transmission for housing porosity at 0.5 bar before installation; and torque all housing bolts to Hangcha specification in the correct sequence.
