HELI Forklift Transmission Gearbox Housing BSX-120M3-82011 – CPCD30

HELI Forklift Transmission Gearbox Housing BSX-120M3-82011 — CPCD20 / CPCD25 / CPCD30

The BSX-120M3-82011 transmission gearbox housing is the main structural casing that encloses the HELI CPCD20, CPCD25, and CPCD30 powershift transmission assembly. This cast housing provides the rigid framework that holds the transmission gear train, shafts, bearings, and clutch packs in precise alignment — it is the foundation of the entire transmission system. A cracked, warped, or worn gearbox housing compromises gear mesh alignment across all transmission stages, leading to accelerated gear wear, bearing failure, and ultimately complete transmission seizure. The BSX-120M3-82011 housing is cast and machined to HELI OEM tolerances with precision bearing bores, dowel pin locations, and mounting face flatness to ensure proper gear train alignment and leak-free operation.

This housing fits HELI CPCD20 (2-ton), CPCD25 (2.5-ton), and CPCD30 (3-ton) diesel forklifts equipped with the powershift transmission. The three models share the same transmission housing casting — the internal gear ratios and clutch pack specifications differ between tonnage classes, but the housing bolt pattern, mounting dimensions, and bearing bore sizes are identical across the CPCD20-30 range. However, this housing does NOT fit the smaller CPCD10-18 models or the larger CPCD35 and above — those use different transmission housing castings with distinct bolt patterns and shaft center distances. Always verify your data plate for CPCD20, CPCD25, or CPCD30 model designation.

Replacing a gearbox housing is a major transmission overhaul procedure. The transmission must be completely removed from the forklift and disassembled — all gears, shafts, bearings, clutch packs, and seals must be transferred to the new housing in the correct order and orientation. Critical checkpoints: inspect the replacement housing’s bearing bores for any casting flash or machining debris before assembly; measure all shaft end-play after reassembly to confirm correct bearing preload; verify that all dowel pins are fully seated and not worn; and pressure-test the assembled transmission for housing porosity or gasket surface leaks before installing into the forklift.
