The WG9700290010 is the HW50 power take-off (PTO) assembly used on SINOTRUK HOWO trucks with HW15710 / HW19710 series gearboxes. Mounted on the rear bottom right of the gearbox, it takes power from the mainshaft gear and drives the dump-truck hydraulic pump through a FAST-type companion flange. This is the assembly version – PTO unit plus output shaft – ready to bolt on.

Key Features

Genuine SINOTRUK HW50 PTO, cast FRT housing as supplied on HW series turnover.
0.924 direct ratio keeps hydraulic pump speed close to engine speed – ideal for tipping and mixer duty.
Pneumatic shift with STEYR type indicator switch: fast engagement, clean disengagement under load.
Sold complete with output shaft (spline) and lubrication pipe, so no extra shaft sourcing needed.

Signs of Wear – When to Replace

Hydraulic pump speed drops or the tipper body lifts slowly when the PTO is engaged.
Grinding or whine from the PTO housing when engaging with the engine running.
Oil leaking from the output shaft seal or the housing joint.
PTO will not engage or keeps jumping out – worn shift fork or gear dogs.
