Where This Part Is Used
Used on compatible XCMG truck-crane carriers to drive the main hydraulic pump when crane operation is selected.
Failure Clues and Workshop Check
Failure to engage, gear noise, oil leakage, overheating or low pump output may relate to the PTO, engagement control, lubrication or coupling. Confirm the transmission side before replacement.
Installation and Handover
Inspect mating gears and sealing faces, use the specified gasket or sealant, set backlash where required and verify oil level and engagement before connecting full hydraulic load.

Buyer FAQ
Can a PR70 PTO be selected by model name only?
No. Multiple interfaces, ratios and output styles can exist under the same family designation.
What causes repeated PTO gear damage?
Incorrect backlash, pump misalignment, engagement under load or insufficient lubrication are common causes.
Export Packing
Machined faces and shafts are rust-protected and capped; the heavy unit is restrained in a reinforced crate.
