Sinotruk HOWO
| Attribute | Description |
|---|---|
| Part Name | Power Take-Off (PTO) Assembly / Gear-Driven PTO Unit |
| OEM Number | WG9700291033 |
| Manufacturer Model | HW70YH-F101 (commonly marked on housing) |
| Mounting Type | Side-mounted — bolted directly to the side cover of the transmission |
| Operation Method | Pneumatically operated — controlled via cab switch and air pressure |
| Drive Type | Gear-driven — engages with output gear inside the transmission |
| Speed Ratio | Matches OEM configuration; typically synchronized with transmission output (e.g., 1:1 or stepped ratio) |
| Output Shaft Type | Spline shaft (standard), compatible with hydraulic pump couplings |
| Material | |
| • Gears & Shaft: High-strength alloy steel (carburized and hardened) | |
| • Housing: Durable cast iron or aluminum alloy casing | |
| Function | Transfers engine power from transmission to auxiliary equipment via rotating output shaft |
| Lubrication | Lubricated by transmission gear oil — no separate oil fill required |
| Condition | Brand new (OEM fresh stock or premium aftermarket) |

Professional Installation Required
Involves removing transmission side cover and aligning PTO gear with internal splines.
Must be performed by certified diesel mechanics familiar with drivetrain systems.
Verify Transmission Compatibility
Confirm your truck uses an HW-series transmission (e.g., HW25712X).
Check if the transmission has a pre-machined PTO opening.
Match Spline Count & Rotation
Ensure output shaft matches the driven equipment’s coupling (e.g., 8T, 10T, 14T splines).
Verify clockwise (CW) or counter-clockwise (CCW) rotation requirements.
Use Correct Air Control System
Connect pneumatic lines to the vehicle’s air supply circuit.
Install appropriate solenoid valve and dash switch for activation.
Follow Safe Engagement Procedure
Engine at idle speed
Clutch disengaged
Vehicle stopped
Engage only when:
Avoid sudden engagement under load — causes gear damage.
Ensure Proper Lubrication
PTO runs on transmission oil — maintain correct oil level and quality.
Use GL-5 85W/90 or equivalent gear oil.
Check for Oil Leaks After Installation
Inspect gasket seal between PTO and transmission.
Replace O-rings or seals if leaking occurs.
Inspect Mounting Bolts Periodically
Tighten to recommended torque (~80–100 Nm) every 50,000 km.
Vibration can loosen fasteners over time.
Avoid Continuous Overloading
Do not exceed rated power draw — can cause overheating and premature failure.
Storage Advice
Store upright in dry indoor environment.
Plug openings to prevent dust/moisture entry.
