WG9921160220
Shacman Sinotruk HOWO FAW Foton Auman Dongfeng
| Attribute | Description |
|---|---|
| Part Name | Clutch Pressure Plate Assembly / Clutch Cover Unit |
| OEM Number | WG9921160220 |
| Alternate Names | Clutch Cover, Clutch Housing, Clutch Kit Core Component |
| Clutch Size | CH430-21 — outer diameter ≈ 430 mm (17 inches) |
| Mounting Type | Bolt-on design (typically M12 or M14 bolts) |
| Operating Principle | Uses diaphragm spring (membrane-type) mechanism for consistent pressure application |
| Material | |
| • Body: High-strength ductile cast iron | |
| • Spring: Heat-treated spring steel (60Si2MnA equivalent) | |
| • Friction contact surface: Wear-resistant coating | |
| Torque Capacity | Designed for engines up to ~1,800 N·m output (typical for WD615/WD618 series) |
| Function | |
| • Applies clamping force to hold clutch disc against flywheel | |
| • Releases pressure via release bearing for gear changes | |
| • Enables smooth start-up and gear shifts | |
| Heat Dissipation | Engineered fins and thermal mass help dissipate heat during repeated operation |
| Condition | Brand new (OEM original or premium aftermarket) |

Professional Installation Required
Requires transmission removal and engine support.
Must be performed by certified diesel mechanics in a clean environment.
Replace in Full Kit
Clutch Disc (e.g., WG9921160210)
Release Bearing (e.g., WG9725160510)
Pilot Bearing (if worn)
Always install together with:
Mixing old and new parts leads to premature failure.
Use Proper Tools
Use clutch alignment tool during installation.
Prevents misalignment and damage to input shaft.
Clean Flywheel Surface
Inspect flywheel for cracks, grooves, or warpage.
Resurface or replace if uneven wear exceeds 0.2 mm.
Check Free Play in Pedal
Adjust clutch linkage or hydraulic master/slave cylinder after installation.
Correct free play: ~10–15 mm at pedal.
Avoid Oil Contamination
Do not touch friction surfaces with bare hands.
Oil contamination causes slippage and rapid wear.
Break-In Period
First 500 km: Avoid sudden starts or aggressive acceleration.
Allows friction materials to seat properly.
Tighten Bolts in Star Pattern
Gradually tighten mounting bolts evenly across the cover.
Typical torque: 35–45 Nm, refer to service manual.
Inspect Release Fork and Sleeve
Check for wear or binding in the fork/guide tube.
Worn components affect disengagement.
Drive Only After System Test
Verify smooth engagement, no noise, and full disengagement before normal driving.
