description

This friction disc uses non-band friction material with steel core and cooling grooves for heat dissipation. Worn, burnt, delaminated or broken splines cause steering slip, pull, weak brake and high oil temperature, clutch failure under heavy load.

Part No.: 9W-9856
Part Name: friction disc (steering clutch disc)
Material: Friction material + steel core
OD: 431.9 mm, Thickness: 5.6 mm
Installation Position: Dozer steering clutch pack
Matching Parts: steering clutch plate, piston seal ring, return spring, transmission oil selected as overhaul set on demand

Application Scenarios

Fit for CAT D8L/D9L/D9N/D9R/D9T/D10N/D10R/D10T track dozers, 589 pipelayer. Suitable for mining and heavy earthmoving. Used for steering clutch overhaul for slipping and brake failure.

FAQ 

Q: Can slightly darkened disc with remaining thickness keep working?
A: Not recommended. Discoloration means overheat, friction performance drops and slip comes soon.

Q: What risk if only friction discs are replaced and old steel plates kept?
A: Scored old steel plates wear new friction discs rapidly and cause burn again.

Q: What happens if stacking order is reversed?
A: Wrong clearance leads to unstable pressure, weak steering and quick clutch burn.

Q: What risk if cooling grooves are blocked?
A: Poor heat dissipation causes high temperature and disc burn.
