description

This wet multi-disc transmission clutch disc consists of steel core with friction lining. It engages and disengages with mating steel plates by hydraulic force to control power transfer and gear shifting, suitable for frequent start-stop and heavy-load loader working conditions. Excessive lining wear, heat burn, warpage and spline damage will lead to clutch slip, power loss, delayed shift and abnormal oil temperature, and even complete clutch failure.

Part No.:9N-4331
Type: Wet clutch friction disc
Material: Steel core with friction composite lining
Matching Equipment: 980F, 980G wheel loader

Application Scenarios

Fits Caterpillar 980F, 980G wheel loader, for overhaul of transmission wet clutch assembly.

FAQ 

Q：Can I replace only one worn disc while others are intact?
A：Not recommended. Thickness mismatch causes uneven load, slip and accelerated wear.

Q：Can slightly blackened disc be reused after grinding?
A：Not recommended. Heat reduces friction coefficient and slip risk rises under heavy load.

Q：Will new clutch discs work if transmission oil contains metal debris?
A：No. Debris scratches disc and steel plates, flush circuit and replace oil fully.

Q：What risk exists if spline has minor burrs?
A：Disc binding causes uneven clutch action, harsh shift impact and local fast wear.
