description

Plastic seal ring is a dynamic sealing part installed at transmission clutch. It fits rotating clutch structure, isolates transmission pressure oil, controls clutch oil pressure and reduces internal leakage to protect clutch friction plates and pressure plates. Wear, deformation, fracture and jamming of the seal ring will cause clutch slipping, weak shifting and unstable oil pressure, and accelerate friction plate burnout.

FAQ 

Q：Can I keep using it temporarily if the seal ring cracks?
A：Not recommended. Crack will cause rapid oil leakage and pressure drop, which may damage internal gears and bearings.

Q：Which direction should the split gap face during installation?
A：Keep the gap away from high-pressure oil impact, follow official assembly drawing, do not face oil inlet.

Q：Can ordinary O-ring replace this plastic seal ring?
A：No. They differ in structure, pressure resistance and wear resistance, replacement will lead to early failure.

Q：Why does the seal ring get crushed quickly after installation?
A：Excessive groove clearance, overpressure and insufficient chamfer /burrs on groove are the main causes.
