Installation Tips
When replacing friction plates in your workshop:
- Drain hydraulic oil before opening the clutch housing
- Remove and inspect all plates in the stack, not just the visibly worn ones
- Check steel separator plates for scoring and heat discoloration – replace if damaged
- Inspect the piston seal – a leaking seal causes low engagement pressure
- Clean housing thoroughly before reassembly
- Follow manufacturer torque specs for piston housing bolts
- Bleed air from the system after refilling oil
Always replace the full set of friction plates together. Mixing new and worn plates causes uneven pressure and accelerated wear.
