FAQs

How many discs are in the TRW MCC505-6 kit?

This kit contains 6 individual clutch discs.

Do I need to soak these discs in oil?

Yes, it is best practice to soak the new friction discs in clean engine oil for at least 30 minutes prior to installation to ensure proper break-in.

What is the thickness of these discs?

These discs have a consistent thickness of 3 mm.

Will these fit my specific motorcycle?

Please verify your motorcycle's specific clutch requirements against the MCC505-6 dimensions (139-150 mm OD, 117 mm ID) provided in your service manual.

Should I replace the steel plates at the same time?

It is recommended to inspect your steel plates for signs of heat discoloration, warping, or scoring; if they are worn, they should be replaced alongside the friction discs for optimal performance.

Troubleshooting

Clutch feels like it is slipping under load

Check your clutch lever free-play or cable tension. If the adjustment is correct, verify that the clutch springs are not weakened or reaching their service limit.

Difficulty shifting gears

Ensure the clutch plates were properly soaked in oil before installation and check that the clutch basket fingers are not notched, preventing plates from sliding freely.

Setup, Compatibility & Care

Before starting the installation, ensure you have the correct service manual for your specific motorcycle model to verify torque specifications for the clutch cover and pressure plate springs.

  1. Soak the discs: It is highly recommended to soak the new friction plates in fresh engine oil for at least 30 minutes before installation to ensure immediate lubrication.
  2. Inspection: Inspect your clutch basket for "notching" or grooves. If the basket is worn, it will cause the new discs to hang up, regardless of their quality.
  3. Stacking: Follow the manufacturer's order of plates (friction vs. steel) exactly as noted in your manual.
  4. Maintenance: Regularly check your clutch cable tension or hydraulic fluid level, as proper actuation is key to preventing unnecessary wear on your new clutch kit.
