Notes

Check the CVTF level, and check the CVTF cooler lines for leakage and loose connections. If necessary, clean the CVTF cooler lines.

Notes

Calibrate the start clutch control system Testing and Inspection.

Notes

Check the drive and driven pulley pressure, and the lubrication pressure CVT Pressure Test. If the pressure is low or there is no pressure, check the CVTF pump, the CVTF pump chain, and the CVTF pump sprocket.

Notes

Check the forward clutch pressure CVT Pressure Test.

Notes

Inspect the clutch piston, the clutch piston check valve, and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the clutch end-plate and the top disc. If the clearance is out of tolerance, inspect the clutch discs and plates for wear and damage. If the discs and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the clutch end-plate.

Notes

Check the reverse brake pressure.

Notes

Inspect the reverse brake piston and the O-rings. Check the spring retainer for wear and damage. Inspect the clearance between the reverse brake end-plate and the top disc. If the clearance is out of tolerance, inspect the reverse brake discs and plates for wear and damage. If the discs and plates are worn or damaged, replace them as a set. If they are OK, adjust the clearance with the reverse brake end-plate.
