Examination
Check the sheet for burnt areas, local discoloration indicative of overheating, and oiling. Replace disk if necessary.
Check the degree of wear of the friction linings.
- Maximum allowable lining thickness (over rivet heads) - 0.3 mm
Check the free play of the disc on the splines and the axial runout of the working surface of the pads.
Maximum disc free play (along the outer edge), mm:
- Model 180 - 0.7
- Models 190 and 200 - 0.8
- Model 215 - 0.9
- Maximum runout, mm - 1.0
Distance from hub center to runout measurement point, mm:
- Model 180 - 85
- Model 190 - 90
- Model 200 - 95
- Model 215 - 102.5
Installation
Apply the recommended grease to the transmission input shaft splines.
Excessive amount of lubricant can damage the friction linings of the driven disc.
