[2] SHUTTLE CLUTCH
Clearance between Internal Snap Ring and Pressure Plate
1. Measure the clearance between internal snap ring and pressure
plate with a feeler gauge while applying the specified force.
Specified force : 177 to 294 N (18.0 to 30.0 kgf, 39.7 to 66.1 lbf).
2. Three points are measured, and the smallest value is assumed
to be clearance.
3. If the clearance exceeds the allowable limit, measure the
thickness of clutch disc and steel plate with vernier calipers.
4. If the thickness is less than the allowable limit, replace them.
5. Remeasure to confirm the correct clearance.
NOTE
■
• Clearance between internal snap ring and pressure plate is
adjusted by two kinds of clutch discs with different
thickness. Therefore, use the one of the same thickness
when you change clutch disc.
(Reference)
• There are two kinds of thickness of clutch discs.
• Thickness of plate, disc and piston.
