Clearance between Internal Circlip and Belleville Washer
(Cupped Spring Washer)
1. Measure the clearance between internal circlip and belleville
washer (cupped spring washer) with a feeler gauge while
applying specified force.
Specified force : 176 to 296 N (18 to 30 kgf, 39.6 to 66.1 lbf)
2. 3-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 circlip and belleville washer
(cupped spring washer) is adjusted by two kinds of clutch
discs with different thickness. Therefore, use the one of the
same thickness when you change clutch disc.
