1. Measure the clearance (A) at 2 points or more diagonally oppo-
site using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the mean value.
2. Measure the clearance (B) at 2 points or more diagonally oppo-
site using a feeler gauge. Then calculate the mean value.
3. Measure the clearance (C) at 2 points or more diagonally oppo-
site using a feeler gauge when pressing baulk ring toward clutch
gear taper cone. Then calculate the mean value.
BEARINGS
If the bearing does not rotate smoothly or the contact surface on ball
or race is damaged or peeled, replace with new ones.
