Clearance between Hydraulic Arm Shaft and Bushing
1. Measure the hydraulic arm shaft O.D. with an outside
micrometer.
2. Measure the bushing I.D. with a cylinder gauge, and calculate the
clearance.
3. If the clearance exceeds the allowable limit, replace the bushing.
(When reassembling)
• When press-fitting a new bushing with a press-fitting tool (refer to
“8. SPECIAL TOOLS” at “G. GENERAL” section), observe the
dimensions described in the figure.
• When press-fitting a new bushing, apply transmission fluid to the
hydraulic cylinder liner boss and bushing.
• When press-fitting a new bushing, press-fit it so that each seam
faces up.
