FRICTION PLATE, FRICTION DISC, AND SPRING
PLATE WEAR CHECK
1. For the purpose of determining wear, measure thickness
(A, B) of the friction surface and protrusion at several
places and find the difference between the two.
Limit: 0.1 mm
2. If the wear exceeds the limit, replace the part with a
new one.

AA"HYDRAULIC UNIT HOSE ASSEMBLY REMOVAL
1. Disconnect the hydraulic unit side pipe and hose.
2. Put down the differential support arm, remove the
hydraulic unit hose assembly.
HYDRAULIC UNIT DISPOSAL
Should the hydraulic unit be discarded, drill a hole in the
accumulator at the illustrated position beforehand in order
to release the inside gas.
Caution
(1) The hydraulic unit has its accumulator filled with a high
pressure gas. Never throw it into a fire. Also, never
attempt to disassemble, press, weld or melt it.
(2) When drilling a hole in the accumulator, be sure to
wear safety goggles since drill chips may blow out
together with the gas.
