INSPECTION OF HYDRAULIC MULTIPLATE
CLUTCH
INSPECT DISCS, PLATES AND FLANGE
Check if the sliding surfaces of discs, plates and flange
are worn or burnt. If necessary, replace them.
HINT:

If the lining of the disc is exfoliated or discolored,
or even a part of the printed number is defaced,
replace all discs.

Before assembling new discs, soak them in ATF
for at least fifteen minutes.
