running clearance should be 0.074-0.147 in. (1.880-3.374 mm).

new, thicker plates (2) and discs (3).

If clutch running clearance still exceeds 0.147 in. (3.374 mm) after completing step 2, replace
backplate (6) with new, thicker backplate (6).
4.
If clutch running clearance is less than 0.074 in. (3.374 mm), replace backplate (6) with new,
thinner backplate (6).
