- This slipper clutch is designed for using STD clutch plates. It is necessary to install the plates in a different
order. NEVER install the friction plate with bigger inside diameter and
steel rings as first. First install a normal friction plate ( f ) , then a
steel plate ( g ), and then the friction plate with bigger inside
diameter with steel rings – straight
, then a steel one ( h, i ) . The remaining plates mount as normal ( j
).

spring kit-retainers , tighten all bolts
Check for the correct
clearance between the pressure plate and
clutch hub via the small holes in
the pressure plate. Correct clearance is about. 1.5 mm. Minimal clearance is
0.5mm, when clutch plate wear causes it to be smaller, change all friction
plates
