This clutch should be installed by an experienced mechanic.

1. Read these instructions with photos before you start. Make sure that the kit includes all parts .

3. Make sure that the original spacer and thick shim under clutch drum is in it´s position ( pic.a).
4. Make sure the steel balls are in their pockets. Use one or two clutch springs and upper retainers to hold both parts of the clutch drum together. Position of both drums´s parts is to be as delivered.
5. Install the clutch to gearbox shaft ( pic.b ).
6. The kit includes small parts for mounting. They are packed in position as how to mount them. Mount the shim at first (pic.c ), then the spider spring (pic.d ) and the nut (pic.e ). Nut torque moment 120 Nm, use glue Loctite No. 620 (red) to secure ( pic.f )
