1. Install the fork insert J 24086-310 into fixture J 24086-10 .
2. Lubricate the piston pin with clean engine oil.

Important: Ensure that the marks on the piston and connecting rod are aligned the same as when removed. If installing a new piston, ensure that the arrow on top faces towards the front of the engine. If no identification marks were made during disassembly, ensure that the flat area on the bottom of the piston pin skirt is aligned with the small dimple above the connecting rod crankshaft bearing bore.

3. Assemble the piston, connecting rod and adapter J 24086-6A and install onto fixture J 24086-10 .
