Assembly
Check the fit of a new piston, pin and ring (6102) in the cylinder bore before assembling the piston pin
(6135) and piston, pin and ring to the connecting rod as outlined in
The piston pin bore of a connecting rod and the diameter of the piston pin must be within specification.
1. Check the ring side clearance of the compression rings with Feeler Gauge D81L-4201-A or
equivalent by inserting it between the ring and its lower land. The gauge should slide freely around
the entire ring circumference without binding. Any wear that occurs will form a step at the inner
portion of the lower land. If the lower lands have high steps, the piston should be replaced.
2. Apply a light coat of engine oil to all parts.
3. Assemble the piston, pin and ring to the connecting rod, putting the notch in the piston dome and the
connecting rod on the same side.
