Procedure

1. 1. Nozzle Spray Path (S/N: 0460813072 & higher) 05 TS-55Rev2 - 2 - August 7, 2006 REQUIRED ACTION NEVER comes into contact with ANY part of the piston (skirt, underside of the dome, etc.). When servicing spray nozzles, pistons, or any component within the engine where accidental rotation, inspect spray nozzles for interference (see the repair procedure below). Be especially careful of contact with the underside of the dome, since this contact may be difficult to feel while rotating the crankshaft. If needed, use two people for this process; one person can rotate the crankshaft while the other one inspects the pistons and nozzles. Remember that the nozzle should NEVER contact ANY portion of the piston. NEVER mix different styles of pistons in the same engine. The weights of the pistons are different, and if mixed in an engine can cause an imbalance. • When installing nozzles:
2. 1. Align guide pin on nozzle to the hole in the crankcase.
3. 2. Hand tighten mounting bolt.
