1. Apply compressed air to each piston cooling jet valve at (A) and verify that air passes through piston cooing
jet valve at (B). if air dose not pass replace piston cooling jet valve.
Air pressure : 24.2~32.7psi (166.8~225.6kpa, 1.7~2.3kg/cm²) maximum
2. Check piston cooling jet nozzle for clogs. Replace nozzle if necessary.
Piston
Replacing a piston also requires replacing piston ring.
1. Check circumference of damage, scoring, or unsual wear patterns. Replace piston as needed.
2. Check outside diameter of each piston at a 90° right angle to piston pin, 0.846in (21.5mm) below oil ring
land's lower edge.
Piston diameter

If piston is collapsed or ball mouthed, replace piston.
