turn the engine off so it will not seize.
• Check oil passages and oil pump for dam-
age or leakage.
• Start the engine after solving the prob-
lem(s) and recheck the oil pressure.
• Tighten the oil pressure check bolt.

count the number of turns. Record this num-
ber as the factory-set number of turns out.
• Turn in the pilot screw until it is lightly
seated.

number of turns.
