REMOVAL CONTINUED
b. Turn jet (Figure 2, Item 1) 1/4 turn clockwise so that end of flange with capscrew hole is pointing up (1/4
turn is necessary to clear skirt of pistons that are at bottom of stroke).
CAUTION
Jet cooler tubes are set at a 92 degree angle so that oil is directed to a particular spot on
underside of piston. Careful handling of this assembly is extremely important. NEVER
remove a piston without first removing piston cooling jet. Failure to follow this caution may
result in damage to equipment.
c.
When cooling jet (Figure 2, Item 1) is properly positioned, pull cooling jet straight out, maintaining its
position. If cooling jet binds, use pry bars to pull it loose from crankcase.
d. Repeat procedure until cooling jet is removed from each cylinder from which a piston is to be removed.
