Usage:
Start By:
a. remove oil pump
1. Turn the crankshaft until pistons are clear of the piston cooling jets to be removed.
2. Remove screw (1) that holds the piston cooling jets. Remove the piston cooling jets.
Install Piston Cooling Jets
NOTE: If the piston cooling jets are to be reused, check the alignment of the piston cooling jet with tooling (A). See Special Instructions, Form No. SMHS7267, for instructions on the use of the piston cooling jet alignment tool group.
1. Position the piston cooling jet on the cylinder block, and install the screw that holds the cooling jet to the block.
2. Tighten the screw to a torque of 24 ± 7 Nm (18 ± 5 lb ft).
3. With the piston at the bottom of the bore, check the clearance between piston and piston cooling jet with a piece of wire (1) 0.63 mm (.025 in) thick. If the clearance is less than 0.63 mm (.025 in), make a replacement of the tube.
NOTE: The piston cooling jets must fit evenly against the cylinder block. If the piston cooling jets do not, this misalignment will cause an oil loss in the engine oil system.
