Usage:
Start By:
a. remove oil pump
1. Turn the crankshaft until pistons are clear of the cooling tube to be removed.
2. Remove bolt (1) that holds the piston cooling tube. Remove the piston cooling tube.
Install Piston Cooling Tubes
NOTE: If the piston cooling jets are to be reused, check the alignment of the piston cooling jet tube with Tool (A). See Special Instructions, Form No. SMHS7267, for instructions on the use of the piston cooling jet alignment tool group.
1. Put the cooling tube in position on the cylinder block and install the bolt that holds the cooling tube to the block.
2. Tighten the bolt to a torque of 25 ± 7 N·m (18 ± 5 lb ft) (3408 Engine). Tighten the screw to a torque of 25 ± 7 N·m (18 ± 5 lb ft) (3412 Engine).
3. With the piston at the bottom of the bore, check the clearance between piston and cooling tube 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 cooling tubes must fit evenly against the cylinder block. If they do not, it will cause an oil loss in the engine oil system.
