REPAIR INSTRUCTIONS, PART 1
Using piston cooling nozzle spray position set
J 39045, check the direction of the spray from the
nozzles. Refer to Figure 215.
1. Position rod in the end of the spray nozzle.
2. Place the applicable plastic target on the
cylinder block over the cylinder to be tested.
3. Install a cylinder head bolt through the target
alignment hole and into the cylinder block
capscrew hole.
4. The rod should now be aligned in the target
area. If the rod is at the edge of the target
area, center the rod in the target area as
follows:
a. Loosen the nozzle setscrew. A slight
adjustment can then be made to center
the rod within the target area.
b. Following adjustment, tighten the
setscrew to the specified torque,
15 lb-ft (20 N폷m).
Always replace a badly deformed spray nozzle.
Do not attempt to realign it. Precise targeting is
necessary to adequately cool the piston crown.
