1. Use a soft wire and compressed air to clean orifices. Replace if condition is questionable.
 

IMPORTANT: A piston cooling orifice failure could  cause damage to pistons, piston pins, rod pin
bushings, and liners. If a piston cooling orifice  is left out, low or no oil pressure will result.
 

IMPORTANT: The 9 L engine has directed oil piston  cooling. Be certain orifice is installed in
proper orientation to liner bore.
2. Locate JDG1948 piston cooling orifice installation tool  (A) in main bearing diameter.
 

3. Coat 12 mm (1/2 in.) of piston cooling orifice with
LOCTITE® Threadlocker medium strength 242 (Blue), as shown.
 

NOTE: Installation tool and cooling orifice have matching surfaces to properly align orifice in
block. If surfaces are not aligned, the installation  screw can not be started.
 

4. Install piston cooling orifice (B) in block from liner  side, as shown. When tool and orifice are in proper alignment, the installation screw (C) will be in an up  position.
5. Assemble installation screw into cooling orifice with  fingers. This will begin to seat cooling orifice in block.
6. Tighten installation screw to specification to seat  orifice in block.
 

Specification
Piston Cooling Orifice into
Cylinder Block—Torque................................... 15—17 N·m (11—13 lb-ft)
 

7. Verify installation depth by removing screw (C) from installation tool. Reassemble screw loosely in
installation tool. The ring on the screw shank (D) should be even with or above top surface of tool.
