Item Qty Part Specification Description
Use compressed air in order to check the piston cooling jets for plugging.
Visually inspect the piston cooling jets for damage or distortion. If damage to a cooling jet is suspected, replace the piston cooling jet.
The proper operation of the piston cooling jet is essential to ensure correct cooling and lubrication of the piston. When you remove the piston cooling jets from the engine, be sure to handle the cooling jets in a manner that the jets will not become damaged.
- - - The piston cooling jet must be checked for the location of the stream of oil. Insert a drill rod with a diameter of 2 mm (0.08 inch) into the orifice. The drill rod simulates the stream of oil under normal operating pressure. The drill rod must pass through a circle with a diameter of 4.5 mm (0.18 inch) at point (F).
- - - Use the following dimensions in order to locate point (F):
Dimension (A) is 63.25 0.25 mm (2.490 0.010 inch).
Dimension (B) is 54.99 0.25 mm (2.165 0.010 inch).
