Specification for 391-1392 Piston Cooling Jet Gp    
Item     Qty     Part     Specification Description    
-     -     -     The piston cooling jet must be checked for the location of the stream of oil. Insert a drill rod with a diameter of
2.0 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
5.6 mm (0.22 inch) at point (1).    
-     -     -     Use the following dimensions in order to locate point (1) :
Dimension (A) is
27.80 ± 0.25 mm (1.094 ± 0.010 inch).
Dimension (B) is
21.51 ± 0.25 mm (0.847 ± 0.010 inch).
Dimension (C) is
250.00 ± 0.25 mm (9.843 ± 0.010 inch).
Dimension (D) is
250.00 ± 0.25 mm (9.843 ± 0.010 inch).
