•  Measure the distance (B) between the bearing race 

installation surface and the machined surface. 

•  Calculate the total end play using the following formula.

Total end play = distance (A) – distance (B) 

If the measured and calculated end play is outside the 

specified range, replace the existing bearing race with a

bearing race of the proper size (thickness). 

Total end play = 0.25~0.55 mm (0.0098~0.0217 in) 

Available oil pump bearing race thicknesses 

1.4 mm (0.055 in)
