Make sure that the pump is clean, and then put a straight-edge across the face of it. Use a feeler gauge to check the clearance between the straight-edge and the vanes and rotor. The gap should be no more than .005 in.gaco oil seals latest technology.
Turn the pump shaft until the locating ring has moved to the outermost edge of one of the vanes. Measure the gap at this point, between the vane and the pump body It should be no more than .005 in. (.13 mm).
Checking the oil pump
Without moving the locating ring, measure the gap between the opposite vane and the pump body. It should be no more than ?010 in. (.25 mm).
Check the clearance of each vane in its locating groove. The clearance should be no more than .005 in. (.13 mm).
Clearances on a multi-lobe rotor-type pump
centre an inner rotor lobe on an outer rotor lobe and measure the gap between them. Repeat with the other lobes.

Turn the drive gear until the tips of an inner and an outer lobe are opposite to each other. The clearance here usually should not be more than .010 in. (.25 mm).
Put the feeler gauge between the outer rotor and the pump body. The clearance here should generally be no more than .010 in. (.25 mm).
Make sure that the face of the pump is clean, and put a straightedge across the pump body. The gap between the straight-edge and the rotor surface should generally be no more than .005 in. (-13 mm).gaco oil seals latest technology.
