  • Figure 3-12. Checking oil pump radial clearance.

    2012-6-19 · Too little clearance can result in binding between the rotors and cover plate when hot and the metal expands, where if the oil pump does not sieze, premature distributor/oil pump drive shaft failures may occur. Too much clearance will allow excess oil to leak by resulting in loss of oil pressure and volume.

  • Performance Oil Pump Blueprinting ::: CLEARANCING

    Low oil pressure - indicated on the oil-pressure gauge or dashboard warning light - could provide an indication of wear or damage to the pump. The oil pump is usually one of three types: the multi-lobe rotor type, the gear type, or the vane type. Whichever type of pump is fitted, it must be removed from the engine before it can be properly checked.
