1976 BMW 2002 Oil Pump Parts Questions & Experts Answers

• Q: How to check clearances and make adjustments for the oil pump on 1976 BMW 2002?

  A: Unbolt and remove the cover from the oil pump, then unscrew and take out the plug from the oil pressure relief valve, extracting the plunger and spring. Using feeler blades, check the following clearances: between the outer rotor and pump housing, which should be from 0.0039 to 0.0059 in (0.1 to 0.15 mm); between the tips of the inner and outer rotors, which should be from 0.0047 to 0.0079 in (0.12 to 0.20 mm); and between the rotor face and the cover mating face of the pump housing, which should be from 0.0014 to 0.0043 in (0.036 to 0.109 mm). If these tolerances are exceeded, necessary adjustments should be made. If the drive flange needs to be removed, use a two-legged extractor and press on the new flange so that the distance between the outer faces of the flange and rotor is 1.681 in (42.7 mm).
