  Q: How to properly disassemble and reassemble a water pump on BMW 2002?

  A:

  Using a suitable two-legged puller, draw the pulley mounting flange from the water pump shaft, then extract the circlip and spacer ring which are now exposed. Support the water pump housing and apply pressure to the end of the shaft in the center of the impeller, which will push the shaft from the impeller and the shaft/bearing assembly from the water pump housing. Drive out the water pump seal and cover ring from the water pump housing and fit a new seal. To install the other components, press the shaft/bearing into the housing and then press the impeller onto the shaft using Loctite to secure it, ensuring there is a clearance between the face of the impeller and the housing of between 0.031 and 0.047 in (0.8 and 1.2 mm). Finally, press the flange onto the shaft so that the distance between the front face of the flange and the cylinder block mating face of the pump housing is between 2.957 and 2.973 in (75.1 and 75.5 mm).
