Tighten drive gear-to-shaft nut (4) to 45 ft-lbs (60 Nm). Install access cover plate using a new gasket.
First, pivot pump housing away from cylinder block as far as slots will allow. Then, pivot it back again, but only
far enough to align timing mark on the pump flange exactly with timing mark on the cylinder block front plate.
This is to take up any possible gear backlash.
