I have a 1938 water pump here for overhaul , I have a kit with bearing and seal , what I wish to know , is , where the thrust washer (behind the seal) runs against the pump housing , is that contact surface supposed to be very smooth ? It is pitted from rust and a bit grooved from wear .

Should I machine the face where the thrust washer contacts ?

Thanks Dave , that is a great set of pics . It clearly shows that I have the 2nd type for 1938. The shop manual overhaul only shows the 1st type details.

Update .

I machined the seal face a little , just to clean it up , best I could , used a Lada bearing and seal kit , had to hone the impeller and fan hub bores a few thou' (chev parts imperial Lada parts metric) and got it all back together. Seems ok smile
