1976 XJ-S V12 Water Pump and Air Pump: Can I rebuild them myself?
The water pump (EAC 2109 PA) from my 1976 XJ-S looks very good. The air pump (7801149) doesn't look to bad either. Can I rebuild either one myself? What tools would I need? Or should I ship them to a professional refurbishing company? Ideally I want exactly MY water pump and MY air pump back, not an exchange. Does anyone know a good shop that they have experience with?
I also found this broken off nut that looked like it fell out of the water pump. Any idea where it goes?

It has been sometime since l bothered to rebuild a Waterpump since new pumps are available at a very reasonable price.

As my pump had corroded badly inside and outside I bought a new one. Problem is, the earlier models supposedly had a slightly different pump... I think it was the pulley or so. Actually it was the pulley. Later models had a single grove pulley ...
Anyhow. Your pump is more related to those of the E-Type and you can source all parts for them nowadays. You can get the bearing, impeller, pulley and co still new. Overhauling isn't that hard anyway. You MIGHT have to press the bearing out... Some seem very stiff, others are held in place via a grub screw...
