Air pump frozen up

Air pump frozen up
I purchased a 86 Jaguar XJ6 vdp about a month ago, and am working on a list of repairs. There is a component near the top of the engine on the drivers side that looks like an alternator, but from what I gather, it's actually an air-pump. The belt is not attached, and for good reason, as the pulley will not turn. Its completely frozen up.
The engine seems to run okay without it. Does anyone know exactly what this pump does, and if I am doing a dis-service to the engine by not having it replaced and hooked up?

As mentioned, you're OK without it.
As used on your car it really only served any purpose on a cold engine, pumping air into the exhaust ports. Although the pump is turning at all times a temperature controlled diverter valve dumps the pump output into the air filter cannister once a certain coolant temp was reached....157ºF, I think.
If you ever wanted to replace it any parts store can fix you up. It's the same pump was used on umpteen GM cars in the 70s-80s.

I removed my (working) pump about 2000 miles ago. It has absolutely no effect on the engine or performance. It de-clutters the engine bay quite a bit especially if you need to get to the AC compressor. If I had known it would be needed I would have saved it, however, it is now in a scrap yard in Jackson, Mi.
