AC Compressor discectomy
 

From the previous owner the ac compressor bearing was seized and broke the pulley so I decided to pull the compressor to install a new bearing and pulley but decided to open it up to make sure it was clean.

Clean it was but I stretched the o-ring on the back of the housing and can’t find a matching size, anyone know where to look?

Its ID is 116.5mm and OD is 123mm

Also check out how it looks on the inside. Looks a revolver haha

Cool engineering. Ive never taken one apart.

So I found this gasket and thanks to the much appreciated help from the seller, I believe this will fit the BMW compressor:

Obviously just the O-rings.

So a kit for a pre '92, 5 cyl GM compressor will work with a 7 cyl BMW unit?
:popcorn:

I'll let you know once it arrives.

The gasket (o-ring) fit the compressor perfectly, as if it was designed for it.

Put the compressor back together and will be installing it back in the car later this week!

Looks like an old torpedo motor (Duke engine).
