Will a power steering pump from a C320 fit a C32?

The reason I ask is that my C32 ps pump seized, and I'm looking at replacing. Some of the pictures that I've been looking at show the C320 ps pump with a different pulley and I'm worried that the pulley will not line up correctly, does anybody have any experience with this? Thanks

It will not work mainly because of the pulley. See if the old one can be re-build. Also user search. There should be older threads regarding the C32 PS pumps.

ps rebuild

I read the posts on rebuilding and disassembled mine last night, the sleeve that the ps shaft passes through has been gouged and keeps the shaft from turning smoothly. So that option is out. I also read that the ps part numbers were the same for c32 and c320 but then I've heard they are different, so thanks for the clarification.

The pumps are not interchangeable. The C320 uses a pressed on 6-rib pulley and the C32 uses a bolted on 8-rib.

I'm thinking the pulley is the only difference. I removed the front half of the old busted ps pump per one of the DIY on this website, rebuilding is fairly straight forward. rebuild kit is under 20 bucks. I'm wondering if just the face of the pulley shaft is the only difference. I'm thinking I can take the current pulley shaft I have and use it on a C320 pump. I think the pumps are the same except for where the mounting of the pulley itself is concerned, and of course the pulley is different. Just a thought.

They are completely different. Only thing the same between them is the reservoir.
