AIR pump – can I borrow/buy
Stingraynut:
Here’s a diagram of the C4 belt route, from the GM Manual.
It looks like the belt from the Alt to the water pump will be too close to the P/S pump, but I’ll check that in the real world today. Maybe I can raise my Alt enough to keep it clear.

Bad News - I’ve checked on my engine and the diagram is essential to scale – there’s no way the belt can run from anywhere except where the Air Pump is.
I looked at shifting the Alt to where the AIR pump is, the AIR pump bracket is a different width to the Alt so that would be a problem but also the back of the Alt sticks out further than the pump, I think the rocker cover would be in the way by 5-15mm.
Oh well, it was worth a try. It would be a lot easier than constructing a bracket or re-designing the pump – I expect lots of people have been down this track already – hence the various brackets. I still think they look like bits of mechano and would rather have the casing of the pump sitting there….quietly.
So……has anyone got an 87-91 AIR pump I can borrow or buy ?
It doesn’t have to work, I can send it straight to JOH engineering, they’re going to rip out the drum and old bearings, weld in new front and backs, put in new bearings and a central shaft – all freewheeling.
There’s a guy on CF who’se name is ‘Caratemymoney’ – I’m starting to identify with that.
