AIR pump – can I borrow/buy

(1/7) > >>

Stingraynut:
I am getting my AIR pump gutted – replacing vanes, bearings and drum with new bearings and shaft. My 88 vette is my daily driver and living in Cairns means there’ll be a delivery delay both ways as well as the time for the engineering work, to be done in Brisbane.

Has anyone got an 87-91 AIR pump I could borrow for 2 weeks ? Or one I can buy and get sent to the engineering workshop ?

If you read this and know someone who has a spare, please pass this on – I’d like to get this job done, my pump is getting very noisy.

Thanks

S’nut

Brutus:
I have the one I removed from my 77, but how similar it is to your late model one I have no idea.

Quickvette:
Why don't you bypass the airpump alltogether and gain some more horsepower

Stingraynut:
I am removing the drum etc from inside so it will be a freewheeling pulley but if I remove it completely I’m not sure if I can get a serpentine belt to fit the shorter distance and haven’t checked how it will affect the angles to the other pulleys.

If you’ve done this, please tell me everything, I’m planning to send the pump away on Monday 8th September

Thanks Brutus, I don’t know how similar the 77 would be and if it would fit – it doesn’t have to connect up to anything – just hold up the serpentine belt for a week.

Brutus:
All the Corvette parts places in the US  make a pulley replacement for the AIR pump on later models and from what I've seen of it, it can't be all that difficult to come up with your own version. I tried seaching for a pic for you, but came up empty sorry.
