Greetings fellow ZR1s from Down Under.
I currently have my ZR1 in the workshop looking somewhat forlorn.
The air conditioning compressor pulley bearing failed in spectacular fashion while cruising through my hood.
I felt a bit like Cheech and Chong, with the interior filled completely with white smoke that entered through the vents. Downed the windows to let it out only to find it coming out of the bonnet as well.
I chose not to stop and check it out for a few reasons, and nursed it home another 7 minutes away.
When I drove it in the workshop I lifted the bonnet to see smoke still pouring off the pulley.
Ok. The bearing collapsed which then ran metal to metal, melted the magnet coil (from which the smoke would have come from) and when I stopped, the pulley was so hot the serp belt melted in half and just popped off!
Anyway .... I pulled the manifold off took off the failed parts off the compressor and ordered replacements. While I was at it took the alternator off (brand new only 400ks ago) and regreased the needle roller bearing in the back of it (it was rumbling a bit). Pulled the tensioner off and will re-do the bearing on that too.
Soooo I checked the water pump and it is not leaking, has no noise when you spin it. But it does have a small amount of freeplay side to side.
My question is, has anyone elses pump had this very small sideplay? Should I just leave it alone or look at replacing the pump bearing?
What have you found in the way of movement in your pump shaft?
Cheers
Bruce.
