What happens when a smog pump freezes?, 1976 2.0 Options

[burton73]

I live in CA. and it's time for my Registration so I went to the local smog station today and the guy pointed out that my pump was frozen. He took no money from me but said if I did not fix it I would not only pass the test but also screw up my EGR valve or something he pointing to down the line from the pump.

I stopped by the shop next door and my buddy looked at the pump and the lower pulley with mirror and said the bottom shaft had pulled out from a sleeve or something like that.

I thought some one could help me out on this. Can the bottom pulley be fixed with the Engine in the car? Does the sheath need to be replaced after the car is run for some time with a frozen pump and will it screw up the car to run it with the pump frozen like it is?

The smog guy thinks that when the next 2 years are up the 76 will not be on the same list anymore. I think when I bought this one 2 years ago we thought the same thing.

Thanks,

Bob

I have a rebuilder on-site that does water pumps and smog pumps (Riverside, CA). PM me if you need help.

A frozen pump can be the bearing failed and you hope the guts didn't wobble and gall the inside of the housing.

What it might screw up or it's already screwed up is the check valve (prevents exhaust gasses from entering the pump. It should be replaced when you change the pump anyway.
