can you rebuild a smog pump, or do you have to buy new? anyone done this?

 

I don't knoe if you can rebuild it, but if your intrested mine is gona be removed soon (i hope)

 

thanks for the offer, but it might not be feasiable to send it all the way up here to Canada, just wondering if you can rebuild one, or where you can get a new one

 

You can rebuild them. I forget the size, but it has two bearings, one at each end of the housing, and if you replace them, typically that's all that's necessary. Usually air pumps such as these sieze up becasue the grease in the bearings dry out, or get squeezed out after 60-100K miles. Normal issues with bearings you can't regrease.

The other thing to consider, is for what they charge for a new one (go to rockauto.com and see how inexpensive they are), it's almost not worth it to DIY.

 

I paid 58 dollars for a rebuilt smog pump, 21,000 miles ago. BTW, it is still working good.
The pump failed on me during an engine change,the failure seemed very strange. I took the pump out, layed it on the garage floor and it was working OK, I could spin the pulley by hand and feel it puffing a little air. After a month, it was ready to go back on, I picked it up, and the pulley was seized. I may have bumped, dropped, or kicked it by accident, and it may have gotten some water in it also, but there wasn't any rust inside.

I took the seized pump apart to fix it, I can usually take things apart and get them back together, but that darn thing confounded me! It has centrifical vanes inside and I got them all screwed up and gave up, not to mention I busted a part of the case when I tried to get it apart.

Just remember to take the old one with you to the parts store, they will want the core.

 

I checked the parts store they had two different ones for my 87 302, one was 54.00 and the other 70.00,(rebuilt) I have to get the part # off of mine to match them up,the parts guy I always use, said he removed his off his 90 mustang, with no adverse effects, but I read several post about guys having problems from removing the air pump, any comments on pro's or con's on this one guys

 

I left my pump in place but I removed all the pluming and left the solinoids pluged in, the only thing it does is throw 2 codes in the KOER. I just pulled the codes this afternoon but can't remember what they are. (I hate having CRS )

 

well, you can, but why bother? they generally run <$50 to get one with a LLT warranty....
