My smog pump seized up on me this weekend. In a quick fix i completely gutted it as I was 200 miles from home. I was think "I don't use the crap anyways so whatever." Now it doesn't completely stop the pulley but it is still hanging up on something, though there is nothing in there to hang up on. Any suggestions of what is causing this?

Matt:

Most likely the bearings in the pump have frozen. You can tear the
pump down and remove the crud and broken fins and see if you can
get some bearings to replace the old ones if you are just going to
use it as a pulley, or buy a dedicated pulley from SOR.

I think I may have to try the SOR pulley, when I had it off the bearing housing was contacting with the housing. I decided it was just part of the pump to keep a solid vacuum. I will look into SOR and see what is up with that.:cheers:
 
2 ideas. The is a member on here that sells the same pulley for half the price $100. I thinks is Jim something. Second idea is to replace it with a second alt. You can get one of those for a little more than an hundred and actually get something extra for your money.
 
Matt,

The comment "gutted it to get home" implies you pulled everything out, but one caveat... the one way valve on the air injection rail will fail, letting corrosive exhaust gases back into the rest of the system without air flowing.... so if emissions are intact, and everything was functional, you really should rebuild the pump and keep the air moving through the system.

Does Toyota sell a "rebuild kit". Just looked on SOR, didn't see any rebuild kits (I've bought them years ago). Bearings are pretty common sizing.

The $OR pulley - smog pump eliminator - runs $220. If you buy one, I want to see it! :)

Uh, you realize we have a few more years before the 'magic 24 years old for smog exempt' happens.... :)

I don't have the air rail hooked up, basically the pump was just pushing the air around my engine compartment. For near the same price I could get a new pump from SOR and hook it all up. I've been considering another alternator, however Im just a jobless high school kid so money is essential here.

Yup, that is who I was referring to, his name is Jim Chenoweth, and his handle is FJ40Jim. I would email or call him as he seems to be to busy to check PMs on a frequent basis. He is also the guy commonly referred to as the Carb Guru.

That is why I suggested the second alt. It is less than pulley or a new pump. It bolts up to the existing bracket, and you improve your vehicle. I posted a thread with all the details if you search through my past post. $165 is what I spent. Later you can ad a second battery if you want.

I always thought you need some special bracket to do that, maybe thats the F Im thinking off. Im planning on moving to corpus where smog isn't an issue so that is starting to seem like a real possibility.
 
Whatever you do stay away from SOR. They are a rip off across the board :eek:. Good luck with the project.
