Smog Pump Disassembly and Rebuild. (1 Viewer)

[Randy88FJ62]

This is one of the advantages of having the air pump above the alternator on the 3FE configured motor. I guess that is why mine has lasted so long? No fluids or major contaminants leaking all over it.

Would be nice to dis-assemble and do a partial rebuild. I prefer doing my own work when possible.

Reviving this thread with a question, @Spike Strip

I am rebuilding my smog pump (1976 FJ40) and these springs (red arrows) fell out when I disassembled it. Where do they go? They don’t go behind the “keys” (blue arrows), do they?

I saw somewhere that they go against the carbon fins, but I don’t see where that would work.

@skhochay just did this....

They tension the carbons (you call them keys) against the fiber vanes.

Thank you. So just to be totally clear, do the springs go in front of or behind the “keys”? Put another way, do the “keys” rest directly against the carbon vanes and the springs keep them tight against the vanes? Sorta like this?

Thanks guys. Much appreciated.

Quick question (know this an old thread but hoping).
Trying to gut my smog pump.
Having a devil of a time prying open the back (where the hose connectors are).
Anyone have any tips?

Thanks

You'd be better off buying a smog-pump eliminator pulley (it will work better than a gutted smog pump with 40 -year-old bearings) and you could sell the pump as a core (hint, hint) to someone in a smog-State who needs it, for half the price of the eliminator ... No fun when the smog pump seizes when you're driving...

There are different vendors, but this is a good one and good price:

Unfortunately, I am in a smog state. I just can't have that pump seize up on a trip, but I need the appearance of having an active smog pump for emissions.
So yeah, the pulley would be great. Just a pain for me to remove it every two years, replace the SP, then back again.

Sooo much fun.

Understood. The front bearing is replaceable but the rear bearing is unobtanium, for me anyway... The back comes off as stated above with a little persuasion... There's a couple alignment dowels that are probably rusted. Use some penetrant and give it a day, or a little heat on the dowels.
It's a tight fit.

SORs rebuilder, in Canoga Park is very good, if you want to make the thing functional and reliable. They seem to have a supply of both bearings:

Is there a part number for the front bearing? Looking to gut mine and have it just be a pulley, but I'd like to replace the bearing while I'm in there.
87 FJ60 2F. My replacement smog pump (used from cruiserparts.net) just failed. So now I have TWO that don't work. Will try to have a gutted one, then send off 2nd to get rebuilt ...

P62042RSJ.
P6204RSJ will work, but use P62042RSJ. It's enclosed on both sides, whereas P6204RSJ is enclosed only on one.

Gawd, I love MUD! Thanks @pathstaken

No worries. Those alignment dowels took a two pound mallet and a punch for me to get rid of.
Also, if you don't already have it, buy yourself a tube of high temp grease. I coated the rear bearing with that before putting it all back together.
Mine runs like a charm.

Where'd you get the rear bearing? I thought those were unobtanium?

I didn't. Just coated it and prayed.

 

[Rusto]

Ha ha. That's my plan as well. Thanks.
Bearing to be picked up at Napa tomorrow. With any luck, I'll have the Silver Beast back on the road before the weekend.

Pulled the old pump out yesterday - w/o having to remove the power steering pump! It's a Saginaw pump with @orangefj45 's kit, so maybe that helped a bit, but that was a big win. Just had to take the alternator PS belt off. Picked up my bearing from Napa today, less than $9 out the door and looks to be a perfect fit. Picked up a new belt from Toyota this morning as well. Other one looked fine, but after all that squealing and smell, I thought I'd replace it.

My previous smog pump, that also failed because of a broken blade has been gutted. Should be putting it back together and maybe even getting it done tonight.

I can't wait to not have any of those damn blades in there, waiting to break, jam it up and leave me high and dry.

 

[pathstaken]

I always keep my other Smog Pump with me, along with replacement belts (and screws, and hoses, and...)
I can't afford to be stranded on a long trip.
It's a pain to carry it, but it's worth it.
Good luck!
