Smog pump rebuild

[desmocruiser]

I see a few threads that list the needed bearings, is there a source for the vanes or a complete rebuild kit available?

My Personal " Official " ORACLE on this Topic is @Spike Strip , he will have all the facts you are looking for

No kit. Vanes unobtainium. One of the bearings, the one at the end of the shaft that fits into the pump housing, is proprietary for that pump and I have not been able to source it. Maybe somebody in the bearing biz might be able to. Part #s are listed in other threads.

Thanks! I don't need it for smog testing.

Has anyone tried to run without the Vanes on a truck with the rest of the smog eguipment without issues?

 

[Spike Strip]

Rather than ruining a valuable piece of unobtainium smog equipment that someone might need, why not just get a pump replacement pulley? FJ40jim sells one.

Good idea, I wasn't 100% certain I could without doing a complete desmog.

You can leave everything else intact. Air Injection sys will just not function. You can disable the other systems with BBs in the various vacuum lines.

If you have to go thru emissions and can meet the requirements with a dummy pump would be a reason. California may have moved up 1976 but AZ is back at 1967 and newer in areas requiring emissions. Missing a air pump on the visual inspection is a automatic fail.

someone posted in the 60 tech section about a place that rebuilt them, he had 1 or 2 of them done. maybe last spring?

That was me: BZ Rebuilders in Canoga Park. They do SORs rebuilds. They sell on eBay.

I wrote this a few years back:

Smog Pump Rebuild - Land Cruiser Tech from IH8MUD.com

1971 FJ40 Wiring Diagrams - Land Cruiser Tech from IH8MUD.com

I was able to find all the bearings I needed:

Front bearing 6203-2RS (Qty 1)
Rear bearing B188 (Qty 1)
Vane bearings BA65 (Qty 4)

I also found reference to these guys for rebuilds - no experience with them:

Pacific Exchange Rebuilders

Pacific exchange is now BZ.

Also, the end bearing for 79-87 is different than earlier pumps

I disagree with this statement Alf. I would remove and cap the air injection system at the very least.

The tubing on the air rail is comparatively thin. It relies on having the relatively cool air from the pump going through it to help keep its integrity. Without the pump, it is subjected to pure exhaust heat, which will hasten its demise.

Agree about the bbs in the vacuum lines. And about getting a pulley from @FJ40Jim .

Have one rebuilt by BZ. 210.00 and quick turn around.

If you want a nice, clean OEM solution to plug the air injection ports in the cylinder head fork over some big bucks and buy six of these:

90340-14001 - retail $10.63 each, but $7.60 each at www.toyotapartsdeal.com

They're used in the 3FE cylinder head to block off the two unused ports (the 3FE air rail only has four ports). I made my own for my '76 FJ40 by cutting off the ends of six metric bolts and cutting a screwdriver slot with a cut-off wheel in my Dremel tool.

And you might check with @FJ40Jim to see if he sells air injection port plugs.
