Smog pump rebuild bearings

[Pin_Head]

Someone asked earlier but didn't seem to get a response, but would this rebuild apply to an FJ60?

Why not just look at the bearing numbers when you take yours apart? If they are not the same, you can order the right ones.

The smog pump in my 78 FJ40 started making all kinds of noise. I looked for a rebuilt pump but was blown away by the outrageous prices I found. I decided to rebuild it myself. I found a link on the forum that listed bearings I needed. I spent two days just tracking the parts down. Some of the bearings part numbers listed on the old link have changed so I was unable to locate two of the bearings online. After a trip to a local bearing supply, I got all the correct part numbers. I found a single supplier online that carries all three bearings. I have listed the part numbers, quantity, price and links below. After cleaning up the pump and replacing the bearings, the pump runs like new for less that $30.
I hope this helps.

Thanks for posting this up. I need to rebuild my smog pump, so I ordered these parts today.

Did anyone ever figure out where to get the grease needed for these bearings?

There is one other aspect of these needle bearings that should influence your selection and I apologize for not looking at all the data. The J/SCE/B series drawn cup needle roller bearings have limiting speed (rpm) specifications. When I reviewed the bearing specifications, it became clear why Toyota used J/SCE series bearings. The B series bearings have a limit speed that is greatly reduced from the J/SCE series.

Limiting Speed in RPM
J-65 36,000
B-65 7,100
J-188 11,000
B-188 3,800

Based on some rough calculations (I measured the diameter of the crank and both smog pump pulleys with a tape measure in the vehicle (at night) at 6.25”, 5” (4 bolt) and 4.25” (3 bolt).

Circumference of/ratio of circumference
Crank 19.6”
3 Bolt 13.4”/1.5
4 Bolt 15.7"/1.25

This would give a rough RPM for the 3 & 4 bolt smog pumps at the following engine RPM.

RPM
Crank 3000 4000 5000
3 bolt 4500 6000 7500
4 bolt 3750 5000 6250


Given the RPM that a well running 2F can achieve, the use of a B-188 becomes problematic in that the limiting speed would clearly be exceeded by some on this forum. This excess speed would actually shorten the effective life of the B-188 bearing (by how much?). Maybe this is one of the reasons Toyota went to a larger diameter smog pump pulley in later build years. Given all the info, I'm going to build the units with the B series because I want the higher load range. I let you know how long they last.

Well, here is a follow-up to this post. After running 2.5 years in a strong running 2F that I'm not concerned about cruising at 70/75 on the freeway, the B-188 rear bearing finally started to make noise in Aug. 2010 (bearing failure). The B series bearings used on the vanes and the front bearing showed no adverse issues. The rear bearing was the only bearing changed and the pump was put back together and ready for use. While I was servicing the smog pump, I bought a rebuilt smog pump from RockAuto for temporary use. I've got to say that this rebuilt smog pump is heads and tails above the pumps I've seen from stores such as AutoZone, Pep Boys etc. It has run so well that I have not replaced it. I went through emission inspection in Oct. with no issues. If I were in need of a replacement smog pump and did not have the two pullers required to pull open a smog pump, I would give this replacement some serious thought. This smog pump was rebuilt by A-1 Cardone. Besides all new bearings, new carbon vanes are installed and high temperature grease is used in all bearings. As much as I enjoy rebuilding components, I cannot rebuild to the level that A-1 Cardone can. I do not know of any source for new carbon vanes and they are critical to the performance of the pump. Given what it cost for the tools, both off the shelf pullers and custom to remove and install the vane bearings and the cost of the 6 bearings, the $79.79 cost is more than acceptable for the quality I see in the unit I have installed. Heck, I’m giving some serious thought to buying another one to put on the shelf for when it may be needed as they do not last forever and emission testing is probably just going to get harder for older vehicles.

Thanks...great to hear. Is this a rebuilt OEM pump or is it completely aftermarket?

Did you get a pulley with yours?
I think I have one of these pumps sitting on my shelf, but it looks to take a different pulley than the one on the pump currently in my vehicle...

My '78 FJ40 uses a 3 bolt pulley and the pump came with the 3 bolt hub installed. I do not know of any rebuilt smog pumps that come with a pulley. You will probably need to buy a used one. There are a number of cruiser related businesses that have them. If I had been thinking a little quicker, I would have bought all the 3 & 4 bolt smog pump pulleys that Tim Hill had.

All I can say is that it looks like the factory smog pump. I'll look at it to see who made it as I just installed it so I could drive my 40 while I rebuilt the factory unit. At the time I wasn't really concerned about who made it originally.

One additional thought about the rear bearing failure. I had made a spacer to put the smog pump pulley in alignment with the front pulley groove on the crank and water pump. This was due to the fact that the 4 bolt smog pump pulley I used on the power steering pump could only align with the front pulley groove. I subsequently bought a press-on hub and dual water pump pulley set-up for the power steering pump to convert from the existing single groove power steering pulley. The dual groove power steering pulley now lets the smog pump pulley go back to its original location. I'm sure that the smog pump pulley being extended to the front groove contributed to the rear bearing failure due to the increased length of the torque arm putting additional force on the rear bearing with the same belt tension.

Hmm... If anyone has a 3 and 4 bolt pulley out there they would like to sell off, let me know!
