Smog pump adjusting bracket on OEM PS conversion (1 Viewer)

[largenfirm]

Looking at the SOR catalog, page 48, there are two smog brackets (item #4) illustrated for 8/80 to 8/87 FJ40's - one for power steering, one for manual steering.

When converting manual to OEM PS, is it necessary to replace the smog bracket? Is this a clearance issue with the PS pump bracket?

I don't yet have the PS pump bracket in hand, so this may all become obvious when it arrives...

Will these help?

Not sure what vintage...

Yup, that answers the question!

Thanks,

I used the one that came on the fj60 PS pump, but I did not use the adjusting bolt(for some reason), just the lock down bolt, use a prybar to adjust tension.

one of these(heck if I remember) is OEM fj60, the other is OEM fj40

I think this is the OEM fj40

I think you are right about the 40.

I believe the 60 bracket has the slot furthre away from the engine, so in the second pic, it would be the one on the left...

Minor correction:
In Pimp's side by side pump photo, the adj bracket on the left is for larger 81-87 air pump. The right bracket is for 79-80 2F w/ smaller air pump.

It is not a bodystyle (40,55,60) difference, rather a symptom of the tightening emissions noose.

Jim,

Do the later pumps push more air? Sig amount?

old pic......I couldnt remember which was which

but the 40 pump is off a 81(OK maybe an 80, so yes different emmsions if thats the case, and it very well might be), But 8/80+ 40/60 AFAIK has the exact same emmisions, I know my 82 fj40's are the same as my 86 fj60

(note, I better print this post with pic so I know which pump is which.....only took me less than a year to forget so far

TJ,
Yes, the 81-later pumps are bigger in both diameter and depth, so they displace more air per revolution. However, the pulley dia increases by 20-25mm, so the pump RPM is slowed down a little bit. Overall, later pumps move more air, but I don't know the exact percentage increase.

If somebody needed to know it would be simple to disassemble the 2 pumps side-by-side, calculate volumes and then calculate shaft RPM based on pulley sizes. Let us know what you find on that.

Jim,

As a side note: you can see the early vs late smog pumps in Pablocruise's pics. the upper engine pic has the later pump(4 bolts on the pulley) and the lower engine pic shows the early pump(pressed on pulley)
