Grainger 3X586 & 3X573 don't work

[John Smith]

Update 2016! They work just fine if you have the correct PS pump, which I did not. Use Cardone #20-6801 with a non-keyed 3/4" shaft or other similar pump.

Based on the Grainger part numbers 3X586 & 3X573 found in no fewer than 10 threads I ordered the pulley and bushing for my Saginaw PS pump. These parts won't work with a PS pump unless it has a 3/4" shaft. I should have looked at the bushing specs before I blindly ordered and it would have been obvious this was not going to fit. Hopefully this will save someone else the hassle of a parts return in the future.

have you checked with page 992 on McMaster Carr? they have the taper lock bushings to use on the inner part of your pulley...what size pulley did you get?

I have not checked McMaster yet. I will check that out now. I don't see a bushing in the Grainger catalog that will work with the 3X586 pulley and a Sag pump.

I recently spent a lot of time doing this same research. There is a bushing, 3x572, that will work for the keyed 5/8 shaft, but you have to cut it down to get the nut on the end of the shaft. I was still uncertain whether I could trim it enough to adequately enage the nut.

The other issue is pully alignment. This solution is specific to wdorry's ps pump bracket. It "may" not work with a MAF, SOR or JTO bracket, dpending on what drive pulley you are trying to use. IPOR specifically told me that their bracket and pulley are designed as a matching set also, so it probably won't work with thier's either.

Since I have the MAF,SOR,JTO design bracket, my only choice was the MAF pulley.

Hope this helps...

EDIT: As shown in pics below, the bushing/pulley setup can work with the MAF,SOR,JTO bracket in some configurations.

Pulley

#1 You should use a pump with the press on pulley
#2 You can get a bushing for that pulley in almost any size 5/8- 1 1/8
#3 If you have a pump shaft that required a nut you don't need to use the nut with a taper lock just the key.It will not come loose
#4 I can't belive that this pulley won't work with other setups as long as the pump shaft is in line with the other pulleys.

X2.... exchange that pump for the correct one.......

#1 Got a application or part number? The pump I have is a 206000 from Parts America / AdvanceAuto. I was not aware Saginaw pumps used different shafts. Are the press on pulley shafts 3/4"?
#2 The problem is even with a 5/8 bushing, the bushing height won't allow you to get the nut on. See pjohnson's findings, I could not find a short height bushing anywhere either.
#3 I have a hard time believing this but have not worked with split taper bushings and pulleys before. It seems like it would need a nut to hold it on the shaft.
#4 You may be correct.

I will clarify. For my application, I needed the pulley to align with the inner drive pulley. The bushing/pulley set-up is not offset and my bracket would not adjust enough to get the alignment I needed.

Lance specifically said the IPOR pulley would not work with the MAF,SOR,JTO style braket. he said that he designed it for his bracket.

All the posts I read were unclear about pulley alignment with particular brackets.

Also, I would not trust the split taper bushing on the keyed shaft without the nut on the end.

pulley

#1 The pump you can get from rockauto.com , PN# 206823
#2 Again, you DO NOT need a nut with a taper lock pulley. There are 20 or 30 people on this site that have used the taper lock pulley. The only problem I could see is if the pump you have doesn't have a long enough shaft for the bushing. The press on pulley doesn't have a nut and the taper lock is tighter on the shaft then the press on.

Grainger pulley and bushing

I am going to be installing mine this weekend. The pump I bought does not have a keyed shaft OR a nut to hold the pulley. Just went into the local parts store and told them I wanted a PS pump for a 75 GMC truck, their only question was 1 bolt or 2 and I asked for the 2 bolt version. I'll be posting pics as soon as I figure out the smog pump issue. That's another story so won't hijack.

head mount style bracket

pics are from a 76 FJ55 using the head mounted style p/s pump bracket. Pump is an A1 cardone 20-6800 pulley's are the ones being discussed. OEM smog pump runs off the inner groove (smog, w/p, crank) and the p/s is run off outer groove (p/s, alt,crank).

wdorry mount

This set-up is on a 72 FJ40 using the wdorry mount, A1 Cardone 20-6800 pump and pulley's discussed. P/S, W/P and crank. Alt, W/P and crank.

Tim,
Thanks for posting these pics. It really helps to clarify the different brackets with the bushing/pulley setup and drive pulley alignment.

This would have saved me 3 weeks of research. I think the solution for me would have been the same though.

No problem!

Pulley

Looks like both brackets have taper lock pulley.

Old thread revival. I used @John Smith saginaw power steering install as my reference. I have run into an issue when installing the pulley and bushing on my saginaw pump (Cardone #20-6800). It appears I may have purchased the wrong power steering pump in the first place should be Cardone #20-6801.

I used the correct pulley installation tool but it pulled the shaft out of the pump. I was expecting the bushing to crimp down on the shaft and spin as one unit but now I have to order a rebuild kit or just order a new pump.

My question is where did I go wrong? I used the pulley and bushing listed on this page. However, the more I look at the pictures I see that my bushing is a split taper bushing and not a solid bushing like the ones pictured.

Any help is appreciated as I want to complete this swap asap.

Wow, I had forgotten about this thread. You got the wrong pump, as did I, when I posted this 9 years ago. You do want Cardone #20-6801 or any Saginaw pump with a non-keyed 3/4" shaft. You don't need to use any install tool when you have the correct pump, as it is not press fit. You will see when you have the correct pump. My Cardone #20-6801 is still going strong 9 years later.

Which pump is these one please? I did have a press on narrow pulley on it and had it removed yesterday.

Here is the Grainger pulley and bushing I bought the other day. Any help would be great Thanks
