CJ PS bracket woes

This is somewhat embarrassing...I cannot figure out how to adjust the PS pump to tighten or loosen the belt. Before you laugh, I've loosened every bolt in there and I cannot get it to rotate at all. I know the PO has had a later model 258 dropped in and I think this may be the problem. The CJ is a 78 and the engine is probably an 84. I do not believe that the correct brackets were used to mount the PS pump. I have attached a pic of the bracket on the manifold. On the pic the arrow points to the part of the pump that I believe should rotate. To the left of the arrow, you can see the lip that is causing my problem. It appears that this lip by the manifold is preventing the pump from rotating when the bolts are loose. If I remember correctly, on other CJ's, this plate on the manifold is flat with no lip. Am I crazy or what? I'm tempted to take it all apart and just cut that lip off or start looking for another bracket. Any input is appreciated.

Re: CJ PS bracket woes

Looks like the PS bracket on my 83. There is another bolt that you can't see that needs to be losened on the back side of the pump. It's about 4 inches toward the fendor and down a couple of inches from your "mark". You have to "feel" for it.

Re: CJ PS bracket woes

Are you talking about the bolt that the pump pivots on? I got that one too. I've had every bolt so loose that I could move the pump side to side by a 1/4". I'll take another look.
I looked at another CJ this AM and his back plate was flat without that 1/2" lip and his pump was able to rotate toward the fender more.

Re: CJ PS bracket woes

I have ps brackets from both an 80 (cast iron intake) and 84 (aluminum intake). You have the stamped steel bracket made for an 84 with the aluminum intake. That curved section is necessary to clear the exhaust manifold that goes with an aluminum intake. The other one will not fit. Yes it is flat there, but it won't clear the exhaust manifold. I tried it a couple of month ago when swapping intakes. So if you have an aluminum intake, it's not a problem with the steel bracket that bolts to the block.

I've used my 84 pump and aluminum bracket on both an 80 and 84 and it fits. But does it work the other way too??

Re: CJ PS bracket woes

Tim,
So there are two brackets. Good. I thought there might be.

Am I correct in assuming if I cut that lip off, that I would be able to get more tension on the belt because the pump would be able to swing higher? Or do I need to look for the correct pumb/bracket combo for the manifold?

Re: CJ PS bracket woes

It looks like your aluminum bracket is making contact with that lip?

Mine has clearance between the end of the cast aluminum and that lip, so it's of no consequence.

I'd take the belt off, loosen all the bolts and really take a good look at that setup. Maybe even remove the front plate and see what's going on there. Is the belt you are using too long possibly? Even if it does strike the lip, shouldn't it move in the other direction?

Re: CJ PS bracket woes

You are missing the (top) long bolt that goes up top thru the triangular plate and into the flat surface on the intake manifold.

Re: CJ PS bracket woes *Solved*

Problem Solved.
I finally got ahold of a friends 86CJ and discovered that not only is the mounting plate with the lip for the aluminum manifold different from the ealry model CJ's, but the bracket the pump sits in is different as well. It's notched to accomodate the lip of the plate. Just an FYI is you are mixing and matching from different years of CJ's.
