Old Man Emu Leaf Spring Width?

Can someone measure their springs, I'm at work now and I want to order new sleeves and bushings.

I thought they were 2 1/2 wide but I put a ruler on the spring eye end before leaving the house and they measred at 2 5/16. Was I in a hurry? Did I not see straight? Or, is that right?

YJ, heavy duty version of OME leaf springs.

Thanks for a hand with this.

Just a guess, but I would bet they are a little skinnier at the spring eye to allow room for the bushing between the spring and the shackle/frame mount.

makes sense and that may be why the 2 1/2 sleeves I have now are too long.

I've got OME springs too and the bushings I bought stick out a touch too. Not a big deal.

what has been happening is the metal sleeves are a little too long and there is some side to side movement; like the plates are not perpendicular.


like this, / \ rather than this | |


I guess I could cut the tubes.

thx

the shackle plates should be about 3" apart. the difference between the spring-eye width and the plates should be taken up by the bushing which has a lip and should stick out about 1/4" on either side. the metal sleeve should be a hair longer then the assembled bushing. when tightened it should become one with bolt and shackle and the movement should take place between the bushing and sleeve. this is why they should be tightened completely and shouldnt effect "flex" contrary to popular belief.

right. the sleeves are tight to the plate but there is a little room between the plates and the bushings.

now that I have measured it, and assuming I saw it correctly, I probably have sleeves that are just a little too long for my springs.

I've got a pretty good mental image of what you guys are describing, and it seems like those metal sleeves should be cut down in jbolty's case...

I wonder how much should be shaved off? How much sleeve should extend past the assembled bushings and springs? Is 1/32" on each side about right? I'm just guessing to try and help stir the pot... Keep us informed on how it turns out

What fratis is saying is correct. You don't want the bushings themselves to mushroom out (or in, in this case). My BDS bushing sleeves were just a 'hair' longer than the bushings. Maybe 1/16th longer on each side. These were factory, so I can only assume they are correct.

I Jboltys case, if he can squeeze the bushing in and get them very snug in the spring eyes, then check the length of the sleeves, he could trim them accordingly if in fact they are too long and need to be trimmed.

Have been running a set of brandonyj booms with the OME bushings and with a set of greaseable bolts and sleeves I got from jc whitney. The whole set up is not lined up correctly and is binding.

I ordered a full set of greaseables from M.O.R.E. yesterday. When I get those I'll take some careful measurements and see if I need to trim the spring eye sleeve tubes. After measureing again last night the spring eye end is definately a little narrower than the middle and is a little less than 2 1/2"


as mentioned above, if the tubes are the exact right length you should be able to torque down the shackle bolts pretty hard without effecting the movement, since the tubes carry all the pressure.
