Terrain Tamer Suspension install questions - which way forward

Mike:

Slip Plate is a brand name of a goopy Teflon paint.

It's actually a graphite based paint. It eventually will wear away, but in the mean time the effort is well worth it.

Darkman- did you end up with the military wraps at the frame or shackle mounts then?

Thank you, Brian...I stand corrected.

The wraps are at the frame end ...

So what's the deal with flipping the springs... just turning them around-reversing them?? I understand the pin will sit further out, but what about the wrap on the springs, they now face the wrong way, under compression they now push into the frame as opposed to out... Am i reading this right, and its just the way it goes??
Sorry for the bit of confusion...
Cheers!

hummm, the spring compresses and push on the shackll, the shackle now moves , if the actuall assembly on the frame is the same then the spring will still flex outward...

Hey Wayne its me Dan with the 60 from the island, working the rigs... Yeah i understand the whole shackle principle, a couple years of engineering in school helped me through that... haha... what about the wrap on the springs is what i'm wondering about, cause the mil. wrap in facing a specific direction for a reason and now we're reversing the whole thing... i guess the wrap is just a redundancy in design i guess...

For a bit more wheel base, take the springs apart, flip the second leaf around, drill a new hole for the center pin, and put it back together (with some slip plate!) This allows for a bit more wheel base, and keeps the military wrap at the spring hanger where it belongs.

Military wraps good. You don't want this happening at the shackle end (or at all, really).

Hey thanks "ridgerunner", that's exactly what i was looking for! I just wasn't convinced on flipping the whole pack backwards and having the military wrap in the wrong place, and having it facing a specific direction for a reason didn't sit well with me...
Cheers!

Yep front springs double wrap forward,rear spring double wrap to the rear.QUOTE]

Nope Im wrong.
Mine have the double wrap at the pin end. Too much beer on a dark night

I for one, am glad to hear your springs are installed correctly.

 

[darkman]

OK .... so I had a bit of a "helmet-fire" last Saturday evening ... it all made sense on Sunday morning when I looked at the spring on the other side of my rig.

The miltary wrap on the spring is mearly an insurance policy that if the main leaf were to break the wrap keeps the spring from disconnecting from the mount point. Many springs have a double miltary wrap to have this insurance at both ends of the spring. reversing the spring and putting the wrap at the shackle end does not make any difference the wrap still does its job and does not harm anything.

I would much rather move the wrap to the shackle side than drill a hole in the spring especially after it has already be tempered or whatever process was done to it.

cheers,

Michael

I've got a couple pairs of broken Old Man Emus to prove you wrong. (actually in the trash now or I'd snap a picture) You'll likely be fine as long as you leave the porch on your rigs but if you build a bumper that allows you to get a tire up to a big boulder or shelf and you force the tire into it, the axle will try to run under the truck. The main leaf will over arch and, because the second leaf has no wrap, it can't do anything to help until the main leaf is captured by the back boltwrap where it will bend and later break. It happened to me with annoying regularity.

 

[crushers]

curious, did you ever have that happen on regular leaf setups?
i know on my 82 when i hit a rock i snapped the leaf right in front of the military wrap...

 

[lowenbrau]

Never happened to me but I've seen it. There can be a lot of stress at this point and that's why you need two leafs working for you. This is especially true with a lift spring where the force is being transmitted through an arched leaf. Its one of the arguements for springovers (less arch) and shackle reversals but, as you know, both introduce other challenges.
