Hi all, there has been discussions previously about resetting springs in dribs and drabs throughout other posts (i just searched it), but i'm going to try to get the info together in one place. From memory Peter James (i'm pretty sure it was him) had bad experiences with standard resetting practices and used a jig in a shop press to cold reset them (i couldn't seem to find this info). I think it would be good to have the standard specs of the springs and how best to reset them in one place so here are a couple of questions (this info may help people buy new springs etc too):
- Standard LT front springs are 10 x 8mm leafs with 2 x shocks on each corner?
- Standard LT rear springs are 11 x 8mm leafs with 2 x shocks on each corner?
- Standard XT front springs are ?? x 8mm leafs with 1 x shock on each corner?
- Standard XT rear springs are ?? x 8mm leafs with 1 x shocks on each corner? (some later ones had dual rear shocks)
- What is the standard unladen distance from the centre of the leaf to the bottom face of the chassis member (or distance between spring and aeon rubber stop face?) This may depend on the weight of everyones oka's so what is the standard 'bow' of an unattached spring pack then? (this may be a better question...)
- Any other info someone may need?
Cheers, alister

I reckon standard XT is
Front 10 x 8mm
Rear 7 x 8mm plus 4 x 10mm straight over stroke leaves at the bottom.
Second leaf in all cases has military wrap ends.
Cheers,
Peter

Thanks Peter.
Anyone with any idea of the spec of the 'bow' of the springs? Anyone recently had springs made up and had to specify the arc or eye-to-eye distance of the set spring?
cheers, alister

No, but here is a pic of a set that came off #196 in 2003 when it had 330,000km as a tour bus.

For what it is worth, a few years ago I spoke to someone who should know, about getting new springs made. I explained that they were fine, but were old and possibly prone to breakage. He said I was better off to keep the old springs because the metal they had to work with today was crap, and the old springs would probably last longer than new springs made with metal available at the time.

The ones in the pic above were replaced because the rears were "worn out".
With the rear springs, the end of each leaf had worn into the one above it by almost 1mm.
Fronts were not so bad.

Peter

When I took mine to Carrols to have them reset, they rejected and replaced most of the leaves front and back for the same reason

lol someone could use those springs Pete and they're just rusting away in your back yard! I take it you got a full set made up when you did the gvm upgrade with helper coils on the rear?
I'm really just trying to get standard info together here in one place for people... Could i assume the eye-to-eye length as standard would be the same distance as the chassis pickup points so the shackle would be vertical when the oka is unladen?
Cheers, alister

The fronts don't pick up as much dirt as the rears so don't wear as much. I replaced all of them, because I could.
The top leaves were changed to 10mm a few years later for the upgrade of GVM to 6.6T.
I replaced the front again under insurance after the prang. Because I could.
Cheers,
Peter
