Coily diff gears

Post by 2CRAZY »

Can the coily diff gears be interchanged with the WT or NT diff gears??
And what options are there for the Coily Gearing??

No and none.

The rear is interchangeable with any sierra. The front is unique to the coiler (it's high pinion)

You MIGHT be able to swap jimny gears into the front, but as you have 4.09 now and 99.9% of australian jimny's are 4.1, there's no point. THere is a very small chance you could come across a 4.3 jimny, but the hassle isn't worth it for such a small change in ratio.

The mythical M13 auto, but only in suzuki's brochure? :oops:? I know you have looked, but the brochure says they're real... so it must be true

acording to all my info the auto was ment to have a 3.9, and in south america they do (one chap had a 3.9 front and a 4.090 rear from new :shock: ).
and for some reason here in Oz thay have a 4.090

If the diff gears are out of the question!
How much is involved in putting a WT transfer case in the coily?

do a search - this has been covered heaps before. It's not too hard if you have the transfer and some driveshaft parts.

If you go a WT transfer you will need gears too. if you are running a 31 or smaller you might be better with a late 1.0 transfer as the gear ing is 26% lower in low range (and 12% in high) than what you have now.- might be enough without the expense of gears.

I have searched! but can not find what is involved in doing the swap!
If you can find it and post some links that would be very helpfull!
All I can find is where people with coily's have done the swap but that's it!

I was going to put gears in the WT transfer, either 4.9's or 5.14's for 31" or 32" tyres

Looks like me and Steve are both having a shocker - just checked and it looks like they are 3.9:1 final drive ratio.
:oops: :oops:

I pulled the front diff out of mine today (96 coily).

Crown = 43
Pinion = 11

That equals 3.91

Well yes... now :armsup: earlier, you would have had a ratio mismatch :oops:

Hang on, we're not talking about fit here, only ratio - The stock NT sierra rear is interchangeable with coiler, but the front is 100% unique to coiler and the only ratio is 3.9, so even though you can run 3.7, 3.9, 4.09, 4.3, 4.6, 5.12, (and mythically 5.38 and 5.83) in the rear you are still stuck with 3.9 in the front without significant other modifications.

you can change the knuckles and put in a low pinion 1.3 sierra centre with what ever gearing you like. the coily centre is 1.3 diameter, the jimny centre is 1.0 litre diameter.
