The coily's transfer case has been abused and misused heading for a rebuild so I'm chasing something with lower gears or tha can be rebuilt with lower gears..............what's out there

[ellis]

umm u might want to look into 1.3 case with reduction gears fitted i think u have to chage jack shaft and t case mounts and thats it but i am unsure if thats all u have 2 do

[96coily]

Yeah I think I might have to change the flanges too but that seems to be what I'm chasing

Wt shaft, brackets and flanges I'm in the middle of doing one in mine.

You will need to do the leafy transfer conversion to get better gearing options.

You have a couple of choices.

Fit a standard later model 1L transfer ( has 4wd switch)
Fit a 1.3L transfer with any aftermarket reduction gear set.

Thats it

[Hotshot993]

yeah thats what i thought too fatzook, the 1l transfer, easy as piss to do right?

If you have a leafy Sierra. 1 litre cases are becoming harder to find also.

[96coily]

Cheers, here's some pricey shite there lol
I diffenately need something other than the original coily to rebuild
I'd rather buy something with more options for gearing
What ratio did you go Rusho with your 30" MU's

[Hotshot993]

yeah leafy all the way, i dont wanna get stuck with a coily

[96coily]

Coily's don't get stuck noobie

[Hotshot993]

No as in don't want to get stuck with one. I would rather a leafy. And I know coily are capable offroad. Wet glasshouse today in one. Stock as and went like a legend.

kevin - once you get your new diff under you won't need tcase gears... just put a standard 1.3 case in and you should be fine - or even cheaper, just replace the coily case. it'd be the weak link though once those diffs go in.

Are you suggesting that diff gears are better than transfer gears? I'm fairly certain this discussion just happened only last week.

OP. If you have to spend money rebuilding your coily case, then IMO, and probably alot of other peoples, you should buy the cheapest, noisiest 1.3L T-fer you can find (WT if possible) and buy a gearset and bearing kit from the US. It should cost you under $800, and you won't have to touch gearing ever again.

Just my thoughts on the matter.

Yeah Fatz, see the difference is that Aron knows, that I have a set of Volvo 303 portal axles that eventually are going under the coily... So I'm not really worried about diffs and axles....should be fun with 37's

You'll still need transfer gears with 37's. 303's are 5.99:1 ? so thats 33% reduction from the axle. A 37" is roughly 30% bigger than a 26", so your new axles will only get you back to stock. This may suit you, but with 37's and portals I'm guessing you will still want transfer gears.

Sorry if my calcs are wrong.

[96coily]

The portals are 7.11 : 1 but I think when I have them in I would only run 35's. 37's would be rediculous.
Besides I'd hate to embarrass all the leafies in the world
I think ajax make a heavy duty TC but I don't know anyone running one
I still need to find out what is needed for the engineering



Leafs are for rolling and smoking haha

7.1's. Well thats a little different. She'll be slow in the highway

Who is ajax? do you mean Atlas?

[96coily]

Yikes getting my greek mythology in a muddle.
Yeah I meant Atlas but I won't need that straight away
I sure will miss the sierra top end highway speed

6.5's They are the cheapest from lowrange and eventually I will get some 31's. 3rd gear will be my new best friend in lowrange

[Teracis]

I don't know if it was here but I was reading the other day that one of these ratios gets the gears to pretty much line up from low range to high range. I.E. Low 1-5 then High 1-5 With High 1 being just higher than low 5?

Just wondering if that's the case and which ratio that would be. Also, I've just got a 1990 which has a 2 inch body lift and I don't know if it has any spring lift but It's running 31's afaik and I will need to get some new tcase gears to get it set up better. Is there anywhere in Oz/SEQ that sells/fits these? Or is my best bet to order a set from the states and fit them myself? I'm plenty handy enough with the tools, provided it comes with instructions and I have the right gear I wouldn't be scared, just wondering about options.

Thanks all

[Rusho]

Gears are more expensive over here, better off getting them from the states. The instructions are pretty comprehensive and easy to follow.

[jonno_racing]

on a side note where the hell did u find a set of volvo portals??????????

[96coily]

Mate of mines into Unimogs and picked them up cause thery were cheap, but he had no real use for them and I thought ooooh...
Lift, gear reduction, wider stance and twin lockers plus I can run huge tread ...that'll be fun

[96coily]

I want a 1 litre tran case with switch good condition

I've been looking at the sets on Low Range Off Road, more specifically the trail crawler stuff.

It won't be till after I get the engine running right and the seats replaced, but it seems to be the site most referred to here e.t.c.
I'd prefer to not have to grind the tcase out though but can't work out which is the biggest reduction that doesn't require modification.
Also it seems that the only place to get 5.14 reduction is the calmini kit from spidertraxx. On the low range site there's a table that includes 6.4:1 reduction (as opposed to the 6.5 they sell) but I can't find those anywhere.

Thanks in advance for any extra info!

Lowrange service and products are highly recommended.
6.4 gearsets are Rockhopper and come with NO warranty.
Trail crawler 6.5 gearsets are unconditionally guaranteed...
Fitting is easy enough and don't be worried about the grinding, it is only very small amount that needs shaving off. An angle grinder does it in a second.
Comprehensive fitting instructions are on the Lowrange website...

[Teracis]

Thanks for that, I'm not at all afraid of the grinder, just didn't want to weaken anything. I hope 6.5 isn't too low, not that I do much highway although 5th is too tall for anything at the moment...

EDIT: Now that I'm not typing from my phone, I think the 6.5's will be the way to go, should make it a lot nicer to drive. Now that I've got that sorted I just have to put it on the list, which is unfortunately 3rd behind the carby problem and the rooted seats.
