[31zook]

I've been trying to work out what sort if gearing to roll with in my zook so this is the info i found and collected i figured i may aswell share it. If anyone else know of other ring and pin for Vitaras that will fit sierra housings then tell me and ill put it in

Sierra, High: 1.409, Low: 2.268
Sierra ring and pin: 3.9, 3.7, 4.1

Superior Engineering, ring and pin: 4.57, 5.38
Snake Racing: Series One, High: 12%/1.691, Low: 4.16
Snake Racing: Series Two, High: 18%/2.536, Low: 5.14
Snake Racing: Series Three, High: 20%/2.818, Low: 6.5
Superior Engineering: High: 16%/2.254, Low: 4.9

Vitara, High: 1.00, Low: 1.907
Vitara ring and pin: 5.12
X-90 4.875

BBM, High:N/A, low: 110%/2.187
Snake Racing, high: N/A: 120%/2.206

X-90 are 4.875

Trail Tough are 18%/1.663 high 6.4 low

and a much better gearing calc: http://www.lepayne.com/gears.html

I don't think all X-90s are 4.875, but I have some R&Ps at home that are.

[303zuke]

And SE416 Vits with 3 speed Auto are 4.625:1

The ratios you've shown for the stock Sierra are for the 1.3lt transfer gears.

The 1.0lt cases are:
High:1.590, Low: 2.558

The 4.16 gear sets are a hybrid of the 1.0 and 1.3 gears and the High is the stock 1.0 ratio of 1.590 and the Low is 4.16.

Are those ratios correct, as they don't appear to be 110% or 120% lower than stock?

Calmini and Lowrange Offroad have Vitara 4.24 t/case gears which are 134% lower than the 1.907 stock.

The 1.0lt cases are:

The 4.16 gear sets are a hybrid of the 1.0 and 1.3 gears and the High is the stock 1.0 ratio of 1.590 and the Low is 4.16.

I made this up and it may be of some help to someone (numbers on the gears are number of teeth).

Each of the 4.16, 4.9 and 5.14 gear sets keep the original 1.3lt low range output gear and only replace the others. This may be good to know if you start off with a 1.0lt case as you won't have the full set of gears to make up the new ratios.

The 4.16 gears use the input and high output gear from a 1.0lt case, so if you have a 1.0lt case, you will need to find a 1.3 Low output gear.

The 6.5 gears replace all gears in the case with new items, you don't need any gears from your original gearset.

This may be a real stupid question but can stock WT transfer retain it's stock 1:409 High Range but have a lower than stock Low Range installed?

[BlueSuzy]

Maybe, But all gearsets come out with both reduced.

I use this gear calculator, allows you to compare as well as input tire size and gives you crawl speed, speed at given rpm and rpm at given speed.

I was using the imperial one for a few weeks until I realised the metric one was working.

heres a site that tells you the size of tires and the actual size of them plus some calculators to help out with gear ratio and stuff

The closest to feasible way I can see you doing this, is to make a cut and shut 'lobster' using a standard 1.3 case, and a set of 6.5's. Use the input and high range gears sets from the standard case, and the 2 low range gears from some 6.5's. You'll end up with the standard 1.409 high range, and a slightly lower 2.7:1 low range.

I theory you could cut and shut any pairs of these gears to give a few other gearing options...

[zukenutter]

after a day of swapping transfers I've just come to the realisation that I'm screwed. My plan was to swap my old 2001 Jimny transfer (with 24% reduction gears into my new VVT Jimny. Only problem while installing it was that the Jack shaft was too short, it still went on but obviously with less overlapping spline. I had a 2001 Jack shaft under the house which was the correct length but the spline although appearing the same wouldn't slide on to the gearbox output. I test drove it with the shorter shaft only to realise that the standard VVT transfer is much taller geared... end result was a top speed of about 90km/h in 5th and doing 5000rpm, not my desired outcome.

Got home and checked the VVT transfer high range ratio and it was 1.0 as opposed to 1.3.

So now I know I could fit a standard early M series transfer for a 30% reduction but that's too much. Sierra case is now way past what I want as well. Is their a Suzuki transfer with a high range ratio of 1.1 or similar?

This sounds perfect. Could it be done using low range gears from a one litre.

Sort of yes, but it would be silly.
You'd end up with a low range that is higher than the factory 1.3 case gives.

The only one worth doing would be using the low range gears from the 6.5's. All the other after market gearsets use the low range gears from a standard 1.3 case.

Now I'm confused.

Jimny NON VVT, High 1.32, Low 2.145

Sierra 1.3, High: 1.409, Low: 2.268
Sierra 1.0, High: 1.590, Low: 2.558

I want, High: 1.409, Low: 2.558

The way Sierra transfers work, is low range is dependent on the high range gearing. You change high, low changes with it. You can change low without effecting high, but there are only 3 different pairs of low range gears:
The 1L pair: 47/32 ~ 1.47 (only used in standard 1L light cases)
The 1.3 pair: 56/23 ~ 2.43 (used in 1.3 cases, 4.16, 4.9 and 5.12)
the 6.5 pair: 67/23 ~ 2.91 (only used in 6.5 gears)

These are not your overall low rage ratios, these values have to be multiplied by the input pair of gears. The input gears are different on every single Sierra case variant. The only one thats used twice is the 1L pair, which are used in the 4.16 rocklobster. All input gears are a reduction pair, except the 1.3 case, which is actually an overdrive! This is why replacing the 1.3 high range gears with 1L high range gears gives the significant change in low, as the low range pair is now multiplied by a reduction pair of gears.


As for wanting "I want, High: 1.409, Low: 2.558", you cannot do it. The closest is all the 1.3 high range gears, and the 6.5 low range pair. This gives you 1.409, 2.7.


Just for completeness sake, take the 1.409 high range set, and mix it with all 3 low range pairs listed above:
The 1L pair: 1.409, 1.37
The 1.3 pair: 1.409, 2.27
the 6.5 pair: 1.409, 2.71

Pretty bad when the low range ends up higher than high range!
BTW, basically all the info you need is in that diagram 303zuke posted above.

[Highway-Star]

OK, I've photochopped 303zukes diagram so you can see how its calculated.



Use the teeth count instead of numbers 1, 2, 3, 4, 5.

When mixing and matching gears; 1,2,3 have to remain as a matched set, and 4,5 have to remain a matched pair. When physically making them, gears 2 and 4 are joined together on one "shaft", and thats the shaft that gets cut and welded in a rocklobster.

[zukenutter]

Cheers Aaron, I should have referred back to that diagram as it does explain things well. I wasn't keeping the input gear in mind. BTW i really like your avatar.

is there any diff gears out there that will fit a jimny

Jimny ones...

Japanese domestic market should have 5.375:1 diffs from K6a auto Jimnys that might fit, if its low you are after...

[boostedbrick]

Just trying to work out some gearing here. See if i worked it out correct.

1.6 EFI, 3 speed auto, stock sierra trans, 3.7's
27" 4055RPM at 100kph
28" 3910RPM at 100kph..

1.6 EFI, 3 speed auto, stock vit transfer, 3.7's
27" 2878RPM at 100kph
28" 2775RPM at 100kph

Can anyone see an issue with 2900RPM at 100, or is that going to be too low?

I want to stick with a 3 speed due to size. So i've only got transfer or diff gears to play with. Id prefer not touch diffs though.

Too little RPM for a zook to be happy. Plus the low range would be horrid, and the Vitara transfer will not even close to be a good idea to use in a Sierra.

the 3900rpm might be OK. If you really wanted to get some slightly higher road gearing into it, put a coily transfer in (will need front tailshaft and maybe jackshaft? to go with it). I think your low would suck then though....
