Gypsy Gear ratios

[MexXxentric]

Experts,
Can you please enlighten me on the gear box ratios, transfer case ratios and axle ratio of Gypsy 410W and 413W?

As far as i know, the gear ratios of 410W and 413W are the same
First -3.14
Second -1.95
Third - 1.42
Fourth - 1
Fifth - 0.79 ( In 413 W)

What are the T.C ratios (H&L)?
Is there any difference in transfercase ratios of 410W and 413?

What are the axle ratios of 410W and 413.

[Blue Thunder]

AFAIK,

High --> 1.409
Low --> 2.268

same in both the 410W and the King

Axle ratio --> 3.727

same in both the 410W and the King.

Thanks blue thunder.
from where did you get this info?

One of my friends running a garage send me these values(said to be from service manual)

DIFFERENTIAL RATIOS

MG410W

HI :1.578
LOW :2.511

MG413W

HI :1.409
LOW:2.268

He was not aware of the differential reduction ratio.
if the TC ratios are different, differential ratios also should be different to maintain the final drive speed.

can anyone confirm this?

dwarak, Arka, Khan... help me

Does this means that when you shift the Gypsy 413W from 2H to 4H the gear ratios are multplied by 1.4 ? i.e. in 4 H instead of 1:1 the gearing becomes 1.4409 : 1 , close to the 3rd gear in 2 H ?

[khan_sultan]

Don't know about MG410 but this is what is there in MG413W

Gearing:
-----------
1st 3.652
2nd 1.947
3rd 1.423
4th 1.000
5th 0.795
Reverse 3.466

TC-High: 1.409
TC-Low: 2.268

Axle: 3.73:1

Hope this helps.

[desertfox]

Thanks, but when you shift the 413W from 2H to 4 H does a transfer case ratio of 1.409 apply like a ratio of 2.268 would apply if shifted to 4L

Also Shawnawaz is there a topic on modifications ( performance mods ) for Gypsy 413W pertaining to K & N Filters, Lights, Suspension and exaust ?

Honestly, I don't know for sure. I thought that it was the case but I have my doubts and am not 100% sure either way. Maybe some expert can throw light on that.

is there a topic on modifications ( performance mods ) for Gypsy 413W pertaining to K & N Filters, Lights, Suspension and exaust ?

I don't know of specific thread but there would be details of these in various Gypsy threads out there. Just search for Gypsy in the title of threads and you should be able to find some info. I think that in the 4x4 section you would be hard pressed to find this info.

2H = 1.409
4H = 1.409 with front Axle engaged
4L = 2.268 with Fr & Rr Axle Engaged

From the internet...

Suzuki Samurai Gear Calculator

... since I dont have the service manual for the Gypsy, and there is no online info for the 410W, only the Gypsy King specs are available online.

If your friend is quoting from the Gypsy (India) service manual, then that should be correct. What I have taken from the internet is for the Suzuki Samurai (1986-1990), on the assumption that the Samurai of 1986 would be probably what was launched in India as the Gypsy (410W). This assumption could be wrong.

The service manual should also have the diff. axle ratio. Could you please check that as well?

No, sir.

As ex670c has mentioned above, the only thing that happens when shifting from 2H to 4H is the engagement of the front axles. There is no gearing change.

I guess this is true of any 4WD vehicle , and not just the Gypsy King.

[desertfox]

Thats what I guess too. Whether 2 H or 4 H the gear ratio would remain the same.

As for mods, thanks I found a source to purchase and fit the free flow exaust and K & N filter I wanted for my Gypsy MG413WMPFI in Delhi itself at a reasonable price. Will get these enhancements done soon, whenecer I find a bit of time to spare.

Here is the Transmisson and transfer case specs for 1986-1988 samurai(sj413):

Attaching the different ratios for the various Suzuki sj series:

[Crazy4Power]

It is still not clear whether the tranfer case of MG410W is same as MG413 in terms of gear ratio, mounting etc?

Gurus pls put some light on it

[IndrojitSircar]

So does one need to change the Axle ratios if one plans to do 1.6 conversion on a 1.3 carb gypsy?
