so in general highway driving the 2 inch track difference will not cause any problems.

but when a jeeps try to cross ditch or small river stream on tree logs the 2 inch track difference is not Ideal.

Attachment 814581

Attachment 814583

Attachment 814585
simple mod will be adding spacer of 2 inch which is not recommended by many gurus.

or installing new wider axle from mm FC ot mm Maxx series with tack of 1500mm (-+10mm).

BTW have you driven Armada/Bolero'550 NGCS ?

& tried to avoid potholes while driving one?
result the front tyre avoids it & reat dosent .

Hi Nikhil,

What problems will a variation in Wheel Tracks create while driving over such log/narrow bridges?

Even with a 6" Difference in Wheel Track 57Front & 51Rear I had no such problems. Just that it look FUGLY.

wrt to Pot Holes if the front avoids it and the rear doesn't that means the pot hole is 2-2.1" wide

What is the width of the tyre?

Regards,

Arka

give me some examples of vehicles with track difference of 100 mm.
Autorickshaw
Ok i know thats a poor attempt at humor

A track width difference of 10cm is huge. Apart from log crossings wouldn't that also affect while traversing deep slush/snow where the rear wheels can't fit in the rut carved by the fronts?

Edit: Just read Arka's reply. So its a non issue after all apart from the looks?

haven't crossed any but in general the track should be equal. (+-10mm difference will not matter)
see this pic

with 4 inch track difference the vehicle will be unsteady while crossing such obstacle but it will be manageable.




if such thing happnes here , vehicle & driver will be deep *** (MUD).

a good driver can drive a vehicle on 2 wheels too.

i have done it with Scorpio. (had to spend 1.5L on it afterward )

dont remember exactly there are billions of them.

EDIT:
i suggest to have one log crossing obstacle at TPC & AKC next season . (with 1ft high of cource)

we will have all the answers.

@ tejas
By modifying the differential what i meant to do was to shorten the length of the axle as well as the differential tube and bring it at par with the rear one.But the experiment would have resulted in ruining the whole front setup if it is not successful because while the tube one has to alter the fixing points as well as shorten the sway bar.

Hi Nikhil,

Please explain why a vehicle will be unsteady dues to a track difference of 4" .

What is the width of the logs? in the above videos

What is the width of the tyres in the above videos?

Regards,

Arka

PS -- I suggest you get your vehicle ready and participate in some off road events, you will have even more questions

see how the tyres slips on the logs.
this is what i was referring to as unsteady.

here the driver dose not know the exact position of tyres on the logs.
now if the front tyre is just on the log the rear tyre will be offset by 2 inches. (that is irrespective of tyre size )


so no matter how big tyre you use the rear tyre will be 2 inch in side & this increases chances of tyre slipping at the rear.

now what do you think would have happened if the red jeep in above video had lost grip on the rear right tyre while other three still on the logs??

EDIT:

BTW if you think i go hunting for people who use vehicles with such deformities , then you are wrong.

as i am using Bolero slx & Armada on daily basis.

its just that i dont like such hugh track difference & i am planning to change that on the Armada as well. (dont know when it will actually happen)

Hi Nikhil,

The Rear Track Width and Front Track Width will intersect or overlap.

Front Tyre Section Width (7.50X16) 160mm (approx)

Rear Tyre Section Width (7.50X16) 160mm (approx)

Offset at Rear 50mm

50mm offset is easily accommodated due to the with of the tyres being considerably more 50mm.

Even if a log bridge is just as wide as the Rear Track or Just as wide as the Front track the vehicle will pass with out any fuss.

Because the Difference in Track allows the wheels to over lap at the section width.

What you are trying to speculate will hold true only if the Section Width of the Tyres are considerably less than the difference in track width (2.1" Tyres) or if the Difference in Track Width is more than the width of the Tyre (7.5"-10"), or if the diameter of the logs are lesser than or equal to the off-set between Front & Rear Tracks (2.5")

Regards,

Arka

Hi Nikhil,

You don't need to hunt for people with, vehicles with such deformities because you have two of them in your Garage.

But have you used any of them extensively off-road with a working 4WD?

If the Track width was so problematic then M&M wouldn't have made them for the past 10yrs on their Largest selling vehicles i.e Bolero & Scorpio.

In case you have some in depth or ingenious idea as to why M&M ended with such deformities please do share with us.

Also do share with us how to correct such deformities in our vehicles.

Regards,

Arka

i am facing the same problem with my Armada.

its your choice to do it & how to do it.

Hi Nikhil,

You definitely are a Killer, I pray please tell me how you will fit a 58" FC Van in a Armada/NGCS vehicle.

Regards,

Arka

PS - The track difference will be 12.7 mm per side

first i will source a 58" axle & then figure out the way to fit it.

there are some vehicles with such mods here.

will try to get some tips from them. (if they are willing to share, other wise it will be me & google )

Hi Nikhil,

How types of 58" FFRA have been manufactured? Which one will you use.

What type os axle will you use, what hub and spindle will you use?

Please do share with us to prevent us from googling.

Arka

Default Re: Difference in the track width of the mm 550 ngcs .

Pardon me for jumping in.. but is the track difference really that much troublesome?
If that is the case how did the Indian Army managed to use these jeeps all these years? They must been to many remote & offroad places..

Just a thought

BTW: As per M&M, the track difference is to reduce the turning radius so what is the turning radius for Thar CRDE (57"-53") & Thar MDI (51""-51")?

Thanks Arka for the illustration.

(OT: Dear Sammy, how much you paid for NGCS 550. Can you please post some pics here?)

AFAIK only 2 types one for SPOA (FC) & one for SPUA (MAXX) woth different pinion angles. (excluding the offset of the diff's)

Hi Nikhil,

IIRC the FC is 58"and the MAXX Pickup is 59" .

So what are the Differential Off-Set Available with the above two FFRA's?

If you use the MAXX typer FFRA your Rear Track will increase by 25.4mm on each side.

Get your Axles ready and I will surely tell you what little I know.

Regards,

Arka
