Hmm , not that simple . Your thinking is not wrong but there is another angle for that .

Class/category of vehicle changes by weight , seats etc . & so will change the other mandatory requirements( necessities/formalities ) ,

Now effectively you will find the Jeep sitting next to SX 4 0r Honda city( may be , in legal terms ) & that translates to more costs

Or you will find it in commercial class , then its out of the OTR scenes .


Nikhil , its time to study law books , so next time you come to Pune there is a mandatory visit to a book shop ,( non auto books ) Dont worry , I will take you there.

i was referring about this aspect only raju bhai.

weight is to comply ECC/CMVR norms under M1 category.

& more people on bord are for less excise duty. (same reason for creating mm 650/750 LWB's in 80's~90's)

key difference between M,N categories is GVW.

its EEC not ECC.

A typical AC installation requires a compressor, that compressor has to be driven by the engine via the crankshaft pulley, then it becomes a natural requirement that the compressor must be mounted in such away that the belt line of the crankshaft pulley and the compressor pulley must lie in one plane, then it becomes natural to presume that the compressor would be mounted on the lower side of the engine in order to keep belt length small, then you would open the bonnet and look at the obvious mounting locations, then you would realize that this thing has a rigid axle which would move up and down and occupy precious space, so your eyes would move to the top of the engine, so you would want to mount it next to the rocker arm cover, then you would realize that there are not enough supporting points to locate the compressor here, then you would also realize if you could find place to fit the belt at all, the belt length taken from the crank shaft pulley would be very large which would result in belt whipping, then you would think of driving the compressor off the water pump pulley, then you would realize that the water pump pulley has a single groove, then you would think of making a double groove water pump pulley and even if you got away by mounting like this, you would ruin the water pump bearings prematurely. Whew! That was only a very small part of the compressor mounting DFMEA (Design Failure Mode Effect Analysis) and I have not yet really started the DFMEA. I think you have got the message. Next - where does the blower unit go? Where does the condenser go? Even if you somehow manage to do the whole thing, what would happen to the acceleration with a 3.73:1 axle ratio? Then, you would try and change the axle ratio as many of our common friends would advise you to do, maybe also a bigger length of axle with the great "FFRA", also with "something something" which may finally give you "nothing nothing" ????? .
Hi DB Sir,

IIRC the Bolero MDI3200TC is fitted with the A/C we can surely apply after-market parts bin assembly line technology and engineering.

w.r.t changing the differential ratio in a DANA 44 is pretty simple made simpler by the fact that the MDI3200TC has minimal electronics, governing the fuel pump.

Besides the 2010 NGCSMM550 (new Army JEEP (MDI ) is fitted with some of the above, excluding A/C of course.

Regards,

Arka

PS - You only have to guide us.

i had read some where about the weight difference, it also depends on engine power, privet/commercial use, no. of passengers etc.

i remember the post of Behram sir in crde thread about Thar with yellow no. plate without M1 spec's.

& spike. dont my leg , please give me a link where i can get clear information about vehicle categories.
(L1 ,L2, L1BOV ,L2BOV, M1, M2 ,M3, N1, N2, N3)

Sir, it is really great that DFMEA and PFMEA is applied. It would be wonderful, educative (and entertaining for some) if you could share the table along with the RPN values.

Thanks

Wait a min. are you implying the 2010 MM550 is the same as the Thar MDI,.albeit with different suspension mounts for the 7.5 x 16 sandgrips.

Hmm...if true then for the first time the civilians get the same jeep as the Army from the MM range!

no pictures. (was going for my EXAM)

(AFAIK this may be the first 4x4 sold by mm here from last 10+ years)

Any updates? Considering A.C. fitment on Crdi is not smooth either, one can choose lesser of the two Evils!
