These are OEM NCGS 550 rims. The NCGS 550 came with these rims even for the army. Have a look at the NCGS army 550 pictures posted elsewhere in this forum. The army 550s stopped coming with the heavy army rims that we are used to seeing after the NCGS upgrade. The PCD was changed for the NCGS. It is possible that this rim is shared with the Scorpio and Commander.

16 x 6.5 is good enough to take that tyre.

Lets wait for the owner to confirm, we might be talking of the same rim that came on both vehicles.

You have put me in a big confusion. I think commander rim is 4.5- 5.5J and not 6.5J. I agree on the same pattern. Check out 600 16 NDMS on latest commander. I dont think 6.00 16 tyre being so narrow can seat on 6.5J rim. 2wd commander come with 185/80 R 16 again unlikely to be seating on 6.5J rim. Not only commander now even major comes with same rim pattern. later model MM540 also had the same pattern but size differed.

4x4 addict- Please refer to my post 11. You will see the difference

YES... sorry for the confusion. I think i got confused due to the pattern and also due to the fact that the Scorpio wheels too came in the same pattern, which i was not aware of.

The Commander indeed came with 4.5 J. I stand corrected. A 4.5J cannot take that tyre.

I take back my post. These are indeed scorpio/marshal rims. The NCGS MM550 rims have circular holes that are in sets of two like on the Thar and the picture of the army 550 posted in Vinod's post # 11

Sorry to barge in guys but just had to say - In the second pic, the scorpio looks "WICKED"!

@Satheesh-Amazing find mate.

[NIP]

Wow Sateesh congrats on the find ! You are one lucky guy. The colour of the jeep is also very nice. From what I understand, the PCD in this vehicle is same as the scorpio ? Thats great news ! Please do share your buying experience and do post more pics.

Mahindra, please give us this vehicle in the showroom.

Hi guys
I am no expert whether MM550's came for civilians or not but this definitely looks like a mayapuri job!!! You see when jeeps are sold by the mayapuri guys to outstation clients they get some sort of a temp number.
I came to know of this when I was on the hunt for my jeep. I took some pictures of a 550 with the similar 'TEMP' T number.

The following picture was taken by me on 12th December 2008



Further I am enclosing some pictures of the 2005 model accidental vehicle that Naveen me me saw in Mayapuri.





So my bet is that this is an army disposal and if this is a later 2004 or a 2005 model than most probably its an accidental vehicle.
The latest good conditioned 550's that I have seen in Mayapuri are 2001 and very very rare 2002's

I too feel it is an ex-army jeep, reasons:

-The holes above and below the front indicators on the mudguards are of (removed) brush guards.
-The headlight brush guards too were only supplied to the army and never to any civilian 540/ 550.
-The right opening tailgate with the tubular bracket for the spare wheel, came on army 550's only.
- The side and rear grab handles also never came on any civilian model of Mahindra except the LEGEND.
-Fenders were OEM only on the LEGEND (in civilian jeeps).
-The rims are of Commander, if the PCD is the same for the 2002 MM550,
if not I am wrong.


Basic point is, if it was not bought direct from Mahindra, there is a greater chance of it being ex-army.

Please do not get me wrong, even if it an ex army it will not lessen the quality of the legendary 550. congratulations on your new jeep.

By the way, Sateesh never claimed it is a civilian 550?

Regards,

[4x4addict]

I too agree that it could be ex-army, but regardless Sateesh is the first person on this forum and jeepthrills who has got his hand on the NCGS MM550.

Hope he resurfaces to give us an update :-)

Dear all - some NGCS army vehicles were supplied in white colour and cream canopy from plant. I think they were for the military medical services. White vehicles went with these wheel rims. It will have an XD3 calibrated to 4500 rpm with oil cooler and cross flow radiator, so FIP should not be tampered with.

Best regards,

Behram sir,
I think all army XD3p's are caliberated to 4500 rpm. Can a normal pump be caliberated to 4500 rpm? Can i do it for my 2.1 litre pump? Also can one add a oil cooler to 2.1 litre engine? What are the advantages? Why army vehicles are specifically equipped with it?

Vinod, If the Oil filter assembly is the same for the 2.1 and 2.5, you can install the oil cooler. It is basically a water cooled bolt on unit. The installation is fairly simple. It sits in between the Oil Filter and the Engine Block. The process is pretty much 1) remove the oil filter, 2. Install the Oil Cooler, 3) bolt the oil filter into the oil cooler. 4) route the coolant through the oil cooler.

This is a question I too would like to be enlightened upon, the oil cooler did not come on all army 550's and the Voyager, though the specs are the same for these engines. Also can the oil cooler be added to a 2.1 and XD3P? Will it translate into a distinct advantage?

Sir Behram,
The white NGCS 550's were used by army medical units, DRDO and DRDL, but I think they were not supplied in the civilian market, please correct me if they were.
Since the past five years the white 550's all that I have seen had the 0091983, 5.50 F X 16 LP (10 oval holes wheel rims) and not a single was fitted with the round hole (like the ones on Sateesh's 550).
Please elaborate on FIP and the difference between a cross flow radiator and the regular one.
Regards,

I saw the parts manual for the Army spec XD3P engine in ML and was planning to order this if I went with the XD3P. ML or RK maybe able to get one for you. I think it is okay to use a second hand one from Mayapuri since the mechanism is very basic. Basically sits between the oil filter and engine block and has a pipe to let the coolant pass through it.
