New Mahindra Legend

[4x4addict]

I also noticed that the Legend comes with 235/70/R16 tires and the army mm550 with 7.50x16 tires. The diameter of the 7.5x16 is about 8.5% larger than the 235/70/16 tires. I hope Mahindra has made some adjustments to the differentials/gear ratio's to compensate for the smaller tire size. Otherwise the Legend will be running at much higher RPMs at the same engine speed as the the army MM550. But then again it has a 5 speed as opposed to a 4 speed in the army spec jeep so maybe the additional over-drive gear compensates for smaller tires.

Just as Jeep wrote the book on four-wheel-drive, Warn Industries wrote the book on locking hubs. They were founded in Seattle in 1948 by Arthur Warn to produce locking hubs for surplus World War II Jeeps.

On the Mahindra Jeeps, M&M never modified the WW-II front hub design.
So freewheeling hubs from the aftermarket for the 1953-1964 Willys CJ-3B and 1955-1971 Willys CJ-5 10-spline front driveshaft would fit straight away.

I had Warn premium (chrome & brass) manual free-wheeling hubs on my 1988 Mahindra MM 540 4x4. It took some research to find the right model.

The body was powdercoated black, the bezel was chromed brass and the dial was made of a brass-colored Zinc-Aluminum alloy.

As Jeep used higher torque engines after 1970, they increased the splines on the front driveshaft from 10 to 27. However the Mahindras still used 10-spline halfshafts.

I purchased my 10-spline Warn 29062 from a speedshop near my home in Kingston, NY. Came with a lifetime warranty.

Cost under $200 [= Rs. 7,500 these days] for the pair. Brought them back with me for the MM540 in Bombay. Fit perfectly on the Mahindra !
