User:N K Gianchandani/Mahindra MM550XD

The Mahindra MM550XD is a miltary version of the Mahindra CJ540DP, (which is a 91" wheelbase version of the Jeep CJ5 model, with a Peugot licensed XDP 4.90 engine, which gives 62 bhp). The XD uses a Peugot XD3 engine, which gives about 72 bhp in civil form.   The older version had a four speed two range gearbox, with manual front axle hubs, later versions are with five speed (with low and high range) and fixed hubs in the front axles. The front axle can be driven or disconnected, more or less like in Jeeps. The low range is available in 4 x 4 only, ie you must engage the front axle drive before being able to use low range.   It has replaced the CJ3 and CJ4 petrol vehicles in the Indian armed forces, and also it has replaced the Jonga (1960s Nissan Patrol licensed by the Indian Ordnane Factories).   The older body was prone to cracking near the fender to body joint in front of the doors, but changes in the steel and design have reduced the problem. It is built as plain, ambulance, open, recoilles gun and other versions, the ambulance version appears to have a longer wheelbase. The tyre size is 7.00 x 16", compared to the civil MM540's 6.00 x 16" tyres, and the extra lighting equipment for night work is also a distinctive feature.
