M-32 Chenca

     Notes: This Mexican version of the M-32B1 Sherman-based Tank Recovery Vehicle differs from chiefly in the engine used and the abilities of its recovery and engineering equipment.  The final drives have brackets added to allow mounting of a dozer blade, and the engine is an earlier version of that mounted on the Stingray tank.  The Chenca is designed for use by both recovery and combat engineer vehicle, with a wide variety of tools and weapons for this purpose.  Primary recovery equipment is a winch in the front hull with a capacity of 27 tons, or double that if block and tackle is used; the cable is lead out of the glacis plate, and the reel is located behind the driverís seat.  There is also an A-frame crane with a capacity of 9 tons, or 14 tons if the vehicle is stationary and the bogies locked.  The turret is replaced with a circular superstructure.  A large amount of tools are carried containing almost anything a recovery mechanic or combat engineer could need, including basic, tracked vehicle, wheeled vehicle, excavating, power, small arms, and heavy ordinance tools; a jackhammer, a chainsaw, an air compressor, up to 6 fire extinguishers, and a combat engineerís chest.  The Chenca uses the Detroit Diesel 8V-82-T, a derivative of the M-113A3's engine, developing 300 horsepower. Due to budgetary considerations, the Mexican Army was not able to buy more up-to-date equipment and her plans to get a Leopard 1 ARV version was called off, leaving it with obsolete recovery vehicles and engineer vehicles.  The Chenca was forced to into both the recovery and engineer roles.
