Requirements Description:  This award is for a procurement of new, crankshaft assemblies for use in the AVDS-1790 diesel engines which power the M88 FOV. The engines are described as a 750-1050 horsepower turbo-supercharged, fuel-injected, 12-cylinder, 90 degree V-type, 4-cycle air-cooled diesel engine.  The crankshaft is the heart of the AVDS-1790 and is the component that harnesses the reciprocating force imparted onto the piston and rod assemblies due to combustion and transforms it into rotational force.

The AVDS-1790 2-series and AVDS-1790-8CR is the heart of the M88 Recovery Vehicle Platforms and makes mobility and recovery operations possible. The crankshaft assemblies are an integral part of the AVDS-1790 family of diesel engines. The crankshaft is the heart of the AVDS-1790 engine’s rotating assembly. It is geometrically tailored to the engine block architecture. The crankshaft has specific spacing and diameter so that it can fit securely into the block’s seven main caps that secure it. Also, the connecting rod journal size is uniquely sized to the crankshaft rod journals. Finally the crankshaft offset or ‘throw’ has been chosen to accommodate the stroke and valve clearance dimensional needs which are part of the recipe which gives the AVDS-1790 is power output capabilities.
