The flow diagram illustrates the transfer of power generated by the powerplant to the track assembly.
a. POWERPLANT. The powerplant (1) can be removed from the vehicle as a complete unitthat consistsof anengine
(Model 7083--7396) (2) or LHR engine (Model 7083--7391) (3), transfer assembly (4), and transmission (5).
b. ENGINE (MODEL 7083--7396). Engine (Model 7083--7396) (2) is a liquid-cooled, two-stroke cycle, diesel-type,
model 8V71T equipped with an exhaust-driven turbocharger (6). The engine develops 405 horsepower at 2300
rpm and delivers power to the transfer assembly (4).
c.
LHR ENGINE (MODEL 7083--7391). LHR Engine (Model 7083--7391) (3) is a liquid-cooled, two-stroke cycle, low
heat rejection, diesel-type, model 8V71T equipped with an exhaust-driven turbocharger (6). The engine develops
440 horsepower at 2300 rpm, delivers power to the transfer assembly (4), and uses glow plugs (7).
d. TRANSFER ASSEMBLY. The transfer assembly (4) receives power from the engine (2 or 3) and transfers that
power to the transmission (5).
