13-Ton Prime Mover Model 95B (1935)

This prime mover makes use of the same chassis as the Model 95A, the only difference being its accommodation of a 6-cylinder, in-line, water-cooled, valve-in-head Diesel engine. The cylinder diameter is 140 mm, the piston stroke 190 mm, and compression ratio 15.5:1. The normal horsepower is rated at 145 at 1,300 r.p.m. Maximum hp. is 165. The firing order is 1-5-3-6-2-4. There is a 24-v., 300-w. capacity charging generator, two 12-v., 80 amp.-hr. batteries, and two 24-v., 6-hp. electric starting motors.

Details are lacking on the reduction gear, which has a ratio of 2.92:1. The steering system is of the clutch brake type assisted on short turns by hand- and foot-operated control brakes, which include a locking feature. The transmission is said to be synchromesh with 4 speeds forward and 1 reverse. The maximum speedis 8.68 m.p.h. A gear-type forced-feed system is used for distributing lubricating oil in the crankcase. An oil pressure gage and oil-level stick are also fitted. Diesel oil fuel is supplied from a total storage capacity of 68 gals. Forty-four liters (11.6 gals.) of water are circulated from the radiator to the engine block with the normal type pump. This vehicle is said to be capable of ascending a 15° grade while towing a 14-ton load, or a 7 1/2° grade pulling a 32-ton load. The winch capacity is 11 tons.
