TRAM MOTOR – 2000 SERIES; 11.9 cu. in.
purpose
The tram motor, which is coupled to the torque hub, drives the crawler tracks by utilizing hydraulic power at 195cc displacement. For final speeds, torque ratings and drawbar pull see the “Drive Stats” heading under the “Belt Tailpiece System Statistics” section.
The motor has a 2-bolt SAE A mounting flange and is assembled with, precision made, high-strength steel machined and cast parts. The motor has a Geroler displacement mechanism that provides a high starting and running torque. The Geroler element minimizes friction and thereby increases efficiency while providing smooth output shaft rotation even at low speeds. The motor shaft rotation can be instantly reversed by changing direction of input/output flow while generating equal torque in either. The fluid is distributed to the Geroler pockets through a patented wear compensated disc valve. The pressure balanced sealing surface on the valve face provides minimal leakage. The motor is completely sealed so they can operate safely and reliably in hostile environments such as dust, dirt, steam, water, and heat and provide a highly efficient reliable performance.
Visually inspect the motor and hydraulic connection for leaks or damage and replace or repair if necessary. The motor should be examined and, if necessary, rebuild after every panel to ensure a reliable and long life.
Hydraulic power is supplied to the motor by two high-pressure inlet lines that are controlled by the valves found in the control bank (see the “Multi-section Control Valve” section).
