tram motor installation WARNING! Do not reconnect the trailing cable to the miner while the power cable is detached from the motor. Serious injury or death or damage to the machine may result.
22. To prevent damage to the power cable lugs and gland assembly, cover the power cable and secure it to the miner in a safe location. The manufacturer also recommends replacing motor gear case input seals for all motors.
23. To protect the motor’s electrical connections, replace the motor hand hole cover and o-ring and secure using the socket head capscrews and hi-collar lock washers.
24. Carefully remove the tram motor from the tram case and slide onto blocking. Clean out tram motor housing.
25. Remove the tram motor cooling water bypass hose that connects the two cooling water fittings on the rear of the tram motor and store in a safe place.
26. Clean out tram motor housing.
WARNING! You could be seriously injured or killed by falling loads. Observe the safe working load limits of all blocking devices.
To install the tram motor:
1. Replace the seal on the motor adapter plate, which is positioned against the primary planetary (Fig. 188).
