The conveyor drive motor transmits torque to the head shaft assembly. It is also part of the head shaft assembly. As soon as any component of the assembly is warn or damaged, the component must be replaced.
How to remove the conveyor drive motor
To remove the conveyor drive motor proceed as follows (Fig. 81):
WARNING! Before performing maintenance on the machine, the circuit breaker must be in the “OFF” position and the power should be disconnected at the main power source. Electrical shock and accidental machine movement can cause serious injuries or even death to you or the maintenance person.
Disconnect, cap and tag all hydraulic hoses to the conveyor motor.
Remove the two (2) pins and cotter keys from the torque arm and remove torque arm connecting link.
Remove conveyor motor cover bolts and remove cover.
Remove torque mounting bolt located inside conveyor motor.
Attach an appropriate lifting device to two (2) of the conveyor motor torque arm mounting bolts and slowly slide the the motor from the coupling and headshaft.
WARNING! You could be seriously injured or even killed by falling loads. Observe the safe working load limits of lifting or blocking devices and keep a safe distance from suspended loads.
Disconnect lifting device and remove the torque arm mounting bolts.
Remove torque arm from conveyor motor.
Slide coupling from headshaft.
