I guess easy is realative but if I can do it I feel it can't be to difficult. You really should have a copy of the service manual first of all so you know what you are getting into.
- You have to remove the transport and remove the slde drive assembly from the transport.
- Use deoxit on the sled drive motor and run the motor in forward and reverse using a nine volt battery.
- While I was in mine I lubed the sled drive and regreasesd the spindle motor.
The above may sound intimadating but it really isn't as long as you keep your head about you and take it slow and methodical.
If you e-mail me I can send you the service manual e-copy if you like.
Hope this helps.
