hatch789,
I am not quite sure what differences there are between your machine and a 2UVR or 2UVR-c head if any. Is it a vari-drive head? If it is the same then removing the main belt is not too difficult. First get the speed up to the top, this gets the belt deep into the driven pulley. Next without the machine running back down the speed knob to take the motor pulley's grip off the belt. Do not turn the spindle or the belt will squeeze out of the driven pulley. Remove the four bolts holding the motor, slide the motor toward the left (facing front of machine) then you should be able to tilt the motor to the left up and out.
I hope this is clear, if not I will try to expand on my explanation. Also I do have the manual on PDF. If you PM me your e-mail address and I'll send it to you. It is for a 2UVR-C so a lot of it may not help. If you can send me a picture of your machine.
Good luck,
Gary
