1. Remove the rear bolt holding the gearbox to the side-shift frame.
2. Slide the side-shift frame over until the gearbox is off the hexagonal shaft.
3. Unbolt the bolts holding the front plate to the side-shift frame.
4. Whenever the bearings are removed from the gearbox, all oil seals should be
replaced to assure no leaks when the box is reassembled.
5. To avoid damage to components, bearings should always be removed with bearing
pullers and pressed in when being replaced.
6. When reassembling the gearbox, ensure that there is precise mesh between ring
and pinion gears.
To remove the chain do the following:

Removing the rotor is a simple operation. The complete rotor consists of a center rotor
made of heavy piping with blade flanges welded to it in a scrolled pattern and two side
support flanges (one right and one left). The center rotor is attached to the two side
support flanges with special bolts. To remove the center rotor, simply remove these
bolts and slip the center rotor out from the two support flanges.
