4.3.5. Replacing Bearing In Driven Disc Assembly
IMPORTANT: The bearing, on these "M" series Non-
Commercial machines, is staked into the thrust plate.
The bearing will have to be driven out with a mallet and a

disc assembly and replace bearing as follows:
1. Using a small flat blade screwdriver, free the clip
from the transfer rod. Then remove the transfer rod
from the clip and the speed control rod. See Figure
4.11.

and slide the driven disc assembly off the hex shaft.
See Figure 4.12.

driven disc hub to thrust plate. See Figure 4.13.
4. Slide the rubber driven disc hub out of the
bearing.
5. Drive out existing bearing.

with four retaining screws. Tighten screws securely.
