4. Loosen the jam nut
(A, Figure 27) securing the transfer
rod

5. Turn the rod in or out of the ball joint until the end of
the rod aligns with the hole
(E) in the driven disc assem-
bly from which the rod was removed.
IMPORTANT: Do not move the pivot bracket.
6. Reinstall the rod as removed in Step 2. Move the ground
speed control to the ‘slow’ position, then back to the
‘fast’ position. Recheck the 1/8” measurement described
previously. Readjust as needed. Tighten the nut when
finished.
7. Reinstall the driven disc spring to the driven disc
assembly.
Driven Disc Replacement
If the rubber on the driven disc is badly chunked or worn, it
must be replaced. Install a new driven disc as follows:
1. Remove the pin and washer
(C, Figure 25) from the
transfer rod
(D), and remove the end of the transfer rod
from the hole in the driven disc assembly.
