DRIVE ASSEMBLY ADJUSTMENTS
DRIVE ROLLER TRAVEL HORIZONTAL
Disconnect spark plug lead; remove battery,
(electric
start models only,) stand mower on
tilt (knurfing) bar.
The cast iron bearing carrier of the drive
roller assembly must
be in contact with the
extended threaded ends of the screws holding
the hex shaft bearing retainers to the drive
bracket with the shift lever
placed in the
full reverse position (Figure
2-26.) This
will allow the drive roller to move across
the face of the drive disc as the operator
shifts through the
three forward speeds or
reverse. The drive roller must
be read-
justed whenever a new roller is installed.
To obtain
the correct adjustment proceed
as follows:
1. Place speed selector lever in "reverse."
Loosen jam nut on speed control rod.
(Figure
2-26.)
2. Remove nut securing ball joint stud to
bell arm assembly.
3. Turn ball joint onto the rod to lengthen
travel--off rod to shorten travel (Figure
2-26.) Proper adjustment does not nec-
essarily put the drive roller on center
line of drive disc when
shift lever is in
neutral.
4. When proper adjustment is made, attach
ball joint to the bell arm assembly and
tighten nut securely. Tighten jam nut up
against the
ball socket.
5. This is necessary to retain correct rear
speed.
Inspect the drive
disc closely. If the
surface is polished the rubber drive
roller will slip. Remove polish finish
by rubbing
in a circular pattern with
sand paper or emery cloth.
