CAUTION
Never work on the mower with the engine
running. Always stop the engine and re-
move the high tension lead from the spark
plug first.
Leveling Drum to Reel
1. Make sure engine is OFF. Remove high tension
lead from the spark plug.
2. Position mower on a flat level surface, preferably a
precision steel work plate. Place a 1/4–inch x 1–inch flat
steel strip, approximately 24 inches long, under the reel
blades and against the front edge of the bedknife to pre-
vent the bedbar from resting on the work surface.
3. Raise front roller so only the rear drum and reel are
on the surface.
4. Firmly press down on mower above the reel so all
reel blades contact the steel strip.
5. While pressing down on reel, slide a feeler gauge
under one end of the drum, then check the other end of
the drum. If there is a gap between the drum and the
work surface, greater than 0.010 inch (0.254 mm), on ei-
ther end, an adjustment to the drum is required, proceed
to step 5. If the gap is less than 0.010 inch (0.254 mm)
no adjustment is required.
6. Remove rear belt cover from right side of mower.
7. Rotate drive pulley until holes align with all four roller
bearing flange screws (Fig. 7).
8. Loosen all four roller bearing screws and screw se-
curing idler pulley. Raise or lower right side of drum as-
sembly until the gap is reduced to less than 0.010 inch
(0.254 mm). Torque drum bearing cap screws from 16
to 20 ft–lbs (2.2 to 2.8 kg–m) (Fig. 7). Adjust belt ten-
sion and tighten idler pulley mounting screw (see Drive
Belt in Adjustments section of Chapter 4 – Traction and
Reel Drive System).
