Leveling Rear Roller - Toro Reelmaster 3100-D Service Manual

Leveling Rear Roller

DPA Cutting Units: Adjustments
The precision machined components of the cutting unit frame keep the rear roller
and cutting reel in alignment (parallel). If the side plates are disassembled or as
the cutting reel wears, a limited amount of side plate adjustment is possible to
make sure that the cutting unit is properly aligned.
1. Place the assembled cutting unit on a surface plate.
2. Make sure that the bedknife is properly adjusted to the cutting reel.
3. Check if the rear roller is level to the cutting reel by using a 0.13 mm (0.005
in) feeler gauge to determine the clearance between the surface plate and
the rear roller at each end of the roller. As the rear roller is rotated one full
turn, check if the feeler gauge will consistently pass under the roller at one
end but will not pass under the opposite end. Check rear roller with the feeler
gauge just inside the machined ends of the roller. A frame adjustment should
be made if there is consistently more than 0.13 mm (0.005 in) clearance
under the roller on one end but not on the other.

4. Loosen, but do not remove, the three (3) shoulder bolts that secure the side
plate to the frame opposite the side that is not level
5. Adjust the position of the side plate to parallel the rear roller and cutting reel.
Then, tighten the shoulder bolts to a torque from 37 to 44 N-m (27 to 33 ft-lb).
6. After tightening the side plate, recheck the rear roller. If necessary, loosen
and adjust second side plate.
