Leveling The Rear Roller - Toro Greensmaster eFlex 1021 Service Manual

Leveling the 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 a
limited amount of side plate adjustment is possible to make sure that the rear
roller and cutting reel remain parallel.
Note: Use a pie tape to measure the reel diameter taper; service limit 0.25 mm
(0.01 inch). Leveling the rear roller of a cutting unit with a reel that exceeds the
reel diameter taper limit is not recommended.
1. Ensure that the cutting unit bedknife is properly adjusted to the reel; refer to
the cutting unit Operator's Manual.
2. Place the assembled cutting unit on a cutting unit bench plate so at least
three of the reel blades contact the bench plate rib.

3. Check if the rear roller is parallel to the cutting reel by trying to fit a 0.13 mm
(0.005 in) shim between the rear roller and the bench plate at each end of
rear roller. Rotate the roller and recheck the clearance at each end a few
times to account for any roller run-out. If the shim passes under the roller
through the entire roller rotation, the rear roller is not parallel to the reel or is
high on one side and an adjustment should be made.
Note: If the cutting unit has an optional rear roller adjustment kit (eccentric
roller shaft bushing), loosening the cutting unit side plate should not be
necessary. Adjust the rear roller by loosening the rear roller clamp fasteners
and rotating the eccentric bushing as necessary; refer to the rear roller
adjustment kit Installation Instructions for additional information.
4. Loosen, but do not remove, the two shoulder bolts that secure the side plate
to the frame on the side of the cutting unit where the rear roller is high (not
contacting the bench plate).
