Leveling Rear Roller - Toro Reelmaster 3100-D Service Manual

Leveling Rear Roller

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 adjust-
ment 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 bedknife is properly adjusted to cut-
ting reel.
3. Check if the rear roller is level to the cutting reel by
using a 0.005" (0.13 mm) 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 op-
posite end. Check rear roller with the feeler gauge just
inside the machined ends of the roller. A frame adjust-
ment should be made if there is consistently more than
0.005" (0.13 mm) 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 (Fig. 18).
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 27 to 33 ft−lb (37 to 44 N−m).
6. After tightening the side plate, recheck the rear roller.
If necessary, loosen and adjust second side plate.
7. If rear roller is still not level after adjusting both side
plates, check to see if cutting reel is tapered (see Pre-
paring Reel for Grinding in the Service and Repairs sec-
tion of this chapter). If cutting reel is not tapered and rear
roller is not level, a 0.010" shim (part number 107−4001)
is available to allow additional rear roller adjustment.
The shim would be used on one side of the rear roller
and should be installed between the rear roller bracket
and roller shim (Fig. 19).
8. After leveling rear roller, complete cutting unit set−up
and adjustment sequence.
