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. Using the surface plate, check if rear roller is level to
cutting reel by using a 0.005” (0.13 mm) shim at each
end of rear roller. If the shim will pass under the roller at
one end but not the other, a frame adjustment should be
made.
4. Loosen, but do not remove, the two (2) shoulder
bolts that securethe side plate to theframe opposite the
side that is not level (Fig. 11).
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 210 to 240 in--lb (24 to 27 N--m).
6. Aftertighteningtheside plate, recheck the rear roller.
If necessary, loosen and adjust second side plate.
