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 three (3) shoulder
bolts that secure the side plate to the frame opposite the
side that is not level (Fig. 12).
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 tighteningthe side plate, recheckthe 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 nottapered and rear
roller is not level, a 0.010” shim(part number 107--4001)
is available to allow additional rear roller adjustment.
Use the shim on one side of the rear roller and install it
between the rear roller bracket and roller shim (Fig. 13).
8. After leveling rear roller, completecutting unit set--up
and adjustment sequence.
