Disassembly of Cutting Reel (Fig. 24)
1. Remove bearing lock screw (item 5) and reel nut
(item 6) from cutting reel. Reel nut has LH threads and
is in end of reel shaft identified with a groove that is just
inside of reel spider (Fig. 25).
2. Slide bearings from reel shaft.
3. Note orientation of flocked seals for assembly pur-
poses. Remove seals from reel shaft.
Inspection of Cutting Reel (Fig. 24)
1. Inspect reel bearings to insure that they spin freely
and have minimal axial play.
2. Inspectthereelshaftasfollows.Ifreeldamageisde-
tected, replace reel.
A. Checkthereelshaftforbendinganddistortionby
placing the shaft ends in V--blocks.
B. Check the reel blades for bending or cracking.
C. Check the service limit of the reel diameter (see
Preparing a Reel for Grinding in this section).
D. Check threads in ends of reel shaft.
3. Check the splines in the reel nut (item 6) for exces-
sivewearordistortion.Replacereelnutifdamageisevi-

Assembly of Cutting Reel (Fig. 24)
1. If bearings and/or flocked seals were r emoved from
reel shaft, discard removed components and replace.
IMPORTANT: The flocked seal should be installed
so the flocked side of the seal is toward the bearing
location.
2. Slide flocked seals (flocked side orientated toward
bearing location) and bearings fully onto reel shaft.
Bearings and seals should bottom on reel shaft shoul-
der.
3. Install bearing lock screw (item 5) and reel nut (item
6) into reel shaft to s ecure bearings. Reel nut has LH
threadsandshouldbeinstalledinendofreelshaftiden-
tified with a groove that is just inside of reel spider (Fig.
25).
NOTE: Installation torque for bearing lock screw and
reel nut is from 90 to 110 ft--lb (123 to 149 N--m).Itis
easiest to torque these items after the cutting reel is
installed in the cutting unit frame (see Reel Assembly
Removal and Installation in this section).
4. Thoroughly fillsplineareaofreel nut(left sideof cut-
ting reel) with grease.
