Inspection of Cutting Reel (Fig. 38)
1. Inspect reel bearings to insure that they spin freely
and have minimal axial play. The bearing balls must be
free of deformation and scoring.
2. Inspect the reel shaft as follows. If reel damage is de-
tected, replace reel.
A. Check the reel shaft for bending and distortion by
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).
3. Check the threaded inserts in the reel shaft for ex-
cessive wear or distortion. Replace inserts if damage is
evident.
A. The threaded inserts are installed with thread
locking compound (Loctite #243 or equivalent). One
insert has LH threads and the other RH threads. The
insert with LH threads has an identification groove on
the flange face. A groove on the reel shaft identifies
the reel end that has LH threads (see illustration in
Fig. 38).
B. To remove or install threaded spline inserts, use
correct spline insert tool (see Special Tools).
