Reel Assembly Installation (Fig. 26)
1. Thoroughly clean side plates and other cutting unit
components. Inspect side plates for wear or damage
and replace if needed.
Note: Check that grease seals on cutting reel shaft
are flush to 0.060” (1.5 mm) away from retaining ring on
reel shaft. If necessary, adjust position of grease seals
to allow proper clearance.

erly greased and positioned on cutting reel (see Reel
Assembly Service in this section). Apply thin coat of
grease to outside of grease seals and bearings on cut-
ting reel to ease reel installation. Also, apply grease to
bearing bores and threads in side plates.

unit parts can result in personal injury. Use
