Installation (Fig. 32 & 33)
1. Thoroughly clean side plates and other cutting unit
components. Inspect side plates for wear or damage
and replace if needed.
2. Make sure that grease seals and bearings are prop-
erly installed on cutting reel (see Reel Assembly Service
in this Chapter).
3. Cutting unit serial nos. 315000001 & Up have
O−rings in the reel bearing bore of each side plate. Make
sure the O−rings are in good condition and properly in-
stalled in the side plates.
4. Apply a thin coat of antiseize lubricant to the reel
bearing bore of each side plate (Fig. 34).

move flange head screw and position shim(s) between
carrier frame and side plate so that clearance is less
than 0.065” (1.6 mm). Make sure that the carrier frame
pivots freely after assembly.
9. Install cap screw and flat washer that secure rear
