DPA Cutting Units: Service and Repairs
Note: The reel nut on the left end of the cutting reel has a black finish and
has left-hand threads. The left end of the cutting reel shaft is identified with a
groove cut just inside of the left-most reel spider. Tighten the reel nuts to the
specified torque once the cutting reel is installed in the cutting unit.
5. Install the reel nuts finger tight.
1. Position the cutting unit on a flat work area.
Contact with the reel, bedknife or other cutting unit parts can result
in personal injury. Use heavy gloves when installing the cutting reel.
2. Apply a thin coat of grease to the outside of the cutting reel bearings and
carefully slide the cutting reel assembly into the right side plate. Make sure
that the reel bearing is fully seated in the right side plate, and that the real nut
on the left (exposed) end of the cutting reel has a black finish.
3. Place the flat wire spring into bearing bore of left side plate and carefully
slide the left side plate onto the cutting reel assembly as far as possible.
4. Install the shoulder bolts and flange nuts that secure the left side plate to
the cutting unit frame. Tighten the shoulder bolts from 24 to 27 N∙m (18
to 20 ft-lb).
5. If the reel nuts were loosened during cutting reel service, put a block of wood
between the cutting reel blades to prevent the reel from rotating and tighten
the reel nuts from 123 to 149 N∙m (90 to 110 ft-lb). Fill the reel nut splines
with high temp Mobil XHP−222 grease or equivalent.
