Maintenance

Lubricating the Cutting Unit

Each cutting unit has 6 grease fittings
be lubricated regularly with No. 2 lithium grease.
The lubrication points include the front roller (2), the rear
roller (2), and the reel bearing (2).
1. Wipe each grease fitting with a clean rag.
2. Apply grease until clean grease comes out of the roller
seals and the bearing relief valve.
3. Wipe any excess grease away.

Adjusting the Reel Bearings

To ensure long life of the reel bearings, periodically check
if reel end play exists. You can check and adjust the reel
bearings as follows:
1. Loosen the reel-to-bedknife contact by turning the
bedknife adjusting knobs
until no contact exists.

2. Using a rag or a thickly padded glove, hold on to the
reel blade and try to move the reel assembly side to
side (Figure 31).
3. If end play exists, proceeded as follows:
A. Loosen the external setscrew securing the bearing
adjuster nut to bearing housing located on the left
side of the cutting unit
1. Setscrew
B. Using a 1-3/8 inch socket wrench, slowly tighten
the reel-bearing adjustment nut until no end play
of the reel exists. If adjusting the nut does not
eliminate reel end play, replace the reel bearings.
Note: The reel bearings do not require preload.
Overtightening the reel-bearing adjuster nut will
damage the reel bearings.
4. Tighten the setscrew securing the bearing adjuster nut
to the bearing housing.
Note: Torque the nut to 1.4 to 1.7 N∙m (12 to 15
in-lb).
