Maintenance
Lubrication
Each cutting unit has (6) grease fittings (Figure 25) that must
be lubricated regularly with No. 2 General Purpose Lithium
Base Grease.
The lubrication points are front roller (2), rear roller (2) and
reel bearing (2).
Note:
Lubricating cutting units immediately after
washing helps purge water out of bearings and increases
bearing life.
1.
Wipe each grease fitting with a clean rag.
2.
Apply grease until clean grease is seen coming out of
roller seals and bearing relief valve.
3.
Wipe excess grease away.

Adjusting the Reel Bearings
To ensure long life of the reel bearings, periodically check if
reel end play exists. The reel bearings can be checked and
adjusted as follows:
1.
Loosen reel to bedknife contact by turning the bedknife
adjusting knobs (Figure 26) counterclockwise until no
contact exists.

2.
Using a rag or thickly padded glove, hold on to the reel
blade and try to move the reel assembly side to side
(Figure 27).

If end play exists, proceeded as follows:
A.
Loosen external set screw securing bearing
adjusting nut to bearing housing located on the
left side of the cutting unit (Figure 28).

Nut
B.
Using a 1-3/8inch socket wrench, slowly tighten
the reel bearing adjustment nut until no end
play of the reel exists. If adjusting nut does not
eliminate reel end play, replace reel bearings.
Note:
Reel bearings do not require preload. Over
tightening reel bearing adjuster nut will damage
reel bearings.
4.
Retighten set screw securing bearing adjusting nut to
bearing housing. Torque to 1.4-1.7 N-m (12-15 in-lb).
