Installing the Cutting Unit Assembly
1. Clean the side plates and other cutting unit components. Inspect the side
plates and pitch arms for wear or damage and replace the components
if necessary.
2. Ensure that the flocked seals, reel bearings, bearing lock screw, and reel
driveshaft are properly positioned on the cutting unit; refer to
Cutting Unit Assembly (page 7–31)
.
CAUTION
Contact with the reel, bedknife or other cutting unit parts can result
in personal injury.
Use heavy gloves when handling the bedbar.
3. Position the cutting unit on a flat work area. The rollers, bedbar, and cutting
unit crossmember should be attached to the left side plate. Ensure that the
left pitch arm (item 16 in
) and compression spring are fitted
to the left side plate.
4. Place the flat wire spring into the bearing bore of the left side plate. Carefully
slide the cutting unit assembly (with the flocked seals, reel bearings, bearing
lock screw, and reel driveshaft) into the left side plate. Ensure that the
bearing is fully seated into the side plate.
5. Carefully slide the right side plate with the right pitch arm (item 2 in
) and compression spring onto the cutting unit assembly, front roller and
rear roller. Ensure that the side plate is fully seated onto bearing on the
reel shaft.
6. Install the shoulder bolts (item 8 in
) and flange nuts to secure
the right side plate to the crossmember; torque the shoulder bolts to
24 to
27 N∙m (210 to 240 in-lb)
.
IMPORTANT
If the reel driveshaft (item 5 in
) is to be tightened, use
appropriate wrench or socket on 1 inch hex surface of shaft. Do
not use 1/2 inch extension on the end of the reel driveshaft when
loosening or tightening the driveshaft. The 1/2 inch hex is intended
for backlapping only.
7. If the bearing locknut (right-hand threads) and reel driveshaft (left-hand
threads) were loosened during the cutting unit service, put a block of wood
between the cutting unit blades to prevent the reel from rotating. Torque the
bearing locknut (right-hand threads) and reel driveshaft (left-hand threads)
from
123 to 149 N∙m (90 to 110 ft-lb)
(
).
8. Secure the bedbar assembly to the right side plate; refer to
. Ensure that the plastic and steel washers are properly
positioned.
9. Secure the front and rear rollers to the right side plate; refer to
Front Roller (page 7–19)
and
Installing the Rear Roller (page 7–21)
.
10. Adjust the cutting unit; refer to the
Cutting Unit Operator's Manual
