Slip Clutch Adjustment - Woods BW10.52 Operator's Manual

Blade Installation (Figure 6)
CAUTION
■ Your dealer can supply genuine replacement
blades. Substitute blades may not meet orig-
inal equipment specifications and may be
dangerous.
■ Crossbar rotation has clockwise rotation on left
gearbox and counterclockwise rotation on the
right and center gearboxes when looking down
on cutter. Be sure to install blade cutting edge to
lead in correct rotation.
■ Make sure that blade offset is oriented down-
ward and that each blade freely swings all the
way around when installed.
NOTE: Always replace or sharpen both blades at
the same time.
1. Inspect blade pin (6) for nicks or gouges, and if you
find any replace the blade pin.
2. Insert blade pin (6) through the blade (5). Blade
should swivel on blade pin; if it doesn't, determine
the cause and correct.
3. Align crossbar (4) with blade access hole in cutter
frame. Make sure blade offset is down away from
cutter.
4. Insert blade pin (6) through blade (5). Apply an-
ti-sieze compound to the blade pin and push through
crossbar (4).
5. Assemble keyhole plate (3) into groove in blade pin
(6).
6. Align keyhole plate (3) to tapped hole in crossbar
(4) and assemble blade pin lock clip (2) into groove
in blade pin (6).
7. Secure blade pin lock clip (2) with bolt (1). Torque
bolt to 85 lbs-ft.
NOTE: Blade should be snug but should swivel on
pin without having to exert excessive force. Blade
should not move more than a 1/4 inch up or down at
the tip. Shims are available to compensate for wear
as needed. Use #10520RP - Blade Shim, .048" and
#13946RP - Blade Shim, .036" as needed.
8. Grease pin via zerk at end of pin.
9. Repeat steps for opposite side.

Blade Sharpening
NOTICE
■ When sharpening blades, grind the same
amount on each blade to maintain balance.
Replace blades in pairs. Unbalanced blades will
cause excessive vibration, which can damage
gearbox bearings. Vibration may also cause
structural cracks to cutter.
■ Do not handle blades with bare hands. Wear
gloves. Careless or improper handling may re-
sult in injury.
1. Sharpen both blades at the same time to maintain
balance. Follow original sharpening pattern.
2. Do not sharpen blade to a razor edge—leave at
least a 1/16" blunt edge.
3. Do not sharpen back side of blade.
Follow Original Pattern

SLIP CLUTCH ADJUSTMENT

BW10.52 & BW15.52 (FIGURE 8)
The slip clutch is designed to slip so that the gear-
box and driveline are protected if the cutter strikes an
obstruction.
A new slip clutch or one that has been in storage over
the winter may seize. Before operating the cutter, make
sure it will slip by performing the following operation:
1. Turn off tractor engine and remove key.
2. Remove driveline from tractor PTO.
3. Access the spindle drivelines by raising the center
gearbox shield.
4. Loosen six 10 mm cap screws (6) to remove all ten-
sion from Belleville spring plate (5).
5. Hold clutch hub (3) solid and turn shaft to make sure
clutch slips.
6. If clutch does not slip freely, disassemble and clean
the thrust plate faces (4), flange yoke (1), and clutch
hub (3).
7. Reassemble clutch.
