MAINTENANCE/SERVICE
SICKLE AND SICKLE DRIVE (continued)
Wobble Box Maintenance
Mounting Bolts - Check four wobble box
mounting bolts (B) torque after the first 10 hours
operation and every 100 hours thereafter. Torque
should be 200 ft.lbs. (270 N
⋅
m). When tightening,
start with the side mounting bolts.
Lubricant - Check wobble box lubricant level
before first operation and every 100 hours
thereafter. To check:
1. Raise header to a point where the wobble box
base is approximately level.
2. Remove breather/dipstick (A). Oil level must
be between end of dipstick and bottom hole (or
groove) in dipstick.
3. Add as required. See "Recommended Lubri-
cants" for specified gear lube and capacity of
box.
4. Replace breather/dipstick.
Change wobble box lubricant after the first 50
hours operation and every 1000 hours (or 3 years)
thereafter.
To drain wobble box, raise header fully and
engage header lift cylinder stops. Remove
breather/dipstick (A) and drain plug (D).
Assembly/Disassembly
If removing wobble box pulley, a 3-jaw puller is
recommended.
When reinstalling drive arm or pulley:
1. Remove any rust or paint from inner spline. For
replacement parts, remove oil/grease with
degreasing agent.
2. Before assembly, apply Loctite® #243 adhesive
(or equivalent) to spline. Apply in two bands (C)
as shown, with one band at end of spline and
one band approximately mid-way.
