SECTION 5 – OPERATING INSTRUCTIONS
Form 169149 Revision E 38
5.4 RADIAL PIN CLUTCH
(On all header drive shafts)
Every header is equipped with a driveshaft,
which contains a radial pin clutch. This clutch
emits a rattling sound and pulsating motion when
slippage occurs.
Radial Pin Clutch
The purpose of this clutch is to provide
protection against overload. When an obstruction
encounters the auger and creates an overload, the
clutch will slip notifying the operator of a
problem. Frequent slippage for more than two or
three seconds may result in clutch damage.
ATTENTION : Prolonged operation of the
header with the clutch slipping will cause
damage to the header and/or clutch.
5.5 DISCONNECTING FROM
COMBINE
ATTENTION : Always lock the storage
brace prior to disconnection. Failure to
lock storage braces will result in difficulty
reconnecting the header to the combine.
TIP: Engaged braces for long trips from
field to field on rough terrain will prevent
the pickup from bouncing.
a) Remove the clevis pins from storage
clevis.
b) Pull storage braces downward out of
storage brace holders and place in locking
position.
Storage Brace - Engaged
c) Reinstall the clevis pins in storage braces.
To ease pin installation it may be
necessary to slightly raise or push down
on pickup wheel.
d) Move unit to storage location.
e) Disconnect all hydraulics and wiring
between the header and combine. Some
combine models use a multi function
coupler that disconnects the hydraulics,
