20.9.4 - Set Knifehead Bearing
Assembly Fore/Aft Position
1. Check the clearance between the knife and
the guards at the locations shown below.
1/32” to 1/16”
(1 - 2 mm)
Fig. 176 - Knife/Guard Clearance
2.
If adjustment is required, proceed with the
following steps:
3.
Disconnect the drive shaft PTO from the
knife drive system to allow you to move the
knives freely while aligning.
4.
Remove the shield covering the flywheel.
5.
Run a 1/2” (1.27 cm) bolt or rod through the
alignment hole of the two flywheels to keep
them aligned with each other.
Fig. 177 - Align Flywheels with a Bolt
6. Remove the feather plate from above the
two knife heads on the cutter bar.
7. Start installing shims between the
gooseneck and bell crank and watch for
clearance between the knife assembly
(knifeback on top) and guards. Install
enough shims so that the clearance between
the knife assembly (knifeback on top) and
the center guards is roughly 1/32” to 1/16”.

8. Once fore/aft position of knife head bearing
assembly is set, tighten mounting bolts to
170 ft-lbs.
9. To prevent binding between the left and
right knife at the overlap and/or excessive
wear caused by the sickle sections pressure
onto the guards, check clearances between
the sickle sections and the guards and also
between the left hand and right hand knives
at the overlap. If excessive pressure is found
please readjust vertical position of knifehead
bearing assemblies. Also over greasing of
the knifehead bearings can cause excessive
pressure. To relieve grease pressure in the
knifehead bearings depress the check-ball in
the grease fittings.
