Insert studs (A) into the spindle as shown.
NOTE:
Plugs are factory-installed as shown in position (B), but may
come loose over time. Ensure the studs are inserted into
the proper locations.
IMPORTANT:
Ensure clockwise spindles rotate clockwise and
counterclockwise spindles (with machined grooves) rotate
counterclockwise.
IMPORTANT:
The offset gear design makes it possible to install spindles
that rotate in the wrong direction. If the spindles rotate in
the wrong direction, the discs will not spin up after impact,
potentially damaging cutterbar components.

Check and adjust disc timing as follows:
NOTE:
There are an odd number of teeth on the cutterbar gears
which can make spindle hub alignment difficult.
a.
Place one end of disc timing tool (A) on adjacent
disc (B) and the other end on left spindle as shown.
b.
Check bolt hole alignment (C) as shown.
c.
If alignment is slightly off, lift spindle and rotate it one
tooth in either direction to try and line up bolt holes.
d.
Recheck with disc timing tool, if still not lining up, lift
spindle and rotate hub 1/4 turn at a time, and recheck
again with disc timing tool.
e.
Repeat until bolts are aligned.
NOTE:
Arrow points to the front of disc header.
