Transition Drive Chain
Tension transition drive chain so there is 1/2 inch
deflection at A and B locations. Chain tension is
maintained on both the 60-pitch (A) and 80-pitch
(B) chains with idler sprockets. Both are located
on the right side of the transition.
Check that the sprockets are all in proper
alignment. Misalignment of these sprockets
will cause premature wear of the sprockets and
chain.
Transition Slip Clutch
The transition slip clutch is preset at the
factory so that damage will not occur to any of
the transition drive components; it cannot be
adjusted and will never require any adjustment.
Do not over tighten these sprockets or premature
chain and sprocket wear will occur.
In tough conditions if slip clutch is slipping
additional grease may be required.
Paddle Beater
The paddle beater has 3 adjustments to where it
can be extended or retracted depending on crop
conditions. To adjust move paddles to desired
slot (C). Make sure both paddles are adjusted
to the same slot.
