6. Support deck with a floor jack or fork lift at
each end and position the deck pivot (M) in
to the linkage clevis (N). Make sure there is
a loose bushing inside the deck pivot.
7. Align the deck pivot with holes in clevis by
rising or lowering the floor jack and insert
shaft (P). At bottom install one regular hex
nut (H) and torque the nut to 250 ft-lbf. Then
install lock nut (G) and tighten against nut
(H).
IMPORTANT: Nuts need to have the proper
torque applied. Add grease to grease
zerk (R).
8. Attach turnbuckle (Q) from linkage to deck.
Use outer pivot (shown) if used with A-
Series Auger or D-Series Draper Header
and use inner pivot if used with an R-Series
Disc Header.
9. Adjust turnbuckle (Q) length so the deck is
approximately 4 in. (100 mm) from the right
hand drive tire. The turnbuckle length should
be about 21 in. (530 mm) long for the R-
Series Disc Header and 25 in. (630 mm)
long for the A-Series Auger or D-Series
Draper Headers.
NOTE: The lift cylinder is single acting and it
is pressurized with the draper drive circuit.
Therefore when the deck is setup for the R-
Series Disc Header the windrower needs to
be running for the deck to be in its most
forward position. This adjustment can be
fine-tuned when the hydraulics setup is
complete.
10. Raise backsheet (R) on deck and remove
two top nuts (T) and (U). Install gas shock
(S) in center hole and secure with nuts (U)
and (T). Make sure taper of nut (U) is facing
the gas shock rod end as shown.
