ASSEMBLY
ATTACH CENTER LINK
For mechanical center link (G), attach to adapter frame
with clevis and lynch pins as shown, with locking collar
(H) forward and pointing upward.
For hydraulic center link:
1) Attach quick-couplers (not included) matching the
type on your combine to end of hoses. Adapter
fittings are included in kit to allow installation of
quick couplers on hoses. Use the O-ring (A)
(provided in kit) on the 3/8 tube of the selected
adapter fitting. This connects into shut-off valve for
proper seal.
2) Attach cylinder assembly as follows:
a) Attach larger clevis end of cylinder to adapter
with 1-inch dia. clevis pin and lynch pin at (C).
Remove the 5/8” clevis pin and lynch pin at
(D).
b) With adapter connected to combine, connect
couplers to combine hydraulics.
c) Drive combine close enough to header and
extend or retract cylinder to allow attaching
cylinder to header with 1-inch dia. clevis pin
and lynch pin at (B).
d) Once header is fully raised, and combine
lift cylinder stops engaged, install 5/8”
clevis pin and lynch pin at (D).
e) Route hoses along header tube and secure
with clamp (F), using 3/8 x 3/4 carriage bolt
and nut for 962 header and 3/8 x 5/8
thread rolling screw for 972 header.
3) When detaching adapter from combine, before
disconnecting quick couplers, turn off oil flow at
shut-off valve (E). This allows easier
reattachment of couplers at combine.
Remember to restore oil flow at shut-off valve
before next use.
