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 in cylinder kit)
matching the type on your combine to end of
hoses.
NOTE: Coupler completion kits are available for
each combine. See completion kit numbers in
illustration below.
Use the O-ring (A) (provided in cylinder kit) on the
3/8 tube thread of the selected adapter fitting.
This connects into shut-off valve for proper seal.
2) Attach cylinder assembly as follows:
a) Orient cylinder with hoses routed towards header.
b) Attach cylinder to adapter with 1-inch dia. clevis pin (B) and lynch pin.
c) With adapter connected to combine, connect couplers to combine hydraulics.
d) Drive combine close enough to header and extend or retract cylinder to allow attaching cylinder to
header with 1-inch dia. clevis pin (C) and lynch pin.
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.
