Adapter Mounting Instructions

for Lexion Combines

PREPARING THE HEADER

1. Attach the hydraulic/electrical completion package as follows:

• Mount the coupler bracket provided with the adapter to the inboard flange of the

left header leg with two 1/2 x 1 inch carriage bolts and flange nuts at (A). (For 963

Header, coupler bracket bolts to a bracket welded to the header back tube near left

side of opening.)

• Attach brace (D) to coupler bracket (F) using 1/2 x 1 inch carriage bolt and flange

nut at (G). Ensure brace (D) is tight against backtube and bottom of coupler

bracket. Tighten bolt (E) and jam nut after tightening brace to coupler bracket. Bolt

(E) should be tight enough to ensure L/H leg of brace is tight against backtube.

• Match the coloured cable ties to connect the header hoses to the multi-link coupler:

Reel Drive – Yellow to Yellow and White to White.

Reel Lift – Black to Black

NOTE: Loosen clamp (C) hardware and remove couplers from underneath (as

shipped). Extend hoses and clamp hoses under clamp (C) as shown.

• Mount the Reel Fore-Aft/Header Tilt selector valve (if equipped) to the coupler

bracket with two 1/4 x 2-1/2 inch hex bolts and nuts at (B).

• Replace straight hydraulic fitting attached to green cable tied hose at front of block

with 45º hydraulic fitting supplied with selector valve.

• Match the coloured cable ties to connect hoses for Reel Fore-Aft/Header Tilt – Red to Red and Green to

Green, on the multi link connector.

NOTE: Depending on year of manufacture of your combine, it may be necessary to switch reel drive

couplers (yellow & white) to prevent reel turning backward. Also, reel fore-aft hoses (red & green) may

need to be switched for proper operation.

2. Prepare sickle drive as follows:

963 Headers only: Replace the existing sickle drive

belt with belt provided with adapter.

972/973/974 Headers: Move idler (G) to raised

position shown. Belt provided with adapter is not
used. Move nut (H) on idler adjusting bolt to lower
position shown
