Adapter Mounting Instructions

for Case IH 60, 77 & 80 Series 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

coupler plate assembly:

Reel Drive – Yellow to Yellow and White to White.

Reel Lift – Black to Black

• 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).

• Match the coloured cable ties to connect hoses for Reel Fore-

Aft/Header Tilt – Red to Red and Green to Green.

WARNING: For headers with hydraulic reel fore-aft, never connect the two fore-aft couplers

to each other. This would complete the circuit and allow the reel to creep forward in

transport, resulting in instability. The reel lift line (black cable tie) can be connected to the

reel fore aft coupler (red cable tie) for storage. Cap the other reel fore-aft hose coupler.

• After attaching to combine, reposition hoses in clamps for best fit-up to combine connection points.
