WEAR PLATES:

The wear plates must line up with each other to give the knife back a straight bearing along its entire

length. Wear plates should project approximately 1/16" in front of the leading edge of the cutterbar after

adjustment. Triumph wear plates are hardened on both edges. After the first edge has worn back,

simply turn over the plate to obtain a new wearing surface. See Fig. #14 & #15, page #18.

CLIPS:

After all guards are adjusted, it is necessary to see that the knife clips are bent down to within 1/64" of

the section. The easiest way to check this is to hold the knife down on the ledger plate and use a feeler

gauge or the cover of a matchbook to measure the clearance. Do not attempt to hold the knife tightly

against the ledger plate with the clips. Knock the clips down with a hammer. A light blow is all that is

required. If the clips drag on the knife, pry them up. Drag will bind the knife and wear out the clip very

rapidly. See Fig. #16 & #17.

KNIFE HEAD CAPS: (2500-3500 Models)

The proper clearance between the front and rear knife head caps and new knife head is set at the

factory. As the caps and knife head wear, shims should be removed to maintain this clearance. Save

these shims to be used with new knife or knife head. The clearance should be just enough to permit the

knife to work without binding. Too much clearance will cause plugging and pitman vibration. Refer to

the CUTTERBAR ASSEMBLY illustration in the parts list pages, covering these parts.
