Adjusting Rear Axle

The axle is adjustable to let the rear tires track the drive tires.

CAUTION: When changing axle widths, the rear frame of combine must be raised and blocked properly.

Jack up one end of the axle (A). Remove bolts (B), (C), cylinder bolts (D) and tie rod bolts (E).

Loosen power steering hose clamps (F) to adjust hoses. Extra hose must be stored in axle frame. Tighten clamps after moving hoses.

If combine is equipped with 4-wheel drive, loosen hose clamp (G) and hose tie strap (H). Pull enough hose through clamp to be able to reposition axle. Tighten clamp and tie strap after moving axle.

Refer to the chart and position axle to correct width. Tie rod holes will go in or out the same amount of holes and align correctly.

A drift may be needed to align axle holes and start upper bolts (C). Place bolts (B), (C), (D) and (E) back in correct holes.

Torque cap screws (B), (C) and (D) to 620 N·m (460 lb-ft).

Repeat steps on other side.

IMPORTANT: This sequence must be followed because of "relaxing" of the bolts.

Retorque first side to 620 N·m (460 lb-ft), then retorque second side to 620 N·m (460 lb-ft).

NOTE: For minumum tread width with chopper installed, refer to charts on following pages.
