J&M 4WS Front and Rear Axle Alignment Owner's Manual

Adjusting Push-Pull Rod to Align Front and Rear Axles
Before initial operation of header transport, follow these steps to align front and rear wheels while under load:
1. With the transport empty, loosen both nuts on the push-pull rod. The push-pull rod is left hand threaded on
one end and right hand threaded on the other end to adjust alignment like a turnbuckle. One of the nuts is
pictured in blue in the diagram below.
2. Place combine header on transport.
3. Drive the loaded transport in a straight line on level ground to check alignment.
4. Adjust push-pull rod by rotating the main rod body.
5. Repeat steps 3 and 4 until the transport rear wheels are aligned with front wheels.
6. Remove combine header from transport.
7. With the transport empty, tighten both nuts on the push-pull rod.
8. Return the combine header to the transport.
9. With the nuts on the push-pull rod tightened, drive loaded transport in a straight line on level ground to
confirm alignment.
