previous page.
1. Remove chain hooks and move lifting vehicle
to rear of header. Attach chain to center link
anchor on frame tube and raise rear of header.
NOTE: Remove header stands from header outer
legs. These stands are not used with gauge
wheels.
2. Identify right and left wheel supports: Left
wheel support has single wheel caster, right
wheel support is attached to dual wheel beam.
3. Front end of gauge wheel spring assembly
was attached to header outer legs before

clevis at other end of spring to plate (C) at left

NOTE: Do not collapse clevis by over-tightening
hardware. Clevis must be free to rotate.
NOTE: For ease of installing right wheel support,
remove 1/2 inch bolt (H, next page) securing pivot
