Checking C-Shank Assembly Tightness

IMPORTANT: Sweep damage to tires may occur when using larger sweeps. Move standard or cut off part of sweep to prevent interference with a tire.

U-bolts must be tightened EVENLY, so standard is "square" on frame.

Loose hardware and/or broken brackets can result if all four contact points (A) are not touching frame when tightened.

1. Partially tighten U-bolt (B) top nut.

2. Tighten bottom U-bolt nut to specification.

Specification

U-Bolt -Torque 115 N·m (85 lb-ft)

3. Tighten top U-bolt nut to specification.

IMPORTANT: Check for correct tightness after 10 hours of use. Tighten to correct torque, if necessary.

NOTE: For deeper sweep penetration in wheel tracks, install sweep extender (C-shank only). (See INSTALLING SWEEP EXTENDER in this section.)

4. Check pivot bolt (C) for tightness, according to specification.
