REPLACEMENT
1. Do the removal procedure in reverse order.
The new brake/steer caster could have 2 or 4 bolt holes in the stem. If the stem has a green dot on it, the
green dot is toward the head end of the bed during installation.
2. Make sure the caster (C) rolls and swivels freely, and that all brake and steer functions operate
correctly.
The brake/steer casters with the green dot will lock in the trailing position only.
BRAKE AND STEER CASTER ADJUSTMENT
1. Set the brake/steer pedal to the neutral position.
2. Do Step 1 through Step 5 of “Removal” on page 4-51.
3. Turn the setscrew (D) clockwise while you turn the caster (C) approximately 2" (approximately 50
mm) from side to side, until you hear a light ratcheting sound.
4. Turn the setscrew (D) counterclockwise until the ratcheting stops.
5. Set the brake/steer pedal to the brake position.
6. Make sure the caster (C) tire does not roll.
7. If the caster (C) tire rolls, tighten the setscrew (D) slightly.
