What the thread found

• The Archer 1 can develop unwanted play in the yoke bearing axis between the gimbal and yoke fork that causes the rig to shift out of level when tilted past certain angles.
• Thin shims inserted between the yoke and gimbal on the appropriate sides can be used to eliminate the play and restore acceptable centering, following the Ultra gimbal centering manual procedure.
• Multiple shims of varying thickness may be needed to achieve proper alignment, requiring iterative testing and adjustment.
• A quick shimming solution may restore functionality for immediate use but may not represent a permanent fix, and professional factory service is recommended for complete resolution.
• Keeping spare shims in the kit allows for emergency adjustments on set if misalignment occurs.

Depends on

• This is specific to the Archer 1 model, which lacks adjusting screws on the yoke present on later models like the Archer 2 and Ultra 2.
• The solution represents a temporary workaround rather than a definitive repair.
• The procedure requires access to shims and the Ultra gimbal centering manual, and successful alignment depends on careful trial and error with different shim combinations.
• The user notes the outcome was acceptable but not perfect.
