19 years old. Gear and prices may have changed since.
What the thread found
- A displaced collar on the spring assembly can scratch against surrounding components and cause clicking sounds during boom movement.
- A curved or deformed spring may result from the arm operating with a misaligned collar causing excessive compression.
- A Master arm of this type typically has a lifting capacity between 40 and 65 pounds, with a payload capacity of 20 to 45 pounds when used with a 20-pound camera sled.
- Inspection and repair of a displaced collar should be performed by an experienced technician at a specialized service center.
- Additional inspection of springs, cables, and other components is recommended when an arm shows signs of having been operated in a damaged state.
Depends on

- No definitive diagnosis is possible from photographs alone without physical inspection.
- The exact cost of repair is not provided.
- The age and overall condition of the arm is unknown.
