What the thread found

• The internal arm post pin in G-50 rigs can suddenly snap during use, creating a loud cracking sound but potentially allowing the operator to catch the rig and prevent equipment from falling.
• Early G-50 units with this vulnerability were retrofitted by the manufacturer with thicker internal arm post pins as a free upgrade.
• A paid upgrade kit became available that uses a different design with a removable post, allowing for quick changes and the use of longer posts on the G-50.
• Operators who purchased G-50 arms around 2006 may have been missed during the initial free upgrade rollout depending on their regional dealer.
• The PRO arm has an arm post with specific holes for safety pins and mounting screws, and using these holes incorrectly can create unsafe conditions.

Depends on

• The discussion focuses on specific models from around 2006-2008 and may not apply to current production.
• Warranty coverage and replacement policies appear to have varied by region and dealer.
• The exact failure mechanism and frequency of the pin snapping is not comprehensively documented in the thread.
