Preventing and managing internal spring cable crossing in 3A arms
22 years old. Gear and prices may have changed since.
What the thread found
- Cable crossing in 3A arms is a common issue that may not have a permanent solution and requires regular monitoring and adjustment
- Crossed cables can damage the plastic coating of cables and harm pulley wheels if neglected
- Cable crossing is often related to wear or inadequate lubrication of adjuster screws, which can become bent over time
- Applying adhesive between inserts and springs is unlikely to prevent cable crossing due to the high flex and forces involved in the spring mechanism
- Regular inspection is necessary to catch and correct cable misalignment before damage occurs
Depends on
- The suggestion to use adhesive was acknowledged as unlikely to work but was not tested
- Whether cable crossing reduces load capacity was raised as a question but not answered in the thread
- The discussion focused on 3A arms specifically and may not apply to other arm models
