This demonstration guide answers one field question about salt-seized rotation ring or a stretched cable. Measurements come before parts, and the notes are not a generic equipment FAQ.
Diagnose before replacing parts
Start with ring free play and cable travel. That reading separates salt-seized rotation ring or a stretched cable from adjacent faults that share the same complaint.
If the measurement is out of spec, treat the rotation ring as the primary path. If it is in spec, do not replace the rotation ring just to complete a parts list.
Repair the failed system
The usual correction is the rotation ring, installed to the documented spec for this complaint.
A demonstration shop records the finding so the next technician is not repeating a guess about salt-seized rotation ring or a stretched cable.
Stop before you make it worse
Do not forcing rotation with a wrench on plastic gears. That shortcut hides the original measurement and creates a second failure.
If the machine still fails after the rotation ring is corrected, convert the visit to a broader diagnosis rather than stacking parts.
