Quick answer
Most Redcat Part 13823 issues stem from stripped threads, binding, or worn linkage ends. Inspect the part first, then apply the matching fix—or replace it with a fresh pair if damage is beyond repair.
Why the 68.5 mm length matters
The Redcat Part 13823 servo linkage is precisely 68.5 mm long. If you install a different length, you can introduce steering bind or reduce steering throw. Always verify the linkage length before installation, especially if you are replacing a damaged part.
Because this part comes as a pair, you have a spare ready. That spare is useful for quick field repairs, but it also means you can compare the old and new linkages to spot wear or bending that might not be obvious at first.
When to replace instead of repair
If the linkage is bent, cracked, or has stripped threads, repair is not practical. The metal is thin and not designed to be straightened. In those cases, replacing the part with a new pair is the safer and quicker option.
If the issue is only a loose screw or a misaligned ball joint, you can often fix it without replacing the part. Knowing the difference saves you time and money.
Diagnosis and fix guide
- Symptom: Steering feels loose or has excessive play: Check the ball joints and screw holes on the linkage. If the hole is stripped or the ball joint is worn, the link will not hold securely. If the hole is stripped, replacement is the only reliable fix.
- Symptom: Steering binds or sticks: Inspect the linkage for bends or debris. Verify the length is exactly 68.5 mm. A bent link can cause binding at the servo or steering arm. If the link is bent, do not try to straighten it—replace it.
- Symptom: Linkage pops off during driving: Check that the screw is tight and the ball joint is fully seated. If the screw keeps loosening, apply thread lock and re-tighten. If the screw hole is stripped, the part must be replaced.
- When to stop and choose another option: If the linkage is cracked, bent, or stripped, stop attempting repairs. Replace it with a new pair, such as Redcat Part 13823, to restore proper steering. Always keep a spare linkage in your toolkit for quick swaps.
