Common Redcat RER13642 Problems and Troubleshooting

Wheel wobble, stripped hexes, or lost pins on your VOLCANO-16? Learn the real causes of RER13642 problems and when to replace the set.
Quick Answer
Most RER13642 problems come from a pin that has sheared, fallen out, or worn the wheel hex. Replace the missing pin and inspect the hex for damage; if the hex is rounded, replace the hub or wheel before installing a new pin.
Why the Pin Fails Before the Hex Does
A wheel hex pin is the small steel dowel that locks the wheel hex to the axle. It is designed to be the weak link: when the wheel takes a hard hit or the nut is over-tightened, the pin should shear or back out instead of stripping the axle or hex. That is why a single lost pin often shows up as a wheel that spins freely or wobbles, not as a broken axle.
The RER13642 set gives you eight pins for the VOLCANO-16, so you can replace a failed pin and keep spares. If you keep losing the same pin, the problem is usually the hex or the wheel, not the pin itself.
When the Hex or Wheel Is the Real Problem
If a new pin fits loosely or the wheel still rocks after installation, the hex slot has likely rounded out. A worn hex will eat through replacement pins quickly. In that case, no pin set will fix the issue; you need to replace the wheel hex or the wheel hub.
Check the axle shaft for burrs or a worn flat spot where the pin seats. A damaged axle will keep damaging pins even after you install a fresh RER13642 pin.
Symptom-to-Solution Diagnosis
- Wheel wobbles or spins freely: Inspect the pin: if it is missing or sheared, install a new pin from the RER13642 set. If the pin is intact, check the hex for rounding. A missing pin is a five-minute fix; a rounded hex is not.
- Pin keeps falling out: Check that the wheel nut is tight and the hex is not worn. If the pin falls out with a new hex, inspect the axle for damage. Repeated pin loss points to a worn hex or axle, not the pin.
- New pin fits loosely: The hex slot is likely rounded. Replace the wheel hex or wheel hub before installing another pin. Stop replacing pins if the hex is damaged; fix the hex first.
- Axle has burrs or a worn flat spot: Replace the axle shaft. A damaged axle will continue to shear pins even with a new hex. If the axle is damaged, no pin set will solve the problem.
Product Facts
- RER13642: RER13642 is a set of eight wheel hex pins listed as spare parts for the VOLCANO-16. Having eight pins means you can replace a failed pin and keep spares for the next repair, but it does not include the hex or wheel if those are worn.
