Why Your eitech Gear Slips and How to Fix It

Diagnose why an eitech gear slips in your model and apply the right fix, from tightening the hex socket to replacing a worn gear.
Quick answer
Your eitech gear usually slips because the hex socket is loose on the shaft or the gear teeth are worn. Tighten the fixing screw or replace the gear if the teeth are damaged.
Why gears slip: common causes
A slipping gear often results from a loose fit between the gear's hex socket and the shaft, or from worn teeth that no longer mesh cleanly. In eitech models, the hex socket is designed to grip the shaft firmly, but over time the fixing screw can back out, especially under load.
Another cause is misalignment: if the gear is mounted at an angle or the shaft is bent, the teeth engage unevenly and can jump. Check the shaft and the gear's seating before assuming the gear itself is faulty.
When to replace instead of repair
If the gear teeth are visibly worn, chipped, or rounded, no amount of tightening will restore proper meshing. In that case, replacing the gear is the reliable fix. The eitech Gear 60 teeth module 1 hexagon socket is a standard component, so you can swap it without modifying your build.
Diagnosis and fix steps
- Symptom: The gear loses contact with the mating gear under load, causing a clicking or skipping motion. Confirm the slip happens only under load, not when turning by hand.
- Likely cause: The hex socket is loose on the shaft, or the gear teeth are worn or misaligned. Inspect the gear teeth for wear and check the shaft for bends.
- Corrective action: Tighten the fixing screw on the hex socket to secure the gear to the shaft. If the teeth are damaged, replace the gear with a new eitech gear 60 teeth module 1 hexagon socket. After tightening, test the gear under load; if it still slips, replacement is the next step.
- Stop or choose another option: If the gear still slips after tightening and the teeth look fine, the shaft may be worn or the mating gear may be the issue. Stop forcing it and inspect the entire drivetrain before ordering parts. Check the shaft and mating gear before buying a replacement.
Gear options
- Gear 60 teeth module 1 hexagon socket: The eitech Gear 60 teeth module 1 hexagon socket is a 60-tooth gear with module 1 spec and a hexagon socket, part of the eitech Manufaktur line. Its hexagon socket ensures a secure grip on the shaft, reducing the chance of slipping if properly tightened.
