- Misalignment: The transmission and motor may not be properly aligned, causing the crank to bind and prevent it from turning. Check to make sure that the input shaft of the transmission is aligned with the output shaft of the motor.
- Damaged gears: The transmission is not getting connected to motor and gears may be damaged, preventing the crank from turning. Inspect the gears for any damage, such as chipped or broken teeth.
- Binding Components: There may be other components in the system, such as bearings or seals, that are binding and preventing the crank from turning. Check for any obstructions or tight spots that could be causing the issue.
- Incorrect Installation: The transmission and motor may not have been installed correctly, which could cause the crank to not turn. Double-check the installation instructions to make sure that everything is properly connected and secured.
- Miswiring: If the motor is not wired correctly, it may not be able to turn the crank. Check the wiring to ensure that it is properly connected according to the manufacturer's instructions.
If you are unable to resolve the issue yourself, it may be best to consult a professional mechanic or technician for further assistance.
