The coupling between the drive shaft and the hub is ensured by mechanical interference.
Therefore, for safety reasons, replace the propeller hub each time it is disassembled.
Check that the propeller hub is correct for C115u (black-grey anodizing). Use of the C115p
propeller hub is dangerous for this model and involves a different assembly procedure.
Place the shaft on a stable support and carefully align the axis of the shaft and the piston of the
press.
