How to Replace the Crankshaft Bearings on a Derbi Senda

Model: Derbi Senda 125
Part: Bearing

Video tutorial

To replace the crankshaft bearings on a Derbi Senda, completely remove the engine block from its housing by unscrewing the bolts that secure it to the supports and disconnecting the connectors. Next, unscrew the bolts that secure the cylinder, removing it from the top and accessing the piston underneath.

This must be removed from the conrod by expanding the corresponding ring and then detaching the conrod from the crankshaft. Using a puller, the old bearings can be removed and replaced with new spare parts.
