Part: Engine

Video tutorial

To dismantle the engine of the TM Racing 125, first extract the engine from its housing: this can be done by unscrewing the bolts that secure it to the supports. Once the bolts are loosened, you can slide the engine out of its seat and proceed to loosen the bolts that secure the cylinder: the latter can be removed from the top of the engine by widening the retaining ring that secures the piston inside.

By disconnecting the piston from the connecting rod, you can separate the two lower crankcase halves, replacing all necessary components inside.
