Service Crankshaft for 56SR Engines YSS2011 - YS Engine  [YSS2011]

This YS Engine YSS2011 crankshaft is supplied as a service replacement for 56SR model engines. It forms the rotating core of the engine assembly and is provided as a single spare intended for repair, maintenance, and tuning of hobby RC engines.

Service pointers: make sure the engine bears the 56SR mark before purchasing, inspect seals and bearings while dismantling, and keep all parts free from contamination when rebuilding. The part is for model engine use only and not suitable for full-size vehicles.

Typical installation involves removing the engine rear cover and crankcase halves to access the connecting rod and timing components, then installing the crankshaft with care to bearing alignment. Seek a specialist if you are not experienced in model engine strip-down.
