YS Engine YSS2011 56SR Crankshaft Replacement for Hobby Engines  [YSS2011]

The YS Engine YSS2011 crankshaft is produced as a spare part for the 56SR series of model engines. It operates as the rotating core within the engine and is provided as a single item for maintenance, repair, and tuning tasks on RC model powerplants.

Key service advice: check the engine's stamped identifier to ensure it is a 56SR before ordering, examine bearings and seals when removing the old crank, and maintain cleanliness during reassembly to prevent debris contamination. This component is intended only for hobby model engines.

Fitting the crank generally needs standard disassembly of the engine to reach connecting rod fasteners, careful timing alignment, and cautious handling of bearing surfaces. If you are unsure about the process, consult an experienced model engine mechanic.
