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

The YS Engine YSS2011 crankshaft is an OEM-style replacement intended for the 56SR range of model engines. It functions as the rotating assembly center and is supplied as a single spare for maintenance and tuning operations on hobby RC engines.

Service guidance: confirm your engine is stamped 56SR prior to ordering, inspect bearings and seals during removal of the old crank, and maintain cleanliness while reassembling to avoid contamination. This item is exclusively for model engine applications.

Replacement generally requires disassembly to access the connecting rod and timing components; handle bearing surfaces with care and ensure correct timing alignment. If you have limited experience with engine teardown, engage a technician familiar with glow or model engines.
