FS-40S Pushrod Replacement OS45266010 for O.S. Engine  [OS45266010]

Pushrod for FS-40S and FS Engines

An RC-scale replacement crafted for O.S. FS-series engines, this pushrod links the rocker assembly to the valve mechanism in nitro model powerplants.

Hobbyists and tuners can use it during maintenance to adjust valve lash and idle settings without removing or modifying core engine parts.

Installation notes: install on a cold engine, orient correctly, secure clevis or retainer at both ends, inspect associated bearings and linkage pins, and carry out a low-throttle verification run before full operation.

Maintenance tips: clean the linkage regularly, check for bends or looseness after impacts, and replace the pushrod if any deformation or excessive wear is detected to keep valve timing predictable.
