YS Engine YSF9144 Push Rod Cover for 91 and 110 Engines — Service Spare  [YSF9144]

Protective push rod cover for small model engines

This YS Engine YSF9144 push rod cover is supplied as a direct replacement for items identified as 91 and 110 in the product name, intended to protect the push rod area on small model engines and maintain a neater engine bay during maintenance and setup.

Designed as a service part rather than a tuning upgrade, the cover makes inspection, cleaning, and light adjustments around the push rod assembly easier without altering engine settings or operating parameters.

Installation is straightforward for modelers used to basic engine disassembly: remove the original cover, confirm clearances around the push rod, install the replacement and secure the fasteners to the original torque or a similar hand-tight level, then rotate the engine by hand to check for any interference.

Fit this cover as part of scheduled engine upkeep to keep contaminants away from the push rod linkage during pre-run checks and to allow quick swaps while servicing nearby components.
