YS Engine YSF9144 Push Rod Cover 91/110 — Replacement Service Part  [YSF9144]

Replacement cover for push rod protection

The YS Engine YSF9144 push rod cover serves as a direct replacement for the parts identified as 91 and 110 in the product title, providing protection for the push rod area on small-scale model engines and helping to maintain a tidy engine bay during servicing.

This component is supplied as a service spare rather than a tuning accessory, easing routine activities such as inspection and cleaning around the push rod assembly while leaving engine operating parameters unaffected.

Fitting requires basic hobby skills: remove the existing cover, inspect push rod clearances, fit the replacement and secure the fasteners to the original torque or a similar hand-tight level, then turn the engine by hand to ensure nothing contacts the push rod during movement.

Use the cover as part of normal engine maintenance to prevent debris from reaching the push rod linkage during pre-run checks and to enable fast replacement when attending other engine tasks.
