FZ110S Crankcase Back Plate - YSF7346A by YS Engine  [YSF7346A]

Crankcase back plate for FZ110S

YS Engine supplies this back plate assembly under the reference YSF7346A for use with the FZ110S engine range. It closes the rear of the engine case and is intended for replacement during overhaul or scheduled service.

The part supports the rear bearing location and sealing faces, helping to retain lubricants and keep debris away from internal components in glow-type RC engines. When installing a new back plate, ensure mating surfaces are straight and free from old sealant or gasket residue to preserve proper sealing.

Fitment note: compatibility is stated for FZ110S series engines. No additional adapter parts are included, so verify the YSF7346A part number against your engine's service list prior to purchase. The spare focuses on maintaining sealing and bearing alignment rather than modifying engine performance.

Order the correct service number for rebuilds to ensure the back plate performs as required.
