Back Plate for FZ110S Engines - YSF7346A by YS Engine  [YSF7346A]

FZ110S engine rear closure component

The YS Engine back plate identified by model YSF7346A is a replacement part made to fit the FZ110S engine family. It functions as the rear closure for the crankcase and is intended for use during normal servicing and rebuilds.

This assembly houses the rear bearing interface and sealing surfaces, helping to keep lubricants inside and contaminants out of the combustion chamber area on glow engines. Before refitting a replacement back plate, inspect bearing bores and clean seal faces to preserve the engine's sealing integrity.

Fitment advice: the product title indicates compatibility with FZ110S series engines. No fitting adapters are supplied, so check the YSF7346A against your engine's service parts list before purchase. The spare preserves sealing and alignment rather than tuning engine output.

Confirm the exact service part number during maintenance planning to ensure proper fit and long-term reliability.
