YS Engine YSF1826 Back Plate Replacement for FZ120 Engines  [YSF1826]

FZ120 rear plate details

The YS Engine YSF1826 back plate is described as a straightforward spare for the FZ120 series, aimed at maintenance and rebuild scenarios rather than upgrade claims.

Purpose and fit: the rear plate secures internal parts at the engine rear and provides a consistent mounting surface during disassembly and reassembly. It is suitable for replacing a damaged rear housing on FZ120 engines when compatible.

Practical fitting notes: check for correct alignment of mounting holes and mating faces before final torqueing, follow any thread-lock guidance shown in the engine manual for metal fasteners, and confirm crankshaft endplay after reassembly. The description deliberately excludes precise torque figures and specialised tooling instructions.

This back plate is intended as a direct replacement for FZ120-class RC engines during rebuilds or when replacing a damaged rear plate; always confirm fitment with your engine parts list before installing permanently.
