YS Engine YSF1826 Back Plate FZ120 replacement part  [YSF1826]

Back plate for FZ120 engines

This YS Engine back plate is presented as a direct spare for the FZ120 line, identified by model YSF1826. The copy focuses on use as an RC-scale engine back plate, clarifying its role in engine rebuilds and routine maintenance without claiming additional features.

Fit and role: the back plate secures internals at the rear of the engine assembly and serves as a mounting reference during disassembly and reassembly. Expect it to be used when rebuilding the FZ120 engine series or replacing a worn or damaged rear housing component.

Installation notes: check for correct alignment of mounting holes and mating surfaces before tightening fasteners, use appropriate thread-locking practices for metal-to-metal screws if the engine manual specifies them, and verify crankshaft endplay after reassembly. This text avoids specific torque values or tools to prevent inferred instructions beyond the part description.

This spare back plate is intended as a straightforward replacement part for FZ120-class RC engines, useful during engine rebuilds or when replacing a damaged rear plate; confirm fit before permanent installation.
