YS Engine YSS1016 back plate 50ST, engine back plate spare part for RC models  [YSS1016]

Back plate role and fitment

This YS Engine back plate is a direct spare part reference YSS1016 intended as an RC-scale replacement for the 50ST family indicated by the model name. It serves as the engine rear housing component that locates mounting points, helps retain internal assemblies, and provides a service access surface when the engine is disassembled for maintenance.

The text focuses on functional fitment and workshop handling rather than material claims. Use this plate as a like-for-like replacement when removing the engine's rear cover during routine service, inspection, or when swapping worn components. Confirm the part marking matches YSS1016 before installation.

Installation notes: remove the engine from its mount when feasible, follow the original fastener pattern, and keep track of any gaskets or seals removed with the back plate. Hand-tighten fasteners first to verify alignment before final torque, and inspect mating faces for burrs or debris to ensure an even seal. If seals are present, replace them as part of reassembly to maintain reliable operation.

Tuning and workshop role: the back plate provides access for internal adjustments or inspections without changing tuning parameters directly, but clean, square mating surfaces and correct assembly help preserve the engine's baseline performance. Keep the part in your spare-parts kit for quick turnaround during field maintenance or pre-event checks.
