YS Engine YSS1016 Back Plate for 50ST Engine Replacement  [YSS1016]

Rear housing purpose and compatibility

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 acts as the engine rear housing that locates mounting points, retains internal assemblies, and provides a service access surface when the engine is stripped for maintenance.

Focus here is on fit and workshop handling rather than material claims. Use this plate as a like-for-like replacement when removing the engine rear cover for routine service, inspection, or to swap worn components. Confirm the part marking matches YSS1016 before you proceed with installation.

Installation notes: where practical remove the engine from its mount, follow the original fastener pattern, and keep any gaskets or seals together with the back plate. Start fasteners by hand to check alignment before final torque, and inspect mating faces for burrs or debris to ensure an even seal. Replace seals if they are present during reassembly to maintain reliable operation.

Tuning and workshop role: the back plate gives access for internal inspection or adjustment without directly changing tuning settings, but clean mating faces and correct assembly will help preserve baseline performance. Keep a spare YSS1016 in your spares kit for quick turnarounds at the field or during event checks.
