56SR Regulator Body B Replacement - YS Engine YSS2037  [YSS2037]

56SR Regulator Housing B Overview

This regulator body B serves as a spare housing compatible with the YS Engine YSS2037 range and is intended for use on 56SR regulator assemblies.

Replace damaged housings to restore correct mounting geometry and sealing. Inspect the original gasket and linkage positions, align the housing carefully, and fasten in stages following the maker's guidance to maintain internal component alignment.

For regular maintenance the body provides the structural support for regulator components; a fresh housing can prevent leaks and help keep steady control response in RC engines. Always verify fit on your specific 56SR regulator before final installation.
