Replacement upper shell for HPS-CT500

The Futaba 1M11K51803 replacement upper shell fits the Futaba HPS-CT500 servo as a direct swap for a worn or damaged case. It protects internal components and preserves mounting and link interfaces for reliable operation.

To install: remove the servo horn and retaining screws, lift off the original shell, relocate any internal gaskets or fittings if required, then secure the new shell with the original screws. Avoid forcing components and confirm correct gear alignment prior to final tightening.

This upper shell is useful in a workshop or race-day toolkit for fast repairs and to keep servos in service with minimal downtime.

Will fitting a new shell change servo performance?

When fitted correctly and with internal parts transferred properly, the shell itself does not alter servo performance. Performance issues typically stem from gear alignment or damaged internals rather than the housing.

How can I confirm the shell is the correct model?

Verify the part number 1M11K51803 and compare the mounting holes and external dimensions with your HPS-CT500 unit prior to purchase to ensure a correct match.

How often should I inspect the servo shell?

Inspect the shell during routine maintenance or after any impact. Replace the housing if you see cracks, deformation, or if mounting points are compromised to maintain reliable servo mounting and control geometry.
