Futaba FUEBS3373 Replacement Servo Case Set for BLS154 BLS174HV BLS174SV  [FUEBS3373]

Replacement servo shell summary

This Futaba FUEBS3373 servo case set provides an RC-scale replacement housing designed to accept the internal components of Futaba BLS154, BLS174HV and BLS174SV servos. The shell retains factory mounting points so the unit installs with minimal modification.

Created as a component-level service part, the case set helps with repair and chassis servicing by allowing you to change a damaged housing or bench-test servo internals without replacing the entire servo. It is intended for model applications only and does not imply any use in real vehicles.

Installation notes: the case set requires careful transfer of the servo’s gear train and electronics into the new shell, checking alignment and engagement before final fastening. Keep original screw positions and verify horn alignment and travel during reassembly to prevent binding or a shifted neutral position.
