Futaba FUEBS3370 upper and bottom servo case set without heatsink  [FUEBS3370]

Upper/Bottom Servo Case Replacement

This is an OEM Futaba replacement housing kit for RC-scale use, supplied as an upper and bottom servo case set matching the BLS152 series naming. The set does not include a heatsink and is intended as a direct replacement body to restore damaged or worn housings while retaining the original internal components.

Use this case when servicing Futaba BLS152 servos: open the original housing, transfer the PCB, gears, bearings, and output gear into the new upper and lower shells, then reassemble and verify gear mesh and endplay. The component is a mechanical enclosure only and does not change servo electronics or thermal management when used without an added heatsink.

Fitment notes: confirm internal component orientation before removal, keep all seals and shims in their original positions, and test travel and centring at low voltage after reassembly. This part supports maintenance, chassis rebuilds, and restorative repairs on compatible BLS152 servos.
