Hirobo HI0304164 One-way Bearing Service Tool for EMBLA EB  [HI0304164]

Service tool notes for EMBLA EB one-way bearings

The Hirobo HI0304164 releaser assists with removing one-way bearings from EMBLA EB helicopter components while minimising impact on adjacent parts. The details are focused on workshop procedure: correct seating of the tool, expected behaviour during extraction, and protection of nearby gears and linkages.

As the title indicates EMBLA EB compatibility, confirm the specific chassis and part codes prior to purchase. The mechanism engages the bearing’s one-way orientation to permit controlled extraction, which reduces the need to pry against gearcases or housings.

Usage tips: match the releaser to the bearing orientation, apply steady axial pressure while supporting surrounding components, and inspect the bearing seat after extraction. This accessory aids routine bearing replacement and inspections that affect rotor and tail drivetrain settings but is not a substitute for a bearing press or full diagnostic checks.
