S76 Tail-rotor Pitch Change Bearing R&R Work Aid
Saves time and slowly presses the bearing in or out.
You don't need a hydraulic or arbor press. You don't beat it in/out with a hammer.
The risk of damaging a part when using a hammer is so great it's a no-brainer.
The cost of one damaged T/R link, M/R link or damper is many times more expensive than a complete set of the work aids found on this page.
