    Have any other R66 operators experience a failing or leaking clutch? We have a bad clutch at 267hrs. They offer overhauled exhaged on this part so just have wondered how many have failed.Thanks

    The R66 doesn’t have a clutch.

    Its a sprag clutch inside the freewheeling unit. IPB calls it a clutch. We are changing one tomorrow due to leaking on a low time ship

    Yes The Great wizard at Robinson said they have revised the sprag clutch with better seals and design to R&R. Its still a time consuming job and we all here call BS on the MM and how to R&R it. Let us know how you feel ChoppaDocta once complete.

    Well its easier to just pull the engine than to try to do it with it installed, 2 mechanics 8 hours. We’ve pulled our fair share of R-66 engines for leaking forward seals and engine changes and once you’ve done it a few times its not so bad. It is definitely different than the one we removed.
