Cutless Bearing Replacement Discus and W33

The Discus and W33 Cutless bearing are of the same design and are basically a larger versions of the Centaur arrangement. The procedure for Cutless bearing replacement is as described in Centaur Cutless Bearing Removal and Replacement. More heat may be required to free off the prop. Hot water wouldn't do it for me but a short application of an oxy acetylene torch did the trick instantly. Click here Cutless Bearing Replacement Discus and W33 for more.
