  • Tapered shaft, prop hub questions

    Why the tapered shaft? Was the flanged crank inadequate?

    An earlier thread discusses installing a wooden prop on a tapered shaft. I understand it's a two step process: a) install the adapter on the prop, then b) install the adapter to the crank. Correct? If so where can I find the torque values for operations a & b?

    Do you ever run into any problems removing/installing the adapter to the crank?

    Second, the engine stands I've seen for the A-65 bolt directly to the flanged crank. With a tapered shaft do you install the adapter and continue as if you had a flanged shaft?

    Sorry, never been exposed to this configuration - Mike

    tapered came first.... one way is to install the tapered flange then bolt to the stand. OR we had a hard wood engine stand post that had a tapered hole that the tapered shaft fit into very nicely.

        Ah Mike you are a treasure The neat part about the tapered shaft is the ease to remove the nose cowl with all the other cowl to work on the engine. Mooney has a flat rate of about 1 1/2 hours for cowl off and on .... WE have about 20 mins with the tapered shaft. I still have a slightly tapered bar about five ft. long for the remove and install. Sometime I will show you the torque method for a 92" Curtis Reed prop on a large radial. Four to six foot bar and 180 lb person and a large hammer.

          I could remove the nose cowl and all the other cowl at the same time with my flanged crank, but can't with the hub. The hub extends just a little farther out and it get's hung up on the exhaust pipe. Maybe I can make the exhaust pipe hole a little bigger. It's an owner manufactured cowl.

            You lost me on that one.... The nose cowl will not go over the flange. I remove the tapered hub WITH the prop attached in about 2 mins..... Yours must not be a Taylorcraft cowl....
