I recently came upon this on another forum. Someones idea of an engine stand.

I would really like some comments.

Rob,
What do you think?

    What does the FACTORY think?

    I think it is a throw-back to someone's conti and lyc days. Not ideal for working on the gearbox!

    My thoughts were it may tweak the prop flange because the engine has enough mass if pushed over a tad, possibly damage the oil seal and or bearing leaning to much one way and maybe putting some of the factory residual oil where you may not want it. The last one may be a stretch, I just don't know.
    I have never seen anyone do this to a Rotax or even heard of such a thing.


    Other comments or ideas?

    The ones done in A&P school or other places were most likely direct drive engines like Cont. & Lycoming and they didn't have a gearbox.

    The gearbox is a major game changer.

    Here is the comment from high up in the Rotax chain.

    "Both are bad news for the engine. Let is remember that this is not a
    direct drive, the weight and all the forces are not in direct line with
    the crankshaft, it is offset to because of the gearbox.

    This type of mounting is common on direct drive engines and should be
    avoided on geared engines for this reason. The worst is the one were the
    engine is flat and all the mechanical leverage on the prop flange could
    perhaps cause a real problem with the bending or fractures of the inner
    bearing retaining bolts."


    Bottom line don't do it and don't treat a Rotax like a Cont. or Lycoming. Number one mistake by A&P's working on a Rotax. Fixing A&P work on a Rotax is approximately 30% of my business because they either treat them like a Cont. or Lycoming or have no idea about LSA regs.
