    Default Spinner bracket?

    Hi,
    My spinner has this attachment behind the spinner, looks like a home made thing. Is this original and should we replace it or simply remove the thing? It is a metal Sensenich prop on a 235. The spinner backplate is fine.

    Never seen that before. Should be a forward bulkhead on all that I have seen.

    So do you think it’s not the correct spinner?

    Looks like the correct spinner but never seen one without the front bulkhead and not with the bracket shown in your second picture.

    Normally the "strap" was used on wood props due the thickness of the hub and shank. Also wood props need a crush plate which makes fitting a bulkhead difficult.

    From the pictures it looks like a spinner used on the Sensenich metal AM series prop. The Sensenich AM76-2 used on the Lycoming O-235 did not use a bulkhead assy. on early acft serial numbers. It used strap U12330-04. https://www.univair.com/piper/parts/...spinner-strap/

    From the riveted patch repairs on the spinner it looks like someone patched the holes for the original strap attach and then fabricated a new strap and created new mounting holes for the fabricated strap.

    Good to know. Both my Clippers and all the ones I have been around with the 235 had the two bulkhead spinners. Have not seen one with the wood prop and that spinner arrangement.
