Re: Propeller Removal Preparation

I'd try this for restricted access
13 pc Harmonic Balancer Puller Tool Set Damper Removal Installer Kit | eBay

Prefer standard 3-jaw when room allows, sized to clear hub.

plus this
BEARING SEPARATOR 1502 | eBay
Different sizes are available. Choose one big enough for your hub, grind out centre to fit your shaft if necessary.

In your case you might need to shorten the centre screw on the puller.
Ought to be usable with 2, 3 & 4 blade props.

Hope it might help someone.

This proved to be a mistake! I guess it's never wise to expect that you have received the exact product that was ordered! I was called by the manager of the propeller machine shop where I sent my prop and found that the bore was cut for a 1 1/8" shaft and not a 1 1/4" inch shaft. I've looked at the data sheet ordering form and noticed that the error was probably substituting 1.125 for 1.25 at some point. I'm not going to be able to trace the source of the error or be concerned with fault.

Maybe, ....or maybe not. This causes me to consider another question. I seem to remember hearing of some props put on shafts with sleeves that isolate them from the direct metal contact with the shaft and reduce the potential destruction by electrolysis by this barrier.

This is just some faint memory of hearing of such a technique. Does anyone have an answer for this? Have props been installed with a larger bore and a non-conductive sleeve? What,- a ceramic key?

I'm not in pursuit of this, but it interest me.

Re: Propeller Removal Preparation

Yes, nylon shims are available to make a larger bore prop work on a smaller diameter shaft. And while metal-to metal contact is reduced, it is not eliminated, as the key and the nut will still be in contact with both the shaft and the prop

Re: Propeller Removal Preparation

The Prop Shop - Anchor Bushing - The Prop Shop

Was thinking about adapters a while back and these people seemed to have most imperial and metric sizes.

Nylon is about a third the price of bronze - can't see an advantage myself, think I'd go for the bronze.
