Removal of front nose spinner .049

Post  WV. FLYGUY on Sun Nov 05, 2017 4:42 pm

Hi forum. I purchased a used Cox .049 Babe Bee today at a local flea market and it has a larger Red plastic spinner on the front. It has the pointy nose with no screw or nut on it to hold it on. I tryed gently to twist it both ways but will not budge. Probably a crazy question but how do I remove it ? Wanting to clean it up completely and put a regular aluminum .049 spinner on it after I complete the cleaning. Appreciate any suggestions. Thanking you all in advance for the help.

Hi Terry,

your spinner is probably the one that pops on and off the prop hub: https://coxengines.ca/cox-.049-plastic-spinner-yellow.html

You will probaly have to force it gently to remove it by pulling it off. Some gummed castor may have "cemented" it to the hub. You may want to blow some hot air by a hairdryer to where the spinner and the hub meet to soften the solidified castor.

Good luck with it, handle it with care..

I believe that it's just a rubber spinner that pops-on over a "spinner-nut". Try pulling on one side of the rear of the spinner using your thumb. It should pop-off. The rubber might be hard and brittle though.. so it could be tough.  

The part on the "right" is likely what's holding that spinner on. It's a 5-40 threaded nut. That's the size of the Cox .049 prop-screw.

Yes I have seen them a lot on my other engines. But this one is hard plastic. I will keep trying. Thanks for the help my friend.

Just wiggle and yank it off. It'll come. Not to be crude compared to any above advice, but there is no need to be gentle, nothing but the spinner could break, and in 50 years I've never seen one break other than in a full speed crash. And they only cost $4.49.

I believe I know which one you have. I had one here and was as hard as you described to get off. I gently pryed it up around the base little by little, and in the end, I still got a tiny crack in it, but used it till it decided to break.....

Here is another style of plastic spinner mount. If you look closely, you can see a sort of a recess in the propeller hub. The spinner has a corresponding shape inside, that "clicks" in the recess. This is the only picture I have on hand and I have no picture of the inside of the spinner, I hope you can figure it out.

(Click the pic and you'll see a larger version)
