my McCoy engines

Nice engines

Phil

Thanks Phil.... Yes... I shot a bunch of photos today... some have the "dryer" backdrop!!!

I'm guessing that the .35 was at least "mounted" in an airplane at one time... I haven't... but a previous owner "skillfully slotted" the frt. mount holes (better seen in the 1st pic) for a model that had once used a diff. engine; I suspect...

Now I'm wondering... if the mount spacing "now matches" that of say; a Fox .35...?

I have 3 McCoy .19 Red-Heads. My dad gave me one a few years ago.. and I got two more last year in a "box of engines" that a fella down the road gave me. The latter two have "lightning-bolt" crankcases.. and were extremely dirty. I gave them a soak in the crock-pot with ethylene-glycol.




The red paint came off from the hot-soaking.. but I knew that might happen. Maybe some VHT engine enamel will take care of that..

Here's a photo showing the difference between the engine my dad gave me.. and the one with the lightning-bolt type-case.




I was able to remove all of the 4-40 head and back-plate screws without incident. I was lucky.. some were in rough shape.

Looking at all three engines from the back-side, I notice that only one of them has the plastic cap on the crankpin..



The two engines "without" the caps, don't really show any wear to the inside of their back-plates. I believe that they "all" should have that cap. I hope I can either "find" some or make them somehow.

I sourced some 4-40 socket-head cap-screws to replace the screws that came out of the engines. I'll need a couple of NVA's too. The NVA's differ between my two engine types.

Some might remember Chellie who checked in here a couple of years back. She makes (or made) overhaul kits for the McCoys and sells them on ebay. They include a replacement mushroom-shaped nylon pin made from a nylon bolt. Early engines actually had a brass pin. Roddie. I'm sure you'll find something to repurpose that will do the job. May be worth looking Chellie up. Her gasket kits were really well made. Her ebay handle is VERYSASSYBLOND. She currently only has one item listed.

Yup, just tell here what size(s) you want or need:

Thanks guys, Yes.. I remember Chellie. I saved a CEF thread of hers to a MS Word doc. on her tips for servicing/repairing McCoy engines.

I also have a wealth of info from Ken Cook that I have saved over the years. (Thanks Ken!)

I suppose I could try to make the nylon button/crank-throw spacer. I have a few diff. size nylon screws around my shop.

As mentioned; I sourced some 4-40 socket-head cap-screws for the engines. The (x4) "short" head-screws and (x4) backplate screws have a 1/4" thread-length. These are a fairly common size at a well-stocked hdwe. dealer. I found them at my local "Ace Hdwe."

The (X2) "long" head-screws however.. have a 13/16" thread-length. The longest common length that I could find in the socket-head configuration was 3/4".. so I went to my local "Fastenal" dealer and bought a box (100) of 1" thread-length black-Oxide socket-heads. I will trim them to the length that I need.. and many of my other engines also use that size.

Thanks for bringing up McCoys roddie, gives me a chance to go over old photos of examples that I bought during my McCoy obsession.  

I remember Chellie too, I think I contributed greatly to her gasket sales.  I remember she was quite generous with the nylon buttons.



I heated most of them in A/F, then disassembled destroying most of the gaskets.  I found it best to heat them half way, then loosen all the machine screws, then finish boiling.



Then I would "sand" blast the case and head and reassemble,  evens the finish out.  Later I learned to work the finish down to a more factory like finish using a light oil and fine steel wool.



The "lightning" bolts had bronze bushings, the others did not.



I ran most of them.





Lot's of variety in these McCoys.



The series 21's are a particular favorite of mine.

Thanks Bob, Some helpful info. there!
