McCoy "Red heads"

Post  rsv1cox on Thu May 14, 2015 8:55 am

A few of you have been having fun restoring and painting the "red" heads of these old McCoys so I thought I would join the fun.

This assortment was on ebay for awhile with no takers. It was offered at only $15 BIN or best offer. I tossed ten bucks at the seller and he took it. I figure the propellers alone were worth that.



Here's the same engine for $59.95 or best offer. I think I will offer $15.... Smile

Lol, admit it you just wanted the Testors engine!

We know the red paint was there to make the engine pretty and to help sell it. Years ago i thought...hmm, let's see: socal company (hotrods) what color would you use? Chevy small block! Wrong, it was a Ford engine color?

Yea, that what i thought? I don't remember Ford engines being red either? But it came from a reliable source and the recommended color is a Ford engine red? Unless its a tractor color?

Maybe, Ford "N" series engines were a pleasent shade of red, later series used blue.  Love the N series, my first tractor ride.

Got the McCoys and props today. Thrilled.....Huh...



The .35 is missing some head screws and looks to be a home made gasket, but otherwise ok. The .049 is a mess, balsa and glue all over but both are complete and the mounting holes are not over drilled. The props are a mixture. I don't know what I would use a 7/3 for.

DO yourself a favor and don't use the nylon props . Their age and composition usually results in a thrown blade. The Top Flite nylon props while they were a good prop when new is always suspect nowadays due to being 30 + years old. Boiling doesn't fix them. Ken

I'm hot to get this engine restored. It's going to need all new machine screws and gaskets which are on the way. But I don't know how to remove the cylinder. Is it screwed on or just held on by the three cylinder head screws? If it's screwed on is a strap wrench the only thing to use to unscrew it?



I want to media blast it (nice thread ian) then reblue the cylinder with gun blue and paint the head with VHT automotive.

The cylinder should just slip straight out, it's probably gum stuck in the case, Take a heat gun to it and get it hot and it take a gloved hand and pull on it while twisting it back and fourth just remember to replace the gasket underneath the cylinder of course you probably know that.

Thanks,  I thought it must be just a straight pull out as any threads would have to be quite shallow, just wanted to be sure before I put it in the toaster oven for a bit.

No problem! Smile
BTW I forgot to mention this and you probably already know when you begin to attempt to remove the cylinder, Make sure the piston is free and at BDC before you start twisting the cylinder, If you twist it and the piston is stuck you could damage or even break the rod! (Bandit)

That's a good looking Dodge pickup too. What year is it? There is one just like it not to far from me. I traded my 2003 GMC Sonoma for a new Honda Pilot and I'm missing my truck.

Bob, it's a '72 model.

Sorry for the thread hijack, I wasn't thinking.

No hijack, my threads are always open to off topic adventures especially when vintage vehicles are involved.  Smile

BTW - That's not me sitting on that Blue tractor. He's probably got hair sitting under that hat. Smile

Progress:











Waiting for new gaskets and machine screws.

Took a hint from a poster here and used ArmorAll to coat the sand (media) blasted pieces. Used gun blue on the cylinder. VHT engine paint on the head.

Hmmm, missed that. I didn't sandblast the crank or piston assembly just took it apart cleaned with 0000 steel wool and oil then put it back together exactly as it came apart. Didn't see a plastic thingy. Is it meant to keep the pin in the piston or prehaps provide a barrier to disassembly,it slid right out.

I think it's there to control crank endplay and to keep the rod from walking back and forth too much on the crank pin. It's a little white nylon plug that fits into the hole on the end of the crank pin. (Bandit)

Some early engines had a brass one. Chellie's gasket sets contain a new plastic one.

This is the only set that I found on ebay for McCoy .35 redheads

http://www.ebay.com/itm/McCoy-35-Cylinder-Head-Gasket-Set-of-2-Upper-and-Lower-NIP-/321370063465?pt=LH_DefaultDomain_0&hash=item4ad3260269

I also bought the crankcase set both from the same vendor larrystoys I believe.  I could not find Chellies sets unless this is one in the same.

There is nothing in the pin, just a hole straight through.



I did find the correct 4/40 head and backplate screws in my Brownells kit., just have to cut the backplate screws to fit.



Still waiting for those kits to arrive. Seller is in Michigan but they are coming from California. Vendor probably.
