Stuck glo motors

[swapdaddyxx1]

Realize that this is wrong forum, but maybe some of you old guys can help another old guy.
I have several old glo engines, some 1/2 A,and some larger that were stored in a hot attic over my shop for about 35 yrs. None had ever run much,some brand new never run. Almost all of them stuck.
I don't see any corrision anywhere. some of the half A's have plastic parts such as the TDs.
I have a TD and a fox 35 in PB blaster right now,been there two days with no apparent results. I am wondereing about lacquer thinner, but would be afraid to put any plastic parts in it.
Any of you guys have any magic formulas? All help appreciated. Jerry????

Buy a small container of glow fuel and soak the engines in it over night. This will dissolve the gum that has dried up over the years and it won't hurt the plastic parts. You might try partially disassembling the engines first before soaking them.
After they're all unstuck and turning freely, put them on E-Bay and go out and buy some electric motors. You'll be happy you did. I sold all of my glow engines last year and now I'm entirely electric.
Good luck.

Submerge the engine in clean hot car antifreeze (ethylene glycol) and let stand overnight.:eek:
Wash the engine in hot water to flush off the anti freeze & let dry out, take off the head & back crankcase cover, warm the engine if necessary.
Lube the engine with Marvel Mystery Oil for storage.:tc:

Thanks cb and max, I'll try the anti freeze first, since it is 50 miles to the nearest hobby shop for me. Will the antifreeze harm plastic ? Thanks again to you both. Jerry

Almost all the new cars now have plastic radiators, and all of the older ones have a plastic overflow container. Anti Freeze shouldn't hurt a thing, but don't blame me if it does. ::o

I just ran about 20 glo motors through E-bay that I had inherited, various grades of dirt and burnt on castor, all froze up. Soak in alcohol for a while with the glo plug removed. Put the heat gun to it and easily rotate the prop back and forth.

To clean them I sprayed Dawn Power Disolve dish washing for a few minutes, wash with hot water and a dental brush, it has longer and stiffer bristles.
AIR TOOL oil run through to lube before shipping. That is what I used for afterrun oil, lighter fluid and airtool oil.

This one was the worst. OS 120 four stroke, cake castor.

i have a simple solution.




convert to electric


Electric the new Gas

[swapdaddyxx1]

I have already converted to electric,just want to free those old motors up and run th em on ebay. I have most of them free now, but have another problem. when I took a Fox 35 apart that had never been run, the cylinder sleeve came out also. Now having problems getting it back together. If I put the sleeve in first,I can't get the rod to pivot back enough to get it back on the crank,and can't get everything to line up if I try to install sleeve and piston/rod assembly together. Whats the procedure here? Jerry

[unicorn man]

okay i got you now that makes more sense

[max-nix]

Assemble the crank,rod& piston, then carefully slide the sleeve in the crankcase with the piston at the top of the stroke. carefully twist the sleeve back & forth as you guide the piston into the sleeve.
:)
You can do it!::o

Great advice guys:)
I have also located about a dozen glow engines myself from a few years back. They all need cleaning. Maybe I can sell them or something.

Ive done quite a few of these over the years. recommend you remove the backplate FIRST. disconnect the rod from the crank. turning them over in stuck condition very well can break the rod. most chemicals mentioned here will disolve the castor over time. rubbing alcohol , even naptha works well.be patient.

Hi :ws: denatured alcohol works great for me, just soak them in it for a day or 2, remove as many parts as possible with out putting any stress on the motor, I also like the spray can of brake cleaner with the plastic hose on the end to spray out the carburetor with, i think i spelled that right ????
Take care, Chellie

[Bill G]

Not having any at all works for me.:D
I'm allowed to say that here, right?

[E-Challenged]

If you have a dog, cat or kids, don't leave anti-freeze around where they might driink it, it is a lethal poison and hard to treat. Dogs drink it leaking from cars and die.

[Rodney Ramjet]

If anyone has any rc stuff they would like to get rid of let me know. I will be happy to take it off your hands and you won't have to mess with it.

Just pm me and let me know how much you want for it. I am just starting out so I need everything.

Another solution........
I've done the anti-freeze and it worked well. I thought hummmm, put a prop on tightened it up. Hunted up my propane torch, heated the engine up, with 3-1 oil or a light oil in all the ports (removed plug) gently rocked the prop back and forth using a stolen pot holder on the engine and seemed to work like a charm for me.

I have a small ceramic space heater that I use to heat the engines up and get them free. I put a little Marvel Mystery oil in the exhaust, and the intake, just a few drops, and let the engine get heated up, then I install a prop and gently work it back and forth till it releases, then I generally put some mild solvent in the crankcase, flush it out and re-oil it.
I fly a bit of evrything, glow and electric..still have a rocket boosted Astro Blaster in my inventory too!!(hey..it's ignited elctrically, does that count?:D)...

Everyone who covers airplanes has a heat gun. Thats all the heat you need to loosen castor oil. Alcohol, aceton or MEK soak before using the heat.

Im agree -a torch can apply too much heat too easily. i've only used it when replacing bearings to expand the case.
