Colt Case Ingersoll Garden Tractors

Guys, I found an old CCK looking engine that used to be on a welder. It was on a Lincoln welder by the red paint, but the armature of the welder went bad. Would this be a suitable engine to swap into my 646? It has no starter, as the welder started it. It also has an interesting ignition on it that appears to be a magneto instead of a coil. Also, it doesn't have an oil filter, very odd. Let me know what you think!------Metalguy

Metalguy, that is similar to the one I have. do know the governor balls would have to be changed to get the 3600 rpm from the engine that you would want for a GT. Harry

@metalguy . That is the same engine that is in Frankie . 446 Snow Blower tractor has a Emeral 4000 genny engine . That being said . What you have is a short block with a tappered shaft . You will need to do what I did to the genny engine . Read this . viewtopic.php?f=6&t=539&hilit=genny+engine&start=10

I also converted a lincon welder short block to use in a 448. I turned a tapered shaft down to 1", changed the governor balls, and used a Case pan. Case uses a deeper pan and tins than welders and generators. Also dipstick is in a different location.

What is really odd about this one is that it has a straight, large shaft. I'll try to get pics today if possible. I have one with a tapered shaft that I got as a shortblock (reman) in my other 646. What I did with that one is I bored a taper to match in the lovejoy connector. Works great, and easier (to me) than removing the crank, and machining it straight. Those of you that have used an engine like this, did you keep the magneto set-up, or just convert it to coil?

The P220 is tapered lovejoy to match crank and the RV genny engine is remachined . Both do work if done properly .
the P220 welder engine has electronic ignition (factory onan ) , the RV genny engine is points . I have never seen an onan with magn ignition . A large straght shaft ? Wounder if it is a big block 60 cid (1000 cc ) . Do you have a 16/18 hp onan head gasket that you can see if matches the bolt patter on the head ?
Can you show a picture of this magneto set up .

I'll go out and take some pics today, and post them here. I have never seen this set up, and it appears to be very old. It has points, in a raised box, but no coil, and the plug wires go insisde the tins towards the front fan area. Very strange. ------Metalguy

For some reason I can not open the image . Anyone else ?

Sorry if the first attempt didn’t work. Hoping these pics will show ——-Metalguy

As you can see, it also has a mechanical fuel pump on top by the carb. I’m guessing it is to prime for starting, as it has a knob to run it. Everything about this thing says old to me.——Metalguy

That looks like an old CCKA or B . I am no expert , Boomer is . But look at this . The heads are consistent with the CCK /A, B . http://enginemastersinc.com/onanrebuild ... mation.htm
The RV genny engine I have is a BG with B43M heads, intakes, ignition ect. upped to 3600 rpm . Makes great power . The CCK... are the same bore and stroke as the BG .
If the engine inside is in good shape , it will make a great short block .

Does anyone have a good source for a CCKA engine gasket set?

Great let us know how you make out .

This one has no provisions for an oil filter. On that side of the block it only has an allen screw in one hole, nothing else. I'm guessing that hole would be for an oil sender unit? I removed tghe oil filter housing from the side of the bad engine, and the block has channels machined for the filter, and the housing itself has the sender unit in it. I assume it could be machined for the filter housing, but that means a complete teardown to clean out any chips, and I don't want to do that, so I'll probably just live without a filter, and do oil changes more often. -------Metalguy

I have made some progress… I made a block off plate because of the lack of oil filter, and made a muffler as the original one was…rusty and modded. ——Metalguy

Well done sir @metalguy . The tin man would be proud of that . What grade of stainless you using ?

Great workmanship! Are the muffler parts laser cut from stainless?

Muffler is made from .050" 1/4 hard 347 stainless. Cut with waterjet. Should outlast the tractor, but with Case, who knows? I made it in a hurry, and could have done better, but I am about ready to start this thing before install, and that old muffler was probably going to just spew rust and squirrel bits everywhere if I put it on there. So hopefully I'll get it running this weekend, then start the install if all goes well. I have the points adjusted, valves too, just a few small things, and put the oil in, fuel line on, and let her rip! -----Metalguy

@metalguy it looks great! You said you could have done better if you weren’t in a hurry. If I tried to make a muffler and taken my time it would end up looking like your old one!

Very nicely done!

Great fabrication Metalguy. I’m not familiar with 347 SS, but figured it can be hardened. Is it magnetic? If so it has some iron in it. I’m curious what colors it changes to when it gets hot. Harry
