Tearing further into the 107 - Page 7

Same thing happened when I opened my K321. The cross shaft and actuator just fell apart in my hands. Engine vibration wore the pop rivet out.

How did you fix yours?

I ran a small bolt and nut through, and then hit the nut with a tiny spot weld. I think anything other than a locking nut will eventually work itself free.

One comment here: I've got an O where the previous owner pulled the threads out of the block when removing that elbow, ruining the engine.

I've got a couple of cubs where I'd like to change the angle of the exhaust, but I've decided "not to fix what ain't broke".

Upside potential: Minimal
Downside potential: Huge

I'm curious, if you take a block to a shop to be bored, would they require that the elbow be removed?
Same question for the dipstick tube?

No, mine don't.

I did essentially the same thing, small nut and bolt. However, I am unable to weld, so I did the best I could giving it a pretty thick layer of JB weld. I know it isn't perfect but once dry its surprisingly strong, for what I use the tractor for (which isn't much) it should be just fine.

And as for the tractor itself, I am happy to say that it (finally) runs! Yesterday morning I took the block over to my neighbor's, and we took the torch to it and applied some heat to the stuck elbow. Came loose no issue actually. Spent the afternoon putting the engine back in the tractor, filled it with oil, and mounted the gas tank. I also set the timing.

Cranked it over for a little while and it fired up. Ran really smooth surprisingly. Amazing how much nicer they run when they don't have a blown head gasket! Still a few things to work out, mainly the throttle cable situation. The tractor has always had a custom thing holding the cable to the engine, but it isn't holding the cable at all, so for now she only runs at idle. Its also running a little rich, but that's an easy fix.

Pictures and possibly videos to come soon, I'm very happy with how this has turned out, even if I had tear apart my replacement engine.

Ok picture time

Well, I realized that I never actually got pictures of the engine itself, which is supposed to be the reason this project thread has dragged on for almost 8 pages. So here we go, all the sheet metal is off the k241 so it's difficult to tell, but if you look closely and spot the oil dipstick on the cam gear cover, as well as the deep sump oil pan, you'll know that it's a k301.

I've made a couple small improvements. Fixed the throttle issue, so now it throttles up and down like it should. Also tuned the carb. However, this project isn't quite done yet. There's at least one more thing I've been meaning to do ever since I started this thread months ago. And that is, adding another flex disc to the driveshaft coupling. I have ran it with only a single flex disc, and that single flex disc takes up a decent space where 2 flex discs would function a lot better. So the plan is to pull the driveshaft and add another. This one's on a time crunch though, since I have the looming deadline of the County Fair to complete this so I can take it there to put on display!

Looking good! Great looking collection

Well, I've been very busy over the past month or so with no time to mention anything I've been doing with/to the 107. Things are finally slowing down so I will update this thread once more.

I mentioned it previously, but the 107 spent a week at the 2021 Wyoming County Fair in Pike, NY, on display with some other functional antique equipment.

It was a tiring but fun week, running hit and miss engines, operating a shingle mill and the sawmill, watching tractor pulls, etc. Even got to do some hauling work with the 107, including 2 loads of firewood for the historical kitchen they use for cooking demonstrations, as well as a load of sawdust from the sawmill used for animal bedding.

I also brought 4 other antique small engines. Other equipment at the show included a custom orchard sprayer rig built from all sorts of old car parts, a "New Way" upright air cooled hit and miss engine mounted on a powder sprayer, dishpan Fairbanks-Morse hit and miss engine, 2 Whitte hit and miss engines, and a couple other hit and miss engines. Also 2 National reel mowers, one of which I actually bought.

Here's the National reel mower I bought, as well as the "New Way".

At the end of a very enjoyable week, it was great to have my 107 on display, but its also nice to have it back at home again. Definitely looking forward to next year.
