So I have this tiller, which was a real troublesome engine to start. I assumed it had a sheared, or partially sheared key.
THAT turned out to not be the case. I believe it, after a suggestion by a viewer, has the wrong flywheel, as it's likely a lightweight flywheel, meant for a lawnmower, which uses the blade as the flywheel momentum to keep the engine spinning, to make starting easier, and maintain rotational energy between power strokes.
I looked online looking for a broken lawnmower that I can salvage the engine on, with either a Tecumseh engine, or one I can replace the Tecumseh engine on, with a different one that is more reliable, like a Honda, or a Briggs.
I came across a Lawnmower mower, with an engine with a hole in it. I thought, hrmm, this might make a good video. It turned out to be a good idea overall, as I got a better idea on how to take these silly things apart, as I have a couple that I need to take apart.
Including a Craftsman with a piston with many holes in it. Kinda needs to be fixed.
I have an upcoming video on that, as well as a blog post, so stay tuned.
Well, getting into the tear down...
It started out pretty simple. The bolts weren't too tight at all, but using the impact driver, it made it pretty simple, and quick.
After getting the engine shroud off, I had an idea about recovering the flywheel key, as well as the flywheel. I wanted the Key for that Tiller, and needed the flywheel for a lawnmower I split the flywheel on. Oops!
The flywheel key, however, was toast. It clearly sheared when the engine blew itself apart. Well, that was tragic!
After the flywheel was pulled, off came the carburetor, and air filter box.
As soon as that intake came off, tho, a whole bunch of oil came pouring out of the intake. Oil should not be coming out of the intake!
After that, it was time to open the head and see the shape of the valves and piston. So, 1/2" inch socket, impact driver, and I ripped them off pretty quick.
Head came off pretty easy, but I must say, the resemblance to "Truck Nuts" is rather uncanny...
What a disaster!
Spinning the Governor |
Like I was mentioning about the crankshaft. It was still in great condition, other than the fact that I buggered the threads.
The Engine Block was in really good shape, especially the bore. But with that gaping hole in the side of the block, it was destined to be scrapped, and that's exactly what happened to it.
I learned a lot with this teardown. I definitely learned a lot. The biggest thing I learned about it was making sure to prepare the crankshaft so that I can remove the sump easier, which is something I'll be doing on the next teardown! I don't want to have a repeat where I was smashing the heck out of the crankshaft, and sump, for 30 minutes straight because it just wouldn't come off...
Anyway guys,
Chat soon!
