Well the wooden dowel worked surprisingly well!! The piston came right out and there was more oil in there than I would have thought. A quick feel of the cylinder and it seemed fine. Piston is clearly toast. Edit: It occurs to me the piston did not seize up. Based on how easy the piston...

Could I stick a screwdriver down the spark plug hole and try to hammer it loose?

Yes, not much use in cleaning the crank if the cylinder is not good. I removed the crank to get a better look and the piston is near the top of it's compression, exposing much of the cylinder walls. It actually looks very good. I have not removed the valves yet. What is the best way to free...

The gouge in the crankshaft is raised above the surface kind of like a crater. I assume the piston is stuck, which is what caused the problem. Question is whether this is salvageable or if I should be looking for a new engine.

OK finally got the engine apart and it looks like the connecting rod snapped. What do you guys think?

Hope I get that lucky! Either way I have to take it off the mower deck so I might as well pull it apart and see what happened.

I know it was a bonehead oversight. I think checking the oil every time I mow the lawn is a bit much, though. Sometimes you have to learn by making a mistake. My only defense is that 2021 has been a very challenging year for me and checking my lawn mower's oil wasn't on my radar. It will be...

Well the flywheel came off. It just needed a longer cheater bar. I am trying to remove only what is necessary to figure out if the engine is recoverable. I haven't done this before so I will have some stupid questions if some of you will help me out. For instance do these plastic restraints...

Well I'm still trying to get the dang flywheel off. I have some time today so I got a bigger wrench and a better cheater bar. I'm using a 3 prong puller and I feel like I'm going to break something. I have the nut removed - not sure what else could be wrong. Why are these flywheels bonded so...

Thanks for all the great suggestions. I picked up a half inch socket wrench (beefier that what I had) and found a 6' pvc pipe for a cheater bar... yes I said pvc. It actually worked! I didn't try to block the blades because this mower has a blade clutch and I didn't want to mess with that...

OK so I'm trying to take this lawn mower apart and after 2 bloody fingers and a strained wrist I am learning that there are some specific tools required for engine work lol. I tried removing the crank shaft nut with my impact drill but no go. I am trying to avoid buying an impact driver but...

Thanks! We were both posting at the same time so this helps answer my last question.

Thanks for the suggestions. While I'm capable of DIY projects I've never disassembled a mower like this before. Are there any good references/step by step type info available to help things go more smoothly? Or, do I just start taking everything apart until the motor comes out? lol

Unfortunately, I guess that's what happened. The shaft was frozen solid until I got it freed up with the socket wrench. Maybe the broken part was keeping the shaft in place until I moved it. How difficult is it to replace a motor? These mowers aren't cheap and if I can find a replacement...

When I turn the blades the nut in the middle also turns. Originally originally nothing would turn so I so I put a socket on the nut and made it turn which was not too difficult to do. I'm not sure if that addresses what you were saying.

Yeah I put a screwdriver in there and nothing happened.

Hi. My first post in this forum! I ran my Honda HRX217HZA with the GC190 engine dry of oil stupidly about a month ago. It seized up and I thought I was done until I started googling it. Apparently a lot of times the piston can be freed with some penetrating oil and a wrench. I removed the...
