What do you do with a broken lawnmower? Take that sum b*tch apart

!!!error: Indecipherable SUB-paragraph formatting!!!

So as a follow up to my post a few minutes ago. A few people asked for me to post pictures of the carnage back when the original mower died. Here are said pictures.

Ho

Hole in block right behind where the gas tank was

Valve springs

Dunno

All the bolts required to remove the bottom of the engine

Pre bottom removal look at all that oil

Removing the cover too finesse. I named my 3 pound hammer Finesse

Parts everywhere

It all just fell out once I turned it over. All broken

Cam damage

It was bent pretty good

Another angle of the hole

Things that fell out

Part of the cover broken

The other part broken as well

Head removal

There’s your problem

The connecting rod broke in 3 places

Oil covered from me turning the engine all sorts of ways but no gouging or anything else with the bore

You can kind of make out the crack to the right. I’m pretty lucky this happened on the side with the tank. The chunk that broke off was sharp and moving fast.

Now eat it, like a real man.

Nice! I honestly haven’t seen inside a mower before.

I hadn't either.

Hey, a 90000 series briggs. I took apart and built so many of those in college that I’m pretty sure I could do it with my eyes closed. Full rebuild time was about half an hour. The side cover is pretty tough to get off sometimes.

(The SAE Supermileage competition, up until last year, used that series engine)

Finesse definitely helped. I didn't have a wheel puller to get the spinning thing off the top. Wanted that crankshaft

The flywheel sometimes will come off (once you remove the nut, 15/16th deepwell socket) woth a shot hammer tapping around the edge. That said, there’s a good chance yours will be very difficult to remove - the torque from the rod failing may have sheared the key, if so, you’re not getting it off. Happened to us once and we had to make a chain wrench with a sprocket on the output shaft with a 3’ handle. Barely could twist it around enough to get the thing back off.

That’s just extra crank case ventilation man. Good for an extra 5 HP.

I may take a whack at it with Finesse some more but without a work bench or a proper way to hold on to it I feel it'll be pointless

Yup. Vented all the oil out.

Hey a Briggs & Scrap-iron!

With the nut off, you may be able to prop it up so the whole thing is hanging from the flywheel, and use a lead shot hammer (or a block of wood or whatever so you don’t mangle the end of the crank) to pound the crank (and everything else) off the flywheel.
