hmmm...wonder what's hiding behind that starter:



^ definitely a broken connecting rod...but the block is definitely salvageable.

oil level wasn't too low...it does have the consistency of 30w though.


I guess it's also possible that the linkage was binding-up.

dismantling the engine

Pre-safety module era:






something not quite right with this scraper bar...I could be wrong but I believe it's installed incorrectly (hence the excessively tall skid setting)


Yay! Wheels aren't frozen to the axles!

and there's your broken connecting rod.




...and a sheared flywheel key:


The crankshaft, piston & cylinder are in great shape!

shortlist of things to do:
  • measure ring-gap & bore
  • clean-up the crank with some emery cloth
  • install new oil seals
  • rebuild the carb
  • valve job
  • new head gasket
  • new fuel line
Everything on this machine is original...I'd like to keep it that way! :cool:

I think I'll try and save this one Gusto. It's old but I don't think there are a ton of hours on it.
It's worth a try to see if it can be repaired. Clean up the crank and get a new connectiong rod and braze the crankcase shut and if it is still a total loss then you can always repower it.

pretty good shape for a 1981, even the paint looks good, maybe wasn't ever in salt, definite candidate for unrestored original condition equipment honors.

No doubt!


My understanding is that she spent her entire 37 years on 1 property.

Regarding the cutter bar; I think that's one of the pivoting Toro special features. Hard to tell from the pics though. Yours might be binding.

i have two more buckets and a tractor for a 524 i can give you if you want more parts
Thanks Man! Everything on the tractor is in really good shape. I'll treat the rust on the handlebars & spot-treat the surface body rust.

It actually pivots properly... the bucket needs to sit higher than my Toro 824 to provide clearance. It might be missing the spacer that pulls-up the scraper up a bit. We'll see; I'm focused on the engine at the moment.

ClassicCat..I just repaired an 8 hp Tecumseh with JB Weld that was a little worse than yours....three light coats.
Thanks cranman!

I was thinking of using JBWELD from the beginning...then Gusto mentioned the brazing rods so I'm looking into that as well.

I use JB for filling top-side holes on aluminum boats...and it sticks to Al surprisingly well if you prep it right.

when she pulled-in, she thought that I was summer-izing one of my blowers... unfortunately she tells me this AFTER I've already fallen on the sword! :smiley-confused009:

I picked-up some JB-Weld High-heat in a stick form.

I didn't want to play chicken with the working time...so no step-by-step photos of it being worked :cool:

Embedded the patch in some JB High-heat & bucked a pair of 3/16" solid rivets:




^^ I'll fill that outside crack later.

I used the pieces of the connecting rod & crank to verify the fit:
