Very Helpful Thank the Lord and Your Video !!!...God Bless !!!
Thanks for watching and taking the time to leave a comment. Cheers
Really helpful great video. Watched as was really looking for crankshaft bottom seal replacement as mine leaked very quickly after new, and then bought new mower as did not have time then. Any tricks for fixing/replacing seal or video?
I don't have a video but here's a link to donyboy73. He's got a video over there. Hope this helps. Cheers

@@brantsmallenginerepairs Perfect. Thanks.
I was wondering, for the nut on the crankshaft (flywheel side), is it clockwise or counter-clockwise to loosen? I'm a bit lost on conflicting search results, and without an impact drill heh.
On mowers, it would be counterclockwise to remove. On some 2 strokes, it's the reverse. Hope this helps. Cheers
There is a small, thin washer that came with the small, plastic, black gear that attaches to the crankshaft. In putting things back together and assuming working on this engine upside down as you have it here, would you happen to know if that washer would sit on top of the gear or on the bottom? Thanks!
Bottom of gear. Washer goes on shaft first, then gear. Thanks for watching and taking the time to leave a comment. Cheers
Can you open it up without removing the fly wheel
Is it possible to weld the shaft that the blade bolts to? Sadly i have a spot next to the keyed out area that broke off.
just wasn't sure if the metal is cast or steel.
That's a good question and I'm not exactly sure. It's not something I would try due to liability so it's never crossed my mind. I would say it's cast so not sure how that might work out. Sorry.
@@brantsmallenginerepairs Thank you for the reply and no problem, it looks like cast but wasn’t sure if it was ever done. My worry was if I didn’t get it balanced after welding and cleanup would it have an adverse effect on it.
@@thephreak2151 I think it definitely would but to what extent? It's definitely out of balance right now with a chunk missing so stands to reason if you could weld it, it would be better than it is now.
Where did you source your new crankshaft from ??
It was a used one from one of my other mowers. If you're looking to replace one, try a small engine mechanic in your area or look for a cheap mower in the classifieds that has the same engine. Otherwise, you might want to try an online parts seller like Jack's Small Engines or ProParts Direct. Good luck.
@@brantsmallenginerepairs I am a small engine mechanic but with the pandemic new parts are harder to source 👍
I know what you mean
How you take the pully off the shaft my pully and blade plate are stuck
Thanks for watching. Here is a video on how to remove a stuck blade adapter. Cheers.
