All i'm going to say is insurance....take it from there :thumbsup:
I was really hoping for advice for rebuilding this motor.
I have never rebuilt a motor before and have never tore a B&S motor apart before either.
B&S sells .020 under sized rods so I think getting a set of those and having the crank turned down would be the best way.
Does anyone know what seals I should replace? I read that the PTO seal was necessary.
Is there a gasket kit for the motor?
Has anyone here rebuilt one of these motors before?
No one knows the damage till the engine is apart????? You have no idea what you need till you get to that point. Now if it was my problem I would be looking for used parts or if it needed very much like a block or major parts I would look for a used engine. Your neighbor started with used parts so in my opinion why would you need new parts? Also if the seals ain't leaking use them over. Also if the old gaskets still look OK put a little sealant or grease on them and use them over this includes the head gasket. I sure wouldn't spend any more then I would have to if I am doing a free repair job.
No need to replace the Crankshaft, let me know if it has aluminum transfer from the conn. rods and I will tell you a secret to make it good as new; standard size replacement rods will be all you'll need.
What a predicament you have on your hands :frown:
Cool - so you have rebuilt these motors before I am guessing.
Looking at the exploded parts diagram and the Shop manual it does not look too bad.
Do I need to borrow a Torque Wrench for the rod bolts?
And someone told me muratic acid was the trick to get any alum off the crank.
Thinking about it not likely that alum rods could have done much damage to the steel crank.
Thank you for your help very much.
Torque wrench.
You may want to rethink doing this yourself. Just a thought but sounds like its time to bite the bullet. Sorry for misfortune.

The only thing I can add on top of using a the torque wrench is blue thread lock-tight.
it is actually a 14.5 HP motor, is that too small?
I think it is to small. I would ask him what he thinks BEFORE you put it in. Doing things like this is a good way to make bad friends. Even if you have to make a loan do the right thing. When someone borrows my stuff and breaks it I say take it to the shop and have it fixed. You did not even know if you needed a torque wrench Learn on your own stuff. If this sounds harsh sorry Just don't make things worse.

Well thank you Ken but I would rather set it on fire then get a loan to buy a replacement $1,000 engine.
My neighbor has told me that he has never changed the oil in the 6+ years, 400+ hours he has owned the mower.
he was over today to see the old motor and I showed him the 14.5 HP I had and we agreed that we would give it a shot, nothing really to lose at this point.
Does anyone have experience with going down in HP on a yard tractor and what effect it had?
If you can make it fit no one will know the difference in HP. Everything my neighbor does with his 20 HO craftsman my 12 HP wheel horse will do. Back in the 30's a full size tractor only had 10 HP. Back when my father sold garden tractors in the 40's the top HP was 5 HP for the bigger tractors and only 2 or 3 for the smaller ones. Then in the 60's tops was around 8 to 10 HP. Now this day and age we are looking some run up to 30 HP. I don't know how Horse power is rated but for some reason they keep raising it. My thought is you can't really look at horse power. If you say nothing to your neighbor he won't know the difference because he sure won't look at the engine till it blows up next time when he gos another 500 hr on the same oil. Its a good thing you are his good neighbor because I would tell him to shove the mower where the sun shine doesn't shine. You are going away above where most people would go on this.
You could use a 5hp motor it is all in the gearing. Ask a question enough times and you will find someone to answer it the way you want. It doesn't look like your neighbor takes care of his stuff that is for sure. You are doing the right thing talking to him about it. Only a slime ball would try to sneek it in IMHO. You will sleep better when all is said and done. I don't think you are going way above what most people would do you are doing what you know is right. I think that little motor will do just fine after seeing how he took care of the other one. I went a little to far saying to take out a loan but if it were a nice new motor just out of warrenty then I would. I don't put to much stock in people that break other peoples things and tell them to stick it. Would you like that done to you?thank you for your answer.
It was my thought that the big HP mowers are just to help sell them.
Now if this was a commercial mower or saw heavy duty use, that would be different.
He just mows his less than 1 acre lot with it.
I am lucky that the shaft on the 14.5 motor is the same as the one on his mower 1" diameter by 3 3/32" long. Now this motor hasn't been ran in a few years but I am hoping that cleaning out the jets will get it going.
Thank you again for your information

Oh and it really does not matter how good or bad he took care of it it broke while you had it so your doing the right thing by fixing it and talking about it with him
