New year, new engine
Rebuilding a 48 engine. Getting it bored .020. so new pistons and rings are obvious. Changing the crank, and new bearings are obvious as well. Should I go with new rods while I'm at it?

Re: New year, new engine
If the Rods are not damaged they don't need to be replaced, just the bearings. New pins and bushings may be needed. Install the rods in the same piston and pay attention to the numbers on the bearing caps. The Blue Ribbon Service manual has all the details described. Available from links on this site.

Re: New year, new engine
I was just wondering cause before I bought the tractor the #1 rod broke. They replaced the rod but never fired the engine. Turned out the crank was bent then one thing and another which leads me to total rebuild. So just wasn't sure if it would be safe to get new rods or just not worth it. I can't find any where with new rods, only salvaged.

Re: New year, new engine
If you are going for a professional rebuild I would let them inspect and purchase needed parts. If the crank is bent there could be other damage that only a engine builder would find.
When you only have 9 horsepower you need to know the names of all of the ponies!

That is also where I have found I get the best price on parts. I also let them reassemble mine, they have much more experience than I have.inairam wrote:If you are going for a professional rebuild I would let them inspect and purchase needed parts.

you are part of the problem!!!

Re: New year, new engine
the number one question is why did #1 rod break in the first place, was it a crack from years of use, did they over speed the engine, or did it loose oil pressure and spun the #1 rod bearing. its a hard call, personally i would have a machine shop inspect the rods, line bore the main bearings, and check the block for cracks

That also helps if something isn’t right, they have to eat that replacement cost, not you. Nothing worse than having to go back in when you think something is right.

Re: New year, new engine
Nowhere around here will put an engine together with machine work for 1k or more. As far as the rod breaking I don't know why it broke other than a guess that the bearing failed of some sort cause the way the journal looked. If I would have been told why I wouldn't believe it anyway after what I have seen with this engine. I also cant find new rods anywhere. So I'll just have mine checked and new bushings put in. Piston kit I'm gonna buy comes with new pins
