Kohler rebuild question
Posted November 14, 2011 - 12:07 PM
Chip on the cylinder is not a problem (as long as it didn't deform cyl wall inward around the break). Cylinders usually don't stress crack any more.
The cracks around the pin are a concern, and the broken casting. They can be welded and rebored, but welding on iron is not always a sure thing. May end up cracking again down the line. And is at max rebore, I think you said?
If you are just freshening it up, do the minimum and run the existing block till it dies.
Or if you look at it that this is something you want to last/use a long time, I would go with a new (used) block. If a full rebuild lasts for 10 years, the additional cost amortized over that time is fairly small.
I developed that attitude when rebuilding motors - learned it the hard way a long time ago... A rodded up motor (v8) grennaded because I didn't replace a couple parts that were in "ok" condition, but should have been replaced given the horsepower I wanted. Saving a few bucks cost in the long run...
If you spend money/time to fix it, don't just halfway fix it, or you may be wasting what you spent.
