It sounds like a bad rod but maybe not. First, download the Kohler Manual from our Manuals Section. Clean everything about the exterior of the engine. Follow the manual to disassemble. Have labeled containers to identify parts as you take it apart. Inspect as you go. When you have found the problem you can repair just it if the rest looks good or rebuild the engine. Complete kits are going to run you close to $100 to $200 for aftermarket. Watch them, most of the kits do not include the bearings. The manual is excellent. A properly rebuilt Kohler is beautiful. Good Luck, Rick
PS. One common problem is improperly torqued connecting rod bolts. They require a special technique as described in the manual.

By bearings, he means the roller or ball bearings that support the PTO end of the crank shaft, and sometimes the flywheel side depending on the build specs for that motor. The rod journal doesnt have replaceable bearings, just alum rod on metal crank. It might have loose rod bolts, I have seen that before in a K171 Kohler, or a worn wrist pin ect. Also pay attention to the cam shaft end play. I have seen fully rebuilt Kohlers sound like they have one heck of a knock at higher RPM's due to the cam slapping back and fourth. There is a book speck for it. Any time spent on doing it right while its appart, is time well spent. Mike
