Well there is another way. In kohler manuals it says if it's really bad you can weld a lot on the journal and then grind it until it's back to the factory dimensions. Be hard but I don't see why a profesional welding shop couldn't do it. Just a thought......

I would find another crank before I would weld that journal. Chances of warping the crank shaft would be my biggest concern and even if it didn't warp the machine shop cost to turn it back would be astronomical. It would be cheaper to find a good used crankshaft. Like I said in a previous post you can buy .020 under rods and be done with it.

Only thing bad with 20 under is once it's bad it's bad. You can't grind in down anymore. Or at least you shouldn't. While my method will make the crank last a lifetime of cared for.

When you weld a crank, the welding shop doesn't do it. You take it to a crank shop and they have a submerged arc welder that they use. OR... a welder than I can't remember the name of right now... but it basically "blows" hot metal onto the journal. It sounds odd, but it is a method of welding that is less evasive with less heat and warp-age. But Kelly is correct.... even my crank shop won't weld up the Kohler cranks. The hollow journal makes it prone to cracking.... ok... it WILL break. Now that shop only has a submerged arc welder, not the other machine. I asked him once if he would do it with the other style... he still said no. This is the same shop that works with Vogel MFG, so..... he know's what he's doing.

I will politely disagree with you on that statement. I have had a crank ground farther down than .020 and had the rod machined for an insert. That engine has 10 yrs on it now and still going strong.

Guys

I went back into this thread at the request of the OP and deleted the argumentative comments. So if any of you wonder who it was that deleted your posts it was me. If you wish to discuss the issue feel free to PM me.
This thread is now closed again.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
