Default Question on undersized rods

Took. My engine to the machine shop after work told what I wanted done and will have to wait a week till the get back to me with measurements , anyways I was told if it needed a .20 under rod it would need a bearing installed. I thought a .20 under rod didn't have bearing?

You can get a .020 under rod through Kustom Lawn and Garden. BTDT Extremely fast shipping. Ordered one day received rod 2 days later.

I'm going to start doing bearing inserts on all my rods. That way, they are re-usable. You can go with a .020" under if you want. My machine shop will machine the rod and install the bearing for the same price or just a little less, than a new rod. Your choice.

I don't know what size I need as of yet. I just thought a .20 under rod was made like a standard size just larger to accommodate the turning of the crank from machining . From way it looked could be within spec, both rod and crank look fine. Oh he also advised against reusing the old rod even if good on specs . He sad he would worry about fatigue of the rod.

That is correct.

I've not seen very many cranks that were "withing spec" enough that they didn't need turned. Expect at least a .010" under.

Please excuse the machinist ( ) as he nitpicks your post.

When the crankshaft rod journal is turned .020 undersized, it will require a connecting rod with a smaller hole size to have the correct clearance.

He is correct on the rod, aluminum fatigues with use and it will fail at some point.

That's what I was thinking too .10" under. The place was busy several 6 cylinder blocks a 3 cylinder jd block , quite a few diesel heads. It is a new building, their old one burned last fall they lost all their machines several engines. Thanks Jonathan for confirming what I thought about the rod . That's ok Jeff no problem with nit pickin !

I thought of doing that at one time but I came to the conclusion that just using a new rod was better. I really don't trust boring a used rods unless it the K361 rod

Afraid of rod fatigue? Dean (my machinist) and I discussed rod fatigue. We didn't think it would be an issue, but weren't sure.

Do you run any of your motors with bearing inserts? What about boring a new rod?

I may still try it on some of my own (just because). I've got a few good looking Kohler rods that I wouldn't re-install just because they are used, but they aren't "spun".

yep, its a bad rod to start with. I wouldn't be afraid to insert a new one. I stopped doing inserts when I could no longer get or find the K361 rod. the last few stocker pullers I did ,I put a stock length aftermarket rod in. you do need to rebalance the rotating assembly

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.
