It's my understanding that it's not really the balance gear that fails. It's the bearing that fails. Which in turn wreaks havoc on the rest of the engine internals. I throw them in the scrap bin.

dvogtype, thanks for the good news about the crank, didn't expect that. I know you've been around for awhile, so I'm convinced the balance gears got to go. I appreciate the other info as well. Chris

Seems like a lot of guys scrap them.

Because:
1.) They are pullers and running too many RPM's for the balance gears.
2.) They are scared of them.

austin8214 is right, it's the bearings that fail..... so why not just replace the bearings, set them to spec, and keep them in there. You're not building a pulling engine that your only going to get so much life out of..... you're building a worker..... and those gears were in there for a long, LONG time. Seems to me they last! If I was building a pulling engine, different story. No gears then. But for a worker..... why not try and keep it running as smooth as possible. But hey, just my

austin8214, I've heard that.

J-Mech, you do have a good point. I do like smooth and it was running very smooth when I started a refurb ,( going on 1 year now ) . They are still in the engine , so they stay for now.Man do I sound confused. I do understand the pullers shit canning them tho!

J-Mech,

I have a k301 turning 4,000 RPM without any balance gears. It does however have a billet aluminum connecting rod with bearing insert and it runs smoother than any k301 I've seen. It's my opinion that it's best to buy good internal parts and scrap them.

Hey man, I hear you. But you puller guys need to understand that on a regular old rebuilt motor with NO aftermarket parts, running 3600 RPM is not the same animal as your running. I agree, and I'm sure yours is as smooth as you say it is.... but this guy doesn't have custom parts, and isn't running 4000 RPM. That's all I'm sayin. Building a motor to run 300' and shut off, and building a motor to run under load for 4-5 hrs or more straight, and last 25+ years is different. No one is wrong for taking them out. But I don't think you should "just because".

I really don't see any difference in how they run with or without balance gears for mowing. they do smooth it out a little at idle but at 3600 you can't tell. I don't have them in the tractor I use for mowing.

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.
