While I was picking up the PTO pressure spring at our local Cub Cadet dealer, I learned that many of the kit supplied gauges were wrong. Apparently the owner, a second generation Cub dealer, had a procedure they came up with in the 70’s. for installing the spring effectively. —-He was out today. I’ll find out what their procedure is tomorrow. I’m curious, because when I rebuilt it 4-5 years ago I thought the spring was depressed too much when adjusted with the gauge supplied in the repair kit, and the spring was bent when I removed it this weekend.

You use the double spring with the "6 pin" hub.
I have double spring PTO's on both my 125's |

Springy Springs
Would have to heat treat it I think, then temper it. Hereis a link with details -- https://www.smokstak.com/forum/showthread.php?t=42776 -- first get the part red hot (orange-red, around 850F), re-flatten, and water quench it. That is the hardening part of the heat treatment and will make it brittle, but **Then** you clean off the scale and temper it by heating at around 450 degrees F. at which it will take on a uniform blue color once it hits about that temp - then let it cool to room temp, which wont take all that long 'cause it's small. You might want to practice on some scrap. Parts this small, you are likely using a torch for the heating.
A Google will find you much more detailed information on forming and heat treating spring steel. It will be tricky to figure out how to hold the little bugger so you can get it uniformly hot. Coat-hanger wire loop thru the middle comes to mind. (it will get red and embrittle, too - sacrificial...) |

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.
