The pto end cover comes off easily exposing the pressue relief valve,make sure it slides free and the relief port/passage/hole is free of debre,so the excess pressure/flow can escape.
While you have the seal out on the flywheel side, look to see if there is a oil drainback hole and it is not plugged. I can't remember as its been a while but it should be on the bottom. That thing running hot and with no oil while the gear was broken, could cause a lot of problems internally.

Are you getting genuine seals from Cub and are they the right #seal? Are they a tight fit in the Crank case and slip snugly but not overly tight, on the crank? I tore down an engine with two seals installed back to back and they were both wrong! ( of course it leaked) Ha,LOL!

the seals are genuine kohler and yes they are the right ones, they fit snug like they should but not too tight. maybe that is my problem too much oil pressure I should also add that 60lbs was at idle COLD not warmed up but on a dead cold start and close to 75lbs half open I never got to see it wide open or at operating temps cause it would puke out the oil seal before that happened.

well pulled the back plate off and inspected the relief ball/spring the sleeve was a little rusted so i replaced it with one i had laying around that was good and I noticed the spring from another engine had smaller coils(like thinner) on the spring and the spring out of my engine was a little stiffer(thicker coils) so I am taking a gamble and changed it out we will see what happens when i get the new seal I must have nicked the new one when i put it in cause there was a small cut in it and that is were it was leaking so lets see if i can do this again but i am going to run the motor off a belt off my sears and see what the oil pressure is before i put it back in the tractor and start it

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.
