580 CK What do it do?

[CrazyRay]

I have a 580Ck that I bought all apart and I mean a part. After 6 month I got it a back together running and drivable when I developed(within 5 minutes) the giant leak with transfluid comming out of the starter hole. It leaks about a coffee can in a 3-4 minutes. When running thru the parts book I noticed a large O-ring that goes between the Flywheel and the torque converter that I neglected to put in. Figuring that must be it I split the tractor again. I don"t see any holes in either part that would allow trans fluid to escape. I am now thinking about tearing out the torque converter to look for the problem. However, what does that Large O-ring do? The torque tube was together when I got the tractor and the torque converter was installed.

the starter runs in oil with a torque converter model the starter needs to be the sealed type or the seal is bad in it

Thank you Case Nutty, This machine was in pieces and was missing the starter....The starter I found is from a dry clutch...This explains a lot!

The large Oring on the torque converter serves to keep an oil cushion between the teeth as it retains oil in that area. It will not cause any operational problems but may cause an annoying rattle from clearance between the teeth not being cushioned by the presence of the oil. As CN has stated getting the proper starter will solve the leakage issue as those units have a "wet" bell housing. By gently "massaging" the power steering lines from the pump a Nippondenso gear reduction starter from a C or D hoe will fit right on and you will not believe the difference in starting. If not already use the heaviest cables and the strongest battery you can buy. mEl

Will that starter work on a 480C with the dry clutch? The Delco that is on there leaves something to be desired(new battery, locally rebuilt starter, 4/0 cables).

Thank you for the assistance. I took the starter to a local rebuilder and he instantly said you need a sealed starter...what a way to learn this lesson!

RG, It'll fit right on for bolt pattern and drive, if the cables are made to fit you may have a problem with the Pos cable reaching as the terminal is down and on the side of the starter body. If I were doing the install I would put a Bosch relay in the energizing circuit as the Nippon solenoid takes a bit more current than the neutral start circuit can handle comfortably. I use the update cab relay and harness from the 90 series Ag tractor for this mod. We stock them just for this mod and have a print right in the computer that I made up that we supply with the parts for this setup detailing hookup. mEl

Thanks. Wiring doesn't concern me... I was more concernerd with dropping a bug chunk of change on a started that didn't bolt, or a bendix that didn't catch the ring gear.
