Im finally getting time to start working on the Cat Ten. I want to replace the head studs before installing the head.Are they still availble from Cat?.If so I would appeciate the part number,I dont have a parts book yet.I tried one local supplier and the studs were to short .Thanks John.

The studs are still available but cost around $10 a piece. I had to remove some fine thread studs a couple of days ago and when I double nutted them to try and get them out they would just slip on the fine threads. I have a buddy at work that has a stud remover kit that is design for each specific thread, they work just like two nuts but they are bigger and the one piece has a o-ring on it. They worked really well I was suprised how easy it removed them.


12- 0T203 STUD
3- 0T958 STUD
6- 1A3462 STUD
21- 1B4204 NUT

There are three different stud lengths for the cat ten head. 3 part no t-958, 12 t-203, and 6 1a3462. They are different lengths for just holding the head, hold the head and the sparkplug wire holed, and holding the head and the heat shield. There was a way to convert the old numbers to the new cat part numbers. I forget how though.

I do not know if they change up again but you would ask for 0T0203 for the T203 and 0T0958 for the T958
Thanks

Ken,
That is the way to change the part numbers! Thanks for reminding me!

McMasterCarr carries all kinds of studs just need to know the size and length

If you want the combination fine and coarse thread grade 8 studs you will have to go to Dorman products.

I am curious about the length and diameter of these. Can any of you tell me the lengths and diameter?
Thanks,
