I seem to have broken the head stud off just above the jam nut on my 1450 Cub Cadet. The muffler rotted and broke loose from the exhaust pipe and it broke the stud. My question is, can I remove the stud and install the new stud and torque it to specs or should I loosen all of the head bolts and retorque them all when installing the stud. The jam nut is still tight on the broken stud and the head gasket isn't leaking.

I would think you could change the one without an issue. Just be sure to check it again after some run time.

IF it were me, I wouldn't run it until I replaced the head bolt and torqued it, then run it for a little bit and redo the torque as stated before. I would also have a new head gasket on hand incase that didn't last.

Thanks fellas. I'll throw the new stud in with the proper torque and see what it does. Since the gasket wasn't leaking I figured that it might be ok, but I wanted a second opinion. Thanks again.

You should be fine.

I am glad that Hotsoup brought this to light. Now as mgps13 mentioned, what would be the proper procedure to replace the washers without compromising a good head gasket seal or the integrity of your head. Could you just replace and re-tighten each stud at a time?
