Stuck Head stud problems

[BenTheWheelHorseMan 43]

I have a Kohler k241 that I recently acquired. When I bought it I was told that it was rebuilt and bored .030 over. It came without head bolt and a head gasket, but there were 2 head studs in it. One came out relatively easily, but the other is pretty well stuck. I have tried penetrating oil and I do not want to heat it because it is right next to the exhaust valve. Would it be a big deal to just put a spacer on top of the place where the bolt head would go and just put a nut on it? Thanks

These are some pictures of the head and the stuck stud.

You should have no problems doing what you propose.Just make sure that there are a couple threads below your spacer top so that the nut bears on the spacer and not bottom out .Try to use a heavy walled spacer.Do the normal torque sequence and retorque after a few hours run time.JMHO ,JAinVA

Thanks Jim. I was hoping you would say that. That stud is really stuck and I am glad that the spacer should work out.

Is it possible that the stud once had a bracket also attached.

I was thinking some Kohler's had a bracket for the throttle cable attached under one of the head bolt/stud. Just thinking out loud.

[BenTheWheelHorseMan 43]

That could be. I recall having seen some like that before. I was really wondering if someone at some point switched the head out on it from the one that came with studs.

What is the K241 off of? I've never seen one with an oil dipstick tube. Does it have a starter that mounts on the side and engaged with the flywheel, or did it have a starter/generator? Could it be a stud for the mounting bracket of the S/G bracket?

The S/G uses 2 studs but they are on the back end of the head (away from the valves)

Kohler engines were widely used in applications other than garden tractors.They provided reliable power for many application such as concrete/mortar mixers,concrete saw and the list is endless.A year ago I was able to get a clean low hour K341.This engine has no throttle control.It is set up to run high idle.The block has 2 studs where a bracket is attached that has the ignition switch and starter switch.The starter switch looks like the old auto dimmer swtich.It doesn't engage a solenoid but directly closes the circuit between the battery and starter.This is a very handy set-up as the positive lead and fuel supply are the only things needed to mount this engine. Works great to evaluate a newly aqquired tractor with a blown or missing engine.To my original point.That Kohler could have come off just about anything. Luck,JAinVA

I believe it is off of a cub cadet because it has the starter generator mount on side. The guy I bought it from may have told me that it was off a cub cadet, I just can't remember.

Actually, I see that on the pto end of the engine there is the cub cadet front clutch mounting plate and starter belt pulley so it must have been off of a cub

If it makes you feel any better...last year I refreshed a tractor and it had a K241.  I took the head off and snapped that very bolt by the exhaust port.  After drilling the broken bolt out and cleaning up the threads, I bought a new stud, coated it liberally with hi temp JB weld and threaded it in and gently torqued it into the block but not enough to strip the fragile threads.  I let the JB weld set for a few days, reassembled the head and torqued per factory specs.  Still runs like a champ.  Leave the stud alone and make sure the head is thick enough so you can torque down on the nut
