clutch issue

[Jim Becker]

At this point I have to ask, are you SURE it is leaking at that head bolt, not leaking somewhere else and running there?

I looked hard for a crack but it’s wet around that bolt and runs down around the two plugs on either side of it. I don’t actually see it coming out though.
If it is a crack I’ll open it up and either weld it or JBweld it.

Coolant leaking from the upper radiator hose area will accumulate in the spark plug recesses.

It’s on the other end of the head.

I should read more carefully.

Warm the tractor up until all coolant has evaporated.

Sprinkle some white power, talcum or flour, across the head. Check for moisture every so often, 30 minutes - - hour. The seep will show up as a wet spot.

Hopefully the rtv will do it but if not and I haven’t had an aneurism I’ll give it a try.

After dropping one of my girls off for work I went straight from the truck to the barn. That's how much this has been bugging me.
Refilled the radiator, fired it up and watched close for a leak. It's there and it came faster this time.
It's not the bolt, it's a crack in the head. Damn.
There are squared off areas on top of the head. I don't know if that line is the way its cast or a crack but now its looking like its a crack or both.

The comment I made in the video was made after I thought I turned off the camera. There was about 6 minutes of video of me quietly draining the coolant again (beginning to hate that word "again") those were the only words spoken.
So, I don't have the time right now to fix this properly with a head swap, because we know all to well that it won;t be that simple and I'll end up doing a lot of other stuff. I'm considering cutting open the crack and filling it with JBweld hoping that will buy me some time.
I need to get back to the clutch, fix that and get this out of my shop.
You think I've got half a chance of that working?
If so I'll do a proper repair down the road.

I would think the JB would be at least a good temporary fix unless the crack extends into one of the head bolt holes.

Ill say it "seems" to be flat and running about a 3/8" above the bolt head. I said "it seems" because This thing is doing a pretty good job of playing with "my" head. I'll grab some lunch and then go out and delicately cut a little pocket into the crack, clean it with solvent and fill it with JBweld.
I need to get back to and finish my pickup project which has been extensive.
It's been one that I started and as I went found issue after Issue repairing each one as I went.
This is the reason I don't want to get too deep in the cub right now because I'm afraid of starting another marathon project.
This represents the very tip of the iceberg and it needs to be finished but I refuse to ignore things that need to be made right.
I think I'm hopeless.

Thats a clean looking truck!

Now ya, you can see a little rust in the bottom of the door but in this shot I had already welded new metal in place of the rockers and cab corners.
The rear frame straightened, rot cut out, new metal welded in, reinforced, stripped and painted. The list of new parts just goes and goes... and all by my hand. Even stripped, polished and painted the wheels.
like I said, I’m hopeless

Nothing wrong with making things better for yourself!

With all these projects stacked up I'm not sure if I am.

Ok, I hit it with the diegrinder and the crack is obvious now...



It was a little tricky getting a cut off wheel in there to open up the crack but I think I got enough to give the epoxy some purchase...



I had this on hand to repair a gas tank that had pin holes around the filler neck weld and it worked amazingly well.
There's no real pressure to the water jacket in the head so it should work (?), we'll see...



it's supposed to set up in an hour. I'll wait till tomorrow to be certain...
Wish me luck.

[SamsFarm]

I did one like that too.....

Looks like is could be the same spot!

Did you grind further to each side than in your pic?

When I zoom in it looks like the crack extends further on both sides of your grind job!

I hope you got it all!

[Lt.Mike]

Yes I saw that too but didn’t want to follow it too far for fear of lifting it off and I’m gambling it’s past the waterjacket. I carved about a 1/2” to either side of the leak . Tomorrow I’ll refill it and fire it up. If it doesn’t leak I’ll move on to the clutch. If it does I cut and fill till either I get it or it’s a lost cause.
