Farmall H,broke bolts in water jacket cover

[[email protected]]

Best way to remove broken bolts from water jacket cover. I tried to remove two and bolt heads broke off both. Its a 1947 H probable never been out. Two are behind the exhaust manifold, really dread those.

Don't dread them, take the Intake/Exhaust and carburetor all off together. Squirt some penetrating oil on the manifold bolts, set your air wrench to the weak side, chatter on them a bit,if they got the tall brass nuts or tall steel bolts shouldn't be a problem. Now the water jacket bolts thats a different matter. I might get some disagreement but the block is cast iron. the bolts are steel, they melt at two different temperture, what i do is use the torch and melt the old bolts till their molten metal, Help pick it out of their with a screwdriver, or a pick,
or a small chisel,chances are you can use the original threads. Incidently take the gas line off too, and threw a old moving blanket over the gas tank and sediment bowl area.

I have always had good luck at welding a nut on the broken bolt. The heat of welding breaks the rust seal and they usually beck out easily. This works even if the bolt is broken off below the surface: the weld won't stick to the cast iron, you might lose a little cast but the threads are clean when you back out the bolt.

Thank you for the quick reply, no one thought drill and easyout would work. I dont have easy access to a welder or torch. what I was hoping was to drill them to a thin wall and heat them with a propane torch and use the easyout.Thanks again.

I did remove the water jacket cover, how to remove rust inside. There is a lot of rust from this length of time unopened. What should be done from here and how.

I just knocked the rust off with a wire brush & blew it out. My engine was apart for a rebuild though. Was able to clean all the rust out of the system. If you are working on a running tractor, you may just want to reattach the cover & flush out your system. Straight vinegar works good for that.

Make sure to use your favorite gasket sealer for the cover. They like to warp, over the years & leak.

Don't get all excited tightening down those bolts! You risk warping the cover (even more)!!

You can always drill it out and if necessary install a Heli-coil so you threads match up with the bolt. I have done this 1000's of times to fix broken bolts. You;ll have to buy a Heli-coil kit but it's a lot cheaper than braking an easy out off in the bolt. The are super hard metal and do NOT drill!!!!!!!!!! Also the drill bit so go slow and easy!!!!!!!

Left handed drill bits sometimes work remarkably well.

Pressure washer! Wrap some plastic around the carburetor if it is still in place and it concerns you, if it is still in place you are a glutton for punishment if you ask me.
Have you gotten the broken bolts out? If not I like Andy Martin’s method if you have a welder.
I applaud you on coming back after 11 years and replying to your original thread!! You my friend understand the value of a forum format that brings a thread back up to the top of the list when a new reply is made. Some of the guys on here seem to not be happy unless the subject being discussed is strung out into half a dozen different threads to maximize confusion.
Thank you!
