I have to replace the head on my H...it has cracked at the coolant drain plug boss. The tractor runs great and I don't want to get into more of project than necessary..but what else should I do during this project? What should I do to the replacement head to get it ready? I've read on this forum that exhaust studs are almost guaranteed to break off...but since this head is junk should I still cut them off? Thanks for your help.

I agree with WILL. K-D block sealer is pretty good stuff and your crack is in an area where the leak is totally external. It sure is worth a try for a few bucks. I have crack it the head of my D under a valve seat and it held for two years under some pretty hard work. It probably would still be OK but I think the crack spread. Welding is another option, but I'm not sure how good you can do without removing the head to pre-heat it. I had the head on my A fixed 20 years ago by plugging it with cast iron tapered screw type plugs and it's still fine. That would probably work good too, and you could do it on the tractor if you don't mind a few drill shavings in your hair. You might have to re-tap the drain plug hole. Good luck, Paul

HOW BAD IS THE CRACK, DID YOU TRY ANY STOP LEAK ON THE TRACTOR. THE PARTS STORES LIKE NAPA HAS SOME REALY GOOD STOP LEAK. THE HEAD ALSO CAN BE WELDED AND SOME TIME RIGHT ON THE TRACTOR. I HAVE FIX ALOT OF HEADS THAT HAVE BEEN CRACKED THERE. IF IT IS,NT LEAKING IN THE MOTOR OIL OR PISTON BORE. I WOULD TRY ANYTHING BEFORE REMOVING THE HEAD BECAUSE OF HOW IT RUNS.ALOT OF WELDING SHOPS CAN FIX THIS. LET US KNOW. WILL

The cracks are quite severe. The drain plug was frozen and the act of removing it, despite multiple levels of caution, broke the cast iron boss at the drain plug. So, I think I need to replace the head. Thanks for your suggestions though.

Will - I went ahead and removed the head last night. Originally I was figuring to replace the whole head but now I'm considering trying to repair the cracks. There are 3 cracks, 90 degrees apart..starting at the top of the drain boss and extending down about 1-1/2" down the side of the head..so that one whole chunk of the head is loose. I'm not a welder but might find somebody locally; or have considered JB Weld. Send me an e-mail and I will mail you a photo. Thanks for your help.

I found one head for $150 and another for $200, "as is" with broke-off studs, etc. I also found a completely re-built head, complete with valves and springs, for $395. I'm proceeding with taking the head off my tractor but haven't decided whether to try to repair it or just replace it...my inclination is replace it.

Don

The price of $395 for a rebuilt head isn't bad at all. However, you are taking someone else's word for the quality of the work done. It all depends on who you buy it from. A stripped head for $150 or $200 isn't bad either. If you buy one of these heads insist that the seller have the head magnafluxed, or give you a return if you have it magnafluxed and it is cracked. This will insure that you aren't stuck with another cracked head. Other costs include: cleaning, re-surfacing, and reassembly. It also depends on the condition of your valvetrain in the old head. Certainly install new hardened valve seats. It's probably a good idea to install new valve guides, so while you're at it, you might as well spend the bucks on new valves too. It is very easy to get caught in the domino effect of repair and restoration but is also senseless to install a worn part in a new head. Just make sure that you don't look at the cylinder walls when you remove the head or you'll probably end up tearing into that too! Talk to a local machine shop and get prices on building up the bare head. Then you can really compare apples to apples! I rebuilt the engine on my father-in-law's 1939 H, so feel free to ask any questions. Have fun!

THAT SOUNDS LIKE A FAIR PRICE FOR A REBUIT HEAD AND ALL YOU HAVE TO DO IS PUT IT ON. HAVE FUN WITH THE H. I HAVE THREE OF THEM AND THERE JUST FUN TO WORK WITH AND PLAY AROUND WITH. WILL
