Is this an issue?

Will the fact this bolt hole in the head is missing part of the top surface. There are no cracks, just the missing section. Will I be able to torque this nut correctly?

I do not think it will be a problem,
do you have thick flat washers that go between the bolt heads and the top of the motor head.

if so you are good, if not I believe I would place a flat washer under the bolt head on this one, you not want the head cracking out any further.

I'd build that back up with weld or by brazing. It's easy enough to do, so why risk further damage? I'm not much of a welder but I'd have no problem clamping a washer in place with a bolt through and filling the gap with brass.

Welding that hole up would be a bad idea.
Brazing it would be worse.
Put a grade 8 washer on it and torque it down.
If the head fails they are cheap and plentiful so find another one.
They are very easy to change - no valves to reset, no manifolds or thermostat housing to mess with, etc.

If this was a running tractor before you pulled the head I don't think it would be a problem. looks like it's been like that a long time some one even painted it with that chunk missing.

Id try torquing it down with a washer first. I would be also leary of welding or brazing in that localized spot and I dont think its necessary. It shouldnt be a problem.

Gary, if you are concerned, I have a good head. I am just se of Portland.

Yup.. I'd try a good fitting gr8 flat washer on that one too.

I would use a hardened flat washer on it,torque to specs and fill it with JB weld.Make sure you clean the area around the chipped out piece good before you seal it.

souNdguy · Jan 9, 2017

the jb weld will do -0- for a bolt.

for a stud, it might even make it harder to pull the head next time.

Well it seems I'm in the minority here, like the only one lol. It's kinda lonely but I'm always willing to learn. When I looked at the photo last night it looked like half of the bearing surface was gone. Zooming in today after reading the other comments I'd say it's maybe missing 25%. What would be the concern with filling it? Distortion? Starting a crack? Both possibilities I suppose. I agree that JB Weld would be of no value.

I would have no problem using a washer under the nut / bolt .

If I were doing a total rebuild to last the rest of my lifetime it would always bug me knowing its there . If I were patching one up just to work the snot out of it I would have no hesitation using that head .

I can not count the number of parts that I have destroyed , broken , cracked , ect just trying to disassemble , remove , repair , etc . Luckily 99% were common inexpensive items and I have the experience to USUALLY keep from tearing up the good stuff

This would be a great learning experience for a do it your selfer . It is not a critical part as in if it fails it is not taking out lots of expensive parts also , It is not going to leave you stranded 500 miles away from home , or cause you to wreck going down the freeway at 70 mph .

Worst case is you screw up the head and have to get another one . As long as you know that going into the project , more power to you . Drill a hole for a temp sending unit while your working on it . :shock:

But it would look pretty!

Mike Groom · Jan 10, 2017

If you guys read my post I said torque to specs and fill with JB weld,I never implied any strength added,it would just look pretty when you paint it.It would function fine either way.

Amen and Amen ---case closed -- done deal..

Gary (Or) · Jan 11, 2017

This is from a tractor that hasn't run in many years plan to make a worker out of it, so the answer is a flat washer.
Anyone that would notice that little section missing is looking way too close.

Thanks Everyone
