 Topic: Welding a cracked blockPosted: November-13-2013 at 2:06pm |

I remember when Steve was considering having a cracked manifold repaired Someone recommended a shop that does this, I believe it was Pete. A friend of mine is restoring his grandfaters Ford 9N tractor and discovered a crack in the block that extends into the water jacket. Any suggestions are appreciated.

Go to a certified weld shop. They will have to pre-heat, use a nickel rod, then post heat. After all this heat it may need to be rebored to true it up.
Isn't there a junk yard that you can get an old block to refurbish? I think that would be a better path in the long run, JMO. |

Don't think you'll find to many blocks for one of these.

I think it was these guy's
And you might be surprised Paul, not more than 10 years ago there was 1 guy about 16 miles and another about 25 away from me who worked and parted out 9,2 and 8n Fords. Quite alot of them were made and still around. Much like CC's, quite the cult around old tractors. While the old JD's are popular these series Fords are still quite useful and New Holland dealers still have parts. Case has parts for IH's too and there are several web sites for them and part places too,some that have had parts remade also. |

Thanks for the answers.
There are a few of these blocks around but many of them are in unknown condition and may have cracks. You never know until it is magnafluxed. I have worked on these engines a bit. They were used in the Ford GP prototype and a few other applications. I believe he may want to save this one because it belonged to his grandfather, but I'm not sure. I will check with him tonight. This is the tractor  here is the Ford GP I have maintained for a friend with a 9N engine  This guy is in the Military Vehicle Preservation Association (MVPA) with me. He goes for some of the more unusual vehicles. Here is one of his fire trucks.

Thats a 8n John,you can tell by the back wheels and floor boards. The 9 that Paul linked has after market floor boards and above them you can see the foot pegs. You can also see the rear axle and drums are different. Your friend is lucky,he has the original rear wheels which usually rust out from the calcium chloride used to add weight. They were welded up from 2 pieces and would trap the mixture when it leaked out. That one is actually newer than mine,it has the Ford script on the fenders. Mine was the 2227 made is low considering how Ford cranked things out

Hmmmm, he called it a 9N. I wonder if it was a typo? This one was abandoned by his grandfather in a silo for many years before he pulled it out and started working on it. It runs but has a very small crack / leak. He uses it on his farm / wildlife refuge, it is not intended to be a show tractor. He does take very good care of his stuff. He uses the fire truck in the photo for prairie restoration burn control so it is still a working fire truck.

Gary, your eye for detail has very good acuity. I assumed it was the Ford tractor I was familiar with. You know what that gets you. I got this email to clarify:
I bought a 9n as well with a rototiller which needs the Howard reducer in the rear end and the Sherman in front of the tranny. This is the crack.

Looks like an 8N to me also. We rebuilt one several years back including a complete overhaul of the engine. On the 9N the distribute risk in front of the engine and on the side for the 8N, also I think the 9 was only a three speed whereas the 8 a 4 speed. They are iconic.

John, are you after a "no show" repair?
If not a local shop may be able to do this. I have a mid 50's IH/Farmall Super C that I've owned since the early 90's. It had a crack in the block repaired when I bought it and has not been a problem. Looks like it was brazed. |

I know many may think of this as a "hack"
but i have had great luck repairing cracks in engine blocks similar to this by chamfering the crack then filling with a metal re enforced epoxy I have several motors with more than 3 seasons of use on them still running great with no leaks I actually used this method to repair a cracked exhaust manifold on my 84 sn2001 |
