Rusted block on Case 300

[IanCA]

I finally got a chance to take a look at the Case 300 I was given. The motor is free but the galley on the carburetor side has rusted through and leaks water to the outside of the block.

Has anybody ever welded up something like this?

Probably not the best idea but I don't know how easy it will be to find another block. I am in the Sacramento, CA area if anyone has a block they would like to sell or knows of a tractor re-cycler that might have something.

After looking at the block some more and talking to a friend that knows this tractor he says it sounds like the water froze and the block cracked. He recomended brazing the crack.

Anyone have experience with this?

Thanks,

While brazing will work, it does not look pretty. What I prefer is to " pin " the crack. It is a matter of drilling into the crack and tapping it with a special tap and then screwing in the special tapperd bolt which will twist of nearly flush when tight. The end result looks like stitching and can be ground down smooth again. I have done this to three blocks and one head so far and it works great.It is important to drill the ends of the crack first as to not spread it when fixing it.

Beagle,
Did you get some type template or drill freehand?
Thanks,

Google "lock-n-stitch".

My brother has used this method successful. He actually joined a casting broken completely apart and has held on the hitch on his Allis Chalmers. This repair when done will actually pull the metal together.

The kit somes with special drill and tap and a template for drilling the holes. Also instructions for using the kit... Gene

I just free hand it drilling each hole so each screw will overlap about half way, it kinda looks like this when your done ))))))))). It sounds scary and difficult but a 3 inch crack only takes about 45 minutes to fix.I put locktite on each screw for a sealant.
