Cracked Styled A Block

Peter IHCATJD · Nov 29, 2015

Hey all, I'm new around here and I need help. I have a 1948 Styled A, S/N 603***, and the machine shop says my block is cracked on the
bottom, and will leak coolant out on the ground. The block is pretty hammered, had a lot of ridge and now this. I'd like to find a new block
for it, P/N A3462R, unless you guys think something like stop leak or brazing would work (it can't be pinned). I restored a Farmall in high
school and rebuilt a Cat motor, but this JD has been in the shop for over three years without much progress. Anything you can help me with is
appreciated, Thanks.

I have veed them and brazed the cracks after they had been froze. As long as the crack is not in a cylinder, it should work.

"Block stitching" should do it by the right person who knows stitching. Ask around in your area, machine shops etc.... Where are you from ? A guy here in Massachusetts does it.

That's what I meant by pinning, the metal is too thin they said. I'm on the Central Coast of California.

Contact LOCK-N-STITCH in Ca. web online. They can do thin castings.

Depending on where the crack is I would think about a different block. Here in the Midwest there were a lot of those A's so parts aren't real hard to find. I have three right now and know they're not cracked but may need to be bored.

I will look at the parts "A" I have and see if the block number matches. If so - would you be interested in buying the block and having it shipped to you?

I am in Hershey, Nebraska -- Zip is 69143 if you want to chrck out shipping costs

There isnt any amount of trusting a lock n stitch over a used block. There hundreds to be baought for the price of "fixing" your old cracked block. Buy a different block and go down the field/road.

We started this out by talking of the best way to repair the block. I would look for a used block first also. But if I was going to have to repair it, I would use the Lock-N-Stitch method and pressure test it.The one type they use is more than just pinning. I was in the engine rebuilding business in central Illinois for 40 plus years. I would not try to repair a block or head if I didn't think I could guarantee it.

I checked the block on my parts tractor - the block casting is A3472R Send me an email if you need to know more.

Sorry! The block number should have read A3462R !!!! Dang fingers get in the way of spelling!

Thanks everyone for your help, I've gotten a few offers for replacements, if the place in Turlock can't help me, I'll get a replacement from you guys. Thanks again!
