Don't scrap it, JB it! The saying holds true again.

Came across this while looking for how to straighten my bent hydraulic rod. I used your same idea to fill the swivel joints on a Series 2A Land Rover years back. Works a treat, so good luck to you, should get a few more years no problem.

I used JB Weld to fill 4 deep scores made by the wrist pin in the cylinder walls after total piston destruction. I used a propane bottle torch to burn out any oil first. The I used the acetone. I finished up the "repair" the same way you did and slammed the engine back together. I put 15, 000 miles on that engine without burning a drop of oil. I believe the repaire would have lasted much longer than that. Upon the teardown of the engine, due to a different piston shaddering. I found the JB Weld was still very much in tact and no signs of degradation. I reasonably suspect since the JB Weld was well below the combustion chamber. And well above any point of prolonged oil exposure. Would be the largest contributing factors of its success. Also the cylinder was not broken. Which would have caused the repair to fail in a short period of time. Oh, just for reference sake. The engine was a 4.0L and is still currently installed in my 2003 Jeep. The piston skirts are known for breaking off around 225, 000 miles. After the second piston exploded. I completely rebuilt the engine. And I had the cylinders cut out and replaced too. So unfortunately I cannot see how long the JB Weld would have lasted. Sorry.

Thanks.

I watch the video on how to straighten a cylinder shaft I used your technic on a servo 8000 log loader stabilizer it has 20 degree bend it worked well a bit scary but take your time and it works saved me 900.00 dollars.

I bought a 1966 ck 530 188 case Diesel Backhoe for $2500.00 I had the same problem like you got going but I don't have nicks I've got rust spots I'm going to wire brush those spots and rubs some hard grease on the chrome rod

Devcon makes a metal rich epoxy that repairs damaged shafts very well. Keith Fenner has some great videos on here on how to straighten bent shafts to a very high standard.

I'm going to tray this on a my pitted Western Snow Plow cylinder. I Can't find a new one easily.

Sir which type of jb weld are you using ?

omkarkore

Looks pretty good. Any use on it yet? How is it holding up?

Nice job. How's that seal holding up?

Hi everyone! Can I take the other end of my Ford backhoes cylinder off??

I have 60`s 4500 backhoe. I was unlucky and stupid enough and got the crawl-cylinder rod to bend pretty badly. Wise move might have been to just buy a new cylinder, because in my country inch-measured repairs just don´t exist. Well apparently I am not very wise man. I got a new straight rod from a local one of a kind Ford backhoe -lunatic (great guy!) and other parts (I don´t know english terms to them) were made (turned) just for me. (The end price wasn`t that gigantic.)
The problem is that also the tube got hit in the accident. There are few scratches inside. I planned to "JB-weld" them. Unlucky enough, the scratches are in the "deep end" of the tube. Am I able to take that end off of the tube??? It would be very much easier to do the job from that end.

Thank you for your reply (anyone who knows the answer, is welcome to give advice:)
