Newby welder with questions

[LS Tractor Owner]

Well, not quite a newby, but not very knowledgeable about welding..... My question is about altering / changing the ends of a hydraulic cylinder for a side link setup. I can find the correct size cylinder as far as bore and stroke, but I cannot find them with the correct ends. I would need to cut off the ends then weld a narrow (7/8"w x 5" long)clevis on the rod end and a cross tube on the cylinder end.

The cost of buying a pre-made or custom made side link is unaffordable for me. I can get the cylinder for around $60. The rest of the parts would come from cutting the factory parts from my tractor's stationary link. The prices I have been getting are from $450-$600, the only local hydraulic shop would charge $350 if I supplied all the parts, still out of my budget.....

I have a 200A stick welder, a 170A mig welder, and an acetylene torch. I can weld using all of them, but have only done little repair type welding and a little fabrication of small items. I can do "clean" beads.

Am I out of my league to attempt to do this? I have never welded on a cylinder. I have never taken one apart if that has to be done.

So, does the cylinder need to be disassembled? Can the end be welded on by doing a bunch of small spot welds / tack welds letting it cool in between welds?

The cylinder is a 2" bore, 4" stroke, 8" cylinder length.

Any and all comments, suggestions, tips, or instructions would be greatly appreciated!

The cylinder does need to be disassembled. Bevel all the joints so you can get good penetration.

Does it have to be welded,
can bolt or pin on adapters be used in the existing cylinder ends.
If your cylinder has clevis ends an eye welded to the tube for the top,
for the lower end a pair of flat bars with a spacer for width through the clevis end.

I have made several hydraulic side links without taking the cylinder apart...it is NOT necessary...

Open the port on the sealed end and extend the rod out to the max...wrap the end of the cylinder with a wet rag...just take your time and once the new end is tacked in place take it even slower...start the finish bead and then stop and let it cool down...refresh the wet rag and repeat the process until it fully welded...I have never had a problem with this technique...
...blowing air into the open port will help cool it down more quickly between welds...just take your time..

Cool! This is exactly the response I was hoping for! I can definitely muster up the patience to do it slowly. Which process would you use? Mig or Stick?

The ones I have made I used MIG...BTW...There are several other (old) threads where the process is discussed and where I learned it from...

Here is a pic of the 3 point, if you look at the top of the side link, there is a weird swivel type link that the link fits around. The clevis of the link is
1 3/8" Wide, with a 5/8" pin. The cylinder I was looking at has a clevis that is 1 1/4" wide... no big deal, I could grind down the Link swivel, but the pin Hole on the cylinder is 1", so Reducer bushings would be needed on both sides of the cylinder clevis.

It would be difficult to re-make the swivel with a 5/8" pin at the top and a 1" ID tube for the pin on the bottom.

That's why I was just going to cut the top off of the left lift link and reweld it onto the cylinder. If you have any ideas after looking at the pic, please let me know... thanks

I never have any success using the search bar on the main page.... always gives me a hundred threads that barely talk about what I'm looking for.... any specific wording for the search?

I'll give it a try under "welding hydraulic cylinder ".... thanks

I thought about using just a pin through the lift arm, using a cylinder with a ball swivel, but that would put all the stresses on just one side of the arm. Also not knowing if I could even get enough swivel from a ball end on the cylinder. Thoughts?
