This job was more difficult than most realise. Well done.
-
The thing that fascinates me about cutting threads is how the machine is able to do it without cross-threading. I know the machine is designed to do just that, but I still find it cool.
-
The champer on the end of the rod allows the seals to slide onto the rod without damaging them.
-
Banana units and various styles of screws. Making life easier.

I have seen lots of YouTube videos doing this same basic repair of replacing the cylinder rod. Everyone has there own technique so it’s interesting to see slightly different ways to accomplish the same repair. Yours was not full of excessive talking. Just head down doing the job. Great video.
-
Just FYI the chamfer on the shaft is to avoid damaging the seals in the packing gland during install. Great job and thanks for sharing.

Nice job welding the shaft
-
I log now however I used to work in a machine shop for about 6 years. I have a few machines and I’m not a bad machinist however thank you for posting this video I learned a few things that I found very valuable. Thanks again for posting

Might consider center drilling the pin eye first thing. Running a center steadies things and provides a nice line up aid when putting new rod on.
-
I now thread on the lathe with the carriage going away from the chuck. Much easier and safer, I just had to order an LH threading holder as it's flipped upside down now. Got the idea from Joe Pie as he has a great video on this..
-
Nice one . It's good when it's not the induction hardened stuff ! Cheers .
-
What a nice job. Your experience speaks volumes 👍🙂👌

I would cut threads first. Incase the first go gets buggered, you may get another chance before you need to need to cut overall length and bore for the spigot which is much harder to bugger that up.

Awesomeness

When you tighten on hydraulic piston rod with soft pads, use a four jaw chuck....Keeps everything concentric....When you weld on the rod ...use some Stainless steel .020 shim stock around the rod is better ,not paper. You can use the shim stock it many times... All it takes is one time for "splatter" from the weld will damage that rod. I have done thousands of cylinder repairs. Hope this will help....

Thanks for sharing!

Josh, if you are in need, CRC Distribution in Alabama stocks many parts for hydraulic repairs.

If that cylinder doesn't have damage to the guide / piston / wall it would be nothing short of a miracle .
-
