Machining & Welding - Rebuilding a Hydraulic Cylinder Rod, Manual Only Machine Shop

Broken cylinder rod? No problem. I just started getting more hydraulic work in and have been learning a ton about it. A couple little hickups along the way, but overall the customer is very happy with my repairs.

Watch as I make quick and easy work of this cylinder rod replacement.

Topper Machine LLC is an entirely manual machine shop located in Spooner, WI. Our videos will highlight some of our shop work as well as the sawmill we built in the shop and our A.D. Baker steam engine, and others we work on.

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.

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.

I envy you guys for the ability to figure out things and to solve mechanical tasks. Y'all's work really is inspiring.

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.

The taper on the stub end is to allow the rod seal not to be damaged when your sliding the packing gland on. I've been machining hydraulic replacement parts for more them 35 years. Those bobcat style rods are really simple and I end up doing a couple a week.

[Vernon-Chitlen]

That was slick, machining the stub on the boss and it fitting nicely into the rod. Made me smile with appreciation when I understood your plan. 👍

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.

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....

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

Nice one . It's good when it's not the induction hardened stuff ! Cheers .

Great work Josh, never seen the snow trick on a Machine tool 👍.
Yes, the friction welded flash curl can be quite hard, depending on material grade and to a lesser extent friction welding parameters.
Thanks for sharing

Nice job Josh, I do alot of jack repair , great video, keep'um coming..

[benjurqunov]

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.

[scottkinkead]

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

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

Great job. This was really enjoyable to watch and I learn so much from your videos, thanks
