Hydraulic Cylinder Pin Removal

Removing rusted pins from a Manitou MB26C tilt cylinders.

[@markrussell9719]

It’s a 60 ton hydraulic hollow cylinder made by Enerpac. I welded 1” threaded rod to the seized pin in order to pull it out as there is no access from the other side.

all-thread...that stuff is a lot tougher than it looks...!

Дальнаёбщик Мозгоёб yeah hand pump works

[@livetooextreme]

What are using to pump the jack? Link?

[@bendude6748]

seriously need to find one of these hydraulic cylinders

[@markrussell9719]

Hi thanks for the comment. Best place is eBay but they do hold their price.

[@dougankrum3328]

..Good Job...! I used to work in a machine shop that did lots of hydraulic stuff...cylinders would come in like this...sometimes the actual operating rod-end would be torched off due to guys not able to remove cylinder intact....storing equipment outdoors, un-covered...rain, and lack of a grease gun....? .I guess mechanics would torch the pins off...sometimes we had to actually bore out the cut off pins enough to collapse them, and them weld some beads inside to shrink them, or even bore out the remainder of the pin. Lots of this stuff from heavy equipment Rentals....

Doug Ankrum Hi Doug - Yes it did take some force to get out but managed to re-seal both cylinders as no damage to the rods.

[@jayhakim3524]

a two dollar tube of grease goes a long way...

[@bendude6748]

Got myself a 30T one off eBay for 180 quid brilliant tool to have

I must be dumb. I assumed that threaded rod passed back (leftwards in the video) through the hydraulic cylinder, and was welded to the pin. But when it finally came away, there was nothing sticking out of the yellow cylinder.

[@michaelnelson5816]

No you're right, that cylinder is hollow, he used the threaded rod that he welded to the pin to pull the seized pin out with that hollow cylinder

[@patdexter9188]

I liked to see you have a gauge on it so you know how much pressure your making! I've seen guys pull all thread in half before not realizing the oressure being exerted.

[@markrussell9719]

Hi Pat - To true that. A gauge gives a good indication of when to back off if things aren’t moving. Mark

[@genecoppedge5972]

Nice job, I know the feeling when that pin starts eating into your profits.

[@markrussell9719]

Indeed - thanks for the reply. 👍

[@mikemiller9119]

Thanks for the video

[@markrussell9719]

You’re welcome.

[@driveheronman4304]

Good job Mark 👍🇨🇮

[@lJUSTwanaCOMMENT]

Are those pins typically hardened?

[@markrussell9719]

no avail Yes they would be hardened.

[@wilmamcdermott3065]

Usally induction hardend

[@robertatwood2503]

Yeah that's the only flaw with that thing damn thing don't got enough stroke to it

[@genecoppedge5972]

Robert Atwood, short stroke? Yeah my problem too.

[@williamskelton8270]

Another trunion pin with no lubrication chanel's and another failed maintenance system.

[@rodhawkins5037]

That was handy dandy👍

[@libertyordeath1287]

What size rod did you weld to the pin. I have a 30 ton hollow ram and welded a 1" piece of all thread to the pin. The end result was I stretched the all thread until it broke. The pin did not budge.

[@markrussell9719]

I welded a one inch pin but grinded the end to a taper so as to get plenty of weld on there. I also heated the pin housing to a cherry red with oxy acetylene & then doused with a bucket of cold water to shock & release the rust.

[@Panostes]

Good job my friend.. I have a similar video on KZbin... I have made the puller ...

[@AlphaBobFloridaOverlord]

So much easier to tackle a job having first watched someone else take on a similar task - Thank You!

[@markrussell9719]

You’re welcome - Hope it was of some help.
