latest score - hydraulic cilinder

scons · Jun 12, 2016

Hi all,

I just scored an hydraulic cylinder for one of the items on my "tractor bucket list" : a wood splitter.

So far, so good, reasonable price but I have 2 questions/need advice:

What is the purpose of the box mounted on the cylinder ? I can find on the net that it is some kind of flow control valve. Does it needs to stay on the cylinder to make a splitter ?
The pin at the bottom is stuck, the deformed it already by hammering on it so there is a bulge on the end, have to grind that down. But what is the best way to get it loose ? WD40 ? Heat ? But will heat damage the inner bushing ?

Remember I am an hydraulic noob.

Counterbalance valve. No its not needed for a log splitter.

If you need to apply heat, extend the rod all the way. That will move the seals away from the heat.

WD40 isnt great for a penetrating lube. And since there is no plastic.......and possible heat involved so who cares about the paint, Would be a good application for Acetone/ATF mix. Mix it 50/50.

But yes, grind down the mushroomed part. If it was me, I would grind it all down flush with the bore. And probably spot drill it a little so a punch or whatever wont move around when being hammered on. Then take your pick.....hydrauluc press would be nice. BFH and punch, Air hammer, etc.
