Log splitter ram

[IROCZ28l9841u]

So I am having to rebuild my long splitter for the 2nd time. My ram has ports that are blocked off on the top of the ram. I'm wondering if I can hook bathe hydraulic lines up to those ports instead of the ones on the side of the ram.

Most likely the extra ports are there for the very reason you are wanting to use them. I have seen lots of tierod cyl with two sets of ports.

Could be a cushion port....

What would a cushion port be used for.

 

[JeffHK454]

A passage machined into the endcap that reduces flow at the end of the stroke and softens the "clunk" you feel and the shock the system sees. That plug might just be a cap put in to block the port end.

Oh. Ok. So if it is just an end cap for the cushion port how would I go about finding that out

 

[JeffHK454]

Usually under the plug the hole I.D will reduce in dia. down to 1/8"-3/16". But without a scamatic of whats going on in the endcap and the rod end its hard to know really what you've got. Most times the plug you're pic is shows is a cap for machining access.

If you just want to reposition the outlet to the top just turn your end cap 1/4 dosen't matter which way it is installed!!!!!!!!!!

you didnt notice the position of the mounting points did you. My guess the reason for wanting to move the hose position is because this cyl mounts by a flange on the same side as the hose port. As for the cushion port. could be considering this doesnt seem to be a usual configured cyl, based off the mounting points. To check, just remove the plug and look inside. If it has springs and check under the plug then it isnt just a normal open port. If there isnt anything under the plug and the port is the same size as the port currently being used for hose connections then I would just swap out the plug with the fitting and it would be a done deal.

Yes Turing the caps will not work. And I will check the plug tonight or tomorrow. Thanks for your help

Like what muddstopper said..some have a check valve type flow reducer while others use a small protrusion on the end of the ram that fits into a machined counterbore on the inside of the end cap. When the protrusion enters the bore it diverts the oil from going directly out the normal port and forces it in a secondary circuit with much lower flow capabilities.

I hope that made a little sense , I struggled trying to put that into words.

 

[IROCZ28l9841u]

Yes it makes sense. I have to take that plug off and inspect the hole

I'm almost positive it's a cushion port. The thread size is a lot smaller than the line on the side.
