Hydraulic top link issues

[downsizingnow48]

Would top link cyl diameter have an effect on this problem? I have no idea but could be another variable.

Yes it could. I use rather large cylinders so require more fluid to complete an action.

I checked a restrictor in my hydraulic side link. A 1/4'' bit would not fit but a "C" drill bit would which is .242."

No restrictor there, that is simply a std sized port hole for many cylinders. I have had then from 5/32"- 3/8" on different cylinders.

To me for 3" and smaller dia cylinders, you have to be under .090 to really notice any difference at all.

Thank you very much for checking and posting the picture. :thumbsup:

I agree. No restrictor there.

We're talking about a hole the size of a round tooth pick or smaller.

^^ Thank you for that little gem up there. Would have never thought of that.

Thanks from me too LD. I disobeyed Brian and went with Kubota OEM valves for my remotes (all three with float). He warned me that some Kubota valves have a leaky history. And your example of the tilt cylinder "shifting" during hours of bushhogging is REAL. It is hard enough to get the bushhog nice and level with manual links. I really don't want to have to explain to the wife (chief bushogger) that she may need to occasionally trim the tilt.

So now I need to figure out what flow control (shutoff) valves to get (at least one) and how/where to mount them. How about a kit, Brian?

Set the side link and un-plug the hose from the rod end of the cylinder.

Done-rock solid.

That is dumb cylinders are made that way. Do they drill the hole in the cylinder small so it can be equipped with different bungs for different size fittings?

I don't know why, probably the same reason that the welds get done differently. Just how that particular company happens to do it.
