And thread returned to topic (although I completely agree with NEVER USE TEFLON TAPE ON HYDRAULICS)

Update on my CCM top link cylinder... Everything went per plan and the double piloted check vavle is the ticket. Set the ram position and it don't move no more. rural2 likes! BTW, in my case the teflon tape info was appropriate and needed. Thanks.

So how does the check valve work? Do you have to press a button or something to move it again?

No buttons, all automatic. I would just be repeating the info from CCM so here it is: Hydraulic top link, Top-N-Tilt, Side link
I already had a tilt cylinder without the additional check valve and it is not staying where I put it, trying to figure out a way to install a dpcv on it also.

NEVER use teflon tape on hydraulics. Never use teflon tape on hydraulics. It works OK on the first use, but can later end up floating around your system and blocking a valve or port, especially if you rework anything. Most manufacturers will not warrantee hydraulic components if teflon tape has been used. Instead use a pipe dope made for hydraulics, some have teflon added to the compound. Sorry to preach to you guys, most of us have heard this before, but it looked like it needed to be added again here...

Thanks jimgerken for the advice. I bought a tractor a couple of months ago and was thinking of adding a HTL. Teflon tape is exactly what I was going to use.

Anyone hack up an Lxx40 series Kubota to make tilt from the two external lift cylinders ?
Probably have to "liberate" the arms from their connection via the rock shaft, but that shouldn't be too hard for some of the folk on this forum (-:

Do you need to mount another hydraulic valve / lever, or do you use the implement raise / lower lever? If you added a lever, where did you mount it?
Thanks and Best Regards

I've been using mine for a few weeks now. Getting the threads sealed is important - don't go cheap with the teflon tape. Cylindar works like a champ - exactly what I needed.

It's not a check valve, it's a LOCK valve. It needs a couple hundred psi pressure to unlock. So, the fluid can't move unless you want it to.

A check valve counters the force of the load so that it won't open until the hydraulic pressure from the pump exceeds the pressure on the other side of the check. Otherwise, when you start to feather the load could overpower and drop.

It's just verbiage, but until you are exposed to the difference it probably makes no difference. But if you go and buy a check valve and expect a lock function - then it makes a difference!
