Let's take my live hydraulics to the next level

TOH helped me design a basic live hydraulics setup for my 8N using a front mounted pump and it has worked out well.

Now, I'd like to add some remote ports for a hydraulic top link and maybe add a hydraulic side link sometime in the future.

For now I would prefer to do just one valve and set of ports due to cost.

I understand that I will need a flow control but I am unsure of where inline this will go and the exact parts to use.

Would this be the correct valve?

And, would this be the correct divider valve?

what's your current pump gpm, pressure ( if a seperate relief in system ), plumbing routing and any other diverter or regulators already present?

hard to speculate on what you need, not knowing exactly what you got, and how you got it plumbed, including check valves if using them, etc..
 

I don't have an issue with upgrading the pump either if needed. This one could always be moved to the other 8n once I get it running.

If all you want is a low flow set of remotes suitable for a hydraulic top link you do not need any additional flow control. All you need is a control valve installed ahead of the test port/live hydraulics connection. The valve you linked is designed for a log splitter application and not well suited for the top link application. Use this instead:

Wolverine single spool DA control valve

If you think you might want more than one set of remotes buy the two spool version of that valve.

If you have an application that needs more than the 3 GPM flow your current pump produces you would need to add a larger pump, a flow divider AFTER the control valve, and an additional pickup and return line to the transmission sump. Your drive belt is also undersize for any significant increase in horsepower needed for the larger pump....

Would I need to split the discharge line from the pump to the valve and test port, or would I plumb from the power beyond port on the valve to the test port?

Technically you should use a power beyond valve but that complicates the plumbing. You can use a plain open center valve and run the pump to the IN on the valve and the OUT on the valve to the test port. Call or email me if you need the full story.

Looks like that valve has the option of going power beyond if you order the 2.99 plug. Really don't want to complicate the plumbing all that much though.

As far as the remote ports, what size should I go with? The valve has SAE 8 ports so I assume a 3/4" fitting.

Oh and as far as the top link itself, do I need to purchase one of these:

or, can I just use a basic double acting cylinder?

Seems like the valve would prevent the drift of the cylinder unless there was a leak in a hydraulic hose.

I need to measure the length of my current top link, but I was thinking something like this would work out ok. Just not sure if the rod diameter is the right size.

You are only moving 2 GPM max through the lines and in general considerably less so 1/4" hoses are more than adequate. I would use ones with JIC-6 swivel ends along with SAE-8 to JIC-6 port adapters on the valve.

A power beyond valve will have an additional dedicated tank return line for exhaust oil from the work ports and you would have to run that back to the sump - the transmission filler being my choice. The major reason for using a PB valve is that the tank return section off an open center valve is not rated for full pump pressure. If you check the specification sheets they average around 600 PSI maximum tank pressure. Sounds low but that is based on a 4X safety margin so on a 1600 PSI 3pt system it isn't all that bad and I have never had a problem with one. Certainly better than the iron pipe fittings the OEM's were using in the 50's ;-)

A simple DA cylinder will do the job as long as the seals in the control valve and cylinder are tight. By the time you find one the right size and with the right ends it may wind up costing just as much as the one made specifically for the toplink application.
