Is it hard to install jd harline kit for scv myself?

[JD 4520]

Thanks for the response. Next related question ... What is the best way to insure that the pressure is relieved from the hydraulics before disconnecting a line? I want to avoid a surprise.

With the tractor off and loader on the ground just push forward / backward and side to side on the stick and it will releive all the pressure.

Is the 3rd SCV already installed on your tractor? I read it as you are only installing the hardline kit, is that correct?

I am installing the 3rd SCV and hard line kit both. It all looks fairly simple other than all of the removal of tire and fender but just time.

I put on both kits and here to tell you there was no need to remove wheel or fender! Easy install and well worth it!

However the instruction do not say anything about the tire only remove the finder.

Maybe my model requires both be removed for easier access since it's smaller than your rig.

If the 4520 is anything like my 4200, the 3rd SCV spool is part of the 1st & 2nd SCV valve body used to power the loader. All the 3rd SCV kit consists of then is hardlines and a way to actuate the spool.

The 3rd SCV for the 4520 comes in two kits. The control and assembly for the 3rd SCV and separate from the line kit. The reason is they are independent. If you only need a 3rd SCV for the rear, you probably don't need the line kit for the front or you can design and make your own line kit for your application or perhaps cost benefit. For me, it was easiest to purchase from Deere both kits and have a tight fit and all the parts needed.

I just installed a 3 SCV kit.I will use the scv mainly to run a top link on my 2011 JD 4120. I found the information in this section, of this site of great valuable. I found no reason to remove the tire from the tractor. Thanks for all the information.

For a loader , there are better ways to control a loader than tying up the SCV ports and valves.
Just purchase a proper closed center joystick for the loader. Then tie into the high pressure supply line to the rockshaft / SCV valves with a simple T. Then return the oil with a t into the line from the scv's down to the transmission. Or use a ported filter cover.
Using scv's just wears them out and make them leak.big $$$ to repair. Loader joy sticks are cheap.

How will a closed center valve work correctly on this type hyd pump???? I think later model JD CUT's are open-center not closed-center hyd's. On a lot of JD utility model tractors rear remotes(scv's) is JD's only loader control OPTION.
