1602d Tractor Remote Hydraulics?

[project_X]

I want to add a set of rear remotes on my tractor. It has had the pressure line cut for the loader (as most of the grey markets are done) and there is no power beyond sleeve on the loader valve.

I was reading many threads, and came across this one http://www.tractorbynet.com/forums/yanmar/43657-remote-hydraulics.html

I can find the correct ports, but the manual I have (from a Domestic YM226) says I need a headless plug (1/4-18NPTF) to block the path, I believe that the grey markets use BSPT threads in this block. Does anyone know what size plug I might need? And the BSPT thread size for adapter to this block?

You can see the 'O' for outlet on the lower left of this picture

and the 'I' in the middle for inlet this picture.

Here is a plug. However a npt plug is only 1 thread different per inch and would probably work. MSC Item Detail I sure don't know what size your larger plugs are but not sure they aren't 3/4-16 straight thread with a gasket behind them. I installed a single acting cylinder port on my 2002 where your plug is on the right side in your 2nd picture. I drilled and tapped the plug for 1/8npt and re used it. Here is a picture of it for what it is worth. This won't work for your logsplitter. The hose you see on the other side of it is actually a hose making a loop where you are wanting to tap in. If your fittings are bpt look in this area. Browse the MSC Big Book Hope some of this makes sense to you.

I took the plugs in to a local hydraulic shop to get fittings, they were measured to be 3/8" BSPP.

In the attached picture I have labelled the parts, I have circled a part in blue, does anyone know what that part is? There seems to be a long spring in it?

I think it must be the pressure relief valve

Anyone?

I'm assuming the headless plug must be 1/4" BSPP.

Yes, that is the main relief valve cap. Did the hydraulic shop have the BSP fittings? I am pretty confident this is a gasket you may find behind your plugs. http://www.hoyetractor.com/mm5/merc...=HTE&Product_Code=23414-170022&Category_Code= My ym2002 parts book shows I have 3/8" plugs also and shows this part number for the gasket behind the plug. (23414-170022) The 17 in the parts descrption is for 17mm or .669". The od of 3/8" pipe is .675". You are probably tired of me rattling here but another thought has struck me. There are bspt (tapered pipe threads) and bspp (straight threads) which may be what you have since it is sealed with a gasket. If so this would be the fitting you would want if running 3/8" hose. 7002-06-06 http://www.royalsupply.com/store/pc...6-06-3-8-MJ-3-8-MBSPP-Straight-2977p53349.htm You can type that part # in google and get bookoo hits. If you want the tapered fitting type in 7000-06-06.

The shop had everything I needed in stock, except the 1/4" BSPT headless plug. The JIC-6 to BSPP 3/8" is exactly the part I used.
They can order the headless plug in, so i will order that tomorrow.

Hope all of this works out for you. Be sure and give us some feedback once you have used your new outlets. Still thinking you may put a little back pressure on your loader valve. Personally I don't think it is going to affect you but according to the hydraulic gurus it possibly could. :thumbsup: One more thought. Assuming you are going to have quick disconnects on this circuit am I right that you will have to have a short hose to complete this circuit when not hooked up to splitter or whatever?

I'm putting an open center 2 spool valve fixed to the tractor. The QD's will be on the valve to attach to cylinders.

On the tractor IN will connect to PBY on the new valve
OUT will connect to IN on the new valve
And the OUT on the new valve to the side of the reservoir on the tractor. This wayu the fluid will cycle back to the hydraulic system even when the QD's aren't connected.

I don't think there should be any more pressure on the loader valve than when I currently use the 3-pt hitch...
Wondering aloud, could one put a check valve of some sort on the OUT of the loader valve to protect it?

"Wondering aloud, could one put a check valve of some sort on the OUT of the loader valve to protect it?"
Makes me wonder too! Hmmmm. Don't think it would help because you are going to have whatever pressure you are demanding at the new valve passing through the loader valve anyway. If you are requiring 1600psi at the new valve then 1600psi will be passing through the loader valve. At least that is the way I see it.
