sorry to keep bringing this up again. but we bought a shop manual for it and still cant figure out which plug does what. we were hoping that someone could tell us which one is which - we have them lettered. my guess is that E and F are not what we are looking at. if it is a plug that we did not label, we will label it for ID.
so here goes with the pic, again. we are going to hook this up to a 3-spool valve, one with float, so that we can operate the lift arms, bucket curl, and bale hugger or silage grab completely independant of implements on the back. if you need more info, just ask and i will try to provide it.

I am pretty sure on this but I will check this weekend . On my Oliver 1555 , which should be the same as a 1655 , you remove plug D (1/2 pipe plug with allen head ) for the hydraulic fluid out to your remote valve . Once you remove plug D you screw a 3/8 plug (with an allen head ) inside the area from which plug D was removed . This 3/8 allen blocks the area inside and forces hydraulic fluid out the 1/2 hole created by removal of the 1/2 plug D . On my 1555 I plumbed this threaded area (from which you removed plug D ) with a 6 inch long 1/2 pipe and put a hydraulic quick coupler on the end of the pipe . You then plug the inlet line to your remote hydraulic value to this quick connect .

The return for the power beyond from the remote valve back to the tractor is located further back (from plug D) under the seat of the tractor . The plugs for the return are located on the left side (if the driver is seated on the seat ) of the top . If I remember correctly , there are two plugs - a 1/2 plug located on the same level as plug D . This is the plug I used for the return from the remote valve which I plumbed the same as I did the outlet (plug D) to the remote valve . There is also a 3/4 inch plug which I understand can be used for a large return/dump directly into the hydraulic sump but I have never plumbed a power beyond to this port .

I will check on my 1555 this weekend .

First clean off all of the dirt with a air or water hose. Remove 1/2" plug "D". insert a 3/8" internal plug (has an fitting for a allen wrench or a square) into a threaded area that is 2 to 3" into the opening. This port now becomes the flow to the external valve. If you are using a two hose valve, the return flow goes to a plug (not identified in your photo) on the side of the cover. There are two 1/2" plugs, use the forward of the two. The plug that is under the adjustable restrictor is the outlet to a remote. If you have a three hose valve (third hose is a drain hose for rapid lowering) the third hose goes into plug "G". "G" is into the resevoir, if you remove it, get ready for a fluid, as it is below the oil level. System functions as follows, Fluid flow comes from the pump, up into the main housing, is exposed to the main system relief valve, through the filter and across the housing from right to left, turns and flows back to the Flow Divider (the valve that has plugs "E" & "F" in it) The Flow Divider sends 1 1/2 GPM to the steering then to the cooler. After the fluid leaves the Flow Divider, it raises up through a connector into the cover assembly. Flow goes to the left valve, through it then to the right valve, then drops down into the main housing, to the Servo Valve that controls the three point hitch. Plug "B" just plugs a factory drilling that was made for the passage from the filter. Plug "A" just plugs a factory drillng for flow to the flow divider. Plug marked "C" is the filter bypass valve. Should restriction become too great (either by a restrictive filter or high viscosity oil from low temp. ro improper fluid) fluid comes across that passage and goes to the Flow Divider. By inserting the plug, you created a road block for fluid flow and directed it to the external valve and directed it back into the system. Remember, if you disconnect the external valve, you must remove the internal plug, or provide a path for oil flow back into the system.

Here is a picture to compliment Mr. Star's excellent description.

(Yeah, I know. Mine needs cleaning too. ":^) )

OK, when I used my 1950 and power beyond, I took out plug D and inserted or removed a smaller plug on the inside. I reached the plug by using an allen wrench. I then plumbed the opening D to be the pressure side of the power beyond system. I do not remember where i plumbed the return line. This was over 20 years ago, when we used the tractor to powerup a stone separator that took stones out of the potatoes. All the chains were driven by hydraulic motors and that is why I needed the power beyond. Maybe someone else can add to this post.

You don't need it now,but plug F is where you test power steering preasure.
