1 Set of Remotes, 2 Levers- 1650

1970-1655

Member
I have a late 1650 with 2 levers for remotes but only 1 set of outlets. How do I plumb for the second lever outlets? Is this the same as the power beyond discussion? Can 1 set run two way cylinders and the other set run single hose/ one way cylinders? I bought a mower and need the extra hoses.
 
Is your mower mount on the 3 point? Do you have an operators manual You can not use the 3 point and a single acting cylinder at the same time. More details in the morning. J.
 
3 point mounted. It is a Bush Hog SM-60 ditch/roadside mower. Two way cylinder on the side shift, one way on the deck tilt mechanism. I have the original operator's manual that came with the tractor when it was new. I could change to 2 way cylinder if needed. Just hoping I could use it the way it is set up.

Time to go back and read the manual again.

Thanks
 
The picture is a 1655 with dual remotes. The hydraulic housing should have pipe plugs in it on the opposite side of where your hoses are now. My tractor as well as the one in the picture have 6 inch nipples with an elbow then a hose with the quick coupler. As long as nothings broke internally it should work. Which side are the hoses on?

The hoses are on the left side when looking at the rear as in your picture. If I add the right side do I need to adjust a screw or anything?

We have one grand-daughter tonight so I have not read book again yet.
 
For the right side looks more like a 10 inch long nipple to clear the PTO lever. I'm not sure on adjustment I would screw some hoses in and put some couplers on and try it. You might have to hold the left lever and work the right one back and forth to free it up after spraying some lubricant. J. knows the proper adjustment's I just fumble along!
 
Greg, how long are the hoses from the elbows to the connections. It looks like they loop around the front then under the axle housings. Am I correct? My 1550 had the left side elbows plugged and nothing on the right. I want to get both sides useable. I could never figure out from the parts book how the lines were routed. I set up a single-acting on the right to run my MoCo, left side is plugged.
 
Mike, They are looped around the axle on mine. I have a parts 1650 out in the weeds and they had used pipe nipples, elbows and pipe with the coupler. I just measured the length of hose is around 56 inches. Picture if it helps.

Here it has been over 41 years since I did this, so I may miss some of the finer points, but just remember with a single acting cylinder and you want to lower the cylinder that oil that would normally go to the rod end of the cylinder has to go someplace. In the Oliver you also pilot operated check valves which means that need pressure to knock the ball off the seat so you can not just route the oil to the reservoir. Oliver routes this oil through the bypass valve which disenables the 3 point. When I did this for a living the only application for single acting single cylinders were mounted corn pickers.
 
Thanks for the picture, Greg. Maybe I can help, here. Attached it a schematic of the hydraulic system from I&T. You can run the remotes as single or double acting. For double acting and 3-point the bleed screws and bypass valve have to be closed. Any time you need a single acting the bypass valve has to be opened. This prevents fluid from going to the servo valve (3-point) so you can't use it. If you need one double and one single, the single has to run off the right valve, bleed screw opened three turns. It took me a while to figure this out between the service and operating manuals and actually trying it. I also had the entire system apart and understood how it worked.

Forgot to add that on single acting cylinders the hose should connect to the BASE port. Words BASE and ROD are cast into the housing flange. Here is a cross section of the remote valves.

Thanks for all the discussion and for the scans. Looks like my 3 point will not work if I use the 1 way cylinder so I will look into switching to a 2 way.
 
Did they print OK? Cannot attach pdfs here so I converted them to jpegs. They look fuzzy here. My email's open, send me your address and I'll give you the pdfs. Or anyone else who wants them.
 
Thanks for the schematics and all the replies.
I am going to try attaching a picture of a mower like the one I am working on. Mine also has a tail wheel to support the pivot point that the one in the picture is missing. I have a couple of ideas so I can have it floating and not forced down and twist something. If I try making a link using chain I will probably have to support the cylinder some how. It is the cylinder that tilts the mower head. There is a 2 way that moves the head in or out.
