On My 1650 the left hydralic hose's for the cylinders always has pressure on it. I have to shut tractor down to hook anything up, What could cause this? | ||
| Marty Lappin (M_lappin) |
You probaly have a scratch in the spool in your valve body which lets a little oil leak past it and builds pressure in the hose while running. Our 1855 does the same thing, it has the float valve on it so once the tractor is off moving the lever releases the pressure. | ||
| John Schwiebert |
You are on the right track wrong railroad so to say. Oliver spools for the 50 series are not selective fit per say and the check valve will hold the pressure in the line. What model and brand of couplers are you using? | ||
| Bubba Longwell |
John is right. They should hold pressure. I replaced all of my couplers with Pioneer Quick-Couplers from the AG store; end of problem. They are expensive but I would never go back to standard couplers. | ||
| Marty Lappin (M_lappin) |
What I was getting at on one of our tractors we had a bad spool in it and it would leak enough oil past it that no matter what it would build enough pressure in both hoses, that no matter what it was really difficult to hook or unhook the hoses, and yes, all we use are pioneer couplers. | ||

Now here is a question since we are on hydraulics. On my 1600 it can't hardly be used on anything that requires two remotes. Reason being that for example on my V-rake when raising the rake wheels the wings will try to fold or if you try to fold or unfold the wings then the wheels will try to raise. Obviously some leakage between valves or something going on. | ||
| John Schwiebert |
Are any of these cylinders single acting? Have you checked your couplers? | ||
| M_lappin |
The wheel raise and lower cylinder are single acting, however I don't have a manual for the 1600, but I followed the directions for a 1850 for setting it up to be used with a single and double acting cylinder. All couplers are only a few years old. | ||
| Bubba Longwell |
You don't have the valves set correctly, the 1600 and 1650 are different, you'll need a 1600 Operator's Manual to figure it out. | ||
| John Schwiebert |
Now wait a minute. 1600 & 1650 top covers will interchange up to a certain serial number. O. K Are you using one or two single acting cylinders and with one or two control handles. Did you loosen the half inch bypass screw down by your right foor at leat 10 turns, have you loosened the bypass screws on the side you are using? Lets start with that information. | ||
| Bubba Longwell |
That's the valves I'm talking about, the bypass valves on the side of the unit. The top covers don't contain the bypass valves. They contain the relief valves. There are also restrictors on the side. It's covered in the book. | ||
| John Schwiebert |
There is only one bypass valve. It is down on the right side. 1600, 1800 & 1900 C tractors and all 50 series are that way. Flow controls and the bleeders to use for single acting cylinders are in the top cover. Thermal relief valve are inside in the top cover, Main relief is on the side. Howm many have you done? | ||
| John Schwiebert |
Bubba, I got home early from my meeting and I followed your instructions. I got my official Oliver 1600 Shop Manual out and instructions were just as I remembered them from the past 40 years. I am refering to pages: F1-51 & 52, F1-60, F1-66 and F2 page 30. Please also refer to F1-66 and you will see where the flow restrictors and interloc bleeders are located,and why they need to be there and what they do. What pages are you refering to? | ||
| M_lappin |
Yah loosened the screw on the right hand side 10 turns. Far as the rest goes like I said I only have a manual for the 1850, and am using one single acting cylinder for raising and lowering of rake wheels, and two double acting cylinders for folding the wings. If I remember correctly I seem to remember the book saying that the lower screw had to be turned all the way in for the 3-point to work right, could be wrong on that one though. But if I remember correctly last year I set the left side up for single acting and the right for double acting. | ||

If someone that had a manual for the 1600 could look it up and let me know it would be greatly appreciated. I don't use it very often on the v-rake, usually stays on the round baler all summer, too much stuff to unhook and hook back up. But once in awhile its a lot easier to use it than bring another tractor over. If anybody actually had a 1600 manual they are looking to get rid of I would be interested in it. I believe that when I checked with Wyatt they said they couldn't get one. Really do like to have a owners, service, and parts manual for all of our tractors and other equipment. Makes it sooo nice to look something up, or to look up our own part numbers instead of trying to describe something over the phone to the kid working behind the counter that thinks all tractors have always had computers and cabs on them. Thanks again for any help. | ||

You should run the single acting cylinder on the right remote. I have been using my 2050 on my hay mower, with the double acting cylinder (swing) on the left circuit, and the lift (single acting) on the right. I left the screw down by my right foot alone (in), and opened the interloc bleeder for the right side. Everything works just fine this way. The interlock bleeder screw is the one with the larger slot for your flat screwdriver. For the manuals, have you tried the Floyd County Museum? ( www.olivertractormanuals.org ) They should have what you need. | ||

Thats how I had the 1600 set up for the rake, I know it is because I left the setup alone since last year and have the tailgate on the roundbaler hooked to left side. Had it backwards in the previous post. I should have also mentioned that it only does it if you let a cylinder reach the end of its stroke and you can hear the relief valve doing its thing. | ||

John, It was you who stated "1600 & 1650 top covers will interchange up to a certain serial number". You have just proven yourself wrong. Trust me, I have both tractors and the operator's service, and parts manuals that came with them. I've also worked on them enough to assure you that only the relief valves (4 of them) are in the top cover. The rest are as I stated and I know perfectly well what they do. M_lappin, Hope you take Chris' suggestion and get some manuals. If you really have made a relief valve "do it's thing" then you would know that they are single uses valves... once they blow, that's it, they must be replaced. My AGCO dealer sells a set of 4 for $50. | ||

Bubba. Those are the thermal relief valves not the main relif valve for the sytem. The covers will interchange. I have done it. I also have a genuine Oliver shop manual plus a few parts books. I started working for an Oliver dealer in 1960. Your flow adjustment and bypass adjustment screws are located in the top cover. They were that way when the 1800 was introduced in 1960. However not all of them had all four thermal relief valves. The parts numbers will be different but they will interchange untill the parallel valves. | ||
| M_lappin |
Bubba, I was refering to the main relief valve towards the front of the housing, the one under the 1 1/4? plug. |
