1855 oliver pto

Posted by Dave Ball on December 17, 2017, 10:13 am

I have an Oliver 1855 that I just use to bale hay . The PTO discs have failed twice in the last two years and are now tore up again ! I suspect that there might be a problem with the control valve unless you have other ideas ? I have not checked the hydraulic pressure ; but everything else works fine . I can not find anyone locally that can tell me how to adjust the control valve . Can you tell me how to adjust it ?

You need to get a Service Manual for your tractor. You can get one from the Floyd Co. Museum in Charles City. 641-228-1099. Larry

1600 hydraulic ports

Posted by Alan Tabor on December 15, 2017, 1:24 pm

Hi Larry, I have a 1600 made in 1963, serial #128735 that has a different hydraulic setup then my 1550. I would like to access the power beyond ports but what appears to be the output port on the front left side of the casting is block by what looks like the relief valve case. The other plugs on the side for the return are different and not sure which one to use. The filter for the system is located on the left side under the seat, not in front like my 1550. I took a picture of it to the nearest AGCO dealer (90 miles round trip) and the mechanic said he wasn't sure. We looked at their IT book and it didn't show a casting like the one on my tractor. He did say he saw no reason why I couldn't just tie the control handle back on the existing remote, as long the attachment had an open center control valve. But I'd rather not do that if I didn't need to.

I didn't see a way to send you the picture on this page but hope you can still help.

Thank you

I have power steering assist on the mentioned tractor, The pump mounts to the front of the engine with a reservoir above for the fluid. What should I be using power steering fluid or a type of hydraulic fluid ? your assistance is greatly appreciated.

I had one like that in my shop last winter and used Dexron. Worked just fine.

2-70 clutch

Posted by David Bedker on December 11, 2017, 11:18 pm

I am in the process of getting the third clutch in my White 2-70 in two years. The first was normal wear, but one of the ears where you bolt the bell housing on was broke off ,so they welded it back on. A year later the clutch was shot again. the mechanic said that the welding broke on the bell housing and things got out of alignment and ruined the clutch.

so he got a different bell housing and replaced the clutch. About a week ago the clutch stopped working again. This time the throw out bearing seized up and wore the fingers off. The work is being done at a former Oliver dealership, but the old oliver mechanics are long gone. What would make a throw out bearing seize up? Is there something they are not doing right?

I have seen ears break off of bell housings or bolts that have drop out but have not seen clutches go bad because of that. Make sure the dowels are in place. The most common reason for throw out bearing failure could be misadjusted. If it is riding on the fingers constantly it can fail. Lack of grease. Some are pre greased. Some are not. Also not greased inside and they hang up on the center tube. Another reason is not being replaced every time the clutch is renewed in the interest of saving $. Those clutches are very basic and should not fail prematurely.

We discussed this on the phone. Hope you got it fixed. Larry

Oliver 1850

Posted by Danny Shafer on December 9, 2017, 6:34 pm

Iím having an issue with our Perkins in the 1850. It constantly will blow blue smoke out the exhaust almost as if itís burning oil, no matter the RPM, good oil pressure. Weíve changed the oil too. Top half of motor was rebuilt quite a ways back (10 years). Has been siting for quite a while now as well. Any help would be appreciated as to what it might want to look out for, thanks.

It could be a bad injector or a broken piston ring. Larry

1755 Hydraulic ports

Posted by James on December 7, 2017, 6:56 am

I am having problem with the out side port on my 1755. I put a loader on the tractor and used the inside ports to raise the loader and the out side to operate the bucket. now the bucket will dump but not raise. if you change the hoses around the bucket will raise and not lower. if you switch ports than the same happens with the loader. I changed out the female end on the port with issues and that didn't help. I checked the spool valve and it was clean. where do I go from hear?

Thanks for any help.

I'm sure I understand your connection layout, but we had an 1850 with a loader do the same thing while loading bales this past summer. The loader went up and down ok but the bucket would not raise but would go down if you did manage to get it to raise. Turned out to be an old hose that had a lining that was flaking a part and pieces had traveled to the connecter and plugged it. This loader is never removed so taking of the connecters and replacing them with pipe unions and a new hose cured the problem. Good luck

I donít think it a hose but I can change them. When I changed the coupler end and the oil drained out a bit the bucket would go both ways for just a bit and them back to one way unless you reversed the hoses and them it will go that direction bit not the other.Could it be something with the pump or calving?

Don't it is the pump if the booms go up and down.

1755 hydraulic problem . I was having problems with the out side ports on the hydraulic while running my loader so I bought a valve and plumbed it in to the lines as I have seen it done on other tractor s but now I have no hydraulic pressure In eather port and the lift arms wonít lift when they have a load on them. Any ideas?

Re: 1755 Hydraulic ports

Posted by James Childress on December 17, 2017, 11:31 am, in reply to "Re: 1755 Hydraulic ports"

I found out today that if the loader is being raised that the lift arms will raise but wonít go down until you push the loader lever up or down is the a priority problem how do I remittances this?

Sorry but I'm not smart enough to answer that. I think I remember Larry saying that there were different systems in use on Olivers in those models. We had a heck of a time getting a batwing mower to work on an 1850D. Good luck.
