oliver 1850 hydraulics ?

hoosierhog · Mar 30, 2012

Well the rear hyd are a bit slow to lift and stutter when you lower the implement. I have been told i need to adjust the flow control for the hitch. I have a manual in the mail thought it was gonna be here today but its not and the place i ordered it said it was not shipped till today but i need to get in the field this weekend. can some one please tell me where the adjustment screw is and how to adjust it. this is a dumb question as well but where is the hyd fluid fill port and where do you check the hyd fluid level. I know i need a manual. please help
thanks

Correction
Not the hitch adjust but the rear remotes.

If you asked over in the Oliver board you'd get a much quicker answer. The dipstick is on the cap you pull to fill it. I'm not really familiar with the 1850, but it may be between your legs. It'll look like a breather vent with a bolt sticking through it.

To find the restrictor, based on our 1600 I think it'll be under the seat.

Here is a shot of my 1600. The restrictor screw for that side is at the top of the hydraulic housing above the rockshaft for the 3pt. arms. Your 1850 may be in a similar location. The hydraulic filler is closer to the front of that same housing, in front of where the seat would mount. I think the 1850 should atleast be similar. Not that it will be exact. To adjust the restrcition, you're gonna want to turn the screw in, after loosening the nut. Turn it in a little at a time (1/4 turn or so) until it lowers smoothly, then snug up the nut.

The hydraulic check/fill cap is in front of the seat between your legs on top of the casting. Pull the breather cap straight up out and that is your dipstick. Pour hydraulic oil in that hole. If you find the level to be low, that might very well be your problem.

With a Oliver depending on the load on the hyd cylinder you need to have engine runing at a higher rpm to make the valves open properly. That may take away the chatter. Hyd oil needs to be the newer stuff. Personally I use CaseIH.
I think you were asking about the cab awhile ago. I'm sure yours is All Season made in Sherburn MN mine looks the same

Check your oil level, but I doubt thats the problem. One port of each remote has a restrictor so that when you release pressure, the implement lowers at a speed that you select. The restrictor valve adjustment is below the seat, one on each side of the hydraulic unit. It is difficult for me to describe but on each side of the unit there will be two adjustment screws, two will be mirror opposite from each other, these are interlocks, and are for using a single action cylinder. The other two, behind the interlock on the right hand side, and in front of the interlock on the left side are your restrictors. Older 50 series had a locknut on the screws, newer ones had hex cap for a lock, that you have to remove to turn the screw. Turn it in to increase the restriction. This assumes the hoses are hooked up so that pulling the hydraulic lever back lifts the unit. This should solve your lowering problems. The lifting problem sounds like low oil, air which should work out after a cycle or two, or a weak pump. Those are simple hydraulic units, and are easy to work on, one of the things that make an 1850 such a good tractor.

I see you posted on Larrys site too. His answer was REAL confusing. I didn't even understand it.
If you're plugged in to the left side,so you're using the left (inside) lever,look under the rear of the seat on the left side. There are two adjusting screws that take a flat head screwdriver. Both have a locknut that takes a 9/16 wrench. One sets back in a ways and screws straight in to the casting. The other sits out some and screws in to what looks like another big hex nut,an inch or so. That's the one you need to adjust the way JoshPa said.

Make sure that your engine is at least a high idle when you operate your levers. Half throttle would be better. I farmed with one for years, the hydraulics will not cycle properly at an idle.
