1650 hydraulics

Posted by Patrick Pigg on April 28, 2018, 9:09 pm

Hi Larry, any thoughts on why return hydraulic line is staying under pressure at all times even with engine off?

Re: 1650 hydraulics

The system was designed that way. It has interlocks and the tractor has to be running before any oil can move on your hydraulic cylinder. Larry

550 oil restrictor disc

Posted by Mark Shane on April 22, 2018, 9:30 pm

Hi Larry, Some how I lost the oil restrictor disc while changing the oil and filter on my 550. Would it hurt to run the tractor without it? Where could I find these oil restrictor disc? Thank You.


Re: 550 oil restrictor disc

Posted by Larry Harsin on April 26, 2018, 8:03 am, in reply to "550 oil restrictor disc"

I don't have one. I don't think a restrictor disk was used on the 550. I might have a whole assembly for it. Larry

Flywheel Installation

Posted by Brad Blystone on April 22, 2018, 2:21 am

I have an Oliver 1800a diesel that was recently rebuilt. All the timing marks are lined up, but it doesnít fire. Is it possible that the flywheel was installed 180 degrees off?

Ignition switch on Oliver 1855

Posted by Jerry on April 19, 2018, 12:17 pm

Hello Larry.

Been a couple of years since i checked in and I have a question regarding replacing my 1855 ignition switch.

I bought an exact replacement switch for my 1855 as my original one was falling apart. i moved over one wire at a time to be sure i matched it up correctly. Switch does not work. I consulted with the manual and shop manual but only shows the diagram and not a good detail of it.

Here is the thing you may be able to help me with. I had the positive cable removed from the battery. With the new switch in, I went to put the cable onto the battery and the tractor wants to start.

Pretty sure that the wire for IG and ST were reversed so i reversed them and still wants to start with the switch in the off position when I complete the circuit.

Any clues for you to help me out?

Where did you get your new switch and is your tractor gas or diesel? There are many one size fits all parts out there. They may look the same with the same markings for each terminal but can be different inside. The original switch for Olivers with alternators with a coil type regulator are different than Olivers with an internal regulator. When ever we upgrade Olivers from generators or style one alternators to one with an internal regulator we have to install a diode in the harness. Try to find someone in your area that understands these old systems and is handy with a test light. A couple years ago I tried to buy a new harness for an 1850G that had burnt. I had to make up the harness to get the rite one. Good luck..Arnie

Thank you for the quick response Arnie.

I bought the replacement from Maple Springs Farms. My 1855 is a Diesel. My tractor has an alternator.

As the tractor has been sitting for over 6 months or more, is it possible the bendix could be stuck in the extended position causing it to crank as soon as I touch the cable to the post on the battery?

When the battery went dead, it was trying to crank. Just a thought.

Slowly loosen the starter mounting bolts and you may hear it retract. But I am not certain that is it.

Re: Ignition switch on Oliver 1855

You should have disconnected the negative cable from the battery. It is apparent to me that you have your switch wired incorrectly. There is a wiring diagram in your operator's manual. Larry

Thank you Arnie and Larry.

I figured it out.Had to start over and found a wrong wire on the starter lead. All the wires in the harness were tapped up with black tape and couldn't find color match. My unit had a cab originally so not sure if that had any difference in the diagram but I did get it sorted out and starts like a champ.

Trying to find the fuse for the lights. Diagram shows 2 fuses behind the dash but I'll be darned if I can find them in all the spaghetti. Will keep digging into it as now my lights do not function so I think I burned out a fuse.

Thank you


1850D Hyd.

Posted by arnie on April 13, 2018, 9:27 am

I have 1800 plus pounds at the outlets but he is unable to lift a round bale. Is there a port that I can use to check rock shaft cyl. pressure? What do you think is the problem? Thanks Arnie

Re: 1850D Hyd.

Posted by 90% ret'd on April 15, 2018, 9:48 am, in reply to "1850D Hyd. "

If you are using a gauge in one of the remote outlets, keep the gauge there and when you get your forks under a bale cycle the remote to release pressure to "0" on the gauge then try to raise the load with the three point hitch. When doing that the gauge will show the pressure the pump is putting out to the 3pt. if it is less than 1800 psi. and does not lift the bale I would guess the 3pt. relief valve is leaking or it's elbow on the internal 3pt. lift cylinder is cracked and the hydraulic unit will need to come off to make the repairs. The internal routing of the hyd. fluid allows 3pt. pressure to be checked that way.

1963 1600 LPG fluid change

Posted by Michael Schoenenberger on April 10, 2018, 3:31 pm

I cannot locate my operators manual, so I need to know where the drain plug and check plugs are located for the transmission, and hydraulic drain plug. And also does the pto have a separate gear case? And if it does where is the check and drain plug for it?
Thanks

Re: 1963 1600 LPG fluid change

Posted by Larry Harsin on April 21, 2018, 7:48 am, in reply to "1963 1600 LPG fluid change"

There is a drain plug on the right rear of the main frame. It points toward the back rear of the drawbar. There is also a drain plug on the bottom of the transmission. It is forward of where the drawbar hooks onto the tractor. The PTO gear case is like 770 & 880 and it has it's own separate oil. The check plug for that is a small 1/4" plug that points back. Get another manual from the Floyd County Museum. 641-228-1099. Larry
