1850 Gas

Posted by arnie on March 31, 2018, 12:15 pm

Have you ever heard the story about an occasional 1850 that runs better on AC plugs than Champions? A long time Oliver mechanic at a dealership not far from here told me that once in awhile he comes across one like that. Even more odd, I have a friend who has two 1850 gas tractors and one doesn't care which plug it gets but the other only likes AC's. They both get the same gas and are identical. Arnie

Myself, I hate Champion plugs and prefer AC's or Autolite's. Autolite 65's seem to work well in my 1650.

Yes, I have experienced this. I have no explanations, just use whatever works. Larry


1967 Oliver 770 "Frozen" Right Brake

Posted by Marcel Montane on March 27, 2018, 2:42 pm

I have a 1967 Oliver 770 with a "Frozen" Right Brake. It has been like that for about 1.5 years. It is my backup tractor and not used often enough. I have taken the cover off the brake housing and tried to "unfreeze/unstick" the brake to no avail. Any assistance greatly appreciated.

Thank you,
Marcel Montane

Take it completely apart and clean it up. After you get everything cleaned and apart, make sure the 3 springs in the actuators are ok. If they re stretched or broken, replace them. Larry


Oliver 1555 Hydraulics

Posted by Dane on March 23, 2018, 7:45 pm

Checked pressure at rear remotes and loader controls and get 0 pressure on gauge. Working on for a friend and was told pump was bad. Test would lead me to that so I was going to pull the pump out. I cannot get the cover off top of housing. Is there a trick I don't know? All bolts are removed but can't separate from lower housing. Seems like a silly question but I can't get to budge. Any suggestions would be welcome. Thanks

It doesn't come out by removing the upper cover. Pressure wash the rear of the tractor, Remove the PTO shaft, and check to see if the PTO shaft splines are good both at the flywheel and midway where it turns the pump. If the shaft and or drive hub "located at flywheel" are worn you will need to pull the engine to replace the drive hub. Good time to check clutch. Don't split tractor. You will need a hoist. If the PTO is still turning the shaft and hub may be OK. Remove all the perimeter bolts and using an overhead hoist lift the complete system off. Turn over and replace pump. Does the power steering still work? May not be a pump. May be settings. Get a book. Replace all the gaskets, filter and fluid with new. Good luck.

Thanks for reply. Clearly a newbie here. I took cover off because 3 point lever didn't move. Found 2 broken pieces. One that attaches to under side of 3 point arms and the one that it attaches to. The arm on the draft control was off because arm had slid out. Everything was jammed up. The plunger on what I believe is the flow control was pulled way far out. Got un jammed and plunger went back in like I believe it should. I found pieces to fix all that from a junk tractor. PTO does engage and turn good. Have no power steering either. Started tractor with that top off and fluid shot out of small hole just behind filter housing on front of case but fluid did not come out of holes I assumed it would. Maybe fluid wont shoot out of the bigger holes on each side of housing, not sure. It was suggested i try that by person I got the parts from. Also took filter housing off but there was no filter in there. Any more suggestions would be greatly appreciated. Could that flow contol plunger being pulled out so far cause it to bypass and not build any pressure?

Another thing you will want to check. Set a five gallon bucket under the differential check plug. Remove the plug to see if the rear end is over full. If you catch excess oil the pump seals are leaking and you still need a new pump. Leaking pump seals will allow hydraulic fluid to collect in the differential. If that has happened you will need to drain out the old oil and replace it with new. Maybe you should have a second bucket at the ready.

Re: Oliver 1555 Hydraulics

Posted by Dane on April 17, 2018, 2:28 pm, in reply to "Re: Oliver 1555 Hydraulics"

Wanted to thank you for the advice and to Larry for taking the time to talk to me over the phone. I got the hydraulics working, although really not sure how. I ran it countless times in shop pulling handles, moving 3 point lever, trying to turn wheel, checking pressure. Never had anything. Pulled outside to pressure wash and remove the housing to get to pump and noticed I had a touch of power steering. Started driving around yard and after a minute or so the 3 point arms lifted and I could lift loader arms. Worked everything up and down several times and all appears ok. Possibly air locked? I did take the pressure hose off the inlet of the loader valve and left in bucket for a week. Can't imagine that did anything but that's all I can think of. Then I pulled out of shop to go use and it died and now it won't stay running. Found the flex ring to be out of the injection pump. Been sitting 10 years so not that surprising. Anyways, just wanted to say thanks again for all the advice.


1550 tach

Posted by Ted on March 20, 2018, 7:57 pm

The tach and hourmeter on my 1550 quit working. I removed the connecting nut at the distributor and exposed the tach cable. I started the tractor and the cable did not rotate nor did the cable drive shaft. I was told there is a small brass gear in the little gearbox on the distributor and it is likely stripped. AGCO says this gear is ~$200. Is there an aftermarket gear available? Can the mechanical tach be replaced by an electronic one? The tractor has an alternator with an external regulator.

Re: 1550 tach

Posted by arnie on March 22, 2018, 6:59 am, in reply to "1550 tach"

You can use an electrical tach. By making an adapter plate it can be mounted in the same hole on the dash. BUT. Get a good one that can stand the vibrations that are present on a tractor and not in a auto. I have done this. Works great. Most aftermarket tachs can be set to operate on 4-6-or 8 cylinder motors and are lite for night use. Arnie

Oliver 1365

Posted by Michael Zapponi on March 19, 2018, 8:43 pm

I'm looking at an Oliver 1365 that's for sale. I'm wondering what might cause it to jump out of 1st gear. All other gears and range selector appear fine. When I go to put in into 1st it pops back before I even start to move. The gear lever pops back too. No nasty noises or anything like that. Just a definite refusal to go into gear. Once in about 6 tries it stayed in gear as I slowly let out the clutch and moved forward. When that happened even backing quickly off the throttle didn't make it pop out. This makes me think the clutch may not be adjusted enough so the lowest gear is sensitive to any engine power. Is this likely or am I looking at a major take apart to repair the gear (if such a part is even available).

BEWARE!!! There may be major problems in the transmission. Larry


1800 C final drive breather

Posted by Frank Ovaitt on March 14, 2018, 7:58 am

Larry, Trying to find the final drive breather for my Oliver 1800C gas tractor. I've got a picture of where it's supposed to be behind the right brake but it's not there. Where else would it be?

Re: 1800 C final drive breather

Posted by Larry Harsin on March 26, 2018, 10:43 am, in reply to "1800 C final drive breather"

I don't think the 1800C has a breather. They were on the 1800A, but it was changed on the 1800C. Larry

440 hydraulics

Posted by Paul Bartlett on March 13, 2018, 10:54 pm

Can you use regular hydraulic/transmission fluid in a 440? The book shows type A transmission fluid which is hard to find. What would you recommend?

Thanks Paul

Re: 440 hydraulics

Posted by arnie on March 14, 2018, 6:50 am, in reply to "440 hydraulics "

The old type A was renamed DEXRON 111/MERCON and upgraded. Easy to find..

1600 gas

Posted by Paul Bartlett on March 13, 2018, 10:43 pm

While researching online about B series 1600 gas they show to have a 248 cu. But no where can I find anyone who list any parts for them. Some places list a 1600 along with a 1650 as having a 265. Was the 248 only used In the B series 1600, and do you know anyone who offers parts? I'm needing a head gasket would any other model head gasket work?

Thanks Paul

Re: 1600 gas

Posted by Larry Harsin on March 27, 2018, 7:26 am, in reply to "1600 gas"

A 1650 head gasket would probably work. Call Maibach Tractor in Creston, OH 800-808-9934 or Korves Oliver near St. Louis 618-939-6681. Larry

Steering on a gas 1550

Posted by Ron on March 11, 2018, 9:52 am

After sitting a year, I finally got a new carb installed and itís purring like a kitten. Now, for a new problem. The inner steering wheel shaft has pushed up about 12Ē and milky fluid is steady flowing out between the inner shaft and the tube. I can push the steering wheel and shaft back down, squirting more fluid out, but there is no resistance. No steering of course. It worked fine when I parked it, but the steering column was in the forward (up) position. Any ideas??

Re: Steering on a gas 1550

Posted by Larry K on March 16, 2018, 8:04 am, in reply to "Steering on a gas 1550"

Sounds like water in the oil. Is it possible that it froze and the expamsion pushed your shaft?

Oliver 1850 Diesel Engine oil

Posted by Ron Hardesty on March 3, 2018, 9:59 am

Larry Hi:
I have owned my 1965 Oliver 1850 Diesel now for 40 years. Whemn I bought it the Oliver dealer told me not use Diesel oil in the Engine. He said to use a high quality gasoline engine oil.

The tractor has the 354 Perkins Diesel engine in it. I have had no problems but was wondering if I should be running an oil designed for diesel engines or continue using the oil I have been. I use the tractor now just for the up keep of my property such as bush hogging.

What is your advice.

Thank you
Ron Hardesty

I would continue using the same oil you had been using. If it worked that long, I would stay with it. Larry
