My Oliver 77 pulling tractor bull gear cracked down near the axle.This let axle chew the bull gear teeth and now how do I get the bull gear out. I pulled the snap ring and loosened the end of the axle but the gear is tight. Any ideas Thank you Ken Smith

You remove the snap ring like you did. Then, you remove the 6 cap screws that hold the cap on the outer end of the axle. Then, take a sledge hammer and hit the axle hub and it should pop right out. Larry


Oliver Super 66 gas

Posted by tracy scott on August 28, 2017, 2:08 pm 165.156.39.18

Hello, I am trying to help a friend out with his tractor. It has sat in the barn for 3 years without running. I have rebuilt the carb for him and today when we installed it and hit the ignition, it tried to fire off and hit a few licks right off. If you choke it, gas will run out of carb throat. We pulled plugs and they are DRY. I am a little confused as to why the fuel is not reaching the cylinders. I ran a wire in every passage and sprayed out the carb with cleaner and compressed air. I really do not think it is the. carb!! I was thinking it could be the intake gasket leaking not sucking the fuel mixture in but when you put your hand over the carb throat and crank it over, it sucks pretty hard. Thoughts?????

What you say is true. I would pull the spark plugs and put a spoon full of oil in each spark plug hole and then try to start it. Maybe you should pull the valve cover and see if they are all working and not stuck open. Larry


Where to get parts for Oliver 1550 Gas Utility Tractor

Larry, the Oliver 1550 Gas Utility tractor, will the 1600 or 1650 model (gasoline) are the parts interchangeable with these models. PTO, ignition, exhaust...

Some of the engine parts will exchange. The ignition has a different distributor. The 1550 Utility and the 1650 have more parts in common than the 1600. Larry


Paint color

Posted by Brian Kessler on August 27, 2017, 8:05 pm 135.26.195.65

Why do all the books say the "supers" were meadow green? All that I have ever seen look darker. My feeling is they went to meadow green with the 3 digits and up.

Re: Paint color

Posted by Larry Harsin on August 31, 2017, 9:38 am, in reply to "Paint color" 172.242.140.109

The Supers were Meadow Green also. Everything from late 1952 on up was Meadow Green. Maybe the ones you saw were faded or something. Larry


carbeurator issues

Posted by Ben St.John on August 27, 2017, 9:24 am 207.228.78.199

Hi there Larry, I am the proud owner of a 1954 Oliver 88 standard. It has some carb issues and I am looking for a reputable source for a rebuild kit. It runs but it doesn't rev up. I believe it floods, and this is why it stalls. As well I need to do the wheel seals, front and rear axles. She's a really neat machine and all works on it, just needs some tlc to get it back to running specs. So to streamline this, I guess I just need to get a good source for new parts to do so. So if you could forward some good part sources, it would be greatly appreciated. Oh as well, is there any where to find a good service manual? I've scoured the net trying to find one and have had minimal success. Thank you for your time, sincerely, Ben St.John.

I would suggest calling O'Brien Co Implement 800-320-6224. They have AGCO parts. You can call Korves Oliver 618-939-6681 near St. Louis. They handle a lot of after-market Oliver parts. Larry

1940 Oliver 70 Throttle Linkage

Posted by Grant Carson   on August 23, 2017, 4:24 pm 24.101.158.1

Larry, I'm restoring my first tractor, a 1940 Oliver 70. The only part I'm missing before I can start it up is the linkage that goes from the throttle lever to the governor, and then from the governor back to the carb. I've called Maibach's in Ohio and searched the internet with no luck. Would you be willing to share any other Oliver yards you know of that might be worth calling? If not, would you happen to have any detailed pictures of the setup that could aid in my search? Thank you very much for the help.

Using a rotary cutter yesterday clipping pasture and PTO made a noise and quit working. disengaged clutch and tried to engage and will not move. you can turn PTO shaft by hand. but can not engage the PTO with tractor running. Hydraulics still work. What could be the problem?

My dad has a 1958 Oliver Super 77 with 8 ft Belly Mower; one of only 32 that were made during construction of the Kansas Turnpike. He busted a belt and has questions about the v belt configuration. He asked if I could help him find an answer. Is there someone he could call, or do you know if there is there someone in south central KS who could help him?

What is the best brand of oliver paint for a 1655? Spray can and quarts. I've been using Tallmans at specialty paint but not sure if it's going to hold up or not.

I use Van Sickle paint with extra hardner. The ultimate would be to use automotive paint, but it is more expensive. Larry

Oliver1755

Posted by Jim Clark on August 13, 2017, 4:37 pm 184.1.215.62

Hello, I just bought a 1755 Oliver from Messicks Farm Equipment in Elizabethtown Pa. This one has two large external cylinders on the rear attached to the upper hydraulic arms of the 3 point hitch. The right cylinder is leaking when you try to lower the arms. I tried lowering the 3 point arms using the 3 point HYD. lever that I have always used on my 1600 or Super 55 but they won't go down. If I try and use one of the remote levers this is when the fluid comes out of the right cylinder. I ask a guy sometime ago what those cylinders were used for and he told me tat it would allow the tractor to pick up heavier loads. I thought that the cylinder that controlled the lifting was located in the top rear end housing just under the seat where the hydraulic filter is located. Either way the 3-point arms will not go up or down. I haven't tried removing the cylinders or tried to by pass them in any way. A Mr Martin in Newville, Pa at Martins Tractor Parts said that I could remove the hose coming from the cylinders and just plug the hole they were going into the housing, where I feel the hydraulic cylinder is located and everything would work again. For some reason I don't buy that idea. I think there is more to it than that. So now here is my question. Can I remove those cylinders without messing up the hydraulics. Is it just that easy to plug the hydraulic connection in my housing and like magic the hydraulics start working as never before or do I have a major problem here that will require a replacement hydraulic pump and both of the cylinders getting rebuilt? I'm sure their is someone out their way smarter than me that can help me figure this out. Any help, Advice, Suggestions, People to ask, or a place to go with in 100 -150 miles of the town of Bedford, Pa 15522, please let me know. It's done farming. It's time to make it look pretty, take ride's on, go to parades, admire and enjoy it's true beauty. But everything needs to unction as it did when it was new. Regards, Hoss

Re: Oliver1755

Posted by Larry Harsin on August 16, 2017, 8:13 am, in reply to "Oliver1755" 172.242.140.109

The hydraulic cylinders that you are having trouble with are the lift cylinders for your category 3 hitch. With a category 3 hitch, the internal cylinder that lifted the category 2 hitch was eliminated. I would disconnect the hose that goes to these cylinders and force them down to get them completely retracted. It could very well be that water has gotten into these cylinders to form rust and make them inoperable. If this should be the case, they may have to be removed from the tractor snd disassembled and clean up to make them operable. Larry

Re: Oliver1755

Posted by Jim Clark   on August 17, 2017, 6:24 pm, in reply to "Re: Oliver1755" 184.1.215.62

Thanks for getting back to me Mr Harsin. So the only way I'm going to have any kind of 3 point hydraulics is to get the Category 3 cylinders to function. I was told by another guy that I could just take the lines of the cylinders and remove them and everything would be as it should. I'm really glad I didn't follow his advice.

Thank you so much, Hoss


Rear Main Seal

Is there a way to completely flush and rinse the hyd system on an 1850 diesel? Steering and all. Thanks

Re: 1850 Hyd

Posted by Larry Harsin on August 16, 2017, 8:04 am, in reply to "1850 Hyd" 172.242.140.109

Not really. You can't get all of the oil completely out without taking it apart. I run the tractor and put out all of the oil that will. Then refill with new fluid and change the filter as well. Larry

Oliver 1850 Draw Bar Height

Posted by Michael Novak   on August 10, 2017, 12:27 pm 75.72.16.11

Hello Larry, My Oliver 1850 has 18.4-38 on 16 inch rim on rear.The problem I am having is Draw bar height. All the machinery I use that has a screw jack must be set down on a 5x6 block of wood or I can't get the pole high enough to unhook the haybine, baler,chopper, etc. Is there a draw bar with more of an offset available, or do I need to change rim / tire size? My 1st Oliver 1850 had 18.4 - 34 rear tires on it and I had none of these problems. Will the rims for the 18.4-34 work on these wheels , or would I need wheels too?? Thank you, Michael

Posted by Larry Harsin on August 12, 2017, 11:07 am, in reply to "Oliver 1850 Draw Bar Height" 172.242.140.109

Oliver 1550 Diesel - big troubles???

Posted by Tom Cooley   on August 4, 2017, 2:31 pm 165.225.38.200

Larry, following up on an earlier question, my 1974 Oliver 1550 was leaking small amounts of oil into the coolant (otherwise ran fine, didn't overheat or anything). I had a tractor shop take it to look further with hopes it was simply a head gasket. Got the message today it needs a head $1800 (cracked in 3 places), cylinder compression is low (around 220 - 280)$1500, needs an intake manifold, injectors bad, and so on. All tolled, $7500 (for my $4000 tractor). Is there a better place to find parts to make this less painful, or where do I sell an otherwise solid tractor to at least cut the losses??? Its been a bad day Tom

55 transmission/clutch

Posted by Carl   on August 3, 2017, 7:52 am 69.84.72.12

In previous conversation I stated I was pulling tree stumps and working the tractor pretty hard to the point the clutch would slip. After three times there was a loud click in the transmission. I jacked the right rear tire and rotated it and it would click and kind of lock in three different spots. On the second rotation it clicked in between the first rotation spots. On the third rotation it was on the same spots as the first and the next rotation was the same as the second etc. The other tire did the same thing. I emptied all three oil plugs and saw no metal. Is it the clutch or is there something else wrong? There was about 5 gallons of oil. Is that the correct amount? Thanks for your help.

Re: 55 transmission/clutch

Posted by Larry Harsin on August 4, 2017, 10:35 am, in reply to "55 transmission/clutch" 172.242.140.109

I don't think it is the clutch. I think it is something else wrong in the drive train. Take the top off and look and see if you can find anything wrong. The 5 gal. of oil is what it should have, so I don't think loss of any oil has damaged anything. Larry


Olver 60 Row Crop engine

Posted by Tim   on August 2, 2017, 9:17 am 75.167.71.91

I am confused about the engine numbers on the 60 Row Crop. I thought the engine is a Waukesha 121. Some places I see the engine for the 60 listed as a Waukesha 160. Is one a series number. The engine serial number on the block is 160120E. Any help you can give me would be appreciated.

That serial number on the tag on the engine is the serial number for the tractor. That is a Waukesha engine. Larry

Yes, I know that the number on the tag is the tractor serial number, but the stamped number on the block is the engine serial number. And I know it is a Waukesha, but is it a 160? When some places call it a 121 are they refering to the cubic inch?

It is the 160 Family engine and I believe the 121 is the cubic inch. Larry


changing steering arm on 1650 wide frt.

Larry is 1550 and 1650 , 1750. the same . steering arm. I was looking at using longer bolts and dropping frt end down and jacking tractor up.or would pulling the radiator and pulling shaft up be better.
