Oliver 1800 C model timing

IP: 70.195.66.213 Posted on January 28, 2016 at 03:37:39 PM by Eric Lambdin

I am trying to time our Oliver 1800 C gas tractor. I have found the top dead center TDC line, and the manual says to set my timing light on the 24 degree mark. Is there an additional mark? Or am I supposed to set the timing light on the TDC line? Also, which cylinder is the number 1 cylinder?

104028ASA 1 Flywheel With Ring Gear (7K-1005) And Bushing (106211-A) (Does Not Include 106216-A Timing Mark Tape) (S/N 90525 -) From the AGCO parts listings. I'm guessing the 106216-A tape is missing, was similar to a decal. It had a mark to line up with the TDC and the degrees were on the tape it self. If someone has a "C" with the tape still on they could measure and give an approx. inches from the TDC mark.

Set the thing around top dead center with the engine idling slowly and a timing light. Then when you speed up the idle, the distributor should advance 20¼ at full throttle. Sorry for the slowness in answering, we have been gone for 3 weeks. Larry

Have an Oliver 1265 that I am having trouble with the power steering.Works fine turning to the left but turns hard when turning back to the right.Could this be the relief valve or is there another thing that could be causing this?

880 oliver gas - Carb leaking fuel

IP: 24.72.194.4 Posted on January 26, 2016 at 07:36:36 PM by Craig

Larry, unable to start 880 gas oliver. Carb was leaking fuel, tried two carb kits and installed rebuilt carb, but no luck. Carb leaks fuel from bottom main plug and jet. Assumed float problems but new carb should have fixed. thanks

I would just shut the gas off at the fuel strainer when I not using the tractor. Today's gas just doesn't act the same on these old tractors. Larry

When I open fuel switch at strainer and try to start engine, which will not start,is when carb starts leaking fuel. Found no spark at spark plug. Any suggestions where to go from here ? Thank you ...

You have to have spark!!!! You need to determine why it isn't getting spark. Larry


Hydra Power

IP: 66.230.245.170 Posted on January 25, 2016 at 04:46:11 PM by Arnie

Is it normal for a Hydra Power to "free wheel" in low range? The tractor is an 1850 gas.

Re(1): Hydra Power

IP: 69.26.10.96 Posted on January 25, 2016 at 09:16:53 PM by Bill

Yes, it is normal. It spooked me when I first discovered it on my 1650, but it is normal. I just had mine rebuilt and the guy explained to me how it works. It's a pretty cool idea.

Re(2): Hydra Power

IP: 184.21.143.147 Posted on January 27, 2016 at 08:51:34 AM by Larry Harsin

It helps if you shut off the gas each time you are finished with the tractor. The gas they sell these days just doesn't work as well in these old tractors. Another thing that would help a lot is to put a cup of diesel fuel in every tankful of gas.. Larry


1955 Oliver super 77 diesel

IP: 162.211.184.6 Posted on January 22, 2016 at 07:50:50 PM by Daniel Ryan

I have a 1955 Super 77 diesel that we recently have done a load of work to. Engine was somewhat overhauled with new rings and honed sleeves 3 1/2 std bores. Head was rebuilt and injectors along with injection pump which has a new plunger now. Nice clean fuel system, Engine will start and run rough spitting fuel through at least 3 exhaust ports and will not light up if cold weather (25 degrees) Did a compression test today and average 250 to 275 per cylinder. According to the shop manual is this too low? Or should this baby run ok with those readings? Been working on these diesels for 20 years but I surely do not know everything. Thoughts on where to get a good piston and sleeve set 3 and 5/8 bore or should I stick with 3 1/2 ? Daniel

IP: 184.21.143.147 Posted on January 24, 2016 at 00:24:54 AM by Larry Harsin

I would recommend that you go with a 3 5/8" bore . You can get them from Korves. 618-939-6681 Larry

Thank you larry, but is there a way to have the model number and serial number looked up to get the year and more information about the tractor, or will the museum be able to help?

Re(3): oliver 1550

IP: 184.21.143.147 Posted on January 27, 2016 at 09:11:38 AM by Larry Harsin

The Museum is a great source of information about your tractor! Beginning with the 50 series tractors, they have what they call "Build Cards" on every tractor. The "Build Card" is one of the old computer cards that they punched the square holes in. When these tractors were built, a computer rolled down the assembly line with them. When something was put into the tractor, it was punched into the computer. The Museum found these cards a few years ago, in the paperwork that Oliver had presented to the local Historical Society. The people at the museum have bee working on these "Build Cards" and have figured out a lot of the "codes" to read them, but not all of them. If you call the Floyd County Museum, 641-228-1099, and give them your tractor's serial number, they can tell you many things about your tractor, even who was the first dealership to sell it. For a fee, they will send you a copy of your card. Another thing that every tractor owner should have, is an Operator's Manual for that tractor. The Operator's Manual has lots of info about your tractor and how to care for it and repair some things. You can get these Operator's Manuals from the Museum also. They have Operator's manuals, Parts Manuals and Shop (repair) Manuals for each tractor. Of course, there is a fee for these manuals. Some of the Shop Manuals seem high, but some of them cover more than one model of tractor. Sandra Harsin

Timing 880 diesel

IP: 67.7.210.113 Posted on January 19, 2016 at 12:43:00 PM by Dale

We have a 880 diesel in our shop. And we have tried to time the injector pump. We have followed the book, But when we time it it smokes even after adjust it in the slots. But we have noticed the when we take the side cover off the pump and that is very close where it needs to be, The timing marks thru the pipe plug on top of the timing gears is not even close. Is the pump out of time in it self? Thanks for any light you can shed on this for us! Dale @ Hongisto Implement. 218-879-3397

If you followed the procedure in the book, it should be right. I will give you a call and we can talk about this some more. Larry

1850

IP: 166.181.81.228 Posted on January 14, 2016 at 05:35:21 PM by Kent

My steering doesn't work very well it will turn one way just fine and the other hard or will be fine and then you can't hardly turn it either direction I have lost all control and it put me in the ditch going down the road. It bypasses pretty fast to you have to keep turning the wheel to keep straight any idea if that would be the steering wheel pump or the one under the radiator.

Re(1): 1850

IP: 184.21.143.147 Posted on January 19, 2016 at 07:49:19 AM by Larry Harsin

When you have that condition, it is usually the unit under the steering wheel. Larry


66 Serial number

IP: 24.145.95.204 Posted on January 10, 2016 at 02:02:45 PM by David L jones

I am trying to figure out the year of a 66 that I just purchased but I cant match the serial number with anything 20856-606 the spec is 18-0023

Re(1): 66 Serial number

IP: 172.4.207.196 Posted on January 10, 2016 at 03:48:14 PM by Harry D. According to chart I found, S/N's on 66 started in 1949 at 420001, 1950's started at 421589, The last three digits, -606, is the transmission code. Could you have missed the first number?

Re(2): 66 Serial number

IP: 184.21.143.147 Posted on January 12, 2016 at 08:23:45 AM by Larry Harsin

The serial number you give, 20 856, is listed as a 1955 Oliver Super 66. If, as Harry D. suggests, you have missed the first number, that is a 4, it could be a 1949 Oliver 66. Larry

You need to buy a 100574A Elbow for that heater. Then, it uses the same element that you have. Ag Parts First has them 866-264-9720. Larry

1650 steering

IP: 70.194.69.15 Posted on January 9, 2016 at 03:11:43 PM by Doug

Hi Larry. I was using the 1650 when I heard a soft pop noise and then the steering stopped. The steering wheel turns easily from lock to lock, but doesn't turn the wheels. I can turn the front wheels by hand easily as well, of course once the weight is off of them. Is the problem in the steering motor that's under the radiator? I have a loader on this tractor too. I don't know if that makes a difference to you or not but I am careful with it because of the 1650 lighter front axle. I realize it could be a number of things, but thank you in advance.

Re(1): 1650 steering

IP: 184.21.143.147 Posted on January 11, 2016 at 08:54:11 AM by Larry Harsin

Make sure that the Pitman shaft, below the steering unit on the radiator, is tight to the pitman arm. You may have a problem at this point. Larry


770 Choke/Carburetor

IP: 50.191.61.159 Posted on January 8, 2016 at 11:06:14 PM by Mike Renner

Larry I have a 1965 Oliver 770 gas that always needs the choke pulled out a bit to make it run right. When I pull the throttle down and the choke is all the way in it hesitates even after it is warmed up. Do you think the carburetor has dirt in it or needs a rebuild? Thank you for your time and help. Mike Renner

Re(1): 770 Choke/Carburetor

IP: 184.21.143.147 Posted on January 11, 2016 at 08:51:45 AM by Larry Harsin

Not necessarily. I would try to adjust the load needle by turning it out half to 3/4 turn and see if that helps. Make sure that you are getting good fuel flow to the carb. Larry

Diesel fuel coming out of exhust manifold

IP: 68.188.212.249 Posted on January 4, 2016 at 09:17:25 AM by Leonard

Bartered a tractor for new bathroom. Tractor had not run for years. Had mechanic get it running. Now when we start it diesel fuel comes out of exhust manifold. Changed oil and don't want to run it til I can get it working correctly. Rings stuck, injectors faulty,etc. I'm a mechanical contractor but this is not a boiler or furnace so my knowledge is on low side. Help!

Re(1): Diesel fuel coming out of exhust manifold

IP: 184.21.143.147 Posted on January 5, 2016 at 08:29:38 AM by Larry Harsin

This is a problem we call "wet-stacking". Most of the time it will clear up if the engine is put to work for a long enough period to get the engine warmed up thoroughly. If it doesn't clear up, then you can consider the things you mention. These engines are made to work, not just setting around. They need to be used occasionally. Larry


clutch

IP: 74.214.148.2 Posted on January 4, 2016 at 00:44:46 AM by Dale D

I have a 1952 oliver 88 gas engine tractor, how do I replace the clutch, also tractor runs for a min than dies how do I fix that

Re(1): clutch

IP: 184.21.143.147 Posted on January 4, 2016 at 08:21:18 AM by Larry Harsin

To replace the clutch an 88, remove the fuel tank, unbolt the dash from the frame and fold it up over the engine. Remove the long PTO drive shaft that goes up to the engine. If your tractor has a belt pulley, remove the pulley drive from the transmission frame. Then you will be able to have access to the clutch. If you have anymore questions, call me 712-362-2966.

hydraulics 770

IP: 66.211.233.144 Posted on January 3, 2016 at 02:06:03 PM by Ray Gourley

I have a late model 770 with a loader .When I purchased the tractor the loader was plumbed into the factory ports and controlled with the levers under the steering wheel. several years ago with your help, I added a remote valve and plumbed into the power beyond port. Everything worked well for a while then I started getting oil overflowing the fill cap when I would lower the high lift or when I would shut off the engine. I decided to inspect the pump, all parts seemed good except the ends of the gears had some wear. All tolerances were good and surfaces were smooth. I put everything back together and now the loader will lift normal for about half way up then slows and barely lifts at all. I decided to check pressures and drain system and look at the pressure relief valve. I have 1100 psi, But when I went to drain system through one of the remote couplers it seemed to take a long time to drain and the oil was coming out in spurts and very foamy. before disassembly of the pump everything worked just oil over flowed. Any suggestions would be greatly appreciated Ray

IP: 184.21.143.147 Posted on January 4, 2016 at 08:16:45 AM by Larry Harsin

It sounds like you don't have enough oil reservoir capacity for what you want to use your pump. I have an extra oil reservoir that I can send to you. It will attach to the hydraulic pump on the left side. Give me a call 712-362-2966. Larry
