Rear hyd

IP: 69.130.186.216 Posted on March 30, 2012 at 10:11:13 PM by Kevin M

My Oliver 1850 when I raise my 15 ft wheel disc, it's a bit slow and when I lower it, it stutters on it's way down. Can you tell me the most likely cause and what to do to fix it. Thanks

You have to turn in the restrictor valve on the line that goes to the base of the cylinder. Your Operator's manual will explain this. If you need an Operator's Manual, you can get one from the Museum in Charles City. 641-228-1099. The Operator's manual will tell you many things about your tractor. Larry

Just checking to make sure we are talking about the same thing. The rear remotes the restrictor is at the base of the cyl? I have a manual coming but it was not sent till fri so I won't get it till mid part of next week and I really need to get in the field on Saturday. Thank you so much for your advice

Yes. The restrictor is at the base of the cylinder. Larry


Rear Rims, Tires / 550

IP: 50.50.76.137 Posted on March 30, 2012 at 08:58:08 PM by HH/Mineral Point

Hello Larry: Can I go up a size or two in rim diameter on my rear tires and, if so, what can I safely go to? 1962 550 gas. Seems like I could get good used rims and very serviceable tires for what I'd spend on just news tires in that small size. Thank you very much.

IP: 75.104.168.210 Posted on March 30, 2012 at 10:19:41 PM by Larry Harsin

Yes. You can. It will change your ground speed to faster. Larry

Re(2): Rear Rims, Tires / 550

IP: 50.50.76.137 Posted on March 31, 2012 at 04:58:52 PM by HH/Mineral Point

I do understand about the ground speed. Should I look for rears off a 660 or 770 to 'bolt right on,' and are there other tractors (incl other mfr, and model)I should look for?

Re(3): Rear Rims, Tires / 550

IP: 75.104.168.210 Posted on April 1, 2012 at 06:42:15 AM by Larry Harsin

I don't think that tires from a 660 or 770 are going to bolt on. I don't think 30" rims and tires are going to work. And, I don't know which "other brands" will work. You'll have to shop around. Larry


880 diesel prime

IP: 173.88.2.254 Posted on March 29, 2012 at 05:42:49 PM by Larry

Larry: we just bought an 880 diesel that has had the original fuel pump removed and replaced with an electric pump.The tractor needs a small shot of ether to start, whether it is a cold start or a warm start. It runs great after started till shut off.It always needs that little shot.What do I need to look for? Thanks

Re(1): 880 diesel prime

IP: 75.104.168.210 Posted on March 30, 2012 at 08:09:42 AM by Larry Harsin

If that electric pump is working correctly, it is probably a weak injection head on the injection pump. Larry

Re(1): Super 77 hydraulics

IP: 75.104.168.210 Posted on March 30, 2012 at 08:07:51 AM by Larry Harsin

The seals on the hydraulic pump are probably bad. Larry

Re(2): Super 77 hydraulics

Does the counter shaft go through the hydraulic pump?

Re(3): Super 77 hydraulics

IP: 75.104.183.145 Posted on April 3, 2012 at 07:52:52 AM by Larry Harsin

No. The PTO shaft goes through the hydraulic pump. Larry


Pull plow vs 3 point hitch plow

IP: 50.33.202.30 Posted on March 28, 2012 at 08:21:48 PM by Bob Abbott

Hello Larry, Which plow is better to plow with for my Oliver 1600 and why is it better? Does one uses less horsepower and or puts less wear and tear on the tractor? Using a 3 bottom plow pull type vs 3 point hitch 3 bottom plow type. Thank you you are a great help with my questions that I have asked in the past. Bob

Re(1): Pull plow vs 3 point hitch plow

IP: 75.104.168.210 Posted on March 30, 2012 at 08:06:41 AM by Larry Harsin

A 1600 could handle a three bottom pull-type plow very nicely without weights as it also would a 3 bottom mounted plow. I would make it a choice by what plow I liked best, whether it be a pull-type or mounted. Larry


oil leak

IP: 70.20.44.93 Posted on March 27, 2012 at 06:51:30 PM by J P

I have a 1954 Super 55 I am trying to keep alive. I currently have discovered an oil leak coming from what I think is an observation plate under the tranny. My question is could this be a rear or front seal, how can I identify which one it is and if the tractor has to be split how big of a job is this? Any help would be appreciated. Thanks

Re(1): oil leak

IP: 75.105.44.216 Posted on March 28, 2012 at 07:05:09 AM by Larry Harsin

In any case, it's going to have to be split. Usually, in this case, it is the transmission coming from the bottom shaft by the PTO clutch drum. All of the seals will have to be replaced. For a first timer, it can be a big job. You should get a Shop Manual before you begin. You can get one from the Museum in Charles City, 641-228-1099. Larry


parts

IP: 72.171.0.144 Posted on March 26, 2012 at 07:46:20 AM by rodney

is there a site i can go to look up parts that i need for a 550. i don't know what to call the part. i believe it is a rod that goes from the clutch pedal to a button that allows the engine to start when you depress the clutch pedal. thanks rodney

Re(1): parts

IP: 75.105.44.216 Posted on March 27, 2012 at 08:11:04 AM by Larry Harsin

That rod is called a safety switch rod. I checked and I don't have one. The part number is: 101881A. You will have to check with AGCO for a new one. Or, you could check with Kent Gordon in Palestine TX and see if he might have a used one. 903-729-8349. Larry


77 hydraulic pressure

IP: 68.0.211.2 Posted on March 26, 2012 at 06:28:00 AM by chris

Hello there I have a very simple Question that I need a proffesional opinion on. I recently aquired a new set of transport harrows and my 77 refuses to pick them up. I have consulted my it manual and discovered that the spec is roughly 1100 psi. My tractor is right there. Has anyone ever increased the output pressure with any success or am i playing with fire? I am an earthmoving equipment mechanic so i am familiar with what may happen if i boost it too much, but is there any room for an increase or should i be shopping for a different cylinder arrangement? Thank you in advance for any help you might offer me.

Re(1): 77 hydraulic pressure

IP: 75.105.44.216 Posted on March 26, 2012 at 07:45:30 AM by Larry Harsin

You can safely go to 1250, but don't exceed 1250!! You are probably going to have to put a larger cylinder on there to do the job. Larry

Re(2): 77 hydraulic pressure

IP: 68.0.211.2 Posted on March 26, 2012 at 11:05:44 AM by Chris Silveira

Thank you for your help. I figured that was roughly the number, factory spec + 10 %. One other thing do you know of any place that i can find a set of curtains for tihs tractor, it is a diesel and needs the bump out for the injector pump. Most of these tractors are missing the sides why is that? I can't help but think that there is a pile of panels some where!!

Re(3): 77 hydraulic pressure

IP: 75.105.44.216 Posted on March 27, 2012 at 07:38:41 AM by Larry Harsin

Th best way to find the side panels for a 77 diesel would probably be to run an ad in the Oliver collector magazines. They aren't reproducing them yet. For the HPOCA magazine, email your ad to: hpocaeditors@gmail.com For Oliver Heritage magazine, email: ads@oliverinformation.com The reason most farmers removed the side panels was that the panels were either in the way or that the tractor was running too warm.

Oliver 880 Oil Specifications

IP: 67.158.226.73 Posted on March 25, 2012 at 10:26:59 AM by Terry Wheeler

What are the lubricant specs for the transmission and rear end of an 880 Oliver?

Re(1): Oliver 880 Oil Specifications

IP: 75.105.44.216 Posted on March 26, 2012 at 07:43:35 AM by Larry Harsin

If the 880 has a Power Booster transmission, I would use a fluid such as International Hy-Tran. AGCO also has an oil for this. It will be a Universal Hydraulic Transmission Fluid. If the tractor does NOT have a Power Booster, use 80-90 Gear oil. Larry


Oliver 550 Hydraulic leak

IP: 99.197.0.57 Posted on March 25, 2012 at 07:20:14 AM by William McMillan

My 550 hydraulic steering gear box has a leak, the oil is coming out at the top of the steering tube at the steering wheel. How can this be corrected?

Re(1): Oliver 550 Hydraulic leak

IP: 75.105.44.216 Posted on March 26, 2012 at 07:41:08 AM by Larry Harsin

You will have to put a new seal on the steering shaft at the bottom of the steering wheel. You will have to call your AGCO dealer for the seal. Larry


1900 Clutch

IP: 108.90.195.39 Posted on March 24, 2012 at 07:20:25 PM by Tom

Have a1900 and put grease in clutch shaft hose, now clutch does not want to disengage when i push in on clutch petal, before it worked fine, what did i do? also I removed pipe plug from housing and got a little bit of water?

Re(1): 1900 Clutch

IP: 75.105.44.216 Posted on March 26, 2012 at 07:39:32 AM by Larry Harsin

I imagine that the clutch facing is stuck to the flywheel. I don't think your grease caused the problem. It was probably caused by sitting and not being used for awhile. I would jack up a rear wheel, put the tractor in road gear and try to break it loose with the clutch disengaged and by rocking the wheel. If this doesn't work, you will probably have to take the clutch apart. Then, you'll know what happened! Larry


1855

IP: 67.142.174.21 Posted on March 23, 2012 at 11:36:08 PM by John

I found a low hr 1855 oliver (4900) with a QA loader, the rear mount locks over a tube the front should also have a bracket to hold a pipe style mount but the front one is missing so the front mount is resting on the axle. The loader has no marking nor can I find a mod or serial number of any kind. Is there a web site of any kind that shows mount brackets by brand so I might be able to id the loader I have?

Re(1): 1855

IP: 75.105.44.216 Posted on March 26, 2012 at 07:35:33 AM by Larry Harsin

I don't know of any website. Could you have a welding shop make you a bracket. Larry


1650

IP: 163.153.134.15 Posted on March 21, 2012 at 12:05:11 PM by robert lapage

Hi Larry. We have a 1650 diesel and the the injector pump fixed. We have put it back on and the tractor and now it smokes real bad. I am guessing I need to turn the pump one way or the other to fix the problem? Any suggestions would be helpful.. Thanks Robert

Re(1): 1650

IP: 75.105.44.161 Posted on March 22, 2012 at 06:17:35 AM by Larry Harsin

If you have it set to specs, as far as the timing is concerned, then I would adjust the fuel setting, using the smoke screw. Turn the smoke screw in a quarter at a time and keep trying it. I'd also call the pump shop about it and see if they agree with what I say. Larry


oil

IP: 68.199.185.187 Posted on March 21, 2012 at 10:38:07 AM by chris

hey larry this may be a stupid question but when filling the trans with oil on my 77 does it go to the rear end to and the plug behind the rear axle whats that for, is it an inspection plug? thanks for all your help chris

Re(1): oil

IP: 75.105.44.161 Posted on March 22, 2012 at 06:14:18 AM by Larry Harsin

Normally the oil goes into the front compartment first, then overflows to the bull gear compartment. The plug on the right side at the back is the level plug. That is where you check to make sure it has enough oil in it. Larry

super 55 (gas)

IP: 99.61.248.203 Posted on March 20, 2012 at 09:07:28 PM by Kevin Haverdink

My dad has a super 55 that the engine was rebuilt a few years ago. It doesn't seem to have as much power as before- but worse than that it seems when the tractor runs for more than 10 minutes it really loses power. When it's running it's best it can't even handle 6th gear on the road. Bearing clearances?, governor? or timing off(even though it runs smoothly)?? Runs about 2000 RPM NO LOAD when cold and closer to 1800 RPM when warm. Any ideas would be appreciated.

Re(1): super 55 (gas)

IP: 75.105.44.161 Posted on March 22, 2012 at 06:07:28 AM by Larry Harsin

It could be a fuel problem or it could be electrical, such as bad points or points out of adjustment. It could also be as simple as the valves being too tight and needing adjustment. Larry


Needs pressure plate

IP: 208.31.142.32 Posted on March 18, 2012 at 06:52:05 PM by Casey

Hi Larry. We're looking at buying an Oliver 1800 that runs great, but needs a new pressure plate. How awful of a job is it to replace the pressure plate on this tractor??? Thanks for your help!

Re(1): Needs pressure plate

IP: 75.105.54.58 Posted on March 20, 2012 at 06:29:20 AM by Larry Harsin

If the 1800 has a hydra power drive, the engine with the hydra power has to be pulled out of the tractor. Then, set the engine on the floor and remove the hydra power from the engine to get at the clutch. If it doesn't have a hydra power, you don't have to remove the engine. Larry


Oliver 1655

IP: 206.8.13.95 Posted on March 17, 2012 at 05:21:47 PM by Gary bullock

Hi Larry, my brother has a 1655 gas,he is having problems with it dying. When he starts it it will run for a few seconds then it dies, if you pull the choke out partway it will run longer, we cleaned the sediment bowl screen and he's had the carb cleaned twice. i recently found out that if I hold the linkage between the carb and governor forward it will idle. What do you think the problem is?

Re(1): Oliver 1655

IP: 75.105.54.58 Posted on March 18, 2012 at 02:08:37 PM by Larry Harsin

The problem could very well be electrical. Also, I would test the vacuum, by removing the plug on the intake manifold. If the vacuum is o.k. check for the proper spark plugs. I prefer a non-resistant spark plug such as Champion N-11YC. Also, check the spark plug wires - I prefer the wires with the copper conductor. Korves Oliver has these. 618-939-6681. Larry

Larry - doing engine job on 1850 diesel, Model - 185-2204 / S/N 151863427. Question about clutch, pulled out a button clutch w/ spacers under pressure plate. Flywheel is not stepped. Local tractor mechanic told me if flywheel not stepped should have regular composite clutch. Is that right? Like to know before I order clutch. Thanks

IP: 75.104.168.101 Posted on March 16, 2012 at 06:32:36 AM by Larry Harsin

If it had the button clutch, that is what I would put back in there. I would use those spacers. Use the flywheel as is. Larry

Super 55 Pinion Plug?

IP: 71.55.36.12 Posted on March 11, 2012 at 12:11:58 PM by Rod

I have a Super 55 gas, made around 1956. On the right side, for about a year now, whenever I stop the tractor after working it for more than a few minutes, I get a good bit of oil running out of the hole for the brake actuating lever. When I finally pulled it apart, I had expected to see a leak around the bearings, but instead appear to have found that the plug has fallen out of the end of the pinion. It appears that the plug keeps the transmission oil from coming out of that shaft. Is that right? The seal around the bearings seems dry. Could this really be my only problem? Also, when I replace the plug, do I just drive it in? I do not see any type of retaining ring.

Re(1): Super 55 Pinion Plug?

IP: 75.107.116.35 Posted on March 11, 2012 at 04:21:47 PM by Larry Harsin

Yes. Get a new plug at and automotive store. Take your old one with you. It is a concave expansion plug that you hit with a hammer to expand it. There is no retaining ring. Larry

I recently aquired an oliver 1800.i believe it to be an a model there is no tag but the chrcker board decals an casting numbers(104622a) lead me to believe this. It has a gas hood but has no fuel tank an runs on lp with a tank mounted on frane rail. Can you tell me if these lp conversions were common and how hard is to convert back. Thank you

Re(1): 1800a

IP: 75.105.51.117 Posted on March 8, 2012 at 07:37:54 AM by Larry Harsin

Not all of them were conversions, but there were conversions done, especially in some parts of the country. To convert it back would be a matter of finding the right parts to replace it. Larry

Oliver 550 blade movement

IP: 97.119.21.30 Posted on March 6, 2012 at 07:02:57 PM by G.A.Wegner

The 550 has a blade on it with two features, one is to to change the angle of the blade. The other is to lower and raise it. It looks like the hoses for the blade angle change come out on the side below the seat of the tractor on the right side. Lately the two features seem to be hanging up until I move the blade change some and it starts working again. I wonder if it is low on fluid and if it is do I put gear oil fluid in where you would add for the transmission or is there another place to add fluid and does it then take hydraulic. I also have a loader on the tractor but that system appears to be separate from the rear operation. Thanks.

Re(1): Oliver 550 blade movement

IP: 75.105.50.53 Posted on March 7, 2012 at 06:55:07 AM by Larry Harsin

The hydraulic system that operates the blade, uses different oil than the transmission. The hydraulic system uses a med-grade hydraulic oil such as SAE 20. There should be a place directly below and to the right of the seat where you add fluid. There is a dip-stick there. You really should get an Operator's Manual for your tractor. You can get one from the museum in Charles City 641-228-1099. Or, there is an icon on our home page for you to click on. Larry

Oliver 60 carb

IP: 173.31.75.217 Posted on March 3, 2012 at 07:11:39 AM by Mac

Hi Larry, I recently bought a 1945 Oliver 60 row crop that is in very good shape overall. However, the choke arm on the carb is broke off. How is the best way to go about fixing this? Can I order parts somewhere for it or will I need to buy an old carb and part it out? I think its a Marvel Schebler TSX 120? Also, there is a crack in the frame up forward toward the front end. Can this be welded safely? Thanks for any help you can give me.
