1750 steering

IP: 164.144.252.27 Posted on May 28, 2014 at 04:00:26 PM by Matt Vieselmeyer

While using my 1750 diesel today the steering went completely to the left. I can try to fight it back to center but once I release the wheel it goes immediately back to extreme left. This is both the steering wheel and wheels.

The trouble is probably in the hydra-motor. It could be as simple as a broken snap-ring which you could replace. There are no parts available anymore. So, if it is more than a broken snap ring, you may have to replace the hydra-motor. I would take it in to an AGCO dealer and have them "trouble shoot it". Larry


Battery Dying

IP: 66.203.38.3 Posted on May 27, 2014 at 06:32:49 AM by chris

I have a 1963 Oliver 770. When I start my tractor I have an "Amp" light on the dash. I can run the tractor for about 10 minutes and then it dies because the battery is not charging. What steps should I take to troubleshoot this problem?

I would take the generator and alternator to a service shop and have them checked out. Larry


3PT Lift Arms

Oliver 1555 were there lower 3Pt lift arms made for this tractor with Cat I width dimension of 26.00(inches). If so what would the Part/Numbers have been for left and right? All my implements are Cat I

Not that I know of. You'll have to remove the sway blocks to narrow it up that way. Larry


Oliver Clutch

IP: 65.182.246.38 Posted on May 25, 2014 at 10:33:07 PM by Ken

When my 1956 Oliver gave out, I bought a "newer" Oliver 50 HP Diesel (1960's?) that has run great for 10 years. This weekend I was out in the deep woods in Oregon when the clutch gave out. It is stuck in second gear so I cannot start the tractor. When I press down the clutch feels like it engages but I cannot move the gear shift. It is so deep in the heavily wooded area that I cannot tow it out. I need to start it somehow and drive it out. I am not a mechanic by any means. Is there any way to start this so I can drive it out and get it to a mechanic? The numbers on the plate are so worn that I cannot read all of them but I can read 74 612 87. Any ideas or suggestions would be greatly appreciated. Thank you, Ken

You are going to have to figure out a way to hot-wire it to get it started so you can drive it out of there. Larry


1855 Hydraulic pump replacement options

IP: 50.187.18.91 Posted on May 25, 2014 at 06:00:30 PM by Dan

I am in need of a new pump for my 1855. It has the PVB-15 early pump. Seems to be a low pressure problem with the pump. Where should I get a replacement? Due to cost, I want to take the best route.

Contact either your AGCO Dealer or Pump Recom Inc in Independeace MO. 816-252-0791. I would check out AGCO first, and have a service man who knows what he is doing, do it. Larry

My hdro-power works untill it warm up good.Does it need to be rebuilt or just seals put in it.Do they make a kit for a 16oo gas. thank you Steve

Re(1): 1600 hydro power

IP: 172.242.134.43 Posted on May 22, 2014 at 06:55:38 AM by Larry Harsin

Yes. Parts are still available. It might be wear on the oil collector ring and the hub of the direct drive clutch. The unit will have to be torn down and inspected for worn parts that have to be replaced. Yo can get them from the AGCO Dealer. Or you can call Tom at O'Brien Co. Impl. 800-320-6224. Larry

Power Steering Cylinder Endcap

IP: 68.70.134.87 Posted on May 18, 2014 at 12:13:21 PM by 1755D

I have my steering cylinder off my Oliver 1755, and need to take off the cap on the end. I cannot seem to get this done. About all I can think of doing is using the inside cylinder as a ram to get the cap off and that does not seem like the right thing to do. Any help is appreciated.

Re(1): Power Steering Cylinder Endcap

IP: 172.242.134.43 Posted on May 20, 2014 at 07:11:03 AM by Larry Harsin

Remove the sector. Then, you can do what you are thinking, using the inside cylinder as a ram. Larry


Super 88 Hydraulics

IP: 207.177.30.39 Posted on May 17, 2014 at 07:30:29 PM by Zach

I had a cracked center plate and a valve bleeding by on the hydraulic unit of a super 88. I got what I thought was a good deal on a complete hydraulic unit. I changed out the entire unit and now I am having some interesting issues. When I first start the tractor one set of hydraulic lines built pressure until the relief valve blows off. There was pressure on both sides of the valve without actuating the valve. I thought there was a problem with that valve so I swapped it with the valve out of my original unit. Now with original valve I got pressure right away on one line and then back to the same thing as before. Do you have any ideas as to what is going on? Both valves don't do anything, I am just blowing by the relief right away when the tractor starts. Thanks for the help.

Re(1): Super 88 Hydraulics

IP: 172.242.134.43 Posted on May 20, 2014 at 07:08:45 AM by Larry Harsin

It may have a plug in the front passage for power beyond. On the left side, the very front port, could have a 3/8 plug inside the passage, It's about 3 inches in there. You'll have to remove the plug that blocks that passage. Larry

You're right! Thank you very much. Pulled that plug out and everything is now working. I would have never found it on my own. Thanks again.


power booster

I just finished a 770 restoration.I put in a new Sprague clutch. The power booster will not go into low range. I am sure it is not reversed. Is the problem in the overcenter clutch.I would appreciate your help. THANKS

Re(1): power booster

It sounds like your over-center clutch isn't releasing. Larry


fuel/sensor

IP: 76.2.93.122 Posted on May 15, 2014 at 09:49:40 AM by Ben Steiger

Hello Larry, I was bushogging last night and I began to notice the rpm decreasing on my buddys 70s oliver as I went up hill and increasing as I went down. A while later the tractor died. I checked to see if fuel was making it to the injectors, it was. I checked the oil (not knowing if older tractors had a sensor or something) the oil was barely on the dip stick. I topped it off and turned it over but still nothing. There is no smoke or no reaction at all when I turn it over. Any ideas?

Re(1): fuel/sensor

IP: 172.242.134.43 Posted on May 16, 2014 at 06:56:52 AM by Larry Harsin

I'd check the fuel filters and make sure they aren't getting plugged. It sounds like the fuel isn't getting to the injection pump. I'd check the fuel and the filters. Larry


1655 steering

IP: 69.215.48.147 Posted on May 14, 2014 at 02:55:59 PM by Roger Schafer

I have a 1973 1655 Diesel. The front wheels will wobble when going on the road at much above 7-8 MPH. Also when the tractor is shut off the steering wheel has about 1/4 turn free play in it.I also have a White 2-70 and there is no free play in the steering when the engine is off. Does the steering control unit need to be replaced? Thanks

Re(1): 1655 steering

IP: 172.242.134.43 Posted on May 15, 2014 at 07:09:48 AM by Larry Harsin

Possibly but, you should make sure that the pitman shaft is not loose where it fits up into the power steering unit on the wide front. Jack the front of the tractor up and make sure there is nothing loose up there. Larry


Cylinder Head

IP: 173.26.196.162 Posted on May 13, 2014 at 02:25:34 PM by Rick Engley

Great Website. Maybe an Oliver man is the place to find a conncection. :) I have inherited a white 2-63 backhoe that sat for 5 years. The head has few cracks that I have sort of learned are normal. But I have visited a dozen machine shops who say they don't touch anything that old. Dang things have changed. Not even pressure testing it. So I figured I would just go get another one. Well this old tractor I am learning has just about everything available but a cylinder head. Do you have any parts tractors with a good cylinder head? My casting # on the cylinder head is 186402K. From some research I been told my motor is a waukesha 232 diesel and the numbers correspond to a 1555 Oliver. Any information on any heads you might have or where I might look? Re(1): Cylinder Head

IP: 172.242.134.43 Posted on May 14, 2014 at 06:55:42 AM by Larry Harsin

I don't have this part. It is a 232 diesel and the numbers correspond to a 1555 Oliver. Check with Larry Svelak at Austin TX 512-633-5014. Larry

There is a business in Nevada, Ia. That specializes in repairing cracked heads and blocks. You should be able to find them on the internet. Google lock.

I think Larry Kruse is referring to Williams Cylinder Head of Nevada Iowa. Arnold's Motor Supply bought them and I think now it is called Central Iowa Cylinder Head. Larry


Wiring Diagram

IP: 72.231.186.250 Posted on May 12, 2014 at 09:31:55 PM by David R. Kettlewood Sr

I took the old wires off my 1951 Oliver because of excessive wear. I did not record the connections properly. I need to know where the two connections on the voltage regulator go. The third connection I know is the field connection. This is a 6 volt system. I have the connections between the coil and distributor. I do not have the key switch, the amp meter and the starter button to connections.

IP: 67.206.97.167 Posted on May 13, 2014 at 05:58:57 PM by Jack

I have done that to an 1850 a 77 is going to be a very tight fit in the tub. The tranny and rear end will handle it if u keep weight below 5500 so it can spin.


Super 88 head

Larry I need to redo my head on a super 88. will the head off a 1650 fit and does it raise the compression, or how does the 1650 get more compression? I was told to run the intakes and exhust manifolds and carb from a 1650? thanks CS

Re(1): Super 88 head

IP: 172.242.134.43 Posted on May 14, 2014 at 06:48:45 AM by Larry Harsin

No. The head from a 1650 will not fit an 88. The manifolds do interchange however. Larry

Will the motor out of a 550 gas fit in my 66. Are the heads interchangeable from a 550 to a 66

Re(1): Oliver 66

IP: 172.242.134.43 Posted on May 14, 2014 at 06:47:35 AM by Larry Harsin

Yes. The engine out of a 550 will fit in a 66. Most of the heads are interchangeable also. Larry


Positive Ground

IP: 71.55.72.250 Posted on May 11, 2014 at 04:50:57 PM by Kent Gardner

Mr Harsin,what are the advantages to positive ground. I know it was used on a lot of Oliver equiptment. Can it be changed to negative ground ? Is it a lot of work? Thank you KG

Re(1): Positive Ground

IP: 172.242.134.43 Posted on May 14, 2014 at 06:45:49 AM by Larry Harsin

I don't know the advantages to positive ground. I just try to keep them the way they were built in the first place. It avoids confusion. As far as the Olivers are concerned, everything that has a generator is positive ground and everything that has an alternator is negative ground. Larry


1850 Oliver Steering

IP: 108.212.173.255 Posted on May 9, 2014 at 03:38:25 PM by Jim

On my 1850 Oliver 2 wheel drive the steering wheel will go around several times thru the field, sometimes left , sometimes right. If you hit a ditch at a little bit of a angle it will spin the wheel. I replaced the big steering cylinder up front. What can I do to repair this problem. I live in Trenton, MO and would also take to a shop for repair.

Re(1): 1850 Oliver Steering

IP: 172.242.134.43 Posted on May 10, 2014 at 07:16:35 AM by Larry Harsin

The first thing I would do is make sure the blocking valve is not in the down position. The blocking valve is located just in front of the steering column. There is a little hole there so you can get a screwdriver in there. This is covered in your Operator's Manual. Larry


550 Oliver

IP: 99.125.116.80 Posted on May 5, 2014 at 04:42:05 PM by Cindy Ellis

We just purchased an old 550 Oliver & are wondering if there is a way to add power steering. Also the hydraulics seem to be losing power - was wondering if you had any suggestions on either matter. We don't know the year but the gentleman that we bought it from had it for 33 years - can we tell the year from the serial number? Thanks so much for any help you can offer. Our Specification number is 45-0074 and our Serial number is 80 389-519 - any help on how to figure out the year? Thanks much.

IP: 172.242.134.43 Posted on May 6, 2014 at 07:33:47 AM by Larry Harsin

We have a book that lists the makes and serial numbers. Your 550 was built in 1959. Larry

I have a 1550 and can't get the steering box or cylinder to come apart. Got it out from under the tractor but can't get the shaft out of the cast that bolts to the main frame. Is there a snap ring in there?

Re(1): Power stering trouble

IP: 172.242.134.43 Posted on May 7, 2014 at 08:27:09 AM by Larry Harsin

You have to take the lid off of the top and there is a puller bolt that holds the shaft in the sector. Loosen the bolt and it will start to get tight again. Keep unscrewing the bolt and it will pop the sector and shaft apart. Larry

I am completely restoring an Oliver 1465. I have had some trouble finding parts but mostly they have been available with a little searching. I am having trouble locating a transmission clutch release bearing, rear main bearing cap seals and air filters. Any suggestion on where I might look for these parts? I have tried my usual sources with no luck. I have good quality pictures available of each part if you are interested. Any suggestion at all would be appreciated. Thanks!

1755 Hydraulics

IP: 74.75.180.65 Posted on May 1, 2014 at 10:23:31 AM by Ken

Hi Larry Thanks for all you do for us Oliver owners!! I have a 1755 that works great, after pulling a disk harrow or any implement at higher than 1200 rpm, all hydraulics stop working, and a loud screeching sound can be heard, in order to fix the problem, the rpms must be lowered to 800-900 then they are fine for maybe 15- 20 minutes. I have changed oil, filter and suction side hoses, but still have the problem. I'm thinking pressure relief valve is next?? Where is it located?? Thank You.

Re(1): 1755 Hydraulics

IP: 172.242.134.43 Posted on May 7, 2014 at 08:21:15 AM by Larry Harsin

The main pressure relief valve is located below the pump. It is the one closest to the tire. Larry
