1855 Hydraulics

IP: 74.32.249.22 Posted on August 31, 2012 at 11:16:19 PM by Austin

Hi we have an 1855 that we are having Hydraulic problems with. We had the local dealer put on a new hydraulic pump and set the priority valve. the tractor has a low pitch squealing noise in the pump. It almost sounds like it is starving the pump for oil. is this supposed to make that sound or is there another problem causing it? Thanks

I would have the local dealer come back out and take care of this. If you continue to use it, you might ruin it. Larry

low pressure to power steering

My 1963 Oliver 1600 has only 500 lbs. pressure to the power steering motor. there is 1500 lbs at the remotes. the priority valve spool is not stuck. I'm not sure where to go next.

I'd order some shims for the relief valve and I'd put on about 3 or 4 shims and try that. Then, see what you get and adjust it accordingly. Larry

Oliver 1250 diesel 4x4 transfer case gasket leak

My Oliver 1250 diesel 4x4 transfer case gasket is leaking fluid. Where can i find a new gasket? And how hard is it to repair. It looks like there are only 4 bolts holding the case but are there internal gears that don't want to be moved?

I would just make a gasket for it. I would even consider using high temperature silicone and eliminating the gasket. Larry

Piston sleeve

IP: 65.167.211.242 Posted on August 29, 2012 at 07:55:32 AM by Mike

I am currently installing piston sleeves in a Super 77 Diesel. I have cleaned the sleeve journals over and over again and when the sleeves are checked for protrusion, it measures .006 to .004 with a depth guage. I was told the tolerance should be .001 to .004. I have used a regular micrometer and get measurements anywhere from .002 to .004. What would you suggest for the next step.

IP: 75.104.160.54 Posted on August 31, 2012 at 07:30:20 AM by Larry Harsin

If they are perfectly clean and you don't have more than .002 variation between them, I would go ahead and install them. Larry

Type of oil to use in a 1850

IP: 96.8.161.108 Posted on August 25, 2012 at 06:39:19 AM by Larry Stahl

I just purchased a Oliver 1850 Diesel (one owner). I need to add/change oil in the Hydraulic unit. My operator's manual said to use SAE 10 Supplemen 1 engine oil or Type "A" Automatic Transmission Fluid. But NAPA does not have Type A, only Type F and Dextron. I need to work the tractor, so please let me know what else there is to use. Thank you.

Oliver walk behind plow

IP: 70.94.244.72 Posted on August 23, 2012 at 07:39:10 PM by Melissa Eisner

I just bought a Oliver walk behind plow for my dad as his 70th birthday gift. He is a huge collector. He currently has Minneapolis- Molines, so this plow I felt would be ideal. I just would like to find more information on it though. It is stamped 404 Oliver. I have tried to look on the internet, but not found any thing. Hopefully you will be able to give me some insight so that I can share it with my dad.

IP: 75.104.160.54 Posted on August 27, 2012 at 07:34:03 AM by Larry Harsin

In "The Book of Oliver" Vol. 2, it says: "The 404-X and 405 series (plow) contain a variety of steel, combination and chilled plows with both wood and steel beams which are particularly adapted for plowing weedy and soggy bottom land. They are also equally well adapted for plowing hard, dry ground, for plowing under small brush and for work in stony and gravelly land when equipped with chilled moldboards. The moldboard is high to give great capacity. There is ample clearance under the beams for turning under weeds and heavy trash without clogging. The rear of the moldboard is curved to pulverize the soil well Frog and standard is on piece--gives great strength and a rigid backing to moldboard and share." The book also has pictures of the plows. Larry

Re(1): 1955 pto

IP: 75.105.32.52 Posted on August 14, 2012 at 07:55:43 AM by Larry Harsin

Apparently, you are losing pressure to keep the clutch engaged. Either the tractor is not able to maintain the pressure after the oil gets warm. Or, the PTO clutch pack is leaking off the oil faster than the tractor can furnish it. I recommend you get a Service Manual from the Museum in Charles City. 641-228-1099. Larry

IP: 99.196.64.57 Posted on August 22, 2012 at 07:18:22 AM by Larry Harsin

That filter is on the suction side of the pump. So, when you open it, you hear the sucking. That's the way they are sometimes. The best thing to do is keep a clean filter and light oil in there. That is one place where you should be particular about the oil you use. Get this oil from AGCO. Larry

770 Alternator Bracket

IP: 72.224.186.240 Posted on August 11, 2012 at 10:41:14 PM by Nick

I've got a 770 that currently has a generator on it and the generator has been acting up and I'm thinking of putting an alternator on it instead. I have the lower bracket and the upper slotted bracket for an alternator that came of a different 770. The problem though is the bracket that holds the generator is bolted on with 5/16 bolts, and the alternator bracket has 1/2 bolts. When they switched to alternators did they just drill two of the holes out larger or what?

Re(1): 770 Alternator Bracket

IP: 75.104.160.54 Posted on August 14, 2012 at 07:51:13 AM by Larry Harsin

No. You'll have to rework your brackets to fit the alternator onto the older engine. I usually try to leave the tractor as it was originally, by repairing the generator. Larry

Installing piston pins

IP: 24.31.182.31 Posted on August 11, 2012 at 08:28:15 PM by Mike

Do piston pins need to be pressed in the rod on an Oliver Super 77 Diesel or can the rod be heated so it expands ?

550 Tack Drive

IP: 70.41.128.75 Posted on August 11, 2012 at 05:31:35 PM by Don K.

Larry I have a bad tack drive gear on my 550 Oliver. The gear and shaft, pn#101709-A, in the adapter assembly that engages the distributor gear is bad. The distributor gear looks good. I am trying to remove the gear and shaft from the adapter assembly without wrecking anything. Looking at the parts book, it looks like the gear and shaft withdraws from the block mounting end of the adapter. Is this correct? Is the gear, 100583-A, pressed onto the other end of the shaft holding it from withdrawing?

Re(1): 550 Tack Drive

Yes. That gear is pressed on and has to be pressed apart. Larry

77 gas governor

IP: 23.29.195.225 Posted on August 9, 2012 at 08:00:56 PM by Gord

Hello Larry. I have recently revived a gas 77 standard, and the rpm is all over the map while using a bush hog style mower. While at full throttle, it wanders from about 12 to 2600rpm. The external linkage seems to move freely, is there something internal that might be rusty or broken? The governor seems to cut in when the engine is pulled down under load. Ideas?

1650 Charging system

IP: 71.161.76.55 Posted on August 9, 2012 at 10:38:03 AM by Ward

I have a diesel 1650 with strong batteries and a new alternator, but the ammeter shows practically 'off the scale' plus charging. Is there an actual voltage regulator somewhere on the machine? I was told the alternator had it built in, but must have a wire loose or crossed or something.

Re(1): 1650 Charging system

IP: 97.73.64.150 Posted on August 9, 2012 at 11:29:47 AM by larry from maryland

They came from the factory with an external regulator, just to the rear of the alternator. After all thease years many have have been replaced with the newer internal regulator altenators. If they get over heated they can go full charge all the time, or they can do that with bad grounds or loose wireing.Allso the guage can be bad or have a bad ground.Some repair places will test your alternator for free and see if its the problem.

Re(2): Oliver 88 Diesel IP: 209.50.28.51 Posted on August 7, 2012 at 09:01:09 PM by B A Star

Since water can not be compressed, when the engine was started the water went in on top of a piston. The engine now has a bent connecting rod, thus the piston is not rising in the cylinder reducing the compression ratio, thus not enough heat to fire the fuel. Run it with the exhause manifold off to see which cylnder has the bent rod, it will be the one with the white smoke coming from the port.

I now have the vickers SP221 remote valve installed with two couplers, but I do not have power down. Is this possible with this valve - then what is my problem. Valve does not have a neutral detent feel either. It came off a savage tractor sitting for years on the ground. Thanks again for your expertise! Roger

Re(1): remote valve on 550

IP: 75.107.96.58 Posted on August 2, 2012 at 07:00:38 AM by Larry Harsin

It does not have a detent. It may be simply that the linkage is not moving the valve far enough so that it is not pressurized on the one side. Especially, if it is a used valve. Other than this, I don't know what to suggest. Larry
