Oliver 550 clutch

IP: 207.174.231.188 Posted on November 27, 2014 at 10:48:36 PM by john blankenship

I am researching the net trying to find a solution to my 550 clutch problem. My 1969 550 ran fine one day, then worked it hard and broke the steering gear/shaft. Managed to load tractor on trailer, but got home with no clutch. Broke it good, no steering, no clutch. Got the steering fixed with lots of $. Now for the clutch. took it apart, no problems visible. I had the clutch rebuilt four years ago. I took it back to them to see if anything was wrong. It checked out fine on the bench, no problems, right clearances, looks fine. So I put in back together. Ran fine for a couple months, bushhoged the pasture. Went back to the barn, stopped and had no clutch. Again, no indication, no slip. So this morning I split it again, again no visible problems. Tightened all the bolts I could find internal, of which some were loose. The pilot bearing looked good, spun freely. Hopeful that the mere exercise would solve my problem. Wrong. No clutch. Pushing down on the clutch will not dis-engage engine from tractor transmission. I adjusted the clutch with no change what so ever. No clutch. I bumped the tractor hard as I could both forward and backward, no avail. I have started "in gear" to move around, and tried to use brakes to jar loose to no avail. Any help would be nice. Thank you. John

I don't know what to tell you on that. Larry

You have an interesting problem. Is it possible that the clutch disk is warped? While you were bushhogging, was the plate cover below the clutch missing? This might allow clipping to be pulled into the system. I would definitely like to learn what you find as the problem in case it happens to me.

So the tractor will pull just not disengage seems like some problem in the throwout bearing or fork assembley maybe the keyway on the fork for the throwout bearing. Possibly a spring broke in the clutch disc that isn't showing itself unless it is under pressure. Let us know if you get it figured out.

I have an old Oliver track layer. How can I identify the model and year? It has a 6 cylinder Hercules gas engine with a fuel tank behind the seat. Thank you

354 Perkins Block Heater

IP: 64.8.141.71 Posted on November 26, 2014 at 02:54:35 PM by JL White

I have a White 2-85 with the NA 354 in it. I want to add a block heater to it, and would like to add it to the 3/4 NPT hole directly behind the fuel pump. I am wondering how long of a heater I can put in there (how many inches)? Also how many watt heater? I do understand that there is a heater in the hose in the front of the motor, but I think that one directly in the block would be a better option. Any help would be appreciated.

I'd recommend the one from the factory. It is plenty adequate and I wouldn't recommend anything different. Larry

I just bought one from Agco for $68. The element is about 2 inches long. The box did not have a wattage rating for it.My 1855 has a Perkins in it, so I had to ask the dealer for a block heater from an 8700 White combine.

I have a super 55 diesel that has not ran in a year. Now it does not pump fuel to the injectors. I have fuel to the injector pump. It has a Roosa Master pump. Thank you.

I have had a similar problem with my super 55diesel. Have you tried bleeding the injector lines? If there is air in the lines you get a vapor block. In this freezing weather, you need #1 fuel or anti gel so you can make the fuel flow. Good luck.

Its 60 degrees and I have all the lines loose. I took the small plate off of the side and fuel ran out. I have an electric fuel pump on it.

You probably have a stuck metering valve. I think you should take the pump off and take it to a pump shop. You need to get it to someone who has experience with those pumps or you will have a mess. Larry


1855 lift arm

IP: 72.106.163.133 Posted on November 20, 2014 at 03:41:55 PM by Jerry Shannon

Hello Larry. I hope I describe this correctly. I have a 1855 diesel. 1975. I recently bought for the 3 point hitch what I was the hand crank piece for the right side ( standing behind the tractor) lift arm. I cleaned it up, greased it up and painted it. Looks new. I thought I would be able to use that self leveling piece and it would mate up with the clevis that came with the tractor. when I tried to screw it in to the clevis, it is a hair off and will not catch the threads. Threads are clear and clean and not stripped. Would there be a slight difference if one part came off a 1755 vs the 1855 if they are both class 2 hitches?

No. They should be the same. Larry


Vibration - 1855 diesel

IP: 50.50.175.24 Posted on November 19, 2014 at 07:11:04 PM by Bruce Griepentrog

Hi Larry, any idea what would cause a bad vibration when the tractor goes uphill or under load ? Clutch ?

Re(1): Vibration - 1855 diesel

IP: 172.242.134.43 Posted on November 22, 2014 at 08:09:12 AM by Larry Harsin

It could be the coupling between the transmission and the hydraul. It could possibly be loose main bearing in the engine. Does it have good oil pressure when the engine is warmed up and idled down? Larry

One of those bearings has to have a flange on one side, just like what was in it. You have to have that part. Larry

How do you change the fan belt on a 66 & 60?

Re(1): Oliver 66 & 60

IP: 172.242.134.43 Posted on November 17, 2014 at 07:09:45 AM by Larry Harsin

You have to loosen the 3 bolts on the crank shaft pulley, then open the groove up, then you can replace the fan belt. You have to work the fan belt over the fan blades. Larry

I am working on an 1850 Oliver with a 6 cyl Perkins Engine. The engine dipstick tube is damaged. Can you please tell me the engine oil capacity with filter change? Thank you, Dave.

It is approx. 12 qts. You should get an Operator's Manual. It tells you all of that stuff. Call the Floyd Co Museum to get one. 641-228-1099. Larry
