Does anyone have any idea what causes the steering on a 2840 to drift to one side, usually to the right. thanks

The 2840 doesn't have a seperate steering valve or motor as described. The steering valve and cylinder are in the steering column under the steering wheel.

The first thing to check is the bolt that holds the pitman arm to the shaft that comes out of the steering cylinder bell crank. The bolt is under the top tin round cover, in the clutch housing. If the bolt is tight, it is probably an Oring in the valve housing under the steering wheel. There are 6 of them in grooves in the housing. I use a sharpened welding rod to pull the old ones out, and 2 semi sharpened welding rods install the new ones.

To get the valves out , loosen the the jam nut on top of the column under the steering wheel, unscrew the adjuster nut, turn the steering wheel to push the valves up, and pull the valves out. Look down the hole, the Orings are in there, hard to see and a little trouble to get them in.

THE 2840 THAT I HAVE DOES NOT HAVE A STEERING MOTOR,NOR DOES ANY 40 SERIES TRACTOR THAT I HAVE HAD HAVE A MOTOR IN THE STEERING SYSTEM. THEY DO HAVE O RINGS OR, SEALS IN THE STEERING COOLUMN WHICH CAN BE REPLACED WITH A COAT HANGER OR OTHER TOOL. NOTHING IN THERE REFERED TO AS A MOTOR ! AS FOR THE BELLCRANK IT IS UNDER THE FUEL TANK IN FRONT OF THE TRACTOR , THE BOLT YOU REFERRED TO IS IN THE STEERING ARM IN THE CLUTCH HOUSING THIS DOES NOT CAUSE THE STEERING TO DRIFT BUT WILL ALLOW A LOT OF LOOSE MOTION IN THE STEERING. ALSO THE ARM YOU REFERED TO IS NOT A PITMAN ARM , IT IS REFERED TO AS A DRAG LINK ! i WOULD APPRECIATE ANY HELP ON THIS SUBJECT . DONT NEED SHADE TREE MECHANIC'S ADVICE- NEED HELP

Sounds like the seals are getting bad on the steering motor or the steering valve is hanging up. to check the steering motor take the plastic return line off of the top of the steering motor. put a block of wood between the steering arm and the frame on one side of the tractor have someone start the tractor and turn the steering wheel in the direction that will caust the block of wood to stop the wheels from turning. have them keep turning the wheel in the same diriction causing the main hydraulic pump to go out of stroke and then watch the fitting where the line has been removed there shouldnt be more than one drip every 5 seconds if i remember correctly. once you check one side then check the other in the same manner. if there is not excessive leakage at the steering motor then it could also be the spool in the steering valve is sticking off center, im not sure where the valve is located on a 2840 but there are four steel lines that should go from the steering valve down to the steering motor and 3 or lines from the steering wheel motor/pump. maybe some one can tell you the exact location for that model. but once you find the valve you can take the side plugs out of the valve and pull out the spool and look at it and check for wear or scoring. be careful not to get any dirt inside the valve and make sure the spool goes in the same direction as it came out. if there is scoring on the spool then you have to get a new steering valve. otherwise clean the valve up real good and put it back to geather some times cleaning it up cures the problem. Chances are unless you have a leaking line that your problem is in one of those two parts.

Mike w J you described where the main hyd.pump is. I have 30 & 40 series tractors but none with a steering arm attached with 4 bolts, the tie rods attach to a bell crank. I still dont understand what was refered to as a steering motor.

OK if you look under the tractor front end where what you call the bell crank there are 4 3/4 in bolts they take an 1 1/8 in. wrench to fasten the bell crank onto the motor it is bolted between the frame rails if you don't want to take my word for it get a book

Jerry : the info you are getting on some of these post is worth what you are paying for it. what mike w j is calling a bell crank is in fact the front axle support part # 28246 which is mounted with the 4 bolts he described to the front of the engine, and in fact the 2840 does not have rails! . The bell Crank Part # 19361 in fact mounts on the axle . it is App. a 1.5 inch pin with 3 cast iron fingers leading off of it, two of these , which the tie rods attach to , and the other is for the drag link. I dont know what is referred to as the steering motor. the steering column, is referred to as the steering valve

I said in my 1st post that 10 20 30 40 50 series had the steering motor with maybe the exception of maybe the utilty tractors like the 2840 and so I went to JD web site and looked up 2630 and 2840 tractors and they do not have steering motors but if yougo there you will find that starting at the 3010 to the 4850 and maybe later without MFD does have a steering motor I just tried to explain where the steering motor would be if it had one
