G,Day massey Lady.The first thing to check is the Power steering filter it is inside the pump reservoir right hand side round with a square hex pfiller plug ,remove the centre nut and the reservoir the filter is inside there ,it is held in place with a spring and a pin You will find it easier to remove the complete rod with the thread use Vice grips it is not that tight remove the filter and replace ,or if it is not to bad give it a gentle wash out in petrol/gasoline remember it is a paper element ,if it is not to hard to get one i would replace it if not !!
The Next thing to do is check the power steering fluid level the power steering pump and reservoir is on the right hand side of the tractor ,the reservoir is the round cylinder with the Square drive plug ,with the engine stopped remove the plug SLOWLY there could be a little bit of trapped pressure in there ,this is done more safely with the tractor cold ,remove the plug and top up to the BOTTOM of the threads ONLY use dexron 2 ,auto trans fluid ,atf THE SAME POWER STEERING FLUID USED IN MOST GOOD CARS THE RED STUFF.
Start the tractor with the filler plug removed and if you can, turn the steering full lock left and right to expell all the air from the system keeping an eye on the level as you go remember do not overfill , If the power steering works the same both left and right all should be good ,if not and you find as mentioned that the tractor favours left or right.
First remove the transmission oil cooler the little one in front of the radiator ,it is secured with a long 5/16 " bolt with a wing nut just loosen the wing nut and pull the top of the cooler towards you and lift it up out of there leaving the hoses attached then get your favourite husband or your favourite wife to rock the steering wheel say 1/2 turn either way with the engine running and at the same time look on top of the power steering ram ,you will see a valve with a hex adjustable link secure by two lock nuts.
lets say the steering is easier to turn right than left undo one of the lock nuts that stop the long hex adjuster from turning : note one of the adjusters has a left hand thread You want to MAKE THE ADJUSTER LONGER do this by turning the long hex adjuster 1/4 turn at a time and try until the steering is BALANCED ,retighten the lock nut and recheck the fluid level remembering to fill only to the bottom of the threads ,this will allow for expansion when things get hot ,you will also notice that the power steering control valve leaks oil A seal repair kit is available and it is neither expensive nor to difficult to replace this may not stop the leak but it will certainly slow it down Ha,Ha.
If you check the fluid level and find the level low it can leak from either the Powers Steering ram seals, the transmitter valve or the power steering pump drive shaft ,if it is loosing fluid and you cannot see any obvious external leaks then it will be leaking from the pump shaft ,remove the pump and replace the seal using a GENUINE PART ONLY the seal is a double acting seal that is it seals the power steering oil in and also seals the engine oil out ,do not confuse the seal with a more common DOUBLE LIP SEAL it is NOT again buy GENUINE PARTS or take the sample seal to a seal supply company and make sure they know that the seal is special .
After all that if the steering does not work properly let me know and i will talk you through the factory setting procedure and checks, I hope this is not to confusing .
Happy Days .
