What type of fluid goes in the power steering pump?
Has alot of play in the wheel when turning. Do these
cylinders go out or what could be the issue
 
Hi,
Assuming that you are in the US. If US 230s have the same PAS system as UK models then you will have a steering cylinder on the rear side of each side of the front axle. This is actuated by a valve attached to the steering column just under the steering wheel. When all is good the steering is actuated by the initial movement in either direction of the steering wheel. This actuates the valve and sends pressurised oil to whichever side of the cylinders is required. Observe the operation of the spool in the valve when the steering wheel is turned in either direction from neutral. The spool should either move up or down. If you can turn the wheel without moving the spool there is wear in the top column bearing. You should see the steering wheel rising and falling. This is happening instead of the actuation taking place.
To adjust; remove the steering wheel, a puller will probably be needed but on older tractors it is not uncommon to have to cut it off with an angle grinder. With the chrome cover,felt seal and key removed you will have access to the top nut tabwasher. Flatten the upper part so that the nut can be undone. It is a good idea to make a spanner from a piece of 1/4" plate as this will be needed to make the adjustment afterwards. Remove the lock nut tabwasher, bearing nut and balls and the lower cone. Look for wear in the nut face and cone. Replace as required. Reassemble and grease. Jack up the front of the tractor so that the steering can be turned easily. Adjust the bearing nut so that it has slight play. Fit the tabwasher and locknut and tighten the locknut lightly. The play should now have disappeared. If it is still there tighten the lower nut slightly and then lock it. Tempoarily fit the key and steering wheel and ensure that there is no tightness from lock to lock. Check for any wear in the pins and eyes of the adjustable link. If there is wear present new parts should be fitted. Tighten the locknut with sensible force and bend the tabs over.
Adjust the link so that it just fits the valve yoke and pin. Check the operation. Any movement of the steering wheel should now actuate the spool. There should be less than 1/8" movement in both directions. Replenish the oil and test.
You may be losing oil from the steering pump into the engine due to a faulty pump seal. Check your engine oil level as well. In the UK we would use Dexron automatic transmission fluid. The red oil.
Let us know how you get on.
