Power steering does not work turning right. what

is there any check engine light on
are all drive belts on
vvt has nothing to do with the steering
is power steering oil is full in the reservoir
Hi thank you for update
you can start the car and even while it is running the steering is the same, any chance the hose are not install the wrong way if you had removed, if you jack the front wheels and turn ignition on car not running can you turn the steering left and right or end to end see if this work? did you check the compression on the cylinder which is misfiring
Can you start your car and were are you based

Have you had this tractor for some time or is it a recent acquisition? The JD 4020 1969 serial numbers go from 201100-222159. Lazy power steering to one side has two commom possibilities, internal leakage in the control valve, Or, if the front end had been worked on, the tie-rods were not set to center the steering wheel when setting the toe-in. If that is the case, and the steering wheel is properly centered when driving straight or has fewer turns turning right than when turning left, the steering wheel was re-centered by removing it and resetting it on the steering shaft spline, in which case it is rarely perfectly centered. If that is the case, the control valve may not open much and restricts oil flow when turning right.
It is possible the steering cylinder piston seal leaks in one direction more than the other, or that the front wheel toe-in is wrong.

the grinding noise is from the steering pump going into overload and the pressure relief valve is working. If you have recently worked on the pump or steering check that the hydraulic lines have correctly installed It appears that when turning right the steering is trying to turn left.

This sounds like a bad valve in the rack and pinon. I just had a simalar problem on a Mitsubishi .. I replaced the rack with a A1 Cardone rebuilt rack and it cured the problem.. Rebuilding a rack is a job better left to the pro rebuilders.. you can call the teck line for A1 cardone and ask them what they think.

If you are saying the steering is difficult to turn you could have a blocked hose or a problem in the gearbox.
Or something in the front suspension such as a faulty ball joint.

Low on fluid ?? Air in system?? wrong type of fluid?? bad pump?? while car is running and in "park" try turning wheel from left to right all the way in both dirrections,, do this a few times then check for any leaks... then with engine "off" check your fluid level... if nothing fixes the problem then concider this> bad pump "OR" bad steering rack!! Oh please make sure that none of your power steering hoses are kincked or squashed restricking the lines !!!. Good Luck!!

fill to top with oil then turn steering full lock left to right a couple of times they have to be bled out ,oil will be a bit discoloured dont worry about it as its only an old car

My opinion is strain yes damage no. You know when you turn the wheel all the way to one side the tires are "grinding" into the pavement this causes you to give it a little extra gas to get the car to move...right? But I don't think that would cause damage. If I'm wrong then you have the worlds' worst engineered car!

Turning lock to lock as you describe is making the steering pump work hard since the wheels are stuck to the pavement.

I'm calling it B.S.

pipes fitted wrong

check your power steering belt. it may have broke or slipped off the pulley. if it seems ok check your fluid level. if it is still at normal operating level for hot or cold then your power steering pump may have just seized up and you may have to replace it.
