do you have to pull the front axle to remove the steering motor. and where is the plug to bleed the air in the steering valve.

would the leaking steering motor bottom seal cause the steering valve to not work properly

A leaking steer motor lower seal would/could be a sign of motor piston seal leaking, also if the steer pedasel or arm bolts are a bit too long they can hurt the seal, they line up with the seal...

It's not necessary to bleed the power steering . Just cycle it lock to lock several times . I've done steering since 1963 and after a few valves and steering motors found it was a waste of time.

I'm sorry but I determined I inaccurately labeled the bleed screw in the other photo I posted. Bleed screw is key 10

the reason im asking is the wheels are turned all the way to the left and if you turn the steering wheel to the right nothing happens . i figured there was air in the steering valve . any sugestions

Rarely is it necessary to bleed them, your steer valve needs resealed and re-calibrated,some things wear in them that will make the adjustment change,the result is the valve will open to let steer one way,, but won't open to steer the other. You will need to remove the valve out of the dash area,,not a pleasant job,,then take it to some one that knows how to deal with it,, most Dealers don't know, and if they do they will charge an outrageous price to do it. I can do it for you here and bench test it for $130 parts and $250 for labor and bench test, I do several each week here

You don't remove the steering motor unless it is broken. Remove the front axle and a side frame. I always remove the RH one. Remove the steering gear and the piston plugs then remove the pistons.
The bleed valve is on the LH side of the steering valve.

Today's Featured Article - Fordson Model N: Field Service Operations and Lubrication - by Anthony West. The daily or weekly servicing of any vehicle is of the utmost importance, and in days gone by when our favorite tractors were doing an important and Commercially vital job on the farm, these service operations would make a major difference to the running costs and economy of the farm. This being so, it surprises me to see how many enthusiasts attending rallies, shows etc, seem to be unaware of the importance of this constant attention. Possibly the modern machine with its 6,000 mile or even once ... [Read Article]
