Jd 70 power steering

[Big jd 70]

I have a new to me 1953 70 gas the power steering has a hard spot when first starting to steer let or right once the wheels start to move they move easily.any one got any ideas on were to start looking

Is the hard to steer spot only there when the when the wheels are straight?? Or does this spot follow wherever the wheels are turned?? Example: steer the wheels halfway to the left or right and let go of the steering wheel. Grab onto the steering wheel again and turn it back and forth and see if the bad spot is still there.

It really doesn’t matter which direction the wheels are pointed. It just when you are going from one direction to the other also it’s more noticeable the faster you turn the steering wheel. I am wondering if it’s pressure related or not this is the first 2cylinder Deere I’ve been around

My Moline does the same thing. If you make a quick direction change , it'll fight you for a split second then work good. I just got used to it being that way.

There is a JD service manual dedicated to just power steering .
There are springs that push the valve inside the valve body . If the valve does not move far enough or fast enough . You are feeling the gear to gear redundant manual steering system .
Your 70 was built after April 1954 iirc to have factory PS .

The 2 Cylinder power steering manual for Waterloo built tractors is SM2050.

Service manual SM 2016 is for earlier power steering systems (50, 60, 70 and mid 20 series tractors).

SM 2050 is for later tractors (mid 20 series through 30 series). However, your 70 could have been converted to the later style worm gear and actuating cams which isn't talked about in SM 2016. I'd recommend getting both books.

There are other places then Steiner.

It's really hard to explain how everything works in these systems without actually holding the parts in your hand. My guess is there's slop/uneven wear in the actuating cams that's causing your problem. It's really hard to get those cams to work right if they're not smooth.

Thank you all

The SM2050 manual covers both the early and improved power steering thus replacing the SM2016 manual.

I don't think power steering was avalible until late 1954. If it has factory power steering it's probably a 1955 or 1956
