I had my steering valve/housing apart on my later serial number 1020, but got it together and to me it seems like I have a lot of up and down movement in the steering shaft, the one where the steering wheel will attach. I have a manual to follow and added shims to the thrust bearings to correct that end play on them. I have probably 3/16 inch up and down in the shaft as I turn the shaft which seems like too much to me? This make about a 1/4 turn free on the shaft which would be 1/4 turn on the steering wheel. Anyone having a 1020 or similar tractor, could you check yours without it running and see if yours is this way too? I did this all meticulously,being clean and checking things, but dont want to install it on the tractor if there is going to be a problem or have wander on the road. Thanks for your help
