Posting this for the benefit of anyone who hasn't
been into one of these steering systems. First
pic is one of the worn pins, I just flipped it and
put the worn part into the sleeve. The second pic
is the spool valve closed wheels forward. The
third is the spool valve position with full right
turn and the last is spool valve position with
full left turn. After repair and helix slot
adjustment, I took these on the workbench. I was
curious about the size of the opening with so
little helix slot movement. I was surprised at
how little the spool valve moves. Didn't measure
it, but looks like about 1/16 to 3/32 inch in both
directions at the most. The setup is back on the
tractor and working great.
