MY 1972 CASE D 450 TRACK LOADER has a Rollback valve to keep the bucket level when raised or lowered. It leaks, and I found the the bottom adjusting bar is missing, probably why it leaks in the first place. I can make a new adjusting bar if I really need to , but do I really need it at all? Will disconnecting it completely cause any harm. My manual states the if it is not properly adjusted it could cause a hose or seal to blow.
