A week or 10 days ago I was looking for a I & t manual to adjust the linkage on the lift chest. Found the use of one (FO35).Tractor is back together and running. Every thing functions as it should with one exception. I now have a (constant pumping) -- MF term-- position at the very top of the lift lever were the Ford operators manual says you over ride maximum lift. I can live with that but was sure something would be different as the adjusted lift chest according the the I & T manual made the adjustments quite different then they originally were! Either the linkage is bent or the I & T manual is not correct. I can see why the system does what it does but didn't figure out what the problem really is? OH,I saw here earlier someone pulling the plug for the unloading valve. In my case, I though I might be loosing threads in the plug or pulling bolt as it pulled so hard, but persistence prevailed!
