Lift Pump for WD45D

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   About 10 years ago a member of this forum was good enough to sell back to my father a WD45D that my father traded off at his grandfather's dealership back in 1970 or so.  That WD45D was "my" tractor when I was growing up.  I inherited it when Dad died a few years back and it is finally setting in my shop.  The tractor ran very well when Dad got first got it back, but Dad's health failed soon after and it sat without running for more than 5 years.  When I drained the oil i found fuel in the pan.  Research leads me to suspect that the lift/supply pump is a probable source of the leak.  Anybody know where i can find a replacement?

	Have you seen Tom's site? https://www.allis01.com/ He has a lot of pictures and info on these injector pumps, including a suspect o-ring that can let fuel into the oil. https://www.allis01.com/fossto/56WD45D/ac-wd45d-PSB.html
