  • 1947 2N Hydraulic pump question(s)
  • First, I own a beater. She's not pretty but works for me. Lately my lift arms will slowly drop when the tractor is shut down. I am guessing the piston under the top cover needs work? Second, when the lift arms are raised to top when tractor is running I get a bouncing up and down with equipment attached or not. I think I should pull the cover and drop the pump and do a rebuild. Suggestions anyone? Does anyone have a nifty way to remove the arms from the pump when it is dropped and to re-attach? This tractor looks pretty simple but I am sure something is gonna bite me unless I ask questions. Thanks for any help.

  • The last thing I would worry about with your problem would be the pump. remove side inspection cover and see if leak down fluid is coming from the piston. The cam follower pin is probably worn. The first to do is to read and understand the FO-4 service manual.

  • Well, if you are talking about the cam pin #374072-S, that dont exist on a 2N. My F0-4 service manual makes no mention of a cam follower pin for the 2N-9N top cover. Is it maybe called something else? I have not got to check with the side covers off yet but I am betting you are correct with the piston call. No matter how bad the problem may be, its 100X easier than a John Deere!!!

  • No cam follower on a 2N but the lift control mechanism is supposed to kick the linkage back to neutral when the arms reach the top. Sounds like something is amiss in the adjustment/operation and the pump is not shutting off at the top of the stroke. FO4 describes operation and adjustment.
