  • Attaching control valve fork
  • The hydraulics on my 40 9n would go up, but not down. Figured the bottom of the pump was full of sludge... it sure was. Removed the pump and cleaned it up in diesel fuel. went it reinstall but can't figure out out to reattach the control valve fork. I removed the inspection covers and tried to use a hand through each hole to reattach the fork, but after three hours haven't had any luck. Suggestions short of paying a child with small hands to get in there and reattach it. Do most people take off the top cover to do this?

  • Does that have a special tool number and come in the tool pouch with the plow wrench? LOL

  • I always like the one, "re-install by simply reversing the disassembly procedure". A spreader stick is good.

  • Re: Attaching control valve fork
  • If a person did this often it might be handy to have a special tool. My thought is a spreader bar with a slight notch in each end to prevent slipping off and a handle/lever attached in the middle.
    Reach in and spread the forks by rotating the tool, align with the manual valve and rotate the tool up or down to close the forks.
    Any thoughts?

  • As I recall, Hobo posted picture of such a tool that he made a few tears back.

  • My kind of guy. I used to have to work with Kent-Moore Tool on special tools for GM automatic transmissions.

  • I've only done one once. I used a short piece of wood wedged between the fork arms.
    I wonder if a small spreader clamp could be used? I would be curious as to how they were done in production.

  • I have had the best luck with the two hand method, although this last time I got it by installing one side at a time with a long prybar through to the opposite side and pushing the fork out and owner the control valve.

  • Re: Attaching control valve fork
  • Here are my notes from installing pump in 51 8N a couple years ago

    To reinstall. Donít forget the base gasket!!!!!!!!!!!!!

    Put small block of 1 by wood to get control lever parallel to rear edge.
    Put trouble light by right side hole. Work on left side

    Use floor jack to raise pump. When it is up part way in case I tied 2 small ropes around transmission case to protect pump if it slipped off of jack.

    Carefully raise pump and drop rear end so hole in front of pump body will slip over PTO support. It is a loose fit but must maneuver back then slide forward. Raise pump into position and install bolts.

    Run pump bolts finger tight. Install PTO shaft and engage PTO. Crank engine over several times to turn PTO shaft and let it align with the pump, then torque pump and PTO bolts
