    My dad has the parts to fix the fuel injection pump for a Ford 4100 tractor. But he needs a diagram on how to put the pump back together. Does anyone have a diagram or photos or tips???

    Thanks in advance!!!

    For a parts diagram, go to Messick's.com on the internet. At the top of their home page:

    - Click on parts diagrams
    - Click on New Holland Ag.
    - Enter your model number (4100)
    - Click on 1975-1981 4100
    - Ckick on fuel systems
    - Click on fuel injection pump

    Ebay often has service manuals for sale for Cav injection pumps. A pump manual would certainly provide much more guidance than a parts diagram. You would have to be careful to select a manual representative of your pump model. Re-sell the manual when you're done with it.

    Another thing - there are three timing marks under the timing gear cover that must be aligned when you reinstall the injection pump.

    I can't figure out how to print it :( When I print the page, it's only a portion of the diagram.

    I'm checking ebay now!
