Any words of warning for me before I remove the pump for rebuilding? Such as don"t do it, hire a professional.

Thanks much for any guidance.
 
Have your shop manual ready and do it, probably the easiest pump change you will ever do. I don't bother finding number one, just line up the marks, set the pointer on the flywheel and go, if it's out 180 degrees and won't start when you are done it only takes about two minutes to turn the pump to where it is right and you're done.
 
I guess I didn't ask what you are doing? Taking the pump off and going back on is a chip shot, rebuilding it could very easily be a different story.
 
Every one has their favorite way of doing this. Mine is to line up the timing marks that are on the hub of pump to pointer on pump and it should be at about 17 degrees btdc. Then I pull injection pipes off pump head and tie them up out of the way. Take cover off in front of pump, remove the three bolts. Pull throttle wide open, turn pump with a wrench normal direction of rotation while watching the fuel coming out of fittings on pump head. That way you know if it stopped on number one or number six. Then take all other necessary lines etc off. Other ways also, like taking side cover off and when the line on gear comes around you are nearing number one, then proceed till timing mark on hub lines up. If pump is twisted off, all bets are off, go for position of valves or just take your chances being on one or six when at 17 degrees btdc.
 
I'm getting ready to put this thing back together and it seems like there should be a gasket on this end (area of thumb). Yes/No

I like to use a little medium thread locker (blue) on the threads of the bottom cap screw. They have a tendency to loosen with time.
