Tractor Repair: 574 int. injection pump, international tractor, rocker arms

Question
I need to remove my injection pump on my 574 international tractor. It is a bousch pump. what do i need to do.  THANKS

Answer
To remove the pump the most important thing is to have the engine on top dead center #1. If you are having trouble doing this take off the valve cover and turn the engine over with a bar or ratchet on the crankshaft. Look for the intake valve to close and before the exhaust valve opens
both rocker arms should be loose. To verify that you have it right there should be a triangle cover on the side of the pump if you take it off make sure the two scribe marks line up(really hard to see). Take the square cover off the front and take the nut or bolts off the gear. Install a puller and pop the gear off. Don't turn the engine over when the pump is off.
