Chrysler Repair: 1984 Chrysler T&C mech. fuel pump, chrysler town and country, pulley bolt

Question
Roland - My brother has removed fuel pumps before but is trying to replace the mechanical fuel pump in his 1984 Chrysler Town and Country Wagon, 4 cyl. 2.6 liter engine.  He has the bolts out and was lifting it out when it got "hung up" on something.  He turned the ignition several times to turn the camshaft to see if that would free it up. Any hints what to do...does he need someone underneath the car to press on or move anything to free it up?  My boyfriend is a former mechanic and he thinks the camshaft may be the culprit. I mistakening asked Kevin this question earlier today and this is not his area of expertise..hoping you can help

Answer
Hi Deborah,
The '84 manual show the fuel pump just has a long rocker arm that extends into the engine, with a slight upturn and a flat pad on the end that is driven by an eccentric cam of the accessory shaft. I would try rotating the engine by hand using the crank pulley bolt, a socket, and a ratchet to do that. The position of the engine with greatest clearance for the arm is when it is at TDC of the number 1 cylinder compression stroke, so that is where I would move it to gain the easiest resistance to removal. He might want to remove the valve cover so as to be able to guide the pump rocker arm out of the head from the inside. Be sure to use new gaskets and RTV sealer on both sides of the spacer block. It may similarly be necessary to guide the rocker arm back into place from the inside of the engine.
Don't overtighten the nuts so as not to crack the spacer block.
