I need to change one of the pulsars on my 322. I figure I just as well change all 3 once I am in there. How is the best way to get in there? I assume I must take off the electric clutch and the front drive pulley on end of crankshaft. How do you get the pulley off? How do you hold the pulley tight while loosening the bolt on end of crankshaft? I assume once you have the bolt loose then you must pull the pulley. Once the electric clutch is all taken off, then you probably have access to the timing cover. I have an old tech manual but it seems very vague for this procedure. I want to avoid damaging anything.
