I have been trying to get the distributor out to replace the pick-up coil (Hall Sender) and cannot get the distributor out. I have set it to TDC by the front pully, but noticed that the mark on the flywheel is a little off. Anyways, I can rotate the body of the distributor a full 360 deg. and if I pull on the shaft it will go up and down a little and rotate just a bit, indicating it is not all binded up with the cam gear, but the body of distributor will not come up even a milimeter. After many frustrating hours I started to the try brute force method by prying up on the housing with a considerable amount of force with no luck. Am I missing something?
I also tried tapping with a hammer as I pulled, jiggled, rotated...as well as having someone pull on it while I wiggled the crank pully back and forth. Since the shaft will come up and down a little (just a mm or two) and will rotate a few degrees back and forth I don't think it is a matter of the crank/cam position. Something is locking the body down but letting it rotate...
It is normal for the crank pulley to be slightly off when the disty is at TDC. This is because the disty hits TDC at ~6Degrees BEFORE TDC. So if the crank is at TDC the disty should be pointing slightly CW of the hash mark.
As for removing it...I don't have any experience...but did you remove the collar bolt (it's the one you would loosen to manually turn the disty when you are adjusting timing)? If you only loosened the collar bolt until the disty would turn the collar will hold it in place.
