Rotor Replacement Help!
I am going to replace my cap and rotor on my Stock big block merc distributor(1989) and have seen some posts on here about gluing the rotor on. Is that the correct procedure? What type of glue should be used? How do you get the old one off without breaking something (assuming it is glued on)?
Please Help!

TBIV ignition? Tuff to get off, huh! I just put a chisel to it and broke it off. Then I sanded the shaft down so a new rotor would fit snugly but stll come off. I didn't use glue on the new one.

Blue locktite for sure, if it starts moving around it eats the plastic inside the rotor quickly and your timing starts jumping all over. If your timing marks arent steady and stable, it probably the rotor.

The problem is the plastic ribs inside the rotor bore wear and the rotor starts to move on the shaft. When this happens the timing jumps around. The merc manual says to pull the distributor and do it upside down so there is no chance of locktite running down the shaft and locking the shaft but ive always done it in place, just be careful and dont use too much. Im sure if merc backed off on its recommendation of locktite it was becasue of people using too much and locking the shaft to the dist . Do what you will but after a year, check timing and if its jumping around, the rotor is loose. BTDT.
