Posted about a wobble in my balancer pulley the other day. Finally got around to taking it apart again and after further inspection I would assume I’m missing a crucial part here. I think from a little research that the woodruff key is supposed to slot into that spot? There doesn’t seem to be anything for the pulley to slot into.

update: the guy I bought it off of didn’t align the washer right when he installed a new timing belt so he covered up the part the pulley is supposed to slot into. Looks like it’s damaged as well so a new one should fix my problem

 

2 Choices of crank gear - up to 1992, square tooth belt, 93 + round tooth belt. Both have a bump to line the crank pulley up with opposite the key in the crank. The slot in that washer (that looks like it's on backwards due the the witness marks from the timing belt) - lines up with the bulb on the crank gear.
