I'm curious about the UDPs. Now, if I'm not mistaken, the original part serves a dual purpose as both crank pulley and harmonic balancer, correct?





Now, my question is, by using the UDP aren't you running without a harmonic balancer?

Also, just to put my $.02 in here, since the original harmonic balancer/crank pulley has no bolt holes to assist in removal and the removal procedure is to basically pull it off by pulling on the outer ring (ie pulleys) this could easily cause this misalignment everyone is talking about here. The outer metal pulley portion is not directly connected to inner metal section, but rather is friction fit with what amounts to a large rubber band between the two parts.
