Just wondering if anyone can say for sure whether the depth of the crank pulley differs between a mid 70s cast crank 440 and a forged crank 440? I pulled a 440 out of a W200 that was a cast crank motor and rebuilt it with a forged crank and the matching forged crank balancer. My research indicated that I would be able to reuse the four pulley crank unit from the original motor despite having swapped the crank. Now upon reassembly, it looks like the accessory pulleys are off by a small amount, and I'm not sure whether its due to bracket misalignment or a different pulley depth. Any help and/or pictures would be appreciated.
