064/066 Cranks

[blsnelling]

Aren't there two different cranks that work in the 064 and early 066 with metal flywheel? It seems like I remember reading that they increased the size of the big end rod bearing. If so, what were the PNs for those two cranks, particularly the larger one? Any info would be appreciated.

Brad,
According to MediaCAT there are only two cranks for the 066. Early (read metal flywheel) is #1122 030 0407 this was replaced with # 1122 030 0408 (read poly flywheel) and you are right the new one also has a larger bottom bearing.

I should search my own files before posting, lol. The 1122 030 0406 was replaced with the 122 030 0407, which increased the rollers in the needle bearing from 12 to 13. If I read the tech sheet correctly, the 0406 was used in all 064s. The 0407 became standard in all 066s. I just bought a new 0407 for $62 to put in my 064

If before X 29 588 022, it'll have the same crank as the 064.
