Many thanks to TT and GrayRacer for helpful info and straight facts. I've decided to update my crankshaft from the '00 keyed balance drive gear design to the splined joint design. The key slot in the crank had too much slop and would wear a new key within 1000 street miles. Now that I have the cases apart, I'm looking at all the gears and shift forks. Shift fork #1 is clearly bent, so I will replace it and the related pinion gears. I'm not so sure about the other shift forks, so I would appreciate some advice based on these pictures. Shown is shift fork #3 with a slight trace of wear between the tangs (the crescent shape) and 4th wheel gear, specifically the dogs that engage 3rd wheel gear with a slight rounding of the corner. Should forks and gears that look like this be replaced? Thanks for your help!
