Ordered up some cunningham machine door pins, rollers, and roller bars.
Talk to me about pinion seal replacements. From what I've read and looked at it, it shouldn't be that bad. Scribe a mark across the pinion shaft, nut, and yoke. Remove nut, yoke, seal. Install seal, yoke, tighten nut back to where marks line up. I could go and get a beam wrench and see what the rotational torque is before hand if I wanted to be double sure.
