Wow, that's beautiful work. Machine shop porn!
I've noticed that as well, the drum goes too far.Good stuff Andy. Nice to get the beast back on the road running sweetly. I'm also keeping an eye on my gearbox sprocket. As I expected, the Loctite stuff I applied did nothing and when I had the cover off I gave the sprocket a wiggle and sure enough there's the slight rocking play.
One success I think I can confirm is that I've completely cured the tendency to occasionally remain in 2nd after I'd changed to 3rd. While it was 'mostly' fine, I was still getting errant shifts. So i adjusted a little further and last night it was faultless. Touching wood. Very interesting that the solution involves the reverse of what you'd expect ... assuming the pin drum wasn't rotating far enough to set the hook to pick up for the next shift - but assuming wrong. It was actually going a tad too far, with the same result - pins not in place to engage with the hook. I would have expected the detent, roller and spring in the selector drum plate mechanism inside would click it into place, but seems not. Anyway, it was nice to flick the lever with full confidence it would shift.
Reminded me of an of 50s British B&W film about Spitfires(?) breaking the sound barrier - pilots hauling with all their might on the lever unable to pull out of a dive and crashing helplessly into the ground. The test pilot in the film did the opposite and pushed the lever away from himself and the plane pulled out of the dive.
Compressibility: the transonic shockwave moves back onto the elevators locking them solid. Using the trim tab is often the only way to get the nose up. This is also one reason they went to the full flying elevator/horizontal stabilizer and hydraulic boosted controls.Good stuff Andy. Nice to get the beast back on the road running sweetly.
