In preparation for Okteenerfest, I finally resealed one of my leaking gearboxes and planned to get it installed this weekend. Was having difficulty mating it to the engine so pulled it back out and found I cannot turn it by hand when in gear - I tried them all. In neutral, I can turn the stub axles in opposite directions and hear the gears moving and the shaft does not spin.
On the gearbox I took out, I can rotate the stub axles and the shaft spins (guessing it is in gear but not 100% sure). Can't easily change gears on it since I removed the shift console to use on the resealed unit. When I resealed the 'box, I removed the stack to change the shaft seal. Put everything back in and didn't have any leftover parts (IMG:style_emoticons/default/wacko.gif) Even watched Dr Evil's video. Any ideas on what might be going on?

UPDATE: I removed the nose cone and everything moves as it should in/out of gear. But when I replace the nose cone... it binds.
What should I look for? I have removed/replaced nose cones before without issue. (IMG:style_emoticons/default/confused24.gif) (IMG:style_emoticons/default/driving.gif) |

If I recall there is a spacer / thrust washer that can cause jamming of 1st and reverse if not installed in correct orientation?

I had the flat bearing on the wrong end (IMG:style_emoticons/default/dry.gif) Thanks for the suggestion. I figured that's what it was when I removed the nose cone from an extra gearbox and saw the order. Just got things swapped and works as it should. Gearbox is mated to the engine.
