Alright, so I got the transmission apart, everything went very well. Got everything organized and the collar bearings?(Outside ones?) off the main shaft. and that shaft is coming apart very well. I stopped for the night though.
My question after looking at everything is. The secondary shaft, there are bearings on the ends of that. They are tucked up under gears and I think its going to be a pain to find a puller to fit up in there. They don't seem bad at all, so I might not bother replace them? Or I will modify a puller to work.
Sycro's appear to have basically no teeth left on the inner taper. Testing them, they don't even close to clear a .6mm feeler gauge (spec out of the manual).
The new ones are very close to not clearing the same .6mm though, so that was confusing. The new ones have very large teeth on them compared to the used ones though, so I feel confident that was the issue.
next issue was the 4th gear pop out, no bearings look bad ect. I can only assume that possibly the small detents under the shifting fork drums(on the main shaft) are worn out? or the syncro its self was causing the pop out issue.
After seeing how easy these transmissions come apart, I can always do it in the future if there are any other problems, I plan on throwing the rebuild kit and and seeing how it performs.
