My bad. Was just reminded wasn't quite explanatory enough. Funny because I was just talking to Scot about this same comedy of errors. Here goes.
Took it all apart right after the parts got here. Gutted except for removing the main gear itself. Was tired and called it a night.
Next evening went out and grabbed my OLD trusty large snap ring tool that's been used inside of other trannies for years. Apparently too old. Was an appropriately sized tool. But one of its nipples snapped off when squeezing the big 3.5" or so snap ring that retains the main gear.
No place in town had large snap ring tools in stock. Waited three or four days for a tool to show up in the mail.
Evening it arrived went back to the task. All going well. Gears in. Then suddenly realized the trap door on this gear set is Dyna.
Part number on the box is touring. Cheat sheet has the same part number. All the rest of the guts are interchangeable. I'd just not noticed the little ear sticking out on the trap door intruding over where the oil neck bolts on until it was actually in the case and actually sticking over in the way.
Next day called the dealer that sold the gear set. Was immediately apologetic and asked what I thought a fair solution was. I asked if they'd supply a touring trap door. Instead they're cutting a refund for the cost of a trap door which I can use to purchase the part wherever. So I can't complain about their willingness to make it right.
Changing it will take another tool purchase from George's garage that I'd not expected to need the first time through. So it's not without some expense. The dealer was good enough about the problem there was nothing to get upset about. Until, that is, I realized about 36 hours after finding the problem that only about 24 hours before discovering the old 6 speed gear set, with the trap door, had gone out in the trash.
It was ruined. Ugly. Wouldn't need any of it. Useless in every way and only setting in the way. The only piece that would have been reusable was the trap door. Which was exactly the part I'm now waiting on. Once that dawned on me I got a little cranky for a few hours.
