I picked up a used but original Huffy bay pointe and am preparing it for the new season with basic tune up and tires, but the 3 speed no longer works after I took off the rear wheel.
Using the search feature I found the diagram for a cartridge type Shimano 333 which, I think, is what I'm dealing with. I have never done any internal bicycle work before and wanted to avoid getting in over my head.....

I removed the rear wheel and took it down far enough to clean and grease the ball retainers, which required removal of the axle, spring, and keys. I slid the hub out and didn't mess with it but when putting the axle back in I DID NOT have two keys. This is probably why the 3 speed doesn't work but the diagram and parts list confuse me. The diagram for the cartridge type hub includes two #39 keys, whereas the other style includes two separate parts #38 and #39.
At any rate, it will take me less time to fabricate a replacement part out of scrap metal than it will to find it (I was over a work bench and don't remember losing anything) but I still do not know the proper assembly procedure.
How are you supposed to orient the keys in the axle, and how does the spring sit installation? Is there a positive engagement with the hub, or should it slide in effortlessly? I have no idea what I'm working with here.
Once the hub is back together how do you adjust the shift cable properly with the bellcrank and pushrod?
