Getting planet gear pin to stay in/ Bendix 2sp auto
I have a speed Bendix 2sp auto that ive rebuilt and this one pin on the planet gear will not stay in. I don't know if it falls out during disassembly but I'm wondering if there is some method for getting it to be tight again?
There is a knurl that holds it in place. If it somehow spun and knocked the knurl down you could replace the pin. If it spun and opened the hole up in the driver you would need a new driver.
Not sure if you're able to make a new knurl or not, maybe green loctite.
I don't think you want it in there loose, will probably hit the bearings.
It would be best to ride down to your local Schwinn Dealer and buy a new driver, just like you did in the good ole days.
Obviously new parts are not as plentiful today as they were 50 plus years ago. Wash all of the grease out of the driver, gears, and pins, DO NOT USE BRAKE CLEAN for this operation. Take a six pack of beer over to your local car guy buddy and have him TIG weld a tack weld on the end of the pin away from the bearing surface. It will take him all of 30 seconds. The reason you were told to NOT USE BRAKE CLEAN is because it will give off a lethal gas during the welding process. Acetone is fine, it has to be squeaky clean to TIG. The TIG welding will not splatter like a MIG weld does.
For some reason I was thinking the pins go in from the bearing side.
But they install from the back side. You could probably get away with a few stakes from a centerpunch.
New and used pins and drivers show up on ebay often. I think you will find most of those seller are here on this forum.
I think I would try a new pin first then stake it.
