Dunno. A light tap with a punch is how I got a pin to pop right out, though. (Actually I tried this after Mark Koors told me about it, just to see for myself how light a tap would do it.)

As I mentioned in a previous post, we found that bonding the pins in place with Loctite 680 did not work as well as we had hoped. Several pins were loose after 18 matches.

I have ordered some Loctite 638, which is apparenty stronger. I'll let you know how this works out. We are setting up a transmission under load and will cycle it back and forth for 20 minutes or so, then check the pins.

We are also getting a few plates welded, and will check these also.

We will update this after the autopsy.:eek: :yikes:

Our autopsy showed 4 out of 5 pins had fallen out of the final stage and the pin holes were grossly enlarged. Also, the planetary gears for the stage were missing teeth and were unusable. We have bought new carriers from Banebots which they promised will not have this problem with the pins. Time will tell if newer is better. We have 2 spare transmissions and some parts but are nervous about it.
:eek: :yikes: :ahh:

The welded plates did not work out. The heat from the welding warped the plate slightly, and made it unusable.

We will run some tests this week on the Loctite 638 plate.

Well, after NJ and Buckeye on the new plates - as received from BaneBots just after ship date - no failures on any of the four transmissions. We'll see what happens at the Championships.

Don

Is this with the center-punch method that you posted earlier? If so, then this is good news for teams without welding capabilities. :)
