    That is a life time of running.

      This is very encouraging. Thanks for reporting, Larry.

      Did I read gears for the Davenport? Dare I hope?

        From Bachmann, re: Davenport gears...

        "Hello, we will be sending out the gears in the next few weeks for you. Thank you for your patience."

        Also daring to hope...

          Good to hear that there is a fix for the gear problem woes.

            This is the first I've heard of Davenport problems.

              The davenports have had hear issues but not the failure rate tied to the rail trucks/buses, shays and climaxes. I have had one of nine davenports fail. All of my shays and rail trucks / buses failed. The Davenport is listed in Bachmann's replacement offer.

                I have one Davenport that failed with less than an hour of run time, and another that I haven't thoroughly tested. I bought the second for backup, before Bachmann made the replacement gears available. I figure it's a bit like a recall, may as well replace the parts with a track record of going bad, since the exact failure rate is unknown but seems probable given time. For me, it'll be difficult enough replacing the gear(s) on a naked stock loco, let alone one that's been "crtterized". It would seem that Bachmann heard about enough bad Davenports from the customer base to include it in their replacement program.

                  Thanks, Larry. Both of my buses are running. I've run each one for about an hour. Should I oil or lube them again now?

                    Terry it depends how much oil was still in the gear housing. A little goes a long way. As you now know it is easy to get the cover of and check so I would suggest taking a look.

                    I am glad your busses are running again.

                      When this topic first started my Rail bus was running like a champ so I didn't order the gears. Shortly after I set it on my display shelf. Well, I finally decided to get it off the shelf and run it during my up coming ops meet. I'm sure you already guessed what happened. It moved just a little bit and then nothing. I opened it up and all 4 bevel gears are split. So I fired of an email to the Bachmann On30 support email address. I sure hope they still support this because they don't list the gears in their online parts catalog.

                        Happy camper here today. The gears for my Rail bus and 2 Gas mechanical locos showed up today. I guess I wasn't to late.

                          Larry,

                          Oil or Teflon white lube...plastic safe stuff? I use the white lube, no more oil, the oil gets sticky...

                            I did not use anything there was enough in the gear case to do the trick.

                              Here is a belated update: the cover plate on the central gear box is NOT reversible (although it appears so on first glance). I recently replaced what I hope is the last split gear, and still had uneven running at slow speeds. The issue turned out to be the cover plate. There is an extended bearing support on one end, and a shorter bearing support on the other. The difference in height is only about .020”, so it is a little hard to see. For smooth running, the longer support should be installed toward the rear. It does make a difference in running quality!
