Yes, me again. So after fixing the TMCC issue, I was testing and noticed the driveshaft wobbling. Pulled it apart again and found that the rubber connector between the pullmor motor and the worm shaft has deteriorated and one of the quadrants of it has split. I looked on ebay but no luck. Whats a good replacement?

Thanks for the assist. In doing some testing I figured out why the rubber coupler was ruined... the worm gear drive shaft is bent. So looking for one of those as well. This thing was sealed in the shipping carton new. Pretty amazed that this thing was put together like that.
Something is amiss with this engine. You say it is new sealed in the box. I would question the person you bought it from. All the drive parts are readily available. I would also get the worm shaft bronze bearings as well as the thrust bearings and extra thrust washers. The rubber coupling insert and worm shaft are bulletproof so I’m not sure how they could have been damaged. Just doesn’t add up.
Rod, this loco was still sealed with the lionel shrink wrap. Definitely not the sellers fault. It was perfect untouched. I think it was just just a fluke where a bent shaft was just assembled in this engine from the factory. Would not have been noticed when they tested it before packaging as it did run. Just after I started running it after cleaning the rubber coupling became ruined. (If I remember correctly they tested the high end made in America stuff before packaging).
I have the parts on order. So hopefully a week or so it will be back up and running.
Craig, I hope all goes well. It is a great runner. Someone certainly dropped the ball on this inspection. Keep us posted. Remember to count the thrust washers on each bearing. There could be several for proper worm mesh.
Thanks. Even though the parts are on order, I decided to try my skills. Put the driveshaft in the small vice, used a straight rule I use for checking Qjet carbs, was able to straighten it out perfect (well measuring with a gauge shows a miniscule bend still). Took an old sketcher shoe that the rubber sole was detaching, cut out a block almost the perfect thickness. Hobby knife, sandpaper and made my own rubber coupling. Bit of trimming down almost perfectly round, right thickness, notched out the 4 slots for the pins and she is back up and running great. Once the parts come in I will replace them of course, but in the meantime, she is hauling passenger cars as she should have 23 years ago instead of sitting in the box.
Very nice...well done!
