Good Morning, hoping to find some help. I have a gp35 item 11510 that the leading truck appears that the drive shaft coupling will no longer spin the gearing. I see the fly wheel turning. I was wondering if anyone had suggestions on how to fix that and if part # 6030 would need replaced? Or if other parts would also need replaced?
Thanks
Brett

There should be a drive shaft with a universal at each end. If the drive shaft is not spinning the universal on the flywheel end is probably bad. If it is spinning then your problem is either a bad iniversal on the worm end, or a bad gear. Are you able to see if the worm itself is turning?
Whatever the problem, shrink tubing is unlikely to fix it.
NWSL has a line of replacement parts that fit a variety of locomotives, but you have to know the size of the shaft if you are replacing a universal. Drive shafts of various lengths are available in the Bachmann parts store, but you need to look under individual locomotive listings until you find the length you need. They may be listed under a different locomotive than the one you had.
The problem here is that the old Spectrum/ Bachmann Plus versions of this locomotive have been out of production for many years, and many things have changed in the drive system since then. The newer GP35s do not have the split frame of the old SPectrum era ones, and other parts are probably different as well. That said, it is still a locomotive worth trying to find parts for.
