Have it identified, It's Physical appearance is that of the MDG5500AWW with the touch pad panel, not sure if the Neptune was only Produced in 2006 or if it had a run of years thus producing variants of the same Model before the end of its production run? I'm fairly confident even with slight changes being made from model year to model year the majority of the parts remain interchangeable, so I hope anyway....
The drum IS pretty scared up so that's an excellent idea of flipping the drum around the other way after installing the new Drum Slides, much appreciated.
This particular machine doesn't appear to have the full circle plastic drum "Bearings" that most dryer drums seem to have on either end of the drum, or are they missing on this machine, leaving me with yet another couple parts to purchase for this guy?
I did find the Drum Slides @ RepairClinic.com for $20.15 Each (expensive little things) with the Dryer requiring 2 ea of the cork under pad along with the plastic slides themselves, noting that the pop rivets are included, for $20.15 a pop they sure better come with the dang pop rivets!! They actually even have listed a single Pop Rivet @ a cost of something like $24 or $27 bucks each!! Now that's one expensive rivet!! It has to be a glitch in there online system, they can't possibly be selling a single pop rivet at a cost of $25+ when the whole slide is just over $20 bucks, or could they??
Also needing to be replaced are the Front and Back Felt seals, they are warn pretty thin on the drum side and don't appear to be up to the task of creating a seal as intended. I did get a hair brained idea of flipping them over, putting the half that had been inserted into the holding clips towards the drum side with the bad half now being inserted into the holding clips. Not sure if that will work but figured it's worth a try, can't hurt to try it, worse case scenario, I'll have to order the felts, nothing lost. I don't see why it shouldn't work?
Thanks again for all the help and information, I will update this post as things progress.
