raymurph Posted November 25, 2020 Share Posted November 25, 2020 Hello all, I've just recieved a second hand us diesel dc loco off ebay and it makes a horrible grinding noise. Hopefully u can hear it in the clip below. Just wondering if anyone can help diagnose the problem, should I attempt a repair or just return. I am very new to this, 3 months at the hobby, this is my 5th train. Many thanks http://imgur.com/gallery/b9zxEr7 Quote Link to comment Share on other sites More sharing options...
irishthump Posted November 25, 2020 Share Posted November 25, 2020 That sounds dreadful! I have a couple of Spectrum locos and they’re not the quietest but there’s something wrong there. The gears sound like they are binding but it’s hard to tell without opening the loco up. If it was me I’d have a go at repairing it but if that’s not your thing then return it. If you decide to fix it post some pics here and we can try to help you out. Quote Link to comment Share on other sites More sharing options...
DiveController Posted November 28, 2020 Share Posted November 28, 2020 (edited) Occasionally you might have a broken gear but I'd wager that it has been sitting around for a while and is in need of lubrication with a light machine oil or similar. Should be easy enough to open up and clean and/or lubricate the gears and motor. Probably easier than returning it especially if you're responsible for return postage. @raymurphWhich loco is it exactly? Chances are, there's a youtube video to help you open it and guide you through the maintenance Edited November 28, 2020 by DiveController Quote Link to comment Share on other sites More sharing options...
Noel Posted November 29, 2020 Share Posted November 29, 2020 Lub gears and barings perhaps, suggest asking seller if they’ll take it back if lube fails or you are uncomfortable disassembling it enough to lube it. Send seller the video. Quote Link to comment Share on other sites More sharing options...
mmie353 Posted November 29, 2020 Share Posted November 29, 2020 (edited) I would agree with everyone advising lubrication. I am unboxing my locomotives out of storage at the moment on test track and I am putting a little lubrication on the gears to ease things. I have a couple of locomotives since the 90s that I running in again. It is making a huge difference to each locomotive. It would do no harm to open up and make sure everything is ok with the model Edited November 29, 2020 by mmie353 Quote Link to comment Share on other sites More sharing options...
raymurph Posted December 2, 2020 Author Share Posted December 2, 2020 Thanks for all the advice. I was able to take it apart and give it a clean which improved things. I'm waiting for lube oil and grease to come in the post and then I'll strip it further and lube everything more. Video of it now: http://imgur.com/gallery/BkUK9Qr Feels satisfying to have improved it, hopefully after a further clean and lube it will be as quiet as my other spectrum diesel. Is it advisable to strip this truck down further for lubing? Quote Link to comment Share on other sites More sharing options...
