Any loco purchase should be followed with, especially on these worm drive engines, a thorough disassembly & lubrication. The motor shaft, worm & worm wheel, axle bushings & side rods are all pretty critical ares to service with modern synthetic oil & grease.
Hi, thanks for your help. I am new to the hobby, before visiting this forum or finding out about ERR, taking apart my trains wasn't something that really crossed my mind I should clarify that the grinding sound is less "mechanical"-sounding (like gears grating together) and sounds more like an intense electrical buzz.
That being said, do you have recommendations for oil and grease? I'm assuming the Lionel Maintenance kits aren't up to the job of maintaining internals. Thanks again for your input.
