I have three of these guys, 4935,8753, and 6-18003. I planned on running one with the layout this year. None of them work. They all just grind and barely move. I cleaned the armatures and brushes, dabbed oil and still darn near nothing. What happened to these guys? The 18003 can’t possibly have more than 5 hours. Oh I greased them all lightly. Allinput/suggestions welcome. TIA
I find it odd that none of them at least move a little bit. When was the last time these units were run?
I ran into a similar problem several years ago with a mint gantry crane that was several years old. Took it out of the box, hooked it up to a ZW and, nothing. The gearboxes were full of hardened “grease” and everything was frozen solid.
For this reason I’d have to agree with BigAl; pull the motors and clean out and replace the grease in the gearboxes. Use some Lucas Red N Tacky. It all sounds a bit daunting at first blush, I know, but it’s really not difficult. And, if you take a few pictures during disassembly, re-assembly will be a snap. Good luck, and let us know how you make out.
