Hello all, My golden eagle engine stopped running. Whenever it does run, it is very loud and noisy and cannot haul any cars. It is a 6 drive power torque. Originally posted by bnsfIA - December 15 2014 :  09:17:36 AM

Originally posted by bnsfIA - December 15 2014 :  09:17:36 AM Is it a sort of screechy squeaky noise? If so, the little metal pinion on the motor shaft might be slipping. You might try to reinstall it with a pin-point sized drop of Loctite. Originally posted by Autobus Prime - December 15 2014 :  09:31:08 AM

Actually, it seems to run just fine in reverse, it just has trouble going forward. Originally posted by bnsfIA - December 15 2014 :  11:14:24 AM

I have a Tyco Alco doing the same thing. The pinion gear meshes with the other gears OK in reverse, but is slipping on the shaft so that it has become mis-aligned and when in forward does not mesh correctly (I think). Contributing to the problem are the other gears which in Tyco's attempt to save costs, are approx. the thickness of a piece of paper - with about the same rigidity. The last time I was fiddling with it I got so frustrated I was sorely tempted to launch it through the wall....so I stepped away from it It's waiting for me Originally posted by JNXT 7707 - December 15 2014 :  12:09:34 PM

Originally posted by bnsfIA - December 15 2014 :  12:36:11 PM But you won't know what the matter is, or how to fix it, until you check one thing at a time and eliminate the things that aren't causing the problem. Set aside the feelings for now and let's troubleshoot. GoinginCirclez has a very useful guide here: http://www.goingincirclez.com/TycoTrains/Guide/PowerTorqueRepair Your Golden Eagle was cataloged in 1980 only, so it should be a "Version 3" Powertorque at least. There should be 3 screws on the bottom of the motor truck, holding the cover plate on. The things to look for, given the noise yours is making, are: Cracked gears (visually obvious, the gears are mostly exposed to view) Gears with broken or worn teeth (look at the images on the guide to see what they should look like. Sawtooth shape or missing is not good). Iron filings or crud inside the motor housing Originally posted by Autobus Prime - December 15 2014 :  1:08:46 PM

Yep, looks like the pinion gear is stripped.. What now? Originally posted by bnsfIA - December 17 2014 :  08:51:55 AM

Also with that drop of lock tight. when you see a drop it is to much you just want the needle wet. I messed up a few of the tyco drives. frank Originally posted by toptrain - December 18 2014 :  08:27:35 AM

My gears came yesterday and the Tyco gearing is not 0.5 module metric gearing as I had hoped. I think they're in fact English standard 64DP gears. Anybody got a source? Pinion is 8 teeth, width is 2mm, shaft seems to be 1.25mm. Originally posted by Autobus Prime - December 18 2014 :  08:46:37 AM

I don't really need one, though, I'm mainly trying to find a source of supply we can all use for aftermarket replacements (ideally, stronger ones).

I am working on casting new ones in brass with an integral flywheel... stay tuned and i will let you know how it works. Originally posted by metalsmith1 - December 19 2014 :  12:30:18 AM

Originally posted by metalsmith1 - December 19 2014 :  12:30:18 AM Now THAT sounds interesting! I"m assuming the flywheel will have the gear molded in on one side, and then it's pressed on over top the larger drive gear, so it's hidden, almost like a watch gear drive. Can't wait to see the results of this! Wouldn't that be a neat trick? Jerry Originally posted by AMC_Gremlin_GT - December 19 2014 :  09:10:03 AM
