I have many older athearn loco's and some newer atlas and some life like PK2 like the Fa's and a GP 9 and have put the PK2 drive in a roundhouse RS-3 and in a atlas RS-11 from a used FA-1 since I had the shell kit and not an atlas drive or frame .
I noticed on a few later Life Like PK2 loco's such as the GP-20 and later GP-30's which I have to sell that the u_joints where improved where they used to be like the ones Athearn always used and A-line has as replacements .
One the older FA's I noticed the drive shaft couplings were warped or with broken tabs so replacing them with A-line or athearn parts improved the running on the loco's .
What happened to Life Likes site where you used to be able to but these parts ? The newer u-joints were much like a new design like a cars U-joint and workes very well but now I can't find them .
What are the options availabel now days, I have been out of the hobby for 6 years and a lot has changed .
I have all sorts of atlas and proto units of all sorts but sold most other than a few and many are rebuilds from bodies sold to fit athearn chassis from rail power . I have a good set of athearn Trainmasters and GP-38-2's I built into high hoods and a GP-30 from an old front range shell on a modified athearn chassis and a GP 38 rail power shell that I modified into a high hood and used cannon high hood parts just to replace the horrid rail power hood ends .
I am not up on all the new stuff and all the changes . i have no layout just a loco buff here .
I have atlas S-2's and S-4's one S-2 is the chinese model and the 2 C424's are old yellow box made in japan units .
I even built a Baldwin /EMD out of a stewart AS-16 nose and Life like GP9 long hood on an AS616 6 axle trucks and stewart frame and have two stewart AS616 athearn powered units .
