@Sitka posted:Bill I have mostly PW and a couple MTH PS-1, Those PW Turbines I have when I buy I tear them down and degrease, I get good performance when they pull those williams cars, (or Railking) plus those cars have alloy seats that I added and the cars are much heavier now, If CAPPilot or a PRRronbh, see this I'm sure they can help you on that motor issue.

I don't think it's excessive friction in the driveline of my MPC-era Turbines (although MagneTraction can cause friction problems with side-rods rubbing against drivers) as the driveline turns quite freely with the motor removed and I use Yamalube moly grease in the worm gear box. The locos even "roll" fairly freely on the track when pushed by hand. They also "keep their cool" when running alone or even when pulling the easy-rolling Lionel FARR#5 freight consist they were intended to pull. There just seems to be a load "threshold," like my Williams Congressional consist, that sets off the overheating problem. As I hinted in my previous post on this, Lionel apparently had production problems with this loco when they moved it from Mt. Clemens to Mexico and the motor quality may have suffered. What PW "generation" are your Turbines?
