I have just discovered what seems to be a brilliant new lubrication product from Buffer Stop in East Preston.
I had despaired that I would have to replace at least two motors with questionable clearances as I thought they were on the way out.
A few drops of the "Silicon Swiss Navy Premium Lubricant" which appears in a liquid gel lube and the two locos have turned into the equal of my best performers, pulling more vehicles quieter and more slowly and I have saved myself trauma getting the motors for these units.
It is one of the better spends of $10 I have ever made in this hobby. Other locos are pulling a lot better with better slow speed control and I will gradually test it and apply it to the whole fleet as I circulate the locos for runs. No more LaBelle for yours truly apart from what I need for other lubes when I find the tubes!
