I have been asked and authorized to pass this along.
Apparently, all units shipped to distributors/dealers in the last two weeks have the new counterweights installed.
PLEASE check your engine before ordering, as supply is, and will be, for the units made with loose counterweights, and some have been installed!
Place locomotive on flat surface or track, grab the left and right counterweight on any axle but #3, and rotate in opposite directions.
BAD ones can be 20° or more, new ones less than 5, often just a rattle, and that’s with the screw loose. With the screw tight on new counterweights, there will be no play. On old counterweights, screw tightness does not matter.
Thank-you.
“Another problem is that some of the consumers are not even taking the unit out of the package before asking for parts. We have replaced the counterweights on all units we have shipped out for the past two weeks and now I am afraid that they are asking us to replace the counterweights on units that have already been corrected.”
