Tips:
Lubrication:
I cannot stress enough that you MUST lubricate these cars out of the box. They WILL derail otherwise, trust me, save yourself the aggravation!
Be sure to oil all the journals, these cars can have a lot of drag if unlubricated. Most of mine came dry. With the metal journal bearings, I use a heavy oil.
Greasing the truck pivot areas, the main pivot and the curved slot. Make sure there is no hangups or rough spots, I use Hob-E-Lube moly grease.
Very important: If you have the new style trucks, they have a rib on the top of the truck that goes from one side to another. You need to grease where it rubs on the underbody, this is the main reason for derailments.
Mine derailed right out of the box. Many of the journals appeared dry. After lubricating the journals and the underside of the body where the side bearing rubs, all derailments ceased immediately.
I cannot tell you how many people complain about these cars, and if they would just lubricate them properly 99% of their problems would go away.
“Also, make sure the Journals box move easy up and down… May have to trim out the slots very carefully.”
I use on the axle bushing a drop of Penn oil, 40 or 50 wt.
Hope this helps… Mine can back thru 10 Dim. switches with no problem now.
