It appears to me that they press ball bearings onto the axle ends then the truck simply drops onto them and the lower bar retains them?Andrew Pugh wrote: ↑Fri Jul 15, 2022 11:46 am That style of retaining the bearings can’t be good for bearing life, but it may not reduce it enough to matter. Neat to see some of the big stuff!

Re: Visiting the WF&P in St. Louis
Yeah that’s what it looks like to me. Usually the outer race of a ball bearing is supported by a bore all the way round its circumference. This install puts a point load on the outer race. But like I said, it may not change the bearing life enough to matter, and they look pretty easy to replace.

Re: Visiting the WF&P in St. Louis
That's the way the big ones work, though they are double race roller bearings. When you go in the ditch, the little ears at the bottom of the truck frames generally break off, and the wheels fall out. Sometimes, you'll even see trucks under a car without the little ear, just sitting on the bearings.

Re: Visiting the WF&P in St. Louis
I realize this thread is a little old, but thank you for visiting and your interest in the WF&P David!
Since your visit last year, myself and several other volunteers have progressed nicely with 4-4-2 #300's rebuild. Here's a couple photos showing about where we stand. Most recently we completed a test run of the chassis with the brand-new trailing truck. Since 300 went out of service in 2002, the original trailing truck was taken and put under 4-8-2 #928 to expedite its completion in 2006. As #928 is one of our main workhorses, we did not want to put it OOS to reclaim the truck. Subsequently a new one had to be designed and built for #300.
We're pushing along getting the valve gear and running gear completed. I'm hopeful to have it running on air by February. Assuming the boiler comes back from repairs by then, I'm confident we may well see it run next year.

man, that's a good looking locomotive right there! Glad she's going to be back in service soon.
