Hi.

I noticed something interesting in my picture. [8D]
Does anyone know if UP 844 has retro fit roller bearings or fitted originally at the factory. I don’t remember see anything like these bearings on other locos and they appear to have automatic oilers??

Have fun

Lee,

844 was a very new engine and I suspect that the drivers have roller bearings from the factory. I suspect that UP has upgraded the engine over the years and it has had heat sensors added to many of the bearing points.

Why not go out to the UP Steam website and ask them?

I believe the UP’s FEF-3’s were delivered with roller bearings for the trailing truck and the tender axles. That includes 844. Driving wheel axle bearings were surely roller bearings, also. I’ll even throw in the lead truck axle bearings, though I don’t know for sure

They are factory equipment. Search for in service pix and you will see they had roller bearings.
