Advice on Oiling Tail Bearing on Vertical Mount Can Motors w Flywheels

I use the same oil, I haven’t had an issue getting an old Labelle pin oiler needle down in there on my son’s diesels….sometimes I find if I rock the wheels a wee bit, the flywheel will jump up just enough to get the pin oiler down in there…..no problems getting 85-140 at room temperature to push through an old Labelle bottle…..this has been my plight for quite some time now, 85-140 hangs around for a long time, and doesn’t evaporate off or simply run away like thin hobby oils. I use 85-140 especially on steamer’s side rods, crankpins, etc…..it hangs around for a long long time, and does an effective job,…..some of my locos have thousands of hours,….

I've never felt the need to oil the bearings on can motors.

In my years of experience with various motors, even with "oil-impregnated" bronze bearings in can motors, without periodic oiling motor bearings eventually go dry and start "squealing" due to precessional rotation of the dry shaft in the dry bearing. This, of course, rather quickly wears the bronze bearing to the point of being unrecoverable. I "pre-oil" new loco motors with 85W-140 and, as Pat mentions above, get hundreds of hours of operation between oilings and don't lose a motor due to catastrophic bearing wear. As I mention above, the oiler I'm using (it is a labelle) has a 1/32" needle. Does labelle make something with a needle just slightly smaller?
