Lubricating the Gear Box on a Sunset N&W M, 4-8-0

Hi All,

I want to lube the gearbox on the above engine.  Is it as simple as removing the gearbox cover and cleaning out the old and putting in the new lube?

One would think so. I've many of them on my Sunset/3rd Rail steam locomotive models.

I ask this because I lubed the Sunset PRR H-6, 2-8-0, and when I removed the gear box cover, the motor fell into the boiler (it was upside-down) and it was an awful job getting things right again.

Although I did mine "up-side-down" in the cradle, only took one screw all the way out, and then loosened the second screw SLIGHTLY, in order to access the hear. All I did was add a VERY small amount of Lucas "Red-N-Tacky" synthetic grease.

Thanks.
