Niles Project ~ Motorin'

Installing a Hollywood Foundry Half Floor Motor Mount and Level Shifting Gearbox on Niles #107.


Right out of the box the mechanism is a pretty good fit. This is going to work just fine.

The immediate problem that presents itself is that the mounting holes don't line up with anything to screw into. The second problem (that I wish I had taken a picture of) is that the gearbox is too low. The drive shaft to the truck is on an angle. And while that would still probably work, it seems to me a level drive shaft would be the most efficient and problem free.

Both issues are easily remedied in one fell swoop by soldering a length of 1/16" x 1/4" brass bar stock to the frame.

Fortunately I have the good folks at the Southern California Traction Club (and their drill press) to help me drill and tap the holes for the screws. The motor also came with a silicone mounting pad to absorb the noise. I cut it to size and placed it between the new brass bar and the half floor mount as seen in the photo above.

Between the new brass mounting pads and the silicone pads, they lifted the motor to just the right position for the drive shaft to the new LowBoy Trucks to be perfectly level. And the motor is still below window level. All thats left now is to transfer the sideframes from the old truck to the new truck and wire the motor to the decoder. Then this car will be ready for a spin around the test track. Yes sir! All ready for a spin around the test track!
