Along the way, a beautifully painted & detailed Athearn BB shell was acquired for my collection.
Someone did a really good job detailing this unit fit a features.
My task was to find a suitable set of parts to make a great power engine with this shell:
- A frame was taken from a junk engine that was in a batch of other HO junk stuff on eBay.
- The trucks were made up from a dummy truck pair.
- The truck gears were from my parts set
- The wheel sets are the Athearn 42 in NS upgrade versions.
- The standard BB drive shaft & tower gears were out of my parts set.
- the electrical connections were based on the modified five wire post.
- The motor selected was from the Chinese Hi-Torque motors described in the 2020 Motor DOE test series.
- The unit was tested on DC with no electrical module, on fixed DC(Rail Pro) & on DCC (NCE DASR card mobile decoder).
- Three ounces of weight was added to maximize the performance.
Motor Specs:
5 pole machine 12V Rotating speed：9100 rpm
The results were a very good performing engine the runs very quietly for a basic BB unit. The test results will be added to this post in the near future , check back again.
