I started tearing down the 336 last night and I gathered a little list of questions pertaining to the Northern.
P.S. I cleaned the body and it looks absolutely amazing!
- What is the finish on the handrails? I don't know if mine are tarnished/corroded but the finish is very rough and a dull gun metal color.
- What's the deal with the brush springs? Both the brush springs were a combination of two springs intertwined. The brushes did measure 5/16" so yes, they need replacing. However, is the double spring a band-aide for the worn brushes of is that a large motor thing?
- I am not familiar with how the whistle operates. Is it triggered when the reverse unit is in the neural position?
