I did a teardown of my oldest RI&P Generals today. Dissesmbled, brushed flushed, & wiped everything.
I have little driver cupping starting on one driver and found some roller bracket plastic flashing had been causing the front roller to partially hang in the up position by the roller axle stub. I removed the flashing and it swings smooth now after 40 years.
The rear roller has a groove started from more pressure, and lots of Super O time (and likely compounded by the engines heavier draw at the better connection). I'll just swap it with a car's for now.
It was good therapy though as "my hot rod's motor blew"-
It pooted forth a cloudy stream of putrid magic smoke 6ft long, obscuring the the tender and cars beneath the dimming, pulsing street lamps lining the ceilings edge before creaping to it's last stop ever, where it promptly delivered the final insult of leaving me sitting alone in silence, in a now stinky and pitch black room as the breaker tripped; clack.
The teardown of that revealed I had yet another dual winding motor's field coil short out. This post war 249 was the first upright motor's coil to give up the ghost since the 70s for me, but "it is always the field"
