'46 Odometer Repair

[51woodie]

The odometer in my '46 Super Deluxe quit at 859999. I decided with Covid, shipping and customs costs to Canada, I'd take a shot at it myself. After disassembly I confirmed that the reels on the odometer were jammed, and caused one of the drive gears that transitions from outside to inside the frame to spin on the shaft. That was an easy fix. I cleaned the end of the shaft and the gear hub then soldered them together. The problem with the odometer seems to be that the 4th 5th and 6th reels are progressively stiffer, so when the odometer rolled to 9999, the accumulated resistance overstressed the drive gear train. I have looked at how to disassemble the reels to clean and lube, but I can figure out how they come apart. Anyone have any experience with this process?
