Sharp RT-3151 Cogwheel Repair

The Sharp RT-3151 uses a very small cogwheel that provides the drive for the rewind function. Unfortunately on my unit, this cogwheel had crumbled due to old age and stresses placed upon it over the years. Luckily, I was able to find a replacement cogwheel that had been recycled from an old printer.

After replacing the cogwheel, it was as good as new, and in many ways better. The small white cogwheel usually engages with the black cogwheel during the tape rewind operation.
