TSDZ2 Blue Gear Replacement and Service

A detailed step by step video if you need help to replace your blue gear or perform a service on your TSDZ2 motor. So far my motor has done 2500km and it seems to be fine except for some slipping under very high loads. The Blue gear was replaced at 1380km and the brass gear is holding up well. It looks as though there is one bearing that has worn which should be a relatively easy fix. Let me know if you have any questions. Sorry that this video is so long and drawn out please fast forward through it to the bit you need.
