Hi everyone,
I have a brand new DEX210 gearbox here
(note: this is a gearbox from the very first batch of DEX210s) and I'm having a small issue with it. In RM3 setup the gearbox doesn't run freely after I have tightened the motor plate on there. Without the motor plate it is free.
I don't tighten it like I'm the Hulk, actually it's tightened in a very subtle manner. The gearbox was shimmed as per suggestion by the manual. The diff gear does seem free as it can still slightly move from left to right.
I tried removing a 0.5mm idler gear shim: it doesn't help. It means there is something going on with the slipper shaft/mainshaft. I've just tightened the lot minus the bearing that goes in the add-on gearbox piece between the motor plate and housing and it moves freely. So... it seems the layshaft spacer might be slightly too long?
Has anyone come across the same problem? And what should I do? Shim the add-on gearbox piece until there is no more excessive friction, vile some material off the spacer, get a replacement/uprated spacer and/or contact Durango about the issue?
