DEX210 Slipper or Diff Problem

[Axeboy]

Hi Guys

Been slowly building my DEX210 kit and its almost done but has a bit of a problem.

Basically the power from the motor is making it to the spur ok, but almost nothing in the wheels. Well, when I say nothing, they will turn off the ground but on the level it sits almost on the spot, maybe moving a touch.

The slipper seems fine but I can only assume its the ball diff. I followed the guide on building it as well.

Any advice on the tightness of the ball diff screw? And also, the tightness of the slipper in-case I'm doing anything here too?

I had quite a few issues with my kit too where the gearbox was binding in a couple of places.

1) Check the 3 long screws that go through the gearbox around the lay shaft spacer and bolt the motor plate down are not hitting the slipper disc. If tightened too far or not correctly installed with washers or orientated they can touch the disc and result in the whole thing binding up. In my case all 3 screws were protruding too far.

2) Check the Layshaft spacer. Mine had to be machined down a fraction as when the gearbox was tightened it would bind up again. Machining it down solved this issue.

I would remove the motor and check the gearbox by turning it by hand which should be easy. You can remove one thing at a time, Layshaft spacer, differential, gears to check what the issue is. It's a tedious job but you'll work it out I'm sure.
As I mentioned I had several quality control issues with my kit which were addressed by Durango with new parts. If you need me to talk you through anything just PM me. Good luck

Thanks for that.

I managed to tighten the diff a little better using a better driver and its working "ok".

It doesn't sound right to me though so I think I'm gonna strip it down and again both diff and box to see if it helps. I checked the build throughout and did turn it by hand, but I must have missed something or a screw might be touching as you have said.

On another note, is the RM3 setup reverse rotation on the motor?

Thanks for the help matey

No worries. This should answer your motor rotation question: (yes, Rm3 rotates backwards)

Appreciate the help

Seems to all be in good order now. Not had a real chance to test but it sounds sweeter (found a few screws protruding).

Thanks again

I still think I need to rebuild the diff. Turning one back wheel by hand is making the other wheel turn the same way, so I think I've over tightened it.

When it was loose though, the drive issues were happening.

I think i'll plan a strip down at the weekend
