Hornby Railroad Class 31 - trailing bogie wheel polarity

I am reassembling one of these locos after minor surgery to the bogie frame and I am hoping someone could advise me which way round to replace the wheelsets in the trailing bogie. The axles appear to be insulated at one end - there is a black bush/washer where the axles meet the wheel. On the other end of the axle is a silver bush where it meets the wheel. Which end of the axle goes to each pickup (+\-) please!?!

The black bush is the insulated side, to the axle will be live to the silver bushed wheel.  as long as the wheels on the trailing bogie are set to the same side, and opposite from the power bogie set up, then just make sure the wiring from both bogies match at the connection point on the motor/DCC socket

Thanks JiLo, very useful. So to put it simply the live feed side of the bogie gets the non-insulated axle.

Yep, thats it!
