Ruote classe 31 P4 / scartamento 18,83 mm

I have used these before and they are excellent. I was told they would be very difficult to fit and would involve virtually dismantling the bogies. It took me 30 mins and the first 20 were spent trying to work out how to get the keeper plates off! You just need to be brave when flexing the bogie frames to pop the wheels in but they will go in.

Got the wheels just the loco now

Product works well once fitted but involves almost complete deconstruction of the loco, including desoldering power from the main circuitboard. It also involved considerable removal of plastic from the bogies to prevent the wheels rubbing. This is not a straightforward fit, but they are a good quality wheelset.

Pre ordered before Christmas. Arrived recently. Very nice wheels but different to the 37 and Deltic utilising outside bearings which require a little more effort to fit.
