Yeap!
I had to drive the axle out of the wheel and rotate the axle bushings so that all sets have the insulated side against the gears.
I supported the wheel inside of a large crescent wrench and tighten the jaws down snug against the plastic insulator. I supported the wrench and using a drift pin, I pushed the axles out of the wheels. After rotating the bushings, I simply laid the wheel on the flat bench and drove the axle back in until the width was perfect. 1.115 or so I believe? I measured something like 1.110 up to 1.118 I think from memory.
For anyone else who converts these, please look closely at each model's axles first. I did not need to do this on any of my other 4 axle diesels.
I should probably look up NMRA specs for axle widths but all my MTH engines run well on my track and switches so far.
