Does fitting the USA motor block alter the height of the trolley ?
That depends how you do it..Does fitting the USA motor block alter the height of the trolley ?

If you 'just plonk the body on top', then yes, a little (higher, from memory)..
But not difficult to get it acceptable. - Even I have done it once. Must have turned-out OK, as I was offered good money for it. - A Christmas version, with a festoon of coloured lights, and a 'bargain' LGB Christmas music sound box.
I was going to do a second one, but then found that Bachmann Europe had the motors available at that time, so it never happened..
Dan was asking.. And I was saying..There is something wrong somewhere as you should not see the axles.
So it would be a 'better' solution to drill the frames, and fit bearings. - Rather than trim the axles.the weight of the loco is transmitted through the chassis, to the sideframes, and from the bearings in the sideframes to the tips of the axle, the motor block sort of floats freely.
I take your point Greg but the Bachmann tram is so light there should be no problem. I have had these modified trams running at shows continuously all day without problems. I would not even bother to use a Bachmann tram with its original equipment as they are not reliable enough for shows.A word of advice, the USAT motor blocks are not designed to take the weight of the train through the motor block.

This is even more important to respect in the case of the NW-2 motor blocks, as most USAT axles have a brass bushing/bearing on the axle to the motor block, but I'm pretty sure the NW-2 axles ride directly in the plastic motor block, no bearings to speak of.
Clearly being a trolley, much less weight and most certainly not pulling a train, but keep those locations lubricated on a regular basis.
