Pat what all is involved in this motor swap? Is it a straight up replacement or are there other modifications involved? Thanks

Rick, it’s literally a bolt in swap on the MTH engines,…..when MTH went shopping for other motor vendors, they kept the same bolt pattern, motor shaft diameter, and length. The three favorite flavors of Pittmans used in most MTH Premier steam are 9432, 9433, & 9434…….length being the only dictator…..for a short period, MTH used SPG motors. Those motors are a carbon copy of the Pittman, complete with splayed segments, which is the hallmark of a low cogging or almost zero cog…..the only slight hiccup in doing a DIY swap would be if the Pittman has a different thread for the mounts, …..but even that’s a simple fix,….
