Pittman 8514 and MTH PS2

I would say I don't see why there would be a problem only issue is getting wires soldered correctly so it does not start in reverse otherwise no problem just solder white and yellow harness to Pittman motor and your good to go!

No sweat at all driving a Pittman motor with PS/2, tons of MTH steamers do that without any difficulty.

I am worried about voltage and amperage on the motor. 

Not a problem, the Pittman is handled just like any other motor in PS/2 locomotives. 

Thanks guys.

I'll post what I have done, in hope you all will tell me how to do it better

As others say, no problem from voltage/amperage perspective.  I'd think mounting the tach board and printing a tach sticker/tape will be a bigger chore? 

There is a tach mount for the Pittman motor that comes with the upgrade kit, I'm sure most of us that do upgrades have a few of them laying around.   As long as the flywheel is a standard diameter, the tape images in the pinned documentation thread should do the trick, print them on half-page gummed shipping labels.

Thinking I'll attempt to fabircate my own.  What is the distance for the tach tape to the reader?

It wants to be about 1mm from the tape, and if you're going to err, do it on the side of slightly closer, the sensor peaks at around .75mm, but is close from around .6 through 1mm.  I fabricate a lot of "custom" holders with Styrene, many of the locomotives I do don't have standard motors and mounts that will fit the MTH holder.

Something I have noted about the MTH PS2 board and what they will drive is, the outputs don't get unusually hot till the static resistance of the motor / motors it is driving drops below 1.75 ohms.  What I have not tried is driving a coreless motor with a PS2 board as they are very fussy about the PWM frequency.  I tried driving a Maxon coreless with a Lionel DCDR and both the motor and the output triacs got hot fast.          j
