Well, see the ongoing discussions about replacing the small motor in the Hogwart's locomotive, that might be it's salvation.

Allegheny, if you use the train with the 3 coaches in the set, the original motor will be OK and enough strong. No problem.
I agree with Isaac- that Harry Potter set will probably last several years pulling 3 or 4 cars . If you eventually have to replace the motor no big deal. I would buy it- make the boy happy!

Gentlemen,
Thank you for your advise as I really wanted to get this set for him.
I'll consider the motor replacement.
The issue is I just don't have that kind of free time until I put an end to all of my charitable activities as I'm still working fulltime.
If the upgrade were a simple drop in - no problem, but it seems you need to build an appropriate shim. Not sure if a metal one is really needed vs. a plastic one which can be made a lot simpler.
The removal of the worm gear and its replacement - isn't clear to me. Is it pressed on and can it be removed from one motor to the next without breakage and bending issues of the motor shaft and worm gear?
The motor and worm gear are both purchased separately, you don't use anything from the original motor. The worm is just pressed on, that could be a challenge if you don't have the proper tools. The shim is the sticking point I suspect.

Thank you John for your reply as it clears the matter up considerably.
@Isaak570 posted:Hi everybody, I succeeded to change the original motor, with a mabuchi RK 270. It's necessary to add steel plate because the distance between the holes is not the same. Just a buy a worm module 0.5, and turn a big flywheel, the power is now ok.
that adapter plate looks great, but why the odd shape to the flywheel you mounted?

While the gear is technically an interference fit, its less than .001 smaller than the motor shaft assuming is an actual 2mm. A bit of heat and the gear should just slide on.
Good to know about those 370 Mabuchis. Likely ideal for this project not only for overall size but small shaft diameter given how small the gear is.

Yep, I didn't realize there was an intermediate sized motor that would work, so it is indeed good to know. Now, I just need to figure out how to get a couple of those plate machined...
Heat was in my plans when I press the gear on.

It must be for gyroscope harmonics,….😛😛😛….BTW John, your Jinty bushings are in your mailbox,…

As long as you don't have any grades.

Not for you John,…the other John,…something he’s been waiting on from me for a minute,….😉

The PE comes in a Series II version that's the same size, but has a full size motor. Mine pulls eight (and probably more) cars easily. I upgraded it to cruise, RS5, fan driven smoke, a Super-Chuffer, and LED lighting all around, including class lights, cab light, tender markers and reverse light. So, for the right price, (you don't want to know), you can have the PE with all the stuff you mention.
Well I will need to know as you are working on my Daughters P.E. loco.
Judging by your comment, I better brace for impact!
It's fun reading this thread, can't wait to see the final solution on the Hogwarts Loco. I have a P.E. set from 2007 and the Berkshire (upgraded ERR TMCC) was fine with the set of passenger cars that it came with it, but I added a few more coaches, and now I have 8 coaches plus a Candy Cane flat car. The original Berkshire that came with the set was struggling pulling the whole consist of 9 rail cars. Then I upgraded all the P.E. passenger cars to LED anti flicker lights and added 2 ounces of weight to each coach so they would ride more realistically. Well that did it, the original P.E. Berkshire would come to a crawl with any size grade, and it would slow down significantly in the turns. I was considering a motor upgrade, but the poor old Berkshire was showing it's age so I cheated. In 2019 the LionChief Plus 2.0 P.E. Berkshire was introduced, so I bought one. The LionChief Plus 2.0 pulls my full P.E. consist and everything else I put behind it and maintains speed even up hill, so far! I haven't lifted the body off of the LionChief Berkshire, haven't had the need, but if anybody wants to know what motor it has in it let me know and I'll pop the top off. I tried to look it up in the Lionel support page and they only list one part, and it's not the motor.

Hello, yes the new flywheel I have turned is not very beautiful, because it comes from remains of brass that I have found on basket on my work...
I have just turn the diameter and the longer to fit on the locomotive.

I'm virtually 100% certain that all the later set PE models have the Series II larger motor.
Please note for the hole 3mm you need to drill just a little large to receive the head of countersunk screw.
It depends of the diameter of the head of your countersunk screw. For me it is 5,5mm. The head of the countersunk must not flush from the adapter plate.
