Need Railking sw1500 parts diagram

Forget smoke. No room.

What doesn't fit?

The shell won't go down all the way because it's hitting the flywheel on the front motor.........................

How is that a problem with the electronics?

Well, if the shell won't clear the motor, then the electronics are useless. I took the motors and electronics out of a larger diesel, and I think I can get everything else to clear. But the problem with the flywheel on the front motor rubbing the inside of the hood is enough to cause major problems. It would need 1/8 to 3/16 of an inch for the shell to sit down all the way so I could put the screws in it.....................................

OK, but this isn't an electronics issue.  If you specified a motor fit issue in the first place, we'd be farther along.

One solution is to find the correct sized motor and all will be well. You can almost surely order one from MTH parts.

If the tach is on the rear motor, you could remove the flywheel from the front motor and cut down the shaft.  You could also find a different thinner flywheel for the front motor and just cut the shaft down.

Have you tried running the engine yet? If you are using motors that were for another engine, the chances that the worm gear is not correct for that engine and will bind. If it runs smooth with the shell off, you got very lucky. Call Midge at MTH and tell her you need a motor for a SW1500. Much thinner flywheel.

I haven't run it yet, but both motors turn free {by hand}, and the wheels all turn, so I must be ok there. The motor that's rubbing the hood has a much thinner flywheel than the other motor, but the other motor is in the cab and has more clearance. This engine was originally powered.

Like I said and then Chuck said, get the right motor.

The front motor has the striped flywheel, and it's the one that's rubbing. It also has a much thinner flywheel than the rear motor.  Just from what little knowledge that I have from looking at different parts diagrams, I can't seem to find a thin flywheel motor other than the one I'm trying to use. That's the reason I was looking for the above mentioned parts diagram. The motor I have seems to be the right one.......

MTH no longer provides parts diagrams in the their locator, however, they combined them into downloadable files here.  Your switcher is not included unfortunately.  You would need to contact MTH for a parts listing for your specific engine.

Thanks everybody for the replies. I guess I'll have to call mth.

John:   QUESTION:  Is it ok if I send you an email, using the 'gmail' address in your profile ??
((People tell me this is the best way to contact you--reply to one of your posts, then ask permission to email you.))

Reason For Asking:  I am trying to order an MTH Railking SW1500 (or similar 12" long O ga. MTH switcher) via Bill Henning.  I would like to know if you can:
(1) add the DCC/DCS switch that MTH used to include (so I can  run engine on DCC), and
(2) add a flashing strobe light on top of the cab roof.  I believe Bill said that you have done both of these things in the past.   Thanks.  - Jim Ingram

Sure, send me an email.  Of course, it would have been easier if you had an email in your profile.

If you have the right motor, it wouldn't be rubbing on the top of the cab, so it's a bit hard to believe something's not amiss there.

Is the board you have capable of DCC?

I have the 30-2215 UP SW1500 complete less a bad 5V Board also.  I can sell this if you want it as motors and all the harness for the set up.  You just need to add the 5V connectors to your 3V board.  And change the speaker to a 4 ohm for proper sound level.  I can send a speaker too if you do not have one.  E-mail in profile.  Or if you just want the motors can do that too.  G
