    Thank you! I needed to see how to reassemble my IHC Pacific after a repair. Slowing down your video helped me out.

    I've got quite a few of these Pacifics and also Mikados; some RSO - Yugoslavia and some Mehano - Slovenia depending on their age. I've done a lot of cosmetic work on the shells and little on the mechanisms. They're really easy to take apart but a booger to reassemble. Thanks for the great video showing how reasonably simple it is to replace the motor if need be and of course if you can find a suitable replacement.

    I bought one (Rock Island) with a similar motor issue from my local hobby store, and it was traced to the commutator not being cleaned. It still runs to this day with the original motor

    I've got two of the Mehano Mikado's. One is the famous #4501 Southern Crescent and the other is an L&N Mikado. Both are smokers and I changed out the incandescent lighting to LED lighting. I've got several Mantua Pacifice (4-6-2) which I changed all the magnets in the open frame (Pittman) motors to rare earth magnets. It made a HUGE difference in current draw and now they will "creep" around the tracks. Cheers from eastern TN

    I fixed two of those for my uncle recently. The brushes and springs fail and let out the magic smoke. I put in a new can motor from ebay. Not bad engines but motors are 50/50 failure rate

    I wish the reassembly part was not sped up. Do you have a video of reassembly at regular speed so I can see the process?
    Thanks 9:54

      I don't unfortunately, but I do have another one of these videos coming up soon that I hope will help. My apologies--I'm learning what does and doesn't help people as I go, so I'll remember this for the future.

    I literally got the same model as you and it’s having the same problems, what’s a good replacement motor for it?

    I got this same model 4-6-2 #2904. IN mid 1990's the motor was burned out only after a month or two. I replaced it with a 5-pole can motor and it is as noisy as ever. I can't seem to quiet it down. Now it sounds like the motor shaft and gear is slipping. I don't know what to do.

    • @DoctorHobby
      @DoctorHobby  Рік тому +2

      You can actually use a specific adhesive to re-attach the worm gear to the shaft if you're sure that's what's going on

      @@DoctorHobby I actually used super glue to reattach the motor's flywheel to the shaft. That seem to have been the issue. As for the noise, it has quiet down a bit after some running time and oiling. I made a video for Father's Day Special and installed a LED light. Runs better.

    The thing about IHC models is that before anyone wants to put a decoder in them, make sure you do a motor stall test first to make sure it does not pull more than a certain number of AMPs. Last time, my local club tested out an IHC Premier 2-10-2 and it pulled 3A during a stall, which out club had to sell off since they did not want to do a motor replacement job. The reason why you want to test how much a motor is pulling in AMPs, is because most decoders are between 1-2A. Exceeding beyond that window will burn your decoder if a short happens, especially through the motor. Very important to consider!

    Yea. a three pole motor, I believe.I have a couple of my dads & really need a motor upgrade in them as they dont run at slow speeds.

      @nathanchan4653 2 роки тому

      Fun fact:
      This pacific locomotive was originally a Lifelike tooling in the 1970s before AHM acquired the tooling and then IHC took over the tooling before the locomotive was discontinued in 2005 or 2007 (?)

      I generally take them out if they're the older kind.. otherwise I don't mess with them directly unless I really have to. There is a video coming up of me messing with one, however..
