    Default Re-motoring old bachmann locomotives

    I'm looking to re-motor a couple of old Bachman diesel locomotives. They're both pretty close to 30 years old. Both have lots of run hours and the bushings are starting to squeal.

    Any recommendations for newer (third party) motors that will work or should I just contact bachmann for replacements?

    Thanks in Advance,

    - Gary

    Squealing indicates need for lubrication, not necessarily replacement.

    ... I agree with Doug a drop or four of oil on the motor bearings will fix the squeal.

    to replace the motor, you have to find out what motor you have in there.
    30 years ago b-mann had three motors they could have used.
    the most likely is also the easiest to replace. however. a picture of your motor is the quickest way to know
    what advice to give. most people have a hard time with pressing the joints off the motor,
    and again b-mann did different joints... some are easier than others to replace.

    Apart from legitimate sentimental reasons, why would you want to spend money on rehabbing 30-year-old locomotives, much less anything from Bachmann?

    Seems to me that your hard-earned cash is better invested in some new, quiet and smooth-running Kato, Atlas or Life-Like locomotives.

    Er, certainly (I should have put in a reference to http://http://www.spookshow.net/trainstuff.html)

    In my defense for the faux pas, I'm also listen to the Carolina Hurricane game -- Go Jerks!

    Bingo, that is a major reason.

    Another is that the older I get, the harder it is to get the things apart and back together.

    Third, while these motors work, I'd like to replace them with smoother running, lower starting voltage motors if possible.

    I reckon installing a better motor now will outlast me.

    I have to advise you are not taking an easy path...

    I was hoping that was not one of the motors you would find.

    If you ask Bachmann they will tell you parts are not available for that loco.
    They might also tell you they will replace your loco under the warranty that covered that loco.

    if you want the loco running; clean and oil it.
    if you want smoother or more reliable or quieter, you will be doing some fitting to get your replacement motor in there.
    ... you are not going to get modern Atlas or Kato quiet,reliable, and smooth unless you are VERY lucky.
    (If you get this lucky, you blew your chance to win a large lottery...)

    The most likely motor to meet your needs is a b-mann plus motor from an f-unit.
    this motor is about the closest in all dimensions. the 5 pole b-mann motor is a good motor.
    you may need to do some grinding or filing or adding some paper wedges...also known as fitting.
    The Kato 4 wheel trolley motor will fit... again with some fitting. less grinding and more wedging.

    Your biggest problem is getting the joints off the motor and onto your new motor.
    ever pulled flywheels off a small motor? I do not think it is hard, however, I have been told it can be a struggle.

    your photo is a blast from the past. I think I have seen one of the parts lot with that motor or u-joint...
    I go look a bit....
