    Pittman replacement

    It looks rather empty here...

    I didn't want to head over to the Diesel shop for this question....but,

    Does anyone know if there is a close relative of a Pittman DC-70 that is a can motor? I went around on Gaggle yesterday for a good hour looking for either a reference chart or 'real' information on an available substitute motor that comes close to speed, torque, and size for that old Pittman.

    Jim,

    Can't help you out with the exact info on this can motor. I have to do some digging and find the info on it. I got it off of E-bay. It's going into a Hobbytown PA Alco. The original came with a DC70 motor. Upper left corner.



    And this is the replacement can motor. It's either a 7 pole or 9 pole motor. The conversion idea came for a modeler on the Model Railroader forum. He converted a Hobbytown PA Alco using this motor.



    Might be enough info on the motor to find it on E-bay.

      Bernd,

      I can't get enough info off of the photo (glare) to search eBay. It looks very well built.

        Jim, from Bernd's picture, motor #23DT2R I was able to get this website, but couldn't find this particular motor shown here; http://www.portescap.com/

          Thanks Louis,

          I was only able to see 'scap' and '23D12R', not enough for Google.

          Thanks, I've also sent NWSL a message looking to see if they had one that would match up to the DC-70 power.

          We'll see.

            Jim,

            found the guy that I got the motor from on E-bay. He may not have that same motor at present but looks like there are some close to the same size.

              Terrific! That is the trouble I have with eBay (actually it's me) recalling some guy you have bought something from before. I'll check these out, looks like a good source.

              Thanks!!!

                You're welcome Jim. I usually mark "follow seller" so I can find there products that I think I might need more of eventually.

                  Jim:

                  My suggestion is you think in terms of an entire remotor/regear package for something which has an open frame motor. If so I'd begin with the Northwest Short line site ( www.NWSL.com ). If you aren't familiar with them they are the best single source for what you want to do. They have tutorials on the website as well as phone consultations with actual live English speakers to help you sort out what you need for the project.

                  Rule of thumb is: Buy the largest can motor which will comfortably fit your space.

                  Final thought, the wheelsets in your photo look to be brass, if so you will want to junk those as well and go with nickel-silver.

                  Let us know how things go.

                    Ah, those are my wheel sets not Jim's. I won't need to buy nickel silver ones because I'll cold nickel plate the brass wheel sets.

                      K, sorry for the misread. I've no experience of DIY plating. I send any plating work to a professional...toxics worry me.

                        That's OK. It happens.

                        Nothing much toxic with this kit. http://www.caswellplating.com/electr...ting-kits.html

                        You probably breath more toxins driving to work from the vehicle in front of you than you'd breath from this process. Just saying.

                          I might be able to make a suggestion but I need a bit of information. What are the dimensions of that motor you are attempting to replace. Top to bottom, width of the motor, overall length of the motor and shaft, length of the motor shaft itself, dia of the motor shaft, distance from the bottom of the motor to the centerline of the motor shaft. As for torque etc. That varied with the number of windings. Over the years that motor was issued in numerous configurations. All of them were voltage hogs that required a relatively high amperage. New can motors use a lot less voltage and amperage. Once you have the dimensions I might be able to recommend a can motor to use as a replacement.

                            Thanks Denny,

                            I ended up with an excellent motor from micro-loco-motion.com. Eldon is a model railroader and extremely knowledgeable on small motors. I put a 5 pole, ball bearing, double shaft, 20X40mm Neodymium motor in that engine. WOW! It runs great!
