hayfield Posted November 28, 2015 Share Posted November 28, 2015 This large pitman motor arrived with several other items in a mixed lot, think its for a 0 or larger gauge loco As you can see the body of the motor about 57 mm long, 24 mm tall and 21 mm wide. The shaft is 3.16 mm diameter (1/8th") and has 12 volts on it. Pitman USA stamper on it Any ideas please Link to post Share on other sites More sharing options...
Horsetan Posted November 28, 2015 Share Posted November 28, 2015 Here's some of the motors produced by Pittman Funny, I have two in the drawer - both DC195s. They run alright, but are not really for "small" engines. More info here Link to post Share on other sites More sharing options...
hayfield Posted November 29, 2015 Author Share Posted November 29, 2015 Horestan Thank you, are they for 0 gauge as I think I would struggle to get this one in one of my Wills Flatirons which must have one of the biggest tank spaces in 4 mm scale. Looked at my Roxey Beattie Well Tank and perhaps would struggle to get it in that And what about the shaft size for gears. I take it's a DC195s then Link to post Share on other sites More sharing options...
Horsetan Posted December 1, 2015 Share Posted December 1, 2015 The DC195 will fit a big (in the sense of available space) 4mm model. It's about equivalent to the XO3/4. You could just about cram it into a 03/04 shunter, under the bonnet. The shaft diameter is 2mm at least, and might even be 3/32" - I will check my samples.

Horsetan May not be a DC195, look at the photo The Pitman has a body size (not including the shaft) of 59 mm x 24 mm x 20 mm X04 41 mm x 17 mm x 12 mm The magnet alone has about 6 times the mass, it is really big against the X04 Link to post Share on other sites More sharing options...
Horsetan Posted December 1, 2015 Share Posted December 1, 2015 Yours is not a DC195. These are DC195s: ...and the shaft diameter on my pair seem to be 3/32". Your "O" gauge sample I am still trying to identify. I think it is a DC77A. The only other thing it could be is a DC81. Link to post Share on other sites More sharing options...

Horsetan Posted December 2, 2015 Share Posted December 2, 2015 Horsetan Thanks for all the effort It's been like a trip into the past. As I understand it, Pittman motors came to prominence in the 1960s via the slot-car racing hobby, and weren't originally meant for model locomotives at all, but Pittman were very quick to realise the opportunity for expansion. For 4mm scale, the DC195/DC195A seems to have been the smallest motor that they produced at the time, and was a bit more sophisticated than the XO3/4. The late Guy Williams used one in a scratchbuilt "King", and this endured until the RG4 came along. Link to post Share on other sites More sharing options...
