Pandora Posted November 10, 2019 Author Share Posted November 10, 2019 (edited) The Railroad R3757 / R3758 ex-Lima class 47 models Prince William and Prince Henry are new in stock , the catalogue describes their motor as a 5-pole skew wound type. I cannot find a service sheet to answer my question. ( FoundHornby Service Sheet it is 309 ) How are the models powered? Have Hornby fitted a central motor and cardan shaft arrangement? Or have Hornby substituted a 5 -pole armature into the typical Lima pancake style of motor bogie Edited November 11, 2019 by Pandora Link to comment Share on other sites More sharing options...
giz Posted November 10, 2019 Share Posted November 10, 2019 (edited) The Railroad TTS sound class 47 I have has the standard Limby motor bogie, as fitted to the ex-Lima 31, with a can motor mounted within one bogie driving two axles. This is similar to all the ex-Lima locos so I would assume this new release is the same. None of the Hornby released ex-Lima models have had pancake motors. This is the type: https://www.petersspares.com/Hornby-x9769-class-47-drive-unit-complete.ir Edited November 10, 2019 by giz Link to spare part added 1 1 Link to comment Share on other sites More sharing options...
Pandora Posted November 11, 2019 Author Share Posted November 11, 2019 (edited) I have purchased a " Prince" the running with the non-pancake drive is is very smooth, I will swap the chassis under a Lima D1733, thank you for the information in your post Edited November 11, 2019 by Pandora Link to comment Share on other sites More sharing options...
Pandora Posted November 12, 2019 Author Share Posted November 12, 2019 (edited) I have commenced the chassis swap, upgrading the running qualities an old Lima D1733 (pancake motor drive chassis) to the latest Hornby DCC 5-pole skew-wound motor chassis from the Prince, other than a single detail, the Hornby chassis assembly is a direct replacement being fully compatible with the Lima D1733 body, the single detail is the main bodysides glazing unit, the solutions are either for the Hornby glazing unit to be 1 ) unclipped from the Hornby Prince body and fitted to the Lima D1733 ie following the chassis, or 2) the near-identical Lima glazing unit trimmed to give clearance to the wider Hornby motor bogie.
