Tigg Posted June 5, 2016 Share Posted June 5, 2016 Hi All,I'm currently repairing R214 (Castle Donnington Power Station 0-4-0 shunter). The propshaft won't connect to the drive cog and the motor isn't wired to the pick-ups.Re the cogs, ideas went from getting a bigger drive cog that will reach to the proshaft cog - but that will mean having to remove the wheels/axles to fit it - to adjusting the motor mounting, but since the rear drive wheel axle seems to run through the mounting, that idea didn't seem practical. Re the lack of wiring, should the wires be soldered directly to the pick-ups? If so, which wires go to which pick-ups? Any guidence in this would be most appriciated.P.S. Are there any tools available to remove the coupling rods/crank pins and the driving wheels?Thanks. Link to comment Share on other sites More sharing options...
Chrissaf Posted June 6, 2016 Share Posted June 6, 2016 P.S. Are there any tools available to remove the coupling rods/crank pins and the driving wheels?.I'm not familiar with this particular model, but if the coupling rods are held on by Hornby Hex headed micro bolts, then they are likely to be 12BA. A 12BA (2.5mm) Nut Spinner can be purchased from Expo tools. Link to comment Share on other sites More sharing options...

Chrissaf Posted June 6, 2016 Share Posted June 6, 2016 I wouldn't like to say ya or nay, but I think that the round coupling rod fixings are maybe not bolts but press fit securing pins. Your model may be one of these Hornby Service Sheets. None of the 0-4-0 loco chassis sheets below specifically mention your R214 model number, but they all show predominantly the same round pin coupling fixing pin arrangement. I included the 200 series sheets for completeness of information, but I think that those are dated probably too recently (1997 - 2008) for your model R number..HSS082HSS082AHSS115HSS115AHSS200HSS200BHSS200CHSS200DHSS200E Link to comment Share on other sites More sharing options...
Chrissaf Posted June 6, 2016 Share Posted June 6, 2016 PS - Just had a closer look at HSS082, the parts list documents the coupling pin as a screw. But the HSS115 documents it as a pin. Take your pick. Link to comment Share on other sites More sharing options...
Fishmanoz Posted June 6, 2016 Share Posted June 6, 2016 Service Sheet number is 115A so you have it covered in your list Chris. I looked it up in the Hornby Guide. And the offending item is designated a pin, not a bolt. Link to comment Share on other sites More sharing options...

Most helpful.So, if they are the pins in question, which it looks like they are, what would be the best/most appropriate tool for removing them from the coupling rod & wheels? Thanks again.

Chrissaf Posted June 8, 2016 Share Posted June 8, 2016 If they are just push fit friction fit, then your finger nails. Link to comment Share on other sites More sharing options...
Ruffnut Thorston Posted June 9, 2016 Share Posted June 9, 2016 Or, if you don't want to break your nails, a fine screwdriver used carefully under the rods close to the pin? 😉 Link to comment Share on other sites More sharing options...
The Doc Posted June 9, 2016 Share Posted June 9, 2016 I've used a slimline pair of pliers in the past - the pins came out fairly easily. Link to comment Share on other sites More sharing options...
