Guys, just this arvo I installed a decoder in a Bachmann BR/LNER V2. luckily these are old split frame models that come apart fairly easily except for the small circlip that holds the eccentric in place. These can be a bugger if you've never pulled one off and are hard to get replacements for if you loose one. After I split the frames and removed the motor I cleaned up the frames to remove the huge amount of grease the factory insists on placeing around the gear wheel. Pity they never seem to get any on the worm. I then removed the the contact springs and the foam pads that stop the motor contacts from touching the wrong frame half. I replaced the foam pads with some suitably sized pieces of 20thou plasticard and did the same to the slots where the contact springs sat. These were glued with CA glue. I then relubed the motor bearings and regreased the worm and gear and then soldered on the motor wires from the decoder. I now put the frame halves back together and placed the wheels and motion back in place. I then soldered back on the front and rear truck pickup wires and checked for a short with my multimeter. No shorts so I then soldered on the chassis pickup wires from the decoder to the rear truck pickups. I used some doublesided foam tape to attach the decoder to the top of the motor and rechecked for shorts. The decoder I used was an NCE N12SR with a rating of 1A continuous and 1.5A peak. This decoder is a double sided one that is fairly small measuring 8.6x18x3.2MM. It also features Torque or Load compensation that works rather well. After i got the body back on I programmed the decoder using Decoder Pro and then gave it a test run. Works very well for a silent running decoder. The Torque or load compensation for the high freqency this decoder uses worked very well with the loco just creeping away on speed step one of 128. Alltogether this is one pretty good decoder and suprising as it's not one I would have normally used. I would have a fitted a Lenz Gold Mini but I was out of them and this one was lying in the back of the cupboard. I just wish I could remember what I bought it for in the first place
