Bachmann Class 150 Pickup Problems Solved - Part 2
Continuing on from fixing the Silverlink class 150/1 Sprinter, I have now repeated the steps with my Provincial sector class 150/1, with photos!
Dismantling is relatively easy, once the three body fixing screws are removed from the chassis. Two very small screws hold the PCB in place, and two larger screws retain the bogies. A flat-bladed screwdriver at the inner ends of the bogie side frame mouldings will release those (easier to do before removing the bogie retaining screws), and the axles just pull out with a small amount of force.
This is what you should have before any soldering occurs:
Insulated wires are prepared by tinning the ends, and the copper pickup strips on the bogies are also prepared with blobs of solder - one up near the step, another just above the "tee" formed with the strip along the bogie sides. The wires are soldered at one end to the strip. Meanwhile, some brass (or copper or phosphor-bronze) pickup wires are prepared by cutting to length (a little shorter than the bogie wheelbase) and the centres are tinned with solder.
The pickup wires need to be bent outwards and slightly downwards to bear on the wheel backs when the axles are reinserted later.
The insulated wires are fed up through the slots in the chassis block. The wires can then be soldered to the springy strips that bear on the tops of the bogie strips.
Reassembly is mostly the reverse of dismantling, although I found it better to screw the bogies back on as soon as I had soldered the wires to the PCB. Axles and sideframes were clipped back into place, ensuring that the wires go behind the wheels. From outside, one would never know there was anything different!
After a quick test, the body is replaced and the unit is ready for service, with no more hesitations or flickering lights. I'm not too sure whether the Provincial liveried units would ever have run in multiple with Silverlink ones, but here are the two units posed together, regardless!
