Class 25/33: Step 5 – Bogie Disassembly

«««« Back to Previous Step     ♦     Service Guide    ♦     Forward to Next Step »»»»

  • You should now have your locomotive disassembled into the components shown. (Note the brass brush holders are not shown, which are best left seated in the chassis on this model, since removing them can damage their clips).
  • To disassemble the bogies, first remove the side frames. The side frames clip onto the bogie chassis at the back (opposite end to the couplings). Apply pressure with a flat head screwdriver, as shown in picture 2. When you remove this you expose the coupling and spring – be ready for the spring to try to escape. One method is to undertake this step in a clear plastic bag, or to place your hand over the spring and coupling when you disassemble the bogies so that the spring does not fly away. If the spring and coupling stay in position, dislodge them anyway, since they will dash for freedom otherwise and most likely you will not find the spring again. The wheels then unclip from their slots (pull them downwards away from the bogie chassis, being careful not to damage the copper pick ups behind the wheels).
  • The copper pick ups might detach easily. If they do not then slide a cocktail stick behind them and tease them off as in picture 3. If you are careful, teasing them off by sliding a modelling knife blade behind them can be very effective. However, this should be done with caution, and certainly not advised for children. Do not remove the gears from the gear towers (unless you have split gears) as these can be damaged and you could split the gear tower when re-inserting the stub axles.

Note: For beginners it makes it easier if you keep each bogie and its pick-ups separate from the other. This makes identifying which pick-ups belong to which bogie chassis easier. The small “L” shaped, or hockey-stick, pick-ups are not the same on both bogies. Perhaps put each bogie chassis and its pick-ups in a small plastic bag and label them “Bogie 1” and “Bogie 2”.
