Class 25/33: Step 13 – Bogie Fitting

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

  • Take a bogie and seat the top of the gear tower into place at the bottom of the chassis, butting it up against the base plate. The large gear (25 tooth) at the top of the gear tower should mesh with the worm gear. The vertical brass pick up on the bogie should brush the copper strip on the underside of the base plate – make sure it doesn’t get caught when slotting the bogie into place, as this is a common occurrence.  If it does get caught then pull out the bogie and try again, perhaps using a small flathead screwdriver to guide the vertical pick-up as you seat the bogie. Next slide the metal bogie retaining block onto the chassis. This is where it is important to have the nuts on the chassis in the recesses flush with the chassis sides, since if they aren’t then you will not be able to slide the bogie retaining block onto the chassis.
  • Screw the metal bogie retaining block into place, as per picture 2.
  • Picture 3 shows how the pick-up should brush the bottom of the base plate on the copper strip.
