28.7) Push in the bearings from the outside until the bearings connect with the axle ends.
28.8) When satisfied that the bearings are (just) against the pinpoint ends fill the bearing hole with
the 2.5mm sprue supplied, or microrod (not supplied) and fix with liquid solvent from the outside and
leave to harden.
28.9) When set, remove spacing card and trim any excess rod flush with axle box face
28.10) Remove the bogie pivot mounting from the casting spue and remove any flash. Test the bogie
pivot bolt is an easy sliding fit in the mounting hole. If tight, open the slightly with a 3.5mm drill to
ensure a smooth swivel movement.
28.11) Drop the bogie pivot mounting into its locating holes in the top of the bogie stretcher plate and,
using only sufficient glue to attach the plates, fit keeper plates over pivot spindles. Ensure pivot
remains free to move until the liquid solvent has evaporated.
You may prefer to use a larger piece of sheet styrene (not supplied) rather than the moulded keeper
plates supplied.
28.12) If desired, fit the brake shoes on the inside of the sideframe. They should be positioned just
off the wheels with the circle detail on the shoe just visible below the bottom of the side frame.
28.13) Fit the bolster detail (see photo: Bogie Sprue Labelled - Cl. 108 model) centrally to the inside
of the sideframe by placing the square beam against the back of the sideframe and butt against the
underside of the bogie stretcher.
While the basic bogie assembly sets, identify and remove the bogie front channel, guard irons, speedo
drive mount and bogie steps from the etched sheet.
28.14) Fold up the bogie channels E3 (plain) & E3a (with slots for guard irons).
28.15) Locate the guard irons (E7) in the channel with the top of the guard iron firmly against the top
of the channel section and passing through the slots and fix in place (these can
be glued in place with superglue, or soldered). See Bogie end channel 1 (Cl. 105
model) for clear view of channel. Note that only the front bogie, i.e. the cab end,
has guard irons fitted.
28.16) Glue the bogie channels to the front and rear of each bogie with the
bottom of the channel level with the bottom of the sideframe (superglue is recommended for this). The
arrangement of these channels should be:
Front bogie (both units): guard irons (front of bogie) and plain channel (rear of bogie).
Rear bogie (both units): plain channels both front and rear of bogie.
See also Bogie end channel in place (Cl. 105 model).
28.17) Fold up the bogie step tread supports and mounting
brackets (E2). See Bogie step and speedo drive (Cl. 105
model).
28.18) Glue the speedo drive mounting (E14) to the front left
axle box. The spike faces right and down when fitted in place.
28.19) Glue the bogie step mountings in place. The front mounting is in line with the front spring
hanger and the bottom step tread should be (approximately) level with the large spring mounting
bobbin. Ensure the step is kept parallel to the side frame and attach the rear mounting to the top of
