Bachmann 47: Preparing the
Locomotive
Following the manufacturers' recommendations for running-in, ensure that the
locomotive is performing smoothly and to your satisfaction generally. Deal with any
issues now, especially those covered by warranty or your basic statutory rights as
customer, before making any modifications.
Separate the body moulding from the chassis block of the locomotive according to
the manufacturer's instructions. Store the body retaining screws safely away.
Gently slide four cocktail sticks between the body and chassis block, one at each
body retaining clip (seated in a slot in the clear plastic moulding underneath each
cab door window), just far enough to hold the clips and body sides sufficiently apart
that the body may be slipped easily off the chassis block.
Make a note of the identification of the terminals on the circuit board to which the
two wires leading to each bogie are connected. Note also to which side of each
bogie they go. Pop off the insulated sleeves from the terminals and disconnect the
wires leading to the bogies. It might be necessary to desolder them but they may just
be passed through holes in the terminals and retained by the sleeves.
Select one of the bogies and undo the screw which retains the bogie pivot in the
c hassis block. Drop the bogie out from the bottom of the block. The cardan shaft
joining the motor to the bogie will either come with the bogie or be retained at the
motor end. Either way, remove it but note that the ears on each end of the cardan
shaft are of subtly different shapes, so record which end is which.
Assign the bogie to one or other of your sets of etched bogie parts, marking the
bogie drive, drive shaft and chassis block accordingly.
Similarly remove the other bogie.
Fix the four sole plates to the lower face of the chassis plastic moulding as shown,
using an epoxy resin glue or double-sided tape.
