Most Lima diesels and electrics share a common style of chassis,
which can be seen below. The exceptions to this are the class
09, 20 and 67.
The chassis consists of a power bogie with pancake motor and a
trailing bogie, which will have either one or two pick up wires
coming from it.
The bodies vary in their removal. most just unclip at the sides,
but some (Class 47 included) must have their buffers plled out
first as these act as a lock to hold the body on.
Here is a class 47 chassis with buffers and body removed:
It is necessary to isolate the motor. Remove the wire between
the eft hand terminal and the bogie (Circled in Green). If there
is a pick up wire from the rear bogie detatch it from the motor
and re-connect to the bogie. Otherwise a length of wire will
need to be soldered to the bogie that will reach the position of
the decoder.
The capacitor (Circled in red) can be snipped or carefully
twisted of with clippers.
The pick up wire from he trailing bogie clip has been
disconnected. The pick up wire connecting the two bogies has
been snipped, stripped, bound and tinned ready to connect the
black decoder wire.
the decoder is fitted. Grey to LH terminal Orange to RH terminal
(Circled) Red direct to the brass clip and black to the bound
wires.
Check it on the programming track, Test it, give it a new
address, pop the body back on and its done.
The class 50 was next (This has only one pick-up on the trailing
bogie)
And its done:
The class 26 is much the same - but shorter
The class 40 next. The tower arrangements on the bogie allowed
for very easy soldering access:
