The Key C 28 – especially the later version with brake shoes - is nice replica of an D&RGW
Class C 28. The only problem is: this engine should performe as good as it looks. For this conversion
I use a Faulhaber 1624 Volt motor (1,75 watts at 12 volt) which is a little bit slower than the
original can motor used by key. Together with a flywheel this conversion will end in a smooth and
slow running switcher for your „Antonito Yard".
Even if you are a not a skilled modeller, it won‘ t take longer than 1-2 hours to convert
one this engines.
Step 1---Remove boiler and cab from the frame by unscrewing the screw between the Cylinders
and the ones beneath the cab.
Step 2---Remove the old motor by unscrewing the two front screws and disconnect the wires
Step 3---For this conversion with the 1624 (12 volt) motor you could use the original
silicon motor coupling .
Step 4---Glue the motor direct to the gearboxframe (grey) or fill a small styrene
spacer 0,5 mm sheet styrene) between motor and frame. Connect motor and gearbox with the silicone
tubing. Check drive system by turning the flywheel. Give power to the motor, the drive system
must run nearly silent. When it runs perfect, glue the spacer in place
(ACC+ secure it the next day with epoxy).
Step 5---Mount the gearbox frame back into the main frame and mount superstructure
back to the frame and screw the locomotive together.
