Kato GE 44 Tonner

Scale:
N Scale


This installation uses the following decoder:

M1



This installation is for N Scale Kato GE 44 Tonner uses TCS M1 Decoder and was performed by Jim Starbuck Clinton, Iowa

Although designed as a powered chassis for a Japanese prototype trolley car, these wonderful little mechanisms are fodder for many kitbash projects due to their small size, low cost, simplicity and superb running qualities. This installation will be a GE 44 ton switcher, but the decoder install should be about the same for most any shell.

First, disassemble the motor, driveshaft, worm gear, pickup strips and trucks so there is a bare chassis.

Using a motor tool and files, grind a rectangular hole through the chassis that allows the decoder to inset into the frame. The M1 will just fit between the pickup strips.

I combed the pickup and motor wires back and glued them down using MicroScale crystal clear. There is just enough clearance under the driveshaft coupler for the wires.

When satisfied with the vertical clearance, tack the decoder into the chassis with crystal clear from the bottom side.

Place a drop of solder on the center of the pickup strips and glue them down into their centering pockets using crystal clear.

After the glue sets, solder the red and black to the pickups The orange and gray motor leads route to the back. I this case the motor is mounted on it's side with two sided tape to facilitate the narrow hood of the switcher.

Lighting wiring is then a straight forward process as well.

Important Soldering Tip

Please do not use any flux either liquid or paste on the mother board. It will damage it. Use only Rosin core solder approved for electronics use. 
We recommend to use only Kester "44" rosin core, SN63PB37, .015" diameter, part number 24-6337-0007.
This can be ordered from Techni-Tool under Techni-Tool part number 488SO157

Other solder tips

When stripping wire, only strip a tiny little bit of the insulation. Strip no more then a 1/64 of an inch. When the wire gets tinned with solder, the insulation will shrink back more. Try to not expose any more wire then half the length of the solder pad at most. In no case should solder or exposed wire wire ever be outside the boundary of the the solder pad you are attaching a wire to.
