TCS T1 Decoder Installation for HO-Scale Hornby Class 06 shunting (switcher) Locomotive. It was performed by Robert Lewis of Tilehust, Reading, United Kingdom.
This is a Hornby class 06 shunting (switcher) locomotive. It is of the type of locomotive often found in "starter" train sets.
To remove the cab, the four lugs have to be gently pushed inwards using a small screwdriver, and the cab pulled off. Once the cab is off the bonnet section will also come away, it is held in position by 2 locating pegs at the front.
The can motor is held in place by the spring clip, using fine pliers it can be un-hooked from the retaining lugs. With the motor removed the capacitor should be un-soldered from the brush terminals. The ballast weight may be held in place by a small cross head screw underneath the chassis block, remove the ballast weight by prying the chassis apart between the front pair of wheels.
The TCS-M1 decoder leads were trimmed to 100mm (4") in length, the unused wires should be insulated. I have bundled the wires together using insulation sleeving to keep the installation neat. Solder the red wire to the right hand side brass pick up, and the black to the left hand pick up. These joints and the exposed brass must be sleeved to avoid contact with the metal motor can.
Replace the motor, making sure that the brush terminals are now facing upwards, re-fit the retaining clip ensuring the centre is resting against the plastic end cap of the motor, and not the drive shaft. Solder the orange and grey wires to the motor terminals. The decoder can be stuck to the inside of the body using double sided tape. Test the installation before finally re-fitting the body.
Important Soldering Tip
Please do not use any flux either liquid or paste on the mother board. Over time, the acidic properties of liquid or paste flux will begin eating away at the fiberglass PCB and will damage it. Use only Rosin-core solder or no-clean flux approved for electronics use.
TCS recommends the use of Kester "44" Sn63 Pb37, .015" diameter Rosin-core solder. Kester part number 24-6337-0007.
You can order this solder from the following retailers:
Digikey - PN:KE1110-ND
Techni-Tool - PN:488SO6775
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.
