Shunt Kit Assembly Instructions

Step 1 - Apply a tiny amount of flux paste to the end of the spring.....
Step 2 - Wipe away excess flux.....
Step 3 - And tin with solder.
Step 4 - Slide the copper pin through the spring and solder them together using a pin vice. Be very careful NOT to use too much solder.
Step 5 - A bullet proof pin and spring.
Step 6 - Slide the pin into the threaded part of the heat sink and add spacers.
Step 7 - Install brush and shunt assembly into the brush barrel. Tighten with small needle nose pliers.
Step 8 - Attach shunt wire to the pin, allowing approx. .050 clearance between the wire and heat sink for brush wear. Remove excess pin. Again, TINY amounts of flux go a long way.
Step 9 - IMPORTANT: Place the car on a piece of track with rail. The rail acts as a heat sink when soldering to the shoes. Shape the shunt wire, cut to length, and solder to the shoe.
Step 10 - Make sure the shunt wire clears all metal parts that may cause a short including the front axle. Make sure the shoes have sufficient up and down movement. On my car I use the chassis side rail as a stopper. Time to go race, happy hunting.
