| STEP 1 |
|
First you need to remove the motor and rear axle/wheel
assembly. Be careful not to bend the motor shaft spring too much and kink
it! I use an elastic to hold the motor to the chassis while I work.

|
| STEP 2 |
|
| Place a small flat screw driver under one end of the magnet
holder and pry up. Do this on the other side of the magnet holder as well
until the holder comes free. Once the holder is off the magnet and spacer
will also drop out. Pictured to the right is all the pieces that will be
left after removing the magnet holder. |

 |

|
| STEP 3 |
|
| Next we will need to remove the plastic area under the
magnet. I use a sharp exacto knife and it does not take long at all because
the plastic is very thin. The bottom picture shows the area to be removed,
it is the area marked in yellow. To the right we have the finished product. |

|
| STEP 4 |
|
| Once we have the plastic removed we replace the magnet
holder and then glue the plastic spacer to the holder with a little Ca. Be
careful not to get any glue on the magnet holder's mounts because we still
want the up and down movement. The bottom picture shows the magnet holder
back in place and the picture to the right shows the plastic spacer glued
in. |

 |
 |
| |
|
| STEP 5 |
|
| Next glue the magnet to the plastic spacer, again making
sure you do not get any glue on the magnet holders mounts. What we now have
is a full range of movement from the magnet, we can lower it almost to the
track surface or raise it back to factory position. |

 |
| STEP 6 |
|
| Remount the rear axle and motor and finish with any other
minor modifications you might have in mind like gluing axle bushings and
motor to their mounts. |
