<<<<<<<<< JK Scorpion 2
This is a Scorpion 2 in the process of being rebuilt. New axle bushings have been installed, aligned, and soldered to the chassis. A new front axle has been installed and soldered to the chassis. A new rear pan support is installed and soldered to the pan. ---------------------------- Here is what the completed chassis looks like. Note the installation of floating pin tubes, front wheels, new leadwire and wire keepers. <<<<<<<<<<<<<<<<<< |

1. The most important aspect of building a chassis...the chassis must be straight. Often, even a new chassis is bent during shipment. Whether building a new chassis or rebuilding an existing chassis, use the back edge of your tech tool and a tech block sized piece of glass to make sure that each section of your chassis is flat. If necessary, use pliers to carefully straighten the chassis to its original shape.
2. The proper installation of the rear axle bushings is also very important. Pictured above, you can see that I have installed new rear axle bushings. The bushings are held in place with an axle and two old rear wheel hubs. Proper installation requires that you use a caliper to measure the axle height (at each bushing) from the bottom of the chassis. It may be necessary to raise or lower one of the bushings to equalize the measurement at each bushing. Once you have the bushings aligned in the chassis, solder them to the chassis.
The second part of the axle bushing installation process, is to fine tune the alignment of the bushings in relation to the axle. Minor repositioning of the bushing upright may be necessary to reduce friction. Take your time with this part. Reducing friction (drag) increases speed and reduces strain on your motor. When the bushinge are positioned properly, the axle should fall out of the bushings when the chassis is turned on its side.
3. Installation of the front axle is the next step. I like to purchase axle material in 36" sections. It is far more cost effective and allows you to install a longer axle that can be cut to size later. The plating on the inside of the front axle uprights on the chassis needs to be removed. The axle should be securely soldered at both areas where it passes through the chassis. |
