- 720 uses same length shocks for both front and rear. Already
marked on my shock of how much weight oil should be used.
|
 |
- You may have to use a hinge pin (not a drill bit) to enlarge the hole with a Dremel at the
A-arm and anti-roll bar mount in order to ensure the smoothness of the front suspension.
- The reason for using the hinge pin instead of a drill bit is to make sure a
more precise measurement without binding.
|
 |
- Most option parts of S710 can be used in 720 as well, for example,
Aluminum Anti-Roll Bar and the front big bumper.
|
 |
- The front suspension part is so easy to install.
|
 |
- Just follow the track and push the upper arm in.
|
 |
- Once it's installed, and it's easy to take it out too.
|
 |
- I changed one-way bearing instead of the gear diff.
|
 |
- Before you screw in each hole, better use a few drops of bearing
oil, especially the screw hole in all A-arm.
|
 |
- This is the brake part in 720.
|
 |
- Better use (6mm x 0.8mm x 0.3mm) shim between the E-clip,
otherwise it will be too loose in brake shaft.
|
 |
- Also you need to shave down the set screw a bit (See
picture below), otherwise the set screw will be too sharp and damage
the chassis.
|
 |
|
 |
- The rear part is also very easy to take it out.
|
 |
|
 |
- You need to polish all metal ball before you install the ball
joint in rear anti-roll bar.
|
 |
|
 |
- When you assemble the gas tank, make sure it fits to the radio plate.
|
 |
- Drill the small hole in receiver holder.
|
 |
- Better use the option anti-roll bar, as picture shown.
Part#:803169
|
 |
- Use sand paper to shave down the white spacer, otherwise the ball
bearing will be too wide and will not fit the belt.
