Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX

The rear suspension on the Tekno EB410.2 is similar to the .1; beefy arms, anti-roll bar, aluminum arm mounts with press-in plastic pills, etc. The biggest difference is that the shocks are now mounted to the front side of the arms. This also means the anti-roll bar has to be re-located as well.

Build Notes:
The EB410.2 uses inserts for the hub camber links. They can install in multiple ways; arrows up/arrows down and holes inside or holes outside. Pay close attention to this during the step.

There are also multiple mounting options for the rear hub hinge pin; up, center or down. Pay close attention to this step as well.

Step 1:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
The EB410.2 comes with aluminum arm mounts. Here are the C and D mounts (C on the right, D on the left). You can also see the recesses for the pills.
Step 2:

Press a pair of 0° pills into the C mount…
Step 3:

…as well as a pair of 0° pills in the D mount.
Step 4:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Attach the C mount to the rear bulkhead.
Step 5:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Insert the droop screws into the suspension arms. Don’t worry about how much to screw in just yet; we can set that at the end.
Step 6:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Slide the hinge pins into place followed by the 1mm shim (thicker shim), suspension arm and the .5mm shims (thinner shims, x2 on each side). Pay close attention to the orientation of the parts.

Align the hinge pins with rear D block and secure with the M3x14mm screws.

Step 7:

Your assembly should look like this.

Make sure the suspension arms move up and down freely.

Now attach the lower anti-roll bar points to the arms.

Step 8:

CVD time. Start by inserting the barrel into the bone, then add a liberal amount of black grease as shown. Mate the axle to the bone and slip the pin through to connect it all together.
Step 9:

Build 2.
Step 10:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Assemble the rear hubs. Press a 6×12 bearing into the front of the hub, a 10×15 into the rear.

Feed the CVD through the hub, then slip the 2mm shim onto the axle followed by the axle pin and hex. Secure with the grub screw. A small amount of threadlocker is suggested here.

Step 11:

Here’s a look at the camber link inserts. You can see the arrows up and down, holes in or out.
Step 12:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Press a pair of arrow down/holes out into the rear hubs. We’ll be inserting the camber link ball stud into the outer hole.
Step 13:

Here’s a closer look at the assembly.
Step 14:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Press the hinge pin mount into place; hole down.
Step 15:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
The rear hub spacers (for wheelbase) come in two sizes; thick and thin. Pic for size comparison. Nice fingers.
Step 16:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Attach the rear hub to the rear suspension arm. The 2 thin shims should be towards the back of the car.
Step 17:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Capture the hinge pin with the M3x4mm screw.
Step 18:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Build the rear turnbuckles.

I like to use Chapstick on the threads to help lubricate when building. This also helps when adjusting the turnbuckles during tuning.

I used strawberry Chapstick so it keeps my car smelling fresh.

Step 19:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Your turnbuckles – note the orientation of the Tekno ‘T’ on the ball ends. 28.5mm is a good starting point.

And yes, the pictures in the manual do not match. Use the ball cups shown here.

Step 20:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Build the rear camber link plate.
Step 21:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Attach the turnbuckles to the camber link plate, making sure the outer ball cups are swept up.
Step 22:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Attach the upper shock mounts to the shock tower. Note the orientation of the tower.
Step 23:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Press the shock tower into place on the rear bulkhead followed by the rear camber plate (note orientation of the plate). Secure with the M3x14mm screws.
Step 24:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Mate the CVD bone to the differential outdrive, then pop the ball cups into place.
Step 25:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Assemble the rear wing mount and rear body mount to the rear shock tower.
Step 25:
Tekno RC EB410.2 4WD Buggy Build Part 4 – Rear Suspension | CompetitionX
Your completed rear clip should look like this!

Would you look at that – the back end of the EB410.2 is looking good!
