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

Step 1:

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:

Attach the C mount to the rear bulkhead.

Step 5:

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:

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:

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:

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:

Press the hinge pin mount into place; hole down.

Step 15:

The rear hub spacers (for wheelbase) come in two sizes; thick and thin. Pic for size comparison. Nice fingers.

Step 16:

Attach the rear hub to the rear suspension arm. The 2 thin shims should be towards the back of the car.

Step 17:

Capture the hinge pin with the M3x4mm screw.

Step 18:

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:

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:

Build the rear camber link plate.

Step 21:

Attach the turnbuckles to the camber link plate, making sure the outer ball cups are swept up.

Step 22:

Attach the upper shock mounts to the shock tower. Note the orientation of the tower.

Step 23:

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:

Mate the CVD bone to the differential outdrive, then pop the ball cups into place.

Step 25:

Assemble the rear wing mount and rear body mount to the rear shock tower.

Step 25:

Your completed rear clip should look like this!
