Traxxas TRX-3 rebuild , (bulkhead #2630)

[Raul]

This is my Traxxas TRX3 buggy:

 

 

 

 

 

the front suspension bulkhead (part 2630) was broken.

 

 

This part is quite difficult to obtain due to the age of the buggy and the fact that it frequently breaks in jumps or collisions - it is in high demand. In this picture you can see the wishbones, bulkhead, axles and other elements of the front suspension:

 

 

There is another Traxxas black bulkhead part, ref. 2530, from the Bandit buggy that is wider. It has the holes marked in red in the same relative position and the part would have to be cut along the yellow lines to make it an alternative.

 

 

Once it has been cut, it is screwed on since the 3 holes on each side match in relative position on the chassis, subframe and lower arm.

 

 

This photo shows the alternative bulkhead compared to the original.
 

 

 

 

We place the suspension tower and lower arms. With the chassis and subframe screws, the bulkhead is firmly attached, but the halves are joined in one piece with epoxy adhesive as seen in the picture:

 

 

Finally, just 2 more holes need to be drilled in the bulkhead for the bumper:

 

 

In the following pictures, the final appearance of the buggy with the vintage electronics:
* Sanwa SRC-2322RS 40Mhz receiver
* Sanwa SM-102 servo
* LRP Ics 8066 75A electronic speed controller with XT60 connector
* Kyosho Kspeed 15T motor.

Great work!!

 

would a alloy bulkhead not have worked??

I personally would've added at least a swing arm reinforcement, there ought to be some chinese special at the right spacing. 

 

This is just going to happen again, it tore the pin out of the housing - a swing arm reinforcement would fix the two axle pins together, meaning you can't pull them out. Something like these.

 

 

Just, of course, fitting. Or, like Gaz said, straight to an alloy bulkhead, if available.

 

edit: not your fault, but them phillips screws giving me the itch. 😁
