The Build – Part 4
In this step I’ll be installing the one-piece center bulkhead, spur gear and belts. I’ll also be installing the front and rear differentials as well as the shock towers. A lot of steps coming up, but everything goes together quite easily.

Build Notes:
- Everything goes together well with this step. No special notes to share.

Team Associated TC7 Build - Top Deck/Bulkhead - Step 1
Step 1: The first order of business is to attach the one-piece center bulkhead. Blue threadlocker suggested here.

Step 2: Next, assemble the spur gear. Use a small dab of blue threadlocker to ensure the screws stay put.

Step 3: Slip a 20T pulley on each side of the spur gear assembly. Press until you feel them ‘lock’ into place.

Step 4: Press a 4×8 bearing into each diff pulley, then slide the gear shaft through and secure with the 6mm screw. A light dab of blue threadlocker is suggested here.

Step 5: Ring the rear belt round the spur gear assembly and attach to the center bulkhead. Yes, only one screw on one side holds this pulley in place, so I suggest some blue threadlocker to keep this baby in place.

Step 6: Ring the front drive belt around the spur gear assembly (opposite side of the rear belt pulley) and feed it to the front. Wrap it around front spool and insert the spool into the bulkhead. Make sure the flange on the cam rests inside the groove on the bulkhead. Press firmly into place.

Step 7: Now wrap the rear belt around the rear diff and insert into the rear bulkhead. Same deal with the cam flange and bulkhead groove applies here. Note the orientation of the cam – Hole #7 towards the back.

Step 8: Assemble the four bearing caps as shown, making sure to include the 1mm shim under each ballstud. Note the orientation of the flat spot on the bearing cap; they should be facing foward.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 9
Step 9: Attach a pair of bearing caps to the front bulkhead. A light dab of blue threadlocker is suggested.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 10
Step 10: Attach a pair of bearing caps to the rear bulkhead. A light dab of blue threadlocker is suggested here as well.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 11
Step 11: Feed the carbon fiber top deck between the front belt and attach to the front and rear bulkheads. Insert the screws only a little way, then tighten down in a criss-cross pattern. Again, a light dab of blue threadlocker is suggested.

Step 12: Attach the front shock tower to the front bearing caps.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 13
Step 13: Attach the rear shock tower to the rear bearing caps.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 14
Step 14: Press the 4x7mm bearings into the aluminum steering bellcranks.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 15
Step 15: Assemble the steering rack as shown – ballstuds (with 1mm washers), 4x7mm bearings and the TIN 3.25mm ballstud. Slip the steering rack bushings up through the assembled rack and attach the two bellcranks. Blue threadlocker is suggested here.


Team Associated TC7 Build - Top Deck/Bulkhead - Step 16
Step 16: Slide the assembled steering rack over the aluminum steering posts and attach to the chassis with the 3x6mm screws (yes, blue threadlocker here as well). The instructions mention slipping the steering post spacers onto the steering posts at this point, but let’s leave them off for now. Unless you use a screw to keep them in place, they’re going to fall off every time you attach a new piece to the chassis (and that’s alot!). We’ll add them later.
