So, parts are coming slowly for Kakes 17mm conversion for the front end. I am basically going use the parts made for the 4x4 slash and run the stub axles up front without the rest of the cvd shafts connected. Fortunately the stub axles are included in the Tekno RC 17mm adapter kit, so I didn't have to buy cvds and waste money.
So why would I do this?
The stock slash 2wd and Pro-Line Pro2 run a 5mm front axle which means that to fit 17mm (1/8 scale) wheels you need an a 17mm adapter. All the adapters use a hex nut that fits over the wheel nut threads and yet fits inside the adapter housing. Many of these adapters use a hex nut that end up failing beacuse the they are too weak and thin. In addition this setup sandwiches the adapter to the front bearings to hold it in place and causes the bearings to bind up and wear out quickly. If you spend money on ceramic bearings the last thing you want is to watch them get destroyed after a few runs. So, if you need the front to be as free wheeling as possible (as is the case with max speed running) there needs to be a way to hold 17mm (1/8 scale) front wheels on without inhibiting the front wheel bearings from spinning freely.
On to my ideas to solve the problem. As pictured a Tekno 17mm adapter kit is made for the Slash 4x4 front end and ONLY THE REAR END of the Slash/Rustler 2wd. So you have to get the Tekno front steering blocks made for the Slash 4x4 that has been converted to running a 6mm front cvd axle.
By now you have 6mm stub axle (with 17mm adapter kit) and the steering hubs that they fit into. The next part is to fit them into the caster block. ***( I have not yet confirmed this part of the build)*** If you are running a traxxas front A-arm then the slash aluminum caster blocks seem best, but if you are running the Pro-Line ProTrack A-arms then use the Pro-Line aluminum caster block. The differences will be the width of the caster block attachment point to the front axle. ***(Again, I have not yet conformed this, the caster block might not make a difference, they could be the same width)***
Ugh...so, for now we have our front stub axles, the 17mm hubs and the caster blocks (the steering blocks are on the way) its time to put it together aaaaaaaaaand shit!
The Tekno 6M (6mm) setup is WAY shorter than the stock 5mm axle. Meausred from the innermost bearing to the 17mm wheel hex, they are 29mm (stock) vs. 22mm (tekno) and I'm not sure that the steering block is going to compensate for such a wide disparity. It looks like the M6 steering block does hold the axle further to the outside but I won't know how much until they are delivered. So for now I'm waiting, but my mind is racing. I may be able to change out the 17mm adapter with a longer one from somewhere else or contact Tekno and ask if there is an option that they offer that I missed.
Fun times 😉
