Super 300 CVD install

PARTS & SUPPLIES NEEDED
Super 300 CVds
AX10/SCX10


TOOLS
Dremel
Drill & assorted bits
Usual hex drivers & screwdrivers

I had originally setup my SCX10 with some Axial CVDs and they have been surviving just fine. In fact, considering the abuse of my heavy rig and the Holmes Hobbies handwound motor, I am impressed with them. However, I decided I'd go ahead and install a Puller aka "partsbreaker".
So, along with some MIP driveshafts I decided to put in the Super 300 CVDs in.


Note that you'd use the same process to install them into an AX10 so this writeup will cover both.


1. Step 1 is to get the front axle apart and out of the truck.


2. From there, take everything apart until you are left with the two axle halves, the diff removed and the ring gear off of it.

3. Now it gets fun. You will notice that the Super300 CVDs are too big to slide through your ring gear. So you need to enlarge the hole for the CVD to pass through. If you have a standard ring & pinion it's easy to enlarge. If you have hardened gears it is a bit more work. I started off with some small "diamond" files and that was taking forever ... but with a dremel, it's fairly easy. Just go slow and let the tool do the work. Otherwise you will break the grinding bit like I did.


4. Now you can start to reassemble everything using the Super 300 parts in place of your original parts. Take note that the Super300 CVDs are not the same length on both sides. I found out by installing them incorrectly the first time. I also like to grease the crap out of my axles to help prevent rust since I go in the water alot.


5. My next step was to modify the Super 300 hexes so that my axial 1.9 wheels would fit. I used a dremel with a cutting disc. Just take your time and it should come out fine. I like to make one slice parallel to the face then come back to get it all flat. I tried drilling out my stock SCX10 hexes but couldn't seem to get them just right.


6. I also had to drill out the wheel itself for the larger CVD. I wish there was a way to avoid this but there really isn't.


7. The last thing to do was to drill out my scale hubs to thread over the larger CVD. I used a small unibit for the part that threads on. Once installed, I found the hub hit the nut before it bottomed out on the wheel. So I used the dremel to open up the hub just a hair and it went right on..


Now that I have things beefed up I can work on installing that motor!
