CKRC FT Dig

So in this pic then, the outdrive you see with the hole in it is not the outdrive that you sand flat... correct. The one you sand flat engages the one you see in the pic somehow? Thanks...

correct, you file a flat on the output from the trans. On the opposite end of the one on the dig has a slot cut into it that will mate up with the trans output to lock it into 4wd

thats a set of CDW's done using a handfile

left corner you can see the original aluminum one, definitely worn out

One thing that I didn't really think about with this dig is that it mounts to the spur gear side, which I guess is opposite of the VF.

If you get a chassis made for the VF (like the Black Widow from MFM) it's not going to work out just right. You should definitely get the undrilled skid, because the pre-drilled just doesn't work.

Also... I got 3 brass bushings. One big one for the main shaft, one for the slider, and one that was the ID of the slider shaft, but it had a shoulder on the outside. The directions just say "Assemble the dig and put it on"... so what is that other bushing for? It works without it...

The third one is for the R2D tranny, you dont use it. The actual dig pieces are packaged from RC4WD for their tranny so its in there.

I think that 3rd piece would com in handy of you wanted to mirror your tranny though as you would have to flip the plate. I think I saw someone do that.

Could have been mine.

Honestly, I had a terrible time installing my dig. The allen head screws included in the kit were too long and hit the tranny case with 1/8" left to go before they would actually tighten against the outermost plate. The screws included in the kit are the same length as my tranny case screws. The delrin spacers included in the kit were also too long and I couldn't attach the motor plate until I cut those down. Not to mention, only two screws were included in the kit itself and I had to supply one extra long screw for the dig mount tab farthest from the motor. Basically, the dig rocks but the hardware package is inadequate. Be prepared to supply your own screws and a dremel to pollish and cut some of the parts to make it work.

Had the same issue with the long screws hitting the case, but washers took care of that. My only issues with the kit were the poor instructions and a packaging problem. All the pieces were thre though and it works.

Nope, wasn't that one. Just kidding, nice work. Did you have to drill the plate to accept the bushing?

Edit: I guess you did as it looks like there's a little JB weld holding it in place.

Same problem here. I did the washer fix also but the issue im seeing is there is so much slop in the main bushing that when the servo moves it back into 4wd mode it doesnt want to engage. The pressure on the link from the servo angles it just enough that it just spins and wont drop in.

The binding everyone was talking about from over tighening the mount screws is cause from the slot in the main shaft not being perfectly centered so it gets tighter every 180 degrees. File the slot just a little bit and you can tighten the mount screws all the way.

FYI to anyone ordering one of these. If your rig has seen alot of use get a new drive shaft for the rear end to cut. A well used one wont slide well once its cut short due to wear on the exposed pieces that will now be inside. You can save yourself alot of work spending the extra 6 bucks on a new shaft (or get the shorty MIP ones from TTR)

thank you.


yeah drilled it for the bushing but was a bit oversized, no side to side wobble but could pull it out easily. put a small hair line amount of jb on it and been working great since.
