MIP CVD's are driving me nuts

[shodog]

I have MIP CVD's on both my Son's and my T3's. I have a 19 turn motor and I have a 10Turn cranking out the speed. The problem is that I keep shearing the roll pins on the axles. I was out running them yesterday with my son and both our right side pins are sheared. Is there anything out there thats tougher?

hmm, i've never had that happen. maybe you could knock out what's left of the pin, and find some titanium round bar to use as a roll pin. cut it to length, and press it in.

By roll pin I assume you are talking about the pin on the outside of the hub carrier which connects directly to the wheel.
If that is the case then you need these:

If you buy them from asociated it is like getting robbed, almost $1 each.
You can get steel dowel pins at places like smallparts.com for much less, under $0.10 each

The problem you will have with these is that they do not stay in the axle when the wheel comes off, so they are easy to lose, make sure you have fresh locknuts on the axles.
I ordered some from smallparts,com in 3/8 and 1/2" lengths, and use the longest that will fit in the wheel slot.

ya know what, i think i thought shodog meant that he's shearing off the pin on the bone at the outdrive.

That's what I thought from the topic title, but those should be solid pins not roll pins.

i have an old pair of race prep rc10 dogbones. they have a roll pin, instead of a solid pin. they're the only one i remember seeing like that. i think the bone itself is hollow, too. they're really light.

It's the roll pin that fits in the slot on the wheel. they are so small in diameter that they continually break

then the steel pins will do the trick.
What some have done is to use a saw/dremel to elongate the slot in the wheel and then use 1/2" long roll pins, (which can be found at most well-stocked hardware stores.)
This method is especially helpful when the broken pin has mangled the slot on the wheel as it gives a nice fresh shoulder for the longer pin to rest against.

Thanks for all the advice guys. I going to try and find a small steel pin to fit the hole.
