B4 Rear Drive pin a touch short?
 

Noticed where the drive/roll pin sits in the hub of my B4 rear wheels that they are getting a little worn rather quick, the pins seem to be a little shorter than they might be which could be a factor?

Anyone else had this, if so, any idea of a good solution, perhaps some slightly longer pins?

Just me?

I'm not sure what you mean...

My car has some solid pins which are the right size for the driveshaft hole, and the right length for the wheel slot. These were on the car when I got it. The only problem is they fall out when you take the wheels off. The losi split pins used in the XX4 etc may fit, i'm sure they are longer than the associated ones. Might have to try that one myself!!

Erm...the drive shaft comes through the hub bearings and there is then a pin, referred to as a 'roll pin' i believe that goes through a hole in the drive shaft. This pin then engages in the wheel to provide the drive transfer to the wheel?
Might have just answered my own question actually: http://www.sosidge.com/?p=418

3/4 the way down this guy mentions the same problem and has replaced them with 'nortech' drive pins, who are Nortech?

No, same for everyone!

Nortech Racing supply the longer, solid pins. I think Losi do some longer split pins also.

Hmmm..anyone got any info on the Losi split pins?

I had a quick look, I think the roll pins only come with the driveshaft stubs as a kit? Might be wrong.

Hmmm...sounds like Nortech might be the answer, anyone got a weblink to them? Tried Google without much success?

dude you haven't looked hard enough ;)

Check out Northy, he's a member here. The link to his shop is in his sig ;)
