Well guys. Here is your info!
How to rectify the 2nd gear spur stripping issue.
1. Adjust 2nd speed so the shifting is not so erradict or rapid. You want to tighten to two balls at top and bottom to give more space so the 2speed shoe is closer to the housing.
2. Dont run your tires too low. Go about 1mm bigger if your experiencing 2nd gear blow-outs. I believe what this does is keeps the rpms of the spur gear down and therefore will put less stress on it.
3. Changing from the aluminum to steel gear on the 2nd gear pinion. Part #t0736 , it has a duller edge and will not put as much stress on the spur gear.
4. Run the 18/24 Gear ratio on the pinion gears.
Mainly its believed to be perhaps a heat/friction issue. That if your car is in 2nd gear for awhile as well on a longer track that it will just heat up and melt.
On that note you might want to try an aftermarket spur (I will verify this myself). The low friction Delrin blue ones. This might help or worsen the issue so this is not a definent but its worth a try and I will get back to you guys on that. But wanted to throw it out there for others to test this.
This information was given to me from some friends @ mugen. I will try to get ahold of mike swauger as well and see his point on things and if they coincide with the issue and fixes.
But this information is surely different than what this thread has come up with so heres some new things to try guys.
Good luck. Happy Tuning. This info will be copied over to http://pro-hobby.net
