I got very lucky on my graphite gearboxes, the mold was perfect, and the stock shimming was perfect as well, once I break in the drivetrain for a few hours, it should be very free
Randy, I forgot that tip that you told me. Luckily I'm not too far into the build so I can still do that. Thanks for reminding me.

On the topic of shimming...has anyone ran just one shim behind the input? I ran the 3 shims for about 10 race days and the car was more free after each weekend. A local sponsored racer stated that he felt like it was ok to subtract shims...just wanted to check with this thread on the experiences you may have had with shim and gear life.

It will help the breakin quite a bit, just dont take off too much material, the real goal is just to slightly round the faces of the teeth...

It's ok as long as you keep an eye on the play, because once the gears breaks in the play will increase and if it increases too much it can cause stripping gears.

They shouldn't strip easilly, you'll hear about Evo 3's going through gears, but that's because the gear doesnt have proper support...

I run all 3 in the front and 2 in the rears. I tried running 2 in the front as well but the gears didn't look good after a few runs.

The reason that everyone seems to be running slightly different shimming is because the gearboxes are molded, and most likely have slight imperfections from one to the next...

Default gear sanding

So I am lead to believe some are sanding the oneway gears teeth?Is this for clearance and break in reaons?I have had 2 oneway gears go bad and need to know if this will help.Also I ran 2 shims in the front when I toasted those gears.Help! Otherwise the drivetrain is butter.

i would not recomend sanding it down steve from speedtech
posted a way to break in the gears. wich is basically shimming
as tight as possible without binding then using a slave motor
to run at low rpm for a few hours. this will seat the gears together
and this should apply to most shaft driven cars not just the
sd.

I do sand my gears lightly, just to barely round the edges of the teeth. I've done this on just about every shaft car I've owned, and they all have had extremely free spinning drivetrains...
