Thank you Herminator!

Got the 1 way together, and the drive gears are in my alloy shaft carriers. The bearings fit nice and snug into the carriers, no slop at all, I'm liking this car!

Hi Guys,

Dave Berger's setup from ROAR nationals is posted online. Check out www.alexracingusa.com

By the way, Berger also won the Brushless class last night at SoCal as well

The transmission is breaking in right now... I'll have to take it back apart to finish sealing, but I gotta buy some extra parts before it's done anyway, just want to have this step done with. I hooked up an old chamelion pro 19 turn motor to my Pulsar running at 2 volts and going to let it go 2000 seconds, then let everything cool down, and do it 3 more times. Is the stock shimming pretty much correct, or are you guys running the shims different than stock? Seems a bit tight.

stock shimming may not be correct, I normaly have two shims in one side of one of my diffs and none in the other side, my front one way I can use one on one side to get a nice fit, it takes time but experiment a bit.

I'll try to figure out what it needs after the drivetrain is done running for 8000 seconds. Hopefully it wont be too rough on me

I am also going to have to spray out the bearings and re-lube them with some royal oil, I think they have more resistance than the gears.

yeah the bearings come very full of thick grease, I found after a couple of runs some had managed to squeeze out some of the grease, especially at the wheel hubs.

I'm still just gonna do it the quick way and spray em out... I'm sure after the breakin is done, there will be a difference from when it started at the grease breaks down.

Just spray those thngs out and put some Royal Oil in those suckers and watch that drive train come alive!!!!! .. also you migh want to try a little re-shimming of the one way and diff to get the gear mesh smooth....
You have the time...do it RIght the 1st Time

I have the drivetrain silky smooth right now!

The front 1 way, I have 1 shim on either side, but have filed down the edges of both gears to get the right gap.

The rear diff has both spacers on the left side, and the teeth were not filed down.

I sprayed out the goop from the bearings and re-oiled them with royal oil, then ran it another 2000 seconds at 2.5 volts. I can spin the drivetrain so freely by hand now, one slight spin will coast for about 3 seconds with no rotating mass to keep the momentum going, it's amazing!

Just wait till you get the Web R2 and put the Ceramic`s in that diff even smoother
