300k-500k on wet astro.

When I changed spur gears, the new spur gear doesn't tighten down into the plastic piece. The spur is barely attached...

So this weekend I switched to 500k in the CD and roached my first spur. I'm now wondering if it might be too much for it when running gear difs. However I very carefully replaced the spur and rebuilt the dif and it lasted through the race program and a practice beforehand today with no issues. I'm going to keep running 500 and see what happens. One thing to note is that when replacing the spur you'll want to be careful not to tighten the screws down too far as they can actually push up on the area where the two halfs of the dif meet and can cause leakage or worse break the case. Just be cautious.

This weekend at the Reedy, Jared was running 750k and I was running 1mil and neither of us had any spur problems so i'm not sure what the issue is

I will start by saying that I have had my gear diffs for about a year and a half and the center diff for about 2 months. I have 500k in the center diff and 5k front/7k rear diffs and the only issues that I have had are the center leaks a little. It almost sounds like the motor adjustment to the spur is a little off or the throttle is still at full tilt while landing causing some stress.

Gear diffs

Do you run gear diffs in ZX6 or ball diffs? I was running gear diffs but just recently switched to ball diffs not sure I like it yet but I wanted to see what others are running

When I assembled my zx6.6 all I had was 100k for the center diff. I just received gears diffs for the front and rear. With 100k in the center what should I put in the front and rear ones? Hard pack medium sized track. Lots of traction.

7 or 10k in the diffs for hard pack good traction. 100k is probably too light in the center on everything except loose dirt track. If it feels like your car has no punch and/or you are wearing the centers of your front tires are wearing really fast you should go up on diff fluid. I would recommend starting at 300k and go up from there as needed or try 100k and see if it works for you since its already in there

For those of you running gear diffs, are you also using the metal bevel gear or the plastic one? If you are using the plastic one, I assume it is holding up pretty good or do you replace it frequently? Thanks!

I don't think that you can use the plastic pinion gear for the gear diffs. The tooth angle is different and it doesn't match. You have to use the metal one and with a little white lithium grease it hardly wares at all.
