thank you
cooldude.
This is a problem I once had with my 710 - it was mainly due to the clutch running hot. The heat of the clutch would cause the oil/grease of the bearing to run out, leaving them running simply metal-to-metal. These bearings don't last too long under these conditions. I, like you, was finding after three or four tanks that my bearings would be starting to blow.

The solution was easy - simply wash out the bearings with brake degreaser, let them dry and then spray them with WD-40. Although WD-40 is very light, it won't fly out of the bearings in the clutch.

I did this before the start of each day's run and I ran one set of bearings for a whole season without any further problems.

Cheers, Mark

Check the brakes not binding when the throttle is wide open. This will cause the clutch to overheat and heat the bearings as Mark said

Cheers

Has anyone heard when the K-Factory one-way/spool might be here in the states? Yeah I know I could look back in all of the posts, but I admit, I'm lazy......

Thanks for everyone's suggestion for fixing my understeer problem. I found this at another forum and wondered what everyone's thoughts are on this:

1. front solid, rear diff = understeering on corner entry; oversteer on power corner exit;

2. front 1-way, rear diff = oversteering on corner entry; oversteering on power corner exit;

3. front diff, rear diff = neutral on corner entry; neutral on power corner exit.

I'm running #2. What are you guys running?

drfritz: Thanks man! Lots of options for changing things on a race day.

You will also get the same results with caster clips changes
1mm clip all around neutral setting equal entry & exit arms in middle positon
1mm clip front 2 mm clip back neutral entry positive exit semi aggressive
0 clip front 3 mm clip back aggressive entry slugish exit arms forward
