Final solution for the 808 diff bearing problem

Bren Ralls · **Posted:** Thu Aug 19, 2010 08:57:45

The xt8 & some options for the ec required the drive pins to be secured by just a grub screw, neither where secured like the 808. Unless you used a good quality loctite the pin would vibrate out, a tip was never done on this as most dremeled a small flat on the pins which solved the problem. Xray have now released a specific pin now with groove.

My original plan was similar to what you did but finding NEW parts to do what I wanted was a real challenge. I could buy all the ragged out Xt8's I wanted on Ebay but Who wants someone elses worn out ride. In the end I feel better about this setup. Just got home from my first race on this setup and it was flawless! :lol:

Good to hear. Did it handle any differently?

My setup does not change the car so it felt exactly the same. The piece of mind felt way different though! :lol:

The car reacts as normal, no difference. Except it rolls easyer after You releace the gasthrottle into corners beacause of the new smooth driveline. Extra milage is also a nice bonus.
I have ran 4 gallons on my setup and still working perfectly. Its a relif not to have to check the bearings. No more long nights worring about the bearing problem. I finished 6. in the nationals round 2, and 5. in nationals run 3, and two clubraces as well WITHOUT a single problem.

At this point I would just like to see a new truggy with a better driveline. I was one of the guy's before who was really hoping for a new truck release. I am glad now that Xray waited. Now the chances of it having driveline issues will have to be less.

Hello,

I have followed XRAY's solution concerning the difd bearings by adding grease between the pinion bearings, and in the metal ring provided by the 2010 specs. I did everything correctly but I see that now the wheels don't spin freely since the grease slows them down. Is this natural/correct?

Thanks

3 bearings have much more resistance than 2 bearings. So Your assumptions are correct.

Rumors say that Xray will come with a new racecar next year. And with a new driveline just like the one I made here. A brand new car and not an upgrade.

Not sure, but usually around december/january. No point of releasing a new car in the middle of a season.

Just saw Josh Wheeler's car pics from NeoBuggy. Guess what...

Lauri can you post a link to that photo on here. I hate trying to navigate that website?
