Jason,
Thank you for the pictures, they definitely help. Have you experienced any failures in those areas?
Once again thanks,
Norbert

Any ideas what could be causing rear diff bearing issues. I have done the grease fix with the sheild of and even backed the screws off 1/2 turn. I am only getting around 1 qualifer on the bearings. It is a 09 spec. The bottom of the chassis is very hot so I don't know if its shimmed to tight but the mesh feels good.



first your name is awesome.....unfortunately i had to get rid of my SRT....05 black on black :D

second....bud if your only getting one qualifier out of them then you really have some other issues that are causing the bearings to fail...the chassis is going to be hot no matter what, it acts like a heat sink for the motor almost so i would disregard that. What bearings are you using, stock? avid? others? How old is the bulkhead? and does it have the 09 bulkheads? becuase if you upgraded the car to an 09 and didnt upgrade the bulkheads there is a big difference between them in terms of tolerances.

Also, i will post a picture in the next couple days of what some of us team guys are doing to to help keep dirt out of the coupling and bearings. to describe it to you in short we are taking the rubber shock membranes, punching a small hole for the drive shaft to go through and gluing it to the tranny case giving you a homemade dust cover so you can put a little grease in the drive shaft area. try that, let me know how it works.



pics ? :wink:

Jason,
Have you experimented with different diff oils in your active diff? Your setup shows you use 7k in the truggy and I was wondering if you could explain the advantages of going lighter or heavier. I was thinking lighter might be better since it's going to lock under acceleration anyways? Appreciate all the help,
Norbert

Hello everyone,

I am very new at this so please forgive me if I ask stupid questions. In a few days I will go for my first race. I have been practicing at that track for a month or so and even though I don't expect much I would like to go there prepared. What should I do to prepare my XB808 to avoid disaster and also to avoid all those anxious moments at the track during therace?

Thanks in advance! :lol:

Hey Norbert, Sorry for the late reply.

No I have not tried too much in diff set up with my truck. To tell you the truth, other than shock oil its very rare that I ever change anything set-up wise with my truck. It runs so good as is that I just stick it on the track and drive the crap out of it....lol. It's just extra track to me and this way I can concentrate everything else into buggy. You may gain a little more from going lighter but, to me, 7k in truck could be about the same as driving 2k in the buggy because of the weight of the tires. So I know that if I use the active diff in buggy and I run light oil than the car becomes to twitchy so I apply that to truck as well. I don't think I would go lighter than 5k.

I would just check the car over and make sure all your bearings are in good shape, maitain the clutch, all screws and nuts are tight, put locktite on screws that require it, make sure you have the right tire selection and make sure they are properly glued and ready to go, and all batteries are charged.

As far a being anxious just rely on your practice, good maintenance, getting good clean starts by avoiding silly mistakes, avoiding getting tangled up with other drivers and drive your own race.

Congrats on your first race and good luck.

lotus here is the pictures i was talking about.....sorry it took so long.

holes will be different for front and rear drive shafts

rough up the surface of the tranny case and just CA glue or shoe goo them on. a silicone adhesive would be good as it might remove easier later.

if you do this you can pack a little more grease in the coupling lubing the cvd a little better all while helping to keep dirt out.

hobby fixin :lol:

I do the same thing and get up to 12 hours of runtime between drivetrain rebuilds (replacing all pins and bearings). I ran one set of 13x20 bearings for about 23 hours just to see if they'd last. The pins and couplings hardly wear at all because it's all packed up with grease.

What's up Jason,

I see you run your car all the time at Mike's in Houston. I just got an Xray 2010 spec, and was wondering what setup do you suggest for that layout? Thanks.

Mchuang, Hey how's it going? Sorry for the late response but give this set-up a try.

Let me know if you have any questions.

Thanks. On the camber, you show -2 all around, do you measure that on the Hudy setup station or just with a camber gauge?

A camber guage will work just fine.

Hello team Xray of America, I have just swithched to Xray from Associated and ran the 808 for the first time. It was a very smooth driving buggy and look forward to many enjoyable races with it. I was talked into this switch by my buddy who has driven Xray for two years and swears by it, I have also seen how durable the metals used are (it does not wear out)(compared to my rc8 did). I also have talked to Ryan Lopez and his dad numerous times and they have always been great, even let Ryan use my pit trailer at the PNBIII this year while I pitted with my buddy, because he has been really cool. I only have one need, I want more steering or rotation, and want to keep it stock (steering knuckles and caster blocks)I do have the aluminum suspension block though. Can you all give me some advice on this matter. The track I raced on was technical, but race on many various tracks, looking for a good base with as much steering while keeping it stock. I do have the rear arms all the way back and hubs forward, front arms are forward, rear ackerman holes for steering, and 553 in diffs, other then that box stock. Thank you for your time.

Welcome aboard!!! Yea that Lopez kid is alright....lol.

Where do you have your camber linkage set at on the shock tower and hub in the rear? The shorter the link the more rotation in the rear wich will help improve the steering.

Thank you Jason, I have the camber links at the box stock location for the 2010 spec instructions, not sure but I think that is middle or second from top on tower (can't remember if there are three or four holes) I am at work and not with the buggy right now :o(. Again thank you and sure I will be bugging you lots till I learn the characteristics of the chassis.

Also I have the conical pistons on the way and was wanting a good starting point for shock oil, I use associated shock oil for now.
