Default Re: Re: Re: Thrust bearings...

Im running the rubber setup from the xray site, with blue22.5 in the front, white 17.5 in the rear, 30 xray oil, 1 hole all the way around (turned all the way to the right then 1 click back). The rear diff is in the low position, I raised it to the middle and it got worst. I also raised the front roll center and it didnt help either. I also tried CS22, 27, 32 with the same results. Im running on very very very high traction concrete. One last thing is that Ive tried sway bars with each size.

Have you try upstop? By installing shim(s) on the shock shafts.


Make sure you press on the car so the chassis is bottom out and try to lift the wheel up, install the shim(s) until you canít lift the wheel up anymore. That might help.

Just don't add too many shims or your adjusters won't work right if you have the adjustable pistons installed.

Tim,
I think komkit meant shims on the outside of the shock body, not travel limiting ones on the inside, piston adjustment will still work as it works at max extension not compression.

Also Midnight, turned all the way to the right (one hole open) then back one will be two holes open surely?

In no way am I bashing xray. I just need to know can I use my yokomo shocks or can I use these tamiya Part #: TAM53571. If so can I still use my yokomo springs and will the adjustable pistons still work. Sorry for the dumb questions, but a guy PM me and ask if I had any oil in my shocks, and at first I was like are you kidding me I just built them a week ago (15 packs). He explained that he had the same problem. He also said he switched to the aluminum bodies and they havent leaked since. I would rather switch to the aluminum 27 is cheaper than 65, and I can stay xray all the way around, but I dont want to dump 27 and still be in the same boat Im already in.

Once again sorry for being so long winded, but this car is off the chain until this traction roll problem.

Thanks in advance

BRO you may have to rethink that set up. The one on the web site is for rubber on carpet

I had traction roll problems on carpet..

Took an hour to solve...
1mm shims under rear camber links (at hub carrier)
rear 2 deg toe in
rear 2 deg camber

Tire sauce all the way to the edge of the tire but none on the sidewall. Check tires haven't come unglued, traction roll is just another setup challenge, sure it can be frustrating, but its something you have to learn to deal with no matter what you drive.

That was all I had to change, prior to those changes my car was basically stock.

The thing is that you have to set your car up like your driving on carpet. I also have the front downstop at 2 and the rear at 5.

I found everything except for the 50797 short adjuster 5 mm plastic lower end of shock front, can I substitute for something.

I used xray 5.8mm bal joint part number 303220 cut right above the hex, with Xray 5.8mm ball ends part number 303240 (the same ones you use for the xray shocks), but I did that because I wanted to put a button head scren threw the ball into the arm ...I have a habit of having the lower part of front shocks "pop off" during racing ...I cut them right at the red line:




I've actually got some tamiya 53640 on the way to see if I can accomplish an all the way threw screw setup for the tops of the shocks as well.

I used a button head 3x12 screw through the stock shock ballend and the stock ball/nut. Prior to that a light tap against the wall with the rear wheel would knock the lower shock ball end off the ball.

Works lovely now.

Bearing problems:

I have had three bearings go bad in a whole season of racing. two in the rear and one up front I have seen bearings lock up at the track and melt the hubs.

Hi,

LUCKY........... I'm still waiting to get a fk05. as Karting season is starting up soon most of the r/c stuff is on hold. and we were still fast with the 04 so........ also I really don't want to go to the Vegas race with a fresh undriven car....

Thanks

Try the Axiom thrust bearing! On the homepage of www.axiommotors.com
