I know this isn't the correct location, but I hope one of you 960 owners still has some good 950 & 950r parts they're looking to sell and keep a fellow racer on the track.

It would be great to get a used, but not used up 950r roller.

Anyone?

thanks in advance-

Besides gluing the bearings in, has anyone found a solution to the excessive play in the bearing eccenters? I'd hate to plunk down more money on the aluminum versions if the problem hasn't been addressed.

Hi SMcpot, the reason because we use the allu eccenter is to have a little bit more tops speed. I run a lot with the plastic and i found no problem. I don't glue the bearings. Can you please describe where you have play? We are talking 960 rigth? One way or rear axle. Thanks

How do the alloy ecentrics increase top speed?

With Aluminum Eccenters, the bearings stay more true and do not wobble where speed would be lost. By keeping the bearings true, and vibrations lessened the drivetrain can spin more freely. Although you may not feel the increased top speed, you can definitely see the results through a radar gun.

Never thought of that. May have to get some then.

Does anybody have the part# for the aluminum eccenters?

Our Nationals are in a few weeks on the biggest track in the country, so every little bit helps. I have an RB Speedline Xenon R coming as well, should be fun.

This is actually on a 950R, Paolo...figured I'd get more answers here since the 960 shares this part

The plastic on this particular car is all new, as are the bearings and eccenters (converted to the 51T solid axle, as well). The bearings just fall out of the eccenters, with the slop being especially noticeable up front; the belt, also new, is somewhat loose in the default eccentric position and doesn't really give me an option to tighten it further since I will definitely have to have it at its tightest setting already. Just wondering if this was "normal" and if the aluminum eccenters maybe fit the bearings better.

EDIT: I'm having this problem with both the front and rear eccenters.

Thanks Greg. Good looking out

I think the best option is to ship the parts to the office to see what's going on. To be honest i don't remember having this problem on the 950R (but it's a long time since i drove that car). I definetely can tell you that the plastics eccenters in the 960 are fine. I think you are already in contact with someone at the office. I am sure we will find a solution

Yup....I contacted Serpent and they told me to send them in. But I find it unlikely that two pair of these parts bought at separate times could be faulty without more people having the same problem, so I figure that this is just the way they are and I'll try to make them work. Besides, I really want to run the car and would rather not be without them for so long

Thanks for the reply!

EDIT: I found that the 960 eccenters are not, in fact, the same as the 950R's....in case anyone else thought otherwise.

Paolo M

Well, my suggestion will be to take some teflon tape (plumbing) and wrap the outside of the bearing (use just enough to cover the outside bearing. This can help you to make the bearing fit tigth on the eccenter
Hope this can help and sorry for the inconvenience
