good call, bc i couldnt get it to seat, the rubber ring slips out-hmmmmm??? just keep trying?

also the diff appears to be smooth but really tight (backed screw 3/4 per insttructions), as if the diff lube with the kit is too thick-any thoughts here, build error?


maybe the same o ring issue..checking

I've put pressure on o-ring with needle while I've been trying to slide rings on outdrive. I've simply pushed o-ring inside one place at time and did it for whole diameter. Wasn't difficult to do and didn't take me too much time either.

got the o ring on--its much better--but still cant all the cam settings to clear the frnt sway bar on severe lean angles

as for the diff, i flipped the snapring clip so the square edge is on top-much better now

thanks!

Thanks for tip on diff cups. Not having a CX manual I missed that bit.
(even raced the car on Sunday with them loose)
I too found the sway bar touching the cups, and what I did was to turn the holders around (needed a small bit of filing), this moved the angled part of the bar away from the cups.
Seems to work, but the end ball bits are only half on.

Putting rear bar on front wont work as it tangles with the shock springs.

I have this problem also, although it seems to run fine. Can you explain in more detail what you did i.e turning the holders around ??
Thanks

with the spur facing the motor option-is it normal that the spur gear pulley has about 1mm of left to right play (on the layshaft)?

it seems ok but maybe a washer between the layshaft bearing and layshaft set shaft is needed? or is the play actually a good thing?

I found that if I put the o-ring inside the insert, and then slide that over the outdrive, it goes together easy and snug. I'll see if it sticks on the track tonight.

the 2 black roll bar holders that sit on the bulk heads
rotate them 180 so they sit against the raised section of the bulk head
(you will need to file some of the black plastic away at an angle where the grub screw goes through, not too much but just enough).
This will move the roll bar back about 8mm

And before you say a gear diff isnt always the best option etc etc, remember racing on goat tracks, a ball diff is shot in 2-3 runs if your lucky.
Gear diffs are on the way Bradd. Schuie announced them a few weeks ago. I dont' know ETA, but they are on the way.

Can the CX chassis be used on the LP ?

(am looking at the soft weave version, outdoor racing)

Just Googled, ok a Spec R Diff.
I would have though that with Schumachers impressive history that they would have made a gear diff with their own spin on it. (same expectation as with Xray)
The Spec-R's are better than nothing, but a logn way from the perfect solution.
