Need some advise on rear ZX5 SP Outdrive

[eddiemori]

Hey guys,
I finally got my ZX-5 SP put together!
Bought it off my brother and fixed/replaced a lot of the parts!
But i need your help on an issue i noticed right away...
The rear right CVD(LA208) popped out from the outdrive(LA201) after i gave it some throttle!
it even chipped the some of the steel off of the outdrive! it went flying passed my laptop!
Anyway, i notice that when the car is on a stand the "pin?" part of the CVD is almost hanging out of the out drive! Obviously when there is a load on the rear suspension it seems to be fine. I'm worried that during a jump or at an akward angle it'll pop out/break the outdrive!
is this just an issue with my car? did i miss something in putting it together? if not what's the work around? has anyone else have an issue with this?

One way is limit the travel in the shock, spacer on the shaft under the piston stops the arms dropping, but there may be different cvd's on the sp.

check that you have the right arm, pivot and shaft combo'. If you have a true sp then the rear shafts should be silver and the arms should be short same as original RB5. With those black cvd's you should have mid-arms la243/um521 both should run with the narrow blocks and not the wide ones and both with the offset hubs not the original zx5 hubs. One last thing, the cvd shims should all be on the inside of the axle so that the shaft is pushed further in to the drive cup.



HTH Simon.

So i was very careful to order the right parts from Kyosho and make sure that i "restored" this zx5 to SP specs. In the SP manual, it is showing p/n LA258 as the rear CVDs and it appears to be the right one. Online pictures of that part is showing as a black CVD! This should be coupled with LA255 for the arms?? i'm confused now!
I've attached the exploded view of the rear suspension area. Am i looking at the wrong thing? has this been updated? any guidance would be much appreciated!

Update: So after some researching and looking at different options, i ended up replacing the swing shaft with a longer 62.5mm(UM510-01)! Now it's just right! Smooth without any issues of popping out of the outdrive!

And what coluor would they be?

[eddiemori]

Oh Oh! Silver. why?

[eddiemori]

Nevermind...
