I have finally find the reason of my probs today.Bad slipper and slipper shaft bearing destroyed.
For maintenance i have buy U3365 slipper maintenance set ( originally made for cat sx but on the cougar car parts catalogue)
The small bushing between the bearing is shorter on the cat so if you fit the maintenance kit like that on the cougar without to compare the bushing lenght ( what i didn't do) you may experienced that kind of problem.
i'am sad for my son because he loose two chance to go to A final in our two first national.
Difficult for a young boy to accept to be beaten by mecanical problem instead of being beaten by better driver.
