We have been trying to reassemble a 15g using a new rebuild kit from turborebuild.co.uk. It all came apart ok and mostly gone back ok, EXCEPT...it is a real struggle to get the turbine piston ring to engage in the hosing without forcing. The book says "finesse it in, patience is needed and experience helps" . I have little of the latter and the former is running low. Looked at great vid on youtube from ARD Tuning and they made it look so easy you cannot even see how he does it, it just clicks in with a little wiggle.
Wecspent over 20 mins each trying to get the shaft with ring instaled to lock into the retaining bore, it just seems too large. Can this be?

Has anyone on here done much of this and got any top tips? Tbh its the first time i have been inside a turbo so i dont really trust myself not to overdo something and break it. Cheers WOZ
