Just got a turbo off an ASZ fabia as a spare, but I've noticed theres a bit of shaft play, probably less than a mm in/out and a little side to side too. Not sure if its tolerable as the bearings don't have oil in or is this a sign that its bad? Its apparently off a car thats done 15k

Any help appreciated

Seeing as the turbo is dry of oil, there will be a little play, As far as i have always been led to believe though , In & out (Push Pull) play is far more detrimental than the Up & down play as the shaft & turbine will naturally centre under load / spin .... As long as you cannot get the turbine blades to fowl the casing......

I recently repalced a turbo on a Subaru Impreza & that had up & down play (30K Miles) but no in & out, I know they are a slightly different beast having no variable vanes but the bearing type is the same Etc. The Old one that came out sounded like casper the Ghost on spool up WoOOooHooo & had quite a lot of play in the shaft in all directions, The 30k replacement had no haunting sounds ..

Thanks for the reply mate. Think i'll call my local trusted garage to see if they mind taking a look for me, probably be able to tell a lot better than i can.

Would it being void of oil also cause in out movement or just side to side/up & down? The blades seem to just very lightly graze the housing when pushing slightly though :|

Definately increased play side to side with no oil .. Plus it is going to expand when hot so tolerances will lessen then ...... As for the in & out (Push / Pull) as you say , get a 2nd opinion or hopefully somebdy with one to hand can check theirs also, Devonutopia (Jason) normally has lots of spares hanging around

Cheers for the help matey will see if I can get someone to look at it. hoping its okay but feeling doubtful now

1mm is OK. Even the shaft on my brand new turbo moved a little tiny bit. I guess they can't be 100% rigid?
