turbo play
Turbo Mini Forums

hi, my first post here, been readin for a while now tho, im just gettin to the stage where my turbo lump is ready to go in, i've rebuilt the t3 and am a little worried as i have never seen this turbo running and there is some play on the shaft is this normal?
anyways cheers

there will be a little bit, thsi is taken up by the oil

try and measure it with some equipment (feeler gauges will do), i think mine had 0.24mm which was a low tolerence

this is up and down play, not side to side

ok, thanks. so what about side to side, should there be no play here?

tim

none

thats in the x direction, i.e. from left to right if the turbo is in the position that it would be when in the car

ahh ok, thanks nic, think ive got a little bit of play side to side :s not enough to touch the housing or anythinng tho,?

tim

Did you replace the bearings?

yeh, i did. im worried that the old ones may hav spun in the housing which would obviously make it bigger and the play would be on the outer of the bearing not the inner against the spindle, if that makes sence lol.

as above youls see some radial play, but there should be vertualy none if you pull and push the shaft "in & out"

im confused which way can you have play then... my turbo has slight play on it, not if i push on it but if i wiggle my finger on the shaft it moves a bit side to side i geuss. but i have seen brand new turbos do this also so do you mean no play in and out if you were to push on the shaft?

Searching is all you need on TurboMinis

Pull and push the shaft along its length and you should not have any. (thrust!)

Wiggle it up and down and you will have some. I rebuilt mine on sunday and it had what i would consider loads of play but i put in new bearings and a differant shaft that was not worn so i can only assume they are supposed to be that sloppy!

as nic said, about .2 odd mm for a t2, which to me looks like loads!
