turbo rebuilding... do it yourself??? (Garrett Guide)

[alan pritchard]

I recently did this on a garrett unit and it seemedb simple enough, as long
as your not replacing the turbine or compressor you should be fine, as long
as you mark the posiyion of these parts on the shaft you should be ok, if
replacing either the whole unit would, in theory, need to be rebalanced.  On
the Garrett unit it is quite simple, i dont know how this relates to kkk's
though:-
remove the compressor housing top half, to access the compressor wheel.
You should be able to find a socket to fit the nut, its 12 sided on the
garrett, but a 12 sided socket fits, i believe it is 10 or 11 mm
you will probably have to stop the shaft from spinning,  On the exhaust end
of the shaft is a triangular protrusion, one piece with the shaft, on the
garrett a 9/16" socket fitted snugly over this.  It takes some torque to
shift the nut.  the compressor wheel may be stiff to pull of the shaft, be
very careful because the blades are very fragile.
you should then be a ble to see the thrust bearing and one of the axial
bearings.
You should be able to access the others by removing the exhaust housing and
withdrawing the shaft. This is as far as i have been and it all seemed
straight forward.
You should be able to buy bearing and seal kits from a good turbo stockist.
Hope this is of some use!!!
