Slide the compressor wheel on and line up the marks carefully to restore
the balance. Put on the nut. The torque varies from 20 to 40 in-lbs in
various sources, plus extra 90-120°. Ideally, you need a small
12-pt socket for the nut, I just clamped it between two wooden blocks and
used a torque wrench on the turbine end.

This Garrett T25 turbo is found on 1991-1998 Saab 9000, 1994-1998 Saab 900
and 1999 Saab 9-3. There are certain differences between the models, but the
cores are almost identical, so you might find this useful even if your unit
is somehow different from those pictured. The goal of this job was to rebuild
a turbocharger using new seals and bearings from a service kit.
Tools and supplies:
- 14 mm six-point socket (turbine end nut);
- 13 mm spanner wrench (exhaust housing bolts);
- 10 mm wrench (wastegate actuator);
- 8 mm twelve-point socket, did without it (compressor wheel nut);
- Torx T15 screwdriver (thrust bearing);
- small torque wrench with an inch-lbs scale;
- large and small snap ring pliers;
- gear puller;
- engine oil;
- degreaser and cleaning supplies.
