Find the turbine end seal ring in your rebuild kit. Gently place it into the bearing housing seal ring bore. Square the ring in the bore and measure its end gap. It should show an end gap of at least 0.001 inch, but not more than 0.007 inch. Check this with a feeler gauge. Next, install the turbine end seal ring gently onto the turbine shaft and into its groove. Take care not to over expand this ring; it’s just like installing piston rings onto a piston.

Once this is complete, you can then install the turbine wheel into the bearing housing. Push the gap of the ring into the groove and lightly press the wheel and shaft into the bearing housing bore. There will be a taper to aid in the installation. This is a step where caution must be taken not to force it too hard. The seal ring will walk into place if you gently press down while slowly rolling the wheel around to seat the ring into its groove as it enters the seal ring bore. This may take a couple of tries to get it in without causing damage to the ring.
