A340H, A340H

Bearing Adapter
Part No. TO-WA-16

Sonnax offers aluminum stator cap/bearing adapter TO-WA-16 for use on both impeller- and turbine-side in Toyota A340H and A340E units. Adapter TO-WA-16 along with thrust bearing CH-N-1 replace the impeller-side bearing, bearing race and stator cap, while adapter TO-WA-16 plus thrust bearing JA-N-7 replace the turbine-side OE bearing, bearing race and stator cap.

Improved performance over the OE bearing assembly.

For impeller-side replacement, the bearing-side pocket diameter of the impeller hub needs to be enlarged to 2.827"/2.835" for the CH-N-1 bearing to fit.

For turbine-side replacement, the height of the outer wall of the turbine hub bearing pocket needs to be reduced by .020" for proper clearance when using the JA-N-7 bearing.
