Sonnax flanged impeller hub TO-90-25G can be used to replace worn or damaged hubs in Toyota A340H converters.

Featuring an oversized bearing pocket, TO-90-25G is specifically designed and machined for use with Sonnax thrust bearing CH-N-1 and bearing adapter TO-WA-16. This combination of parts adds durability to the impeller-side bearing assembly over the OE bearing and bearing race, and eliminates the rework needed with Sonnax TO-90-5G or OE impeller hubs.
