Installation Notes

Verify the shaft diameter, housing bore, and seal dimensions before installation. Clean the sealing surface and inspect the extension housing for scoring or wear that could affect the new seal. Confirm the transmission type on vehicles with notes such as Honda PSFA or Honda MDRA before ordering.
