When renewing radial sealing ring, coat sealing lip (1) only with engine oil prior to installation.
The previous instruction to fill 1 g or 1 cc longterm lubricating grease between dust and sealing lip is no longer valid.
NOTE: Grease prevents the beveled webs of sealing lip from returning the oil (away from actual sealing point).
