Detailed Product Overview

Timken 710487 is an OE-style automatic transmission output shaft seal engineered for dependable sealing performance in transmission service. The seal’s reinforced outer case adds durability during installation, while the ribbed rubber inner diameter helps maintain contact on shafts with minor surface imperfections. Vent holes support lubricant circulation around the seal lip, helping manage heat at the sealing surface. This part cross-references National 710487 and SKF 17532A for the same application.
