Detailed Description

National 710674 is an engine crankshaft seal designed for the front position and built to match metric service dimensions. The seal’s 50.000 mm shaft size, 70.000 mm housing bore, and 11.000 mm width make it a direct-fit sealing component for many GM applications, including Buick Enclave, Chevrolet Traverse, GMC Acadia, Cadillac CTS, and Chevrolet Impala front engine service. National has supplied sealing products for decades, and this oil seal reflects that focus with a fluoro-elastomer construction and spiral-lip profile for stable sealing at the crankshaft.

This part cross-references Gates 19573 and Timken SL260014 for the same application. The National 710674 part number is also used in interchange searches for OE replacement matching on front crankshaft seal service.

What It Helps Address
