Description

Product Overview

The National 100470 Engine Crankshaft Seal is a precision‑engineered component designed to fit the timing cover of the Chevrolet Silverado 1500. Constructed from a high‑grade polymer blend, the seal features a spring‑loaded multi‑lip configuration that provides a tight, leak‑free barrier against oil and contaminants. Its painted exterior not only resists corrosion but also adds a layer of visual protection, making it easy to inspect for wear. The seal’s compact dimensions—3.25 x 0.88 x 3.25 inches—and lightweight design (1.28 ounces) allow for straightforward installation without the need for specialized tools.

Usage

Whether you are performing a routine maintenance service, a major engine overhaul, or a DIY repair, the seal’s low coefficient of friction ensures smooth operation and reduces wear on adjacent components. Its design accommodates both OEM and aftermarket timing covers, making it a versatile choice for professional workshops and home garages alike.
