Cummins Front Crank Seal with Wear Sleeve 89-18 5.9L / 6.7L

Cummins Front Crank Seal with Wear Sleeve (Fits 1989–2018 5.9L & 6.7L)

Give your Cummins engine the reliable protection it deserves with this premium Front Crankshaft Seal and Wear Sleeve Kit—the trusted solution to stop leaks and prevent premature wear for 3.9L, 5.9L, and 6.7L engines (1989–2018).

Key Features & Benefits

• Complete Repair Solution: Kit includes oil seal, wear sleeve, and installation tool for a professional, leak-resistant finish every time.

• Designed for Durability: Engineered by Cummins and top OEM suppliers to meet or exceed factory specifications, ensuring a perfect fit and long service life.

• Prevents Leaks from Worn or Damaged Surfaces: The included wear sleeve restores the crankshaft sealing surface, crucial when old seals have cut grooves or pitting into the crank—this new sleeve creates a pristine surface for your seal to seat against, virtually eliminating chances of oil leaks from uneven or damaged metal.

• Quality Sealing Components: Inferior or off-brand seals often lack the precise fit and advanced elastomer materials required to withstand the demands of heavy-duty diesel use. By choosing a genuine, top-tier kit like this, you avoid headaches caused by leaks, oil contamination, and the need for premature resealing.

• Easy, Accurate Installation: Includes a custom install tool to ensure the seal and sleeve are properly aligned and pressed in, further reducing risk of leaks or early failure.

Note: Once a wear sleeve is installed, always use this matching seal for future replacements, not the original factory-only seal.

Why Use a New Wear Sleeve?

• Most crankshaft oil leaks result from an uneven sealing surface—typically, years of rotation cause grooves and scoring right where the seal rides.

• Bolting on a new quality seal alone isn't enough; the wear sleeve is a precision-fit metal sheath that slides over your crank's nose, giving the new seal a perfectly smooth, round surface to ride on.

• This simple upgrade prevents future leaks, extends crank life, and is far more cost-effective than a full crankshaft replacement.
