Detailed Description

Mahle A230 is an engine harmonic balancer repair sleeve used to renew the sealing surface where the front crank seal contacts the balancer. The nickel plated formed steel sleeve is engineered to fit over a worn hub and provide a smoother running surface for the seal, helping reduce leakage caused by groove wear. This part is listed as OEM standard and is suited for service work on a wide range of Chevrolet and GMC applications, including Chevrolet C1500, Chevrolet K1500, GMC C1500, and GMC K1500 platforms. The A230 part number is also referenced in interchange listings for FEL-PRO 16205 and Rol TC11327.

What It Is Used For

• Oil seepage at the front crank seal area
• Grooved or worn harmonic balancer sealing surfaces
• Seal wear caused by an uneven hub finish
• Service repair on high-mileage engine assemblies
• Restoring a proper sealing track without replacing the balancer

Installation Notes and Tips

Inspect the balancer hub before installation and clean the sealing area thoroughly. The sleeve should be installed squarely so the seal contacts the new surface evenly. Verify application by year, make, and model before ordering, since fitment spans many Chevrolet, GMC, and related platforms. Compatible applications include Fits 1990-1998 Chevrolet C1500, N/A and Fits 1988-1998 Chevrolet K1500, N/A, along with many additional listed vehicles.
