Detailed Description

Mahle A346 is built for rear crankshaft seal repair where the original sealing surface has become worn, scored, or uneven. The nickel plated formed steel sleeve provides a durable repair surface, while the 0.013 in wall thickness supports a tight seal at the crankshaft. This makes it a practical service part for rear seal repairs on vehicles such as the Toyota Celica, Toyota Corona, Toyota Pickup, and Toyota 4Runner, along with select Chrysler, Dodge, Plymouth, and Mitsubishi models. This part cross-references FEL-PRO 16266 for the same application.

What It Helps Fix

• Rear main seal leaks caused by crankshaft wear
• Oil seepage from a grooved sealing surface
• Repeat seal failure after prior repairs
• Uneven crankshaft surface contact at the rear seal area
• Service issues on high-mileage Toyota Pickup and Toyota 4Runner engines

Installation Notes and Tips

Inspect the crankshaft sealing area before installation and confirm the sleeve seats fully on the rear seal surface. Clean the shaft thoroughly so the nickel plated formed steel sleeve can install without debris or burr interference. Verify the application by year, make, model, and rear position before ordering Mahle A346.
