Detailed Description

MAHLE A221 is an engine harmonic balancer repair sleeve used to renew the seal surface on a worn balancer hub. When the original surface develops a groove from crankshaft seal contact, this sleeve helps restore a smoother running surface for the front seal. The nickel plated formed steel construction supports consistent sealing performance in service applications, and the OEM Standard grade aligns with repair expectations for Jeep and Dodge engine maintenance.

This part cross-references FEL-PRO 16210 for the same application. It is a practical repair choice for Jeep Wrangler, Jeep Cherokee, and Dodge Dakota owners addressing balancer hub wear during front engine service.

What It Helps Fix

• Grooved harmonic balancer sealing surfaces
• Front crankshaft seal leakage at the balancer hub
• Seal wear caused by repeated contact on a damaged hub
• Oil seepage from the front of the engine
• Repeat seal failure after prior repairs

Installation Notes and Tips

Inspect the balancer hub before installation and confirm the sealing surface is clean, smooth, and free of debris. Measure the existing wear area and verify the sleeve seats evenly over the damaged section. Follow the vehicle service procedure for the specific Jeep or Dodge engine, and replace the front seal if it shows wear or hardening during service.

Use the A221 part number and vehicle application details to confirm the correct repair sleeve before assembly. For Jeep Wrangler, Jeep Cherokee, and Dodge Dakota service, matching the sleeve to the balancer wear pattern is important for proper seal contact.
