The SKT42231 part number is also useful when cross-checking replacement options during service.

Key Features

  • Direct-fit engine timing idler for select Mitsubishi applications
  • Supports proper timing belt alignment and routing
  • Fits interference engine applications where timing accuracy is critical
  • Cross-references Gates T42231 and MN137248 for the same application
  • SKP replacement part number SKT42231 for service matching

Detailed Description

The SKP SKT42231 is an engine timing idler for Mitsubishi Eclipse, Galant, Lancer, and Outlander models listed in the fitment data. In timing belt service, the idler helps maintain belt path stability so the engine’s valve train stays synchronized during operation. This makes it a relevant replacement when servicing Mitsubishi Eclipse and Mitsubishi Galant timing components, especially on interference engine applications where timing integrity matters.

Use the SKT42231 when replacing a worn or noisy timing idler, or when performing a timing belt service and the existing idler shows wear. The part number SKT42231 can be matched against service records and replacement catalogs, and it cross-references Gates T42231 and MN137248 for the same application.

What It Is Used For

  • Eliminating timing belt noise caused by a worn idler bearing
  • Restoring stable belt tracking in the timing system
  • Replacing a damaged idler during timing belt service
  • Addressing timing concerns in interference engine applications

Installation Notes and Tips

Install this timing idler only on the Mitsubishi Eclipse, Galant, Lancer, and Outlander applications listed in the fitment table. Verify engine code and timing component layout before installation, especially on interference engine applications. Replace related timing components as needed during service to maintain correct belt alignment and synchronization.

Quality Assurance

SKP supplies replacement engine components for service applications, and the SKT42231 is cataloged for direct-fit use in the listed Mitsubishi timing systems. Confirm part number SKT42231 against the vehicle’s timing service requirements before installation.
