Continental 40307 Engine Timing Belt

Continental 40307 Timing Belt for Subaru

The Continental 40307 engine timing belt is built for Subaru valve train applications that demand accurate cam timing and durable belt construction. It uses EPDM material, timing marks, and precision-molded HTD 9.525 M teeth to maintain consistent engagement with cogged components.

Fits 2000-2009 Subaru Legacy, N/A. Fits 2008-2009 Subaru Outback, N/A. Fits 2003-2006 Subaru Baja, N/A. Fits 2002-2004 Subaru Outback, N/A, 4th Digit of VIN# B; interference engine application.

Key Features

• EPDM construction for resistance to heat, abrasion, and ozone exposure
• Precision-molded teeth for consistent contact with timing components
• Timing marks included for alignment during service
• HTD 9.525 M tooth profile
• 70.250 in. belt length and 1.063 in. top width
• 223 belt teeth for Subaru timing applications

Detailed Description

Continental part number 40307 is an engine timing belt for Subaru Legacy, Outback, and Baja applications listed above. The belt is made from EPDM and engineered to resist shrinking and elongation, helping maintain stable timing over service intervals. Its molded tooth profile supports accurate mesh with cogged pulleys, while the timing marks simplify alignment during installation and inspection. This part cross-references Gates T307 for the same application.

Common Replacement Reasons

• Cracked, glazed, or worn timing belt material
• Noise or irregular operation from timing drive components
• Visible tooth wear or belt stretch
• Service replacement on Subaru Legacy, Outback, or Baja timing systems
• Interference-engine maintenance where timing accuracy is critical

Installation Notes and Tips

Verify engine code and VIN details before ordering, especially for 2002-2004 Subaru Outback models with 4th digit VIN B. Replace the belt only after confirming pulley condition, alignment marks, and correct routing for the specific Subaru application. Because these are interference engine applications, follow the manufacturer service procedure carefully and rotate the engine by hand after installation to confirm timing alignment. Continental 40307 should be installed on the exact vehicle listed in the fitment data.

Quality Assurance

Continental timing belts are manufactured with materials and tooth geometry selected for stable operation in demanding engine timing systems. Part number 40307 is built to meet the fitment and construction requirements listed for the Subaru applications above.
