• Curvilinear (II) profile for precise tooth engagement
• HNBR-based belt construction for heat resistance
• Fiberglass cord reinforcement for strength and stability
• Blue belt color for easy identification during service
• No timing marks
• 25 mm top width, 8 mm pitch, 127 teeth, 1044 mm pitch length

Product Details

Gates High Performance Automotive Timing Belt T131RB is part of the Gates RPM timing belt line, a product line focused on engines that operate at higher speeds, higher cylinder pressures, and greater thermal stress than standard street applications. The curvilinear tooth profile and fiberglass reinforcement help maintain accurate timing engagement, while the HCR belt material supports consistent performance in demanding engine environments. This part number is used in BMW timing belt applications including 1982-1993 BMW 528e, 1984-1993 BMW 325e, 1985-1987 BMW 325e, 1986-1987 BMW 325es, 1987-1993 BMW 325i, 1987-1991 BMW 325is, 1988-1991 BMW 325iX, and 1989-1990 BMW 525i. This part cross-references Dayco 95131 for the same application.

Common Problems This Belt Helps Address

• Worn or stretched timing belt causing inaccurate camshaft timing
• Heat-related belt deterioration in performance-oriented BMW engines
• Tooth wear that can lead to timing noise or synchronization issues
• Service replacement for interference-engine timing maintenance
• Fitment needs for BMW 325i, 325is, 325iX, 525i, and 528e timing belt service

Installation Notes and Tips

Verify engine code, model year, and timing system configuration before installation. Some BMW 528e applications note use with a retrofit tensioner pulley, so confirm the correct setup before service. Because this belt has no timing marks, follow factory timing procedures and align all engine timing components carefully during installation.

Quality Assurance

Gates manufactures this timing belt for high-load, high-temperature engine service using reinforced materials selected for durability and timing accuracy. It is engineered for interference-engine applications where correct belt condition and precise installation are critical.
