Overview of Gates High Performance Automotive Timing Belt T131RB

The Gates High Performance Automotive Timing Belt T131RB is engineered for precise valve train operation in select BMW models. Designed with durable materials and a curvilinear profile, this timing belt supports reliable engine timing and performance.

  • Curvilinear (ii) profile for smooth engagement
  • Blue color for easy identification
  • Top width of 25 mm (.984 inches)
  • Pitch of 8 mm (.324 inches) with 127 teeth
  • Fiberglass cord material for strength and flexibility
  • HCR belt material for heat and wear resistance
  • Single belt quantity included
  • Pitch length of 1044 mm (41.1 inches)

Detailed Product Features and Specifications

The Gates High Performance Automotive Timing Belt T131RB features a curvilinear (ii) tooth profile that ensures consistent meshing with sprockets, reducing noise and wear. Its fiberglass cord reinforcement provides tensile strength and dimensional stability under high stress. The belt's HCR (High-Performance Chloroprene Rubber) material offers resistance to heat, oil, and abrasion, which is critical for maintaining timing accuracy in demanding engine environments. With a top width of 25 mm and 127 teeth spaced at an 8 mm pitch, this belt is designed to meet the exacting requirements of BMW engines.

Compatible BMW Models and Applications

This timing belt is compatible with various BMW models, including the 325e, 325es, 325i, 325is, 325iX, 525i, and 528e. It is specifically designed to maintain precise valve timing and engine synchronization in these vehicles, supporting optimal engine performance and longevity.

  • Maintains accurate valve timing in BMW 325i and 325is engines
  • Supports engine synchronization in BMW 525i and 528e models
  • Replaces worn or damaged timing belts to prevent engine misfires
  • Helps avoid timing belt slippage and associated engine damage
  • Reduces risk of belt failure under high-performance conditions

Installation Notes and Tips

When installing the Gates T131RB timing belt, ensure the engine is properly aligned according to manufacturer specifications. Since this belt does not have timing marks, careful attention to sprocket alignment is essential. Inspect related components such as tensioners and pulleys for wear and replace as necessary to ensure optimal belt performance. Proper tensioning is critical to prevent premature wear or slippage.
