Melling BT216 Stock Replacement Timing Belt Idler Pulley

The Melling BT216 is a stock replacement timing belt idler pulley engineered to meet or exceed original equipment manufacturer (OEM) specifications. Designed as a direct-fit replacement, this idler pulley plays a critical role in maintaining proper timing belt tension and routing within the engine's valvetrain system.

Over time, timing belt idler pulleys are subject to bearing wear, metal fatigue, and material degradation. A worn or failed idler can cause belt misalignment, increased noise, premature belt wear, or catastrophic timing failure. Replacing the idler pulley as part of any timing belt service is strongly recommended to ensure the long-term reliability of the entire timing system.

Key Features:

• Manufactured to meet or exceed OEM requirements for fit, form, and function
• Sold as an individual component for targeted replacement
• Helps reduce timing belt noise caused by slack or misalignment
• Prolongs timing belt life by maintaining consistent belt tension
• Built to high material and component quality standards
• Ideal for use during engine rebuilds or full timing belt service intervals

Melling recommends replacing the timing belt idler pulley during every timing belt replacement or engine rebuild. The BT216 is compatible with select Mazda applications including the 929 and MPV. Cross-reference part numbers include: 222-216BT, 7216, 9-5216, BTMA10R, T60288, and TBT470B.
