Idler Gear Tab Washer for Perkins 212 and 248 Diesel Engines SKU: QT0921246

When an idler gear tab washer fails or goes missing, engine timing components lose their critical locking mechanism, leading to gear movement, timing issues, and potential catastrophic engine damage. This precision tab washer locks the idler gear securely in position, maintaining proper timing chain tension and gear alignment in Perkins 212 and 248 engines.

Why This Part Matters

• Prevents idler gear rotation that could throw off engine timing
• Factory-spec dimensions ensure proper gear retention without binding
• Heat-treated steel construction withstands engine vibration and thermal cycles
• Essential safety component that prevents costly engine rebuild scenarios

Without this small but critical washer, your engine's timing system becomes vulnerable to catastrophic failure. S&H Parts stocks the exact replacement your Perkins engine needs to stay reliably timed and running strong.
