Timing Cover Idler Gear for Diesel Engine Timing System SKU: QT31164362

When your timing idler gear wears out or loses teeth, your engine timing becomes erratic, causing hard starting, rough idle, and potential valve damage. This replacement idler gear restores precise timing chain or gear coordination, ensuring your engine runs smoothly and maintains proper valve timing.

Why Precision Matters

• Exact tooth count and pitch match original specifications for proper timing
• Heat-treated steel construction handles constant engine stress and temperature cycles
• Precise machining ensures smooth operation and long service life
• Proper timing prevents costly valve and piston interference damage

When your engine won't start consistently, runs rough at idle, or makes timing-related noise from the front cover area, a worn idler gear is often the root cause. This replacement part fits within your timing cover assembly and works with your existing timing chain or gear set. Professional installation recommended due to timing requirements.
