Detailed Description

The CHK188 timing chain kit is part of Gates Timing Chain Component Kits, a product line focused on timing drive service parts for engine repair. This kit uses steel roller chains with an 8 mm pitch and includes the major wear components needed when servicing the timing system.

What It Helps Address

• Timing chain noise from worn chain or guide surfaces.
• Chain stretch that can affect valve timing accuracy.
• Weak or inconsistent chain tension.
• Wear in sprockets that can disturb timing drive operation.
• Service needs when multiple timing components are due at once.

Installation Notes and Tips

Confirm engine code and timing system configuration before ordering, since timing components must match the exact application. Inspect related seals, gaskets, and adjacent wear parts during timing service, and follow the manufacturer service procedure for cam and crank timing alignment. The CHK188 part number should be matched to the vehicle application before installation.
