Detailed Description

Gates CHK166 is a timing chain component kit for 2011-2013 Nissan Juke and 2013-2018 Nissan Sentra applications. It is engineered around a steel chain with a 6.35 mm pitch and silent chain construction, along with plastic and steel guide components and included tensioners and sprockets. This kit is intended for timing drive service where worn chain components, noisy operation, or timing instability need to be addressed. The CHK166 reflects Gates timing drive expertise and is built to meet or exceed OE standards in function, fit, and performance. This part cross-references KTC1638 and KTC1641 for the same application.

Common Issues Addressed

• Timing chain noise from worn chain or guide components.
• Engine timing instability caused by stretched or fatigued timing drive parts.
• Rattle or irregular operation related to failing tensioners.
• Wear in sprockets, guides, or chain surfaces during timing service.

Installation Notes

Install the CHK166 during a full timing system service and verify camshaft and crankshaft timing marks before engine start-up. Replace related wear components as needed and follow the vehicle service procedure for chain alignment and tensioner setup. Confirm application details against the vehicle’s engine code and timing system configuration before installation.

Quality Assurance

Gates is a global supplier of timing drive systems in both original equipment and replacement markets. The CHK166 timing chain kit is built to meet or exceed OE standards in function, fit, and performance.
