Gates CHK128 Engine Timing Chain Kit

Timing Chain Kit for Toyota Corolla

Gates CHK128 is a timing chain component kit built for interference-engine applications in select Toyota Corolla and Corolla iM models. It combines the core timing drive parts needed to restore chain system function with OE-level fit, function, and performance targets.

Key Features

• Steel roller timing chains for durable valve train operation.
• Includes chain guides, tensioner, and drive sprockets for a complete timing drive service.
• Steel camshaft sprocket material for consistent timing component engagement.
• Built to meet or exceed OE standards in function, fit, and performance.
• Fits 2014-2018 Toyota Corolla and 2017-2018 Toyota Corolla iM applications.

Detailed Description

This Gates timing chain kit, part number CHK128, is intended for timing drive service on interference-engine Toyota applications where precise camshaft and crankshaft synchronization is critical. The kit uses steel chain construction with roller-style links and includes the related guides, tensioner, and sprockets needed to address wear across the timing system. Gates CHK128 is a practical choice when the original chain drive has stretched, become noisy, or lost timing accuracy. This part cross-references Cloyes 9-0917S and 90917SX for the same application.

Common Issues It Can Address

• Timing chain stretch that affects engine timing accuracy.
• Chain noise from worn guides or a weak tensioner.
• Rough running caused by timing drift in the valve train.
• Wear on sprockets that can reduce chain engagement consistency.
• Service needs on interference engines where timing integrity matters.

Installation Notes and Tips

Confirm engine code and fitment before installation, since this kit is listed for specific Toyota Corolla and Corolla iM applications only. Inspect related seals, gaskets, and timing cover components during service, and verify camshaft and crankshaft timing marks carefully during assembly. Because this is an interference-engine application, correct timing setup is essential before starting the engine.

Quality Assurance

Gates is a global supplier of timing drive systems in both original equipment and replacement markets, and CHK128 is engineered to meet or exceed OE standards in function, fit, and performance.
