Gates CHK178 Engine Timing Chain Kit

Timing Chain Kit Overview

The Gates CHK178 timing chain component kit is built for engine valvetrain service where OE-level function, fit, and performance matter. It is a direct-fit timing chain kit for select Kia and Hyundai applications, including Kia Sedona, Kia Sorento, Hyundai Santa Fe, and Hyundai Genesis models.

Key Features

• Steel timing chains with a silent chain design for controlled operation.
• Includes steel camshaft sprockets, chain guides, tensioners, and drive sprockets.
• Plastic and steel construction used across key components for durability and wear resistance.
• Engine timing chain kit engineered to meet or exceed OE standards.
• Gates CHK178 is part of the Timing Chain Component Kits line.

Detailed Description

Gates CHK178 is an engine timing chain kit designed around the components needed for timing drive service. The kit uses steel chain material, a 6.35 mm chain pitch, and a silent chain type to support precise valve timing operation. With guides, tensioners, and sprockets included, this kit addresses the core wear items in the timing drive system and helps restore proper synchronization in the engine.

Gates builds timing drive systems for original equipment and replacement markets, and this timing chain kit reflects that background with OE-standard fit and performance targets. This part cross-references INA US ZC-9-0771SA for the same application. CHK178 is a practical choice for timing service on Kia Sedona, Kia Sorento, Hyundai Santa Fe, and Hyundai Genesis applications where the timing drive has reached service limits.

What It Is Used For

• Restoring correct camshaft and crankshaft timing after chain wear.
• Replacing noisy or stretched timing chain components.
• Addressing timing drive issues caused by worn guides or tensioners.
• Servicing engines with timing chain rattle or synchronization concerns.

Installation Notes and Tips

Verify engine code and fitment details before installation, since timing chain applications can vary by model year and engine configuration. Inspect related timing drive components and sealing surfaces during service, and follow the manufacturer’s timing procedures closely to maintain correct engine synchronization.

Quality Assurance

Gates states that its timing chain component kits meet or exceed OE standards in function, fit, and performance. The CHK178 part number is supported by Gates’ experience in timing drive systems across original equipment and aftermarket applications.
