Detailed Description

INA ZC-9-0900S is an engine timing set for valve train service on select Hyundai Sonata, Kia Optima, and Kia Rondo models. The kit is assembled to cover the essential timing chain wear items in one package, helping reduce the need to source chains, guides, and tensioners separately.

This specific kit does not include gaskets or a drive sprocket. Part number ZC-9-0900S is also referenced as INA Global Number 559 1401 100.

What It Helps Fix

• Timing chain noise from worn chain components
• Chain slack caused by a weak or worn tensioner
• Guide wear that can affect chain tracking
• Timing service needs on high-mileage Hyundai Sonata, Kia Optima, and Kia Rondo engines
• Incomplete timing repairs when individual parts are replaced one at a time

Installation Notes

Verify engine code and timing system configuration before installation. Replace worn timing components as a set, and inspect related seals, gaskets, and sprockets during service since this kit does not include gaskets or a drive sprocket. Follow factory timing procedures and torque specifications to ensure correct cam and crank synchronization.

Quality Assurance

INA positions this timing chain kit as a premium replacement solution for timing service. The manufacturer also notes that its chain additive, used in certain applications, is formulated to reduce friction during break-in and lower run-in wear.
