Detailed Description

INA ZC-9-0730SX is an engine timing set engineered for timing chain service on select Nissan Murano and Nissan Maxima models, along with additional Altima, Quest, Pathfinder, and INFINITI coverage. The kit is built to replace the primary wear items in the timing drive system, helping restore proper chain control, tension management, and guide support during engine repair. The part number ZC-9-0730SX also cross-references INA Global Number 559 1621 100 for the same application family.

INA states that its timing chain kits are assembled with the essential components needed to complete the repair correctly on the first service. In certain applications, the kit may also include gears and sprockets; this listing confirms chain guides and a tensioner are included, while gaskets and drive sprockets are not. For Nissan Murano, Nissan Maxima, and INFINITI QX60 timing chain service, this kit provides a premium replacement path for the specified engine timing components.

What This Timing Set Helps Address

• Timing chain noise from worn chains or guides
• Loss of chain tension from a fatigued tensioner
• Timing system wear found during engine teardown
• Service replacement on high-mileage Nissan and INFINITI timing drive assemblies
• Restoration of chain tracking and timing system stability

Installation Notes and Tips

Confirm engine code and timing configuration before installation, since fitment varies by model year and application. Replace all listed timing components together during service to avoid repeat labor, and verify timing marks carefully during assembly. This kit does not include gaskets or a drive sprocket, so those items must be sourced separately if required by the repair.
