SKF VKML91004A Engine Timing Chain Kit

Overview

SKF VKML91004A is an engine timing chain kit built for OE-style component replacement in compatible Toyota and Scion applications. It combines the chain, tensioner, guides, camshaft sprocket, and seal in one matched kit to support proper timing system service.

Fits 2004-2006 Scion xA, N/A; Fits 2004-2006 Scion xB, N/A; Fits 2004-2005 Toyota Echo, N/A; Fits 2005-2009 Toyota Prius, N/A; Fits 2006-2018 Toyota Yaris, N/A; Fits 2012-2019 Toyota Prius C, N/A.

Key Features

• Roller timing chain design with timing marks for accurate installation reference.
• Includes chain guides and a tensioner for a complete timing service.
• Camshaft sprocket and seal included for matched component replacement.
• Engineered for proper chain engagement and reduced friction between components.
• SKF VKML91004A supports OE system recommendations for timing chain service.

Detailed Description

SKF VKML91004A is assembled as a coordinated timing chain kit rather than a mix of separate parts from different sources. That matters in engine service because timing chain, guides, tensioner, sprocket, and seal all need to work together for stable valve timing and consistent operation. The roller chain construction, timing marks, and included guides help maintain correct chain tracking and sprocket engagement during repair. This part cross-references Toyota 135060Q030 and 135230D010 for the same application.

Use this kit when servicing timing chain wear, chain stretch, guide wear, tensioner issues, or sprocket-related timing concerns on Toyota Prius, Toyota Yaris, and related applications listed in the fitment data. SKF VKML91004A is a practical choice for technicians replacing timing components as a system instead of piecing together individual parts.

Common Uses

• Corrects timing chain stretch and related noise.
• Addresses worn guides or a weak tensioner.
• Restores proper chain-to-sprocket engagement.
• Helps resolve timing irregularities from worn valve train components.
• Supports engine service after timing system inspection.

Installation Notes

Verify engine code and fitment details before installation. Follow factory timing procedures, align the timing marks carefully, and inspect related valve train components during service. Because this kit includes multiple timing components, clean assembly and correct torque procedures are important for reliable results.

Quality Assurance

SKF timing chain kits are assembled to follow OE system recommendations for timing chain replacement, with matched components selected for coordinated operation and long service life.
