BCBC S827 Engine Timing Crankshaft Sprocket

Overview

The Melling S827 engine timing crankshaft sprocket is a standard replacement part built for stock applications that require precise timing gear engagement. It uses high alloy steel construction and a single keyway layout to support accurate crankshaft timing in a wide range of GM V8 applications.

Compatible with Chevrolet Silverado, GMC Sierra, and Chevrolet Camaro applications, the S827 is a fitment-based choice for engine rebuilds and timing service. The Melling S827 is also cross-referenced to Cloyes S827 and Standard Ignition S-827 for the same application.

Key Features

• High alloy steel construction for timing gear durability
• Standard replacement design for stock engine rebuilds
• 22-tooth sprocket configuration
• Single keyway layout
• Manufactured to required specifications using current production processes

Detailed Description

The Melling S827 crankshaft sprocket is part of Melling’s timing gear and sprocket program, which includes individual components for engine rebuild and timing service work. This sprocket is engineered from high alloy steel and built to standard replacement specifications, making it suitable for engines that need a direct timing component replacement rather than a modified setup. The 22-tooth design and 1.612-inch inside diameter support proper timing chain engagement and crankshaft indexing in compatible GM applications such as Chevrolet Silverado, GMC Sierra, and Chevrolet Camaro. The Melling S827 is a practical choice when restoring factory timing system function during a rebuild.

Common Uses

• Worn or damaged crankshaft sprocket replacement
• Engine timing service during rebuilds
• Restoring proper chain-to-sprocket engagement
• Addressing timing noise caused by worn gear teeth
• Replacing a stock timing component in GM V8 applications

Installation Notes

Verify tooth count, keyway count, and inside diameter before installation. Confirm engine application and timing set compatibility against the vehicle’s service information before assembly. Clean mating surfaces and inspect the timing chain, gears, and related components during installation to avoid repeat service.

Quality Assurance

Melling manufactures this sprocket to required specifications using high-quality materials and current manufacturing processes. It is intended for stock replacement use in supported applications and is part of Melling’s timing gear and sprocket program.
