BCBC MG329 Engine Camshaft Thrust Plate

Overview

The Melling MG329 engine camshaft thrust plate is a standard replacement component for applications that use a thrust button or plate. It is made in the USA and built to restore camshaft control when wear has affected timing accuracy and component alignment.

Compatible with a wide range of Chevrolet, GMC, Pontiac, Buick, Cadillac, and Oldsmobile V8 applications, this MG329 thrust plate is a direct service part for stock-style engine builds. It is commonly selected for Chevrolet C3500HD, Chevrolet Tahoe, and GMC Yukon applications where camshaft endplay control matters.

Key Features

• Hardened steel construction for durable wear resistance
• Standard replacement design for thrust button and plate applications
• Two mounting holes with 7.0 mm diameter
• 43.0 mm inside diameter and 68.0 mm outside diameter
• Made in the USA

Detailed Description

The MG329 is engineered to replace a worn camshaft thrust plate and help return timing components to their intended specification. When a thrust plate wears, cam walk can develop and create misalignment in the valve train. This part is designed for stock applications across Chevrolet C2500, Chevrolet K1500, GMC C2500, GMC K1500, and related GM platforms, making it a practical service part for maintaining proper camshaft location. The MG329 part number is also referenced by interchange number 10168501.

What It Helps Address

• Camshaft walk caused by a worn thrust plate
• Valve train component misalignment
• Timing variation from excessive endplay
• Wear-related loss of camshaft control
• Need for a standard replacement during engine service

Installation Notes and Tips

Install only on engines that call for a thrust button or thrust plate component. Inspect the camshaft, timing set, and related wear surfaces before assembly, and replace worn parts together to maintain correct endplay control. Verify dimensions and application details against the engine build before installation.

Quality Assurance

Melling manufactures this thrust plate in the USA and positions it as a standard replacement part for stock engine applications. The hardened steel construction supports consistent service use in valve train repair and rebuild work.
