BCBC MF127 Engine Camshaft Thrust Plate

Engine Camshaft Thrust Plate Overview

The Melling MF127 engine camshaft thrust plate is a standard replacement part for stock applications that require precise camshaft control. It is built to help restore timing accuracy when a worn thrust plate or button has allowed cam walk and misalignment.

Key Features

• Cast iron construction for durable engine use
• Standard replacement grade for stock-style service
• 4 mounting holes for application-specific installation
• Designed to help maintain camshaft position and timing specification
• Fits a wide range of GM V8 and V6 applications, including Chevrolet Silverado, GMC Sierra, and Cadillac models

Detailed Description

The MF127 camshaft thrust plate is used in engines that rely on a thrust button or thrust plate to control camshaft end play. When the original part wears, cam movement can affect timing and component alignment. This Melling thrust plate is made from cast iron and follows standard replacement dimensions, including a 1.679-inch inside diameter, 4.98-inch outside diameter, and 0.178-inch thickness. The MF127 is a direct service part for many Chevrolet Silverado, GMC Sierra, and Cadillac applications, as well as other GM platforms listed in the fitment data. This part cross-references MAHLE B32270 for the same application.

What It Is Used For

• Correcting cam walk caused by a worn thrust plate
• Restoring camshaft end-play control in stock engines
• Reducing timing variation from component wear
• Replacing a damaged or out-of-spec thrust plate during engine service
• Supporting proper alignment of valve train components

Installation Notes and Tips

Verify the engine’s thrust plate specification before installation and compare the part dimensions to the original component. The fitment data includes stock applications across multiple GM platforms, so confirm the exact year, make, and model before ordering. Use the MF127 only where a camshaft thrust plate is specified by the engine design.

Quality Assurance

Melling supplies engine valvetrain components for service and replacement use, and this part is built as a standard replacement thrust plate for applications that call for this design.
