446-1524 Manganese Bronze Circle Blade Wear Strip for Cat Motor Graders

Aftermarket 446-1524 manganese bronze/brass wear strip for selected Cat motor grader blade and moldboard guide assemblies. The U-shaped strip has a reference length of 120 mm and a nominal wall thickness of 9.5 mm. Legacy cross-reference: discontinued part number 5T-8366. Serial-number verification is required.

Full Description

The 446-1524 wear strip is a U-shaped manganese bronze/brass component designed for selected Cat motor grader circle blade and moldboard guide arrangements. It provides a replaceable contact surface that helps maintain component engagement and protects the blade, guide brackets and support structure from direct wear.

The current reference specification identifies a 120 mm overall length and a nominal thickness of 9.5 mm. Its channel-shaped profile surrounds the mating guide area and works with related wear strips, support plates and adjustment shims to maintain the required operating clearance.

Part number 446-1524 is widely cross-referenced in the replacement market to discontinued Cat part number 5T-8366. Because the published fitment ranges for the current and legacy numbers are not identical, final compatibility must be checked using the machine model, serial number, existing part number and component dimensions.
