Thick 60mm Steel for Extreme Corner Wear Resistance

The Komatsu D475A End Bit 198-71-31520 / 198-71-31530 is manufactured from high-strength heat-treated steel. It is designed specifically for Komatsu D475A bulldozers. These end bits measure 60mm thick, providing exceptional wear material for the most demanding dozing conditions. The left-hand (198-71-31520) and right-hand (198-71-31530) designs ensure proper fitment on both blade corners. Consequently, they protect the moldboard edges from severe abrasion and impact. Additionally, the substantial thickness extends service intervals significantly. Therefore, these end bits are ideal for mining, quarrying, and large-scale earthmoving operations where corner wear is most aggressive.

Simple Installation for Both Blade Corners
Installing the Komatsu D475A End Bit is straightforward. Follow these steps:

Remove the worn end bit from the blade corner position.
Clean the mounting surface thoroughly to ensure proper fit.
Position the new end bit against the blade, matching the bolt holes.
Insert the appropriate plow bolts with hardened washers.
Torque all nuts evenly in a crossing pattern to manufacturer specifications.

For best results, follow these maintenance tips:

Check bolt tightness after the first few hours of operation.
Inspect both end bits regularly for uneven wear.
Replace when approximately 40% of the original thickness remains.
