Komatsu wing shroud 427-70-13610/K3814HX/21T-70-34221

Our aftermarket replacement Komatsu Sidebar Protector/Caterpillar Sidebar Shroud/wing shroud/bucket tooth guard is a heavy-duty pin-mounted vertical wear protection part designed exclusively for Caterpillar wheel loader and excavator bucket sidebar structures. Different from bolt-on flat side cutters that protect only the outer edge, our pin-on sidebar covers the vertical high-wear sidebar zone of the bucket, which endures continuous side friction, material washout, lateral impact and rock gouging during loading, grading and stockpiling operations.
Our aftermarket Komatsu sidebar shroud /wing shroud/bucket tooth guard can solve below headache issues :
1. Eliminates vertical sidebar washout and grooving wear that side cutters cannot solve.a
2. Pin-lock structure avoids bolt loosening and falling off during heavy vibration.
3. Preserves bucket side geometry, maintains stable digging penetration and production efficiency.
4. Replaceable pin-on protector avoids expensive sidebar cutting and rebuilding.
5. Reduces fleet maintenance downtime and long-term bucket operating costs.
