345-3548 FLY WHEEL SIDE

345-3548 FLY WHEEL SIDE CATERPILLAR

The 345-3548 Fly Wheel Side Caterpillar is a critical component engineered for robust performance in heavy-duty Caterpillar machinery. This flywheel side cover functions as a structural and protective element for the flywheel and transmission interface, contributing significantly to machine efficiency, reliability, and operational lifespan. Built to withstand harsh working conditions, this part ensures precise alignment and seamless torque transfer in rock drilling and excavation applications.

Technical Specifications:

• Part Number: 345-3548

• Product Type: Flywheel Side Cover

• Material: High-strength, industrial-grade polymer composite

• Mount Type: 8-bolt evenly spaced flange

• Interface: Internal spline fitting with reinforced core structure

• Color: Matte black

• Weight Class: Lightweight for easy installation

• Outer Diameter: ~260mm
