Multiquip 28777-352 Frame Assembly SP2/C3 16"/18"/20" - OEM Replacement Part

This frame assembly provides the critical structural foundation for Multiquip self-propelled pavement saws, supporting the blade shaft bearing system, V-belt drive components, and blade guard mounting points for 16", 18", and 20" blade configurations. The frame houses the pillow block bearings that support the 1-1/4" blade shaft and includes mounting provisions for the four premium V-belts required for proper saw operation.

The frame assembly incorporates precision-machined mounting surfaces for the self-aligning blade shaft bearings, which are secured with four screws, flat washers, and lock washers per bearing location. The bayonet fitting system ensures proper blade guard seating, while integrated water hose channels route flood water to the blade cutting zone. This assembly is engineered to handle the demanding loads of professional concrete cutting applications while maintaining proper V-belt alignment and blade shaft support.

When replacing the frame assembly, factory technicians recommend inspecting and replacing both left and right pillow block bearings simultaneously, as bearing failure can compromise frame integrity and blade alignment. Compatible with multiple blade diameters, this frame assembly supports the full range of cutting depths required for professional pavement sawing operations.
