Multiquip 515645 Chassis Front - OEM Replacement Part for Ride-On Rollers

The front chassis assembly serves as the primary structural framework for the front drum section of the ride-on roller, supporting critical components including the front drum assembly, hydraulic motors, and articulating steering mechanism. This welded steel chassis must maintain precise alignment and structural integrity to ensure proper compaction performance and operator safety during asphalt and granular soil applications.

On the AR13D ride-on tandem drum roller, the front chassis supports the 35.7-inch wide front drum (22.6-inch diameter, 0.38-inch thick steel) and maintains the 45-inch wheelbase critical for the machine's 109-inch inside turning radius. The chassis design accommodates the front sprinkler system gravity feed spray bar and provides mounting points for the articulating locking bar that connects to the rear frame section. With the complete roller operating at 3,360 lbs (1,524 kg), the front chassis must withstand significant dynamic loads, especially when the centrifugal force system generates 3,100 lbs of compaction force at 2,400-2,700 rpm.

Chassis damage or structural fatigue can result from impact damage, prolonged vibration exposure, or improper operation on extreme terrain. Regular inspection of welds, mounting points, and frame alignment is essential during scheduled maintenance intervals.
