Multiquip 513315 Cover Rear Water Tank AR-13H - OEM Replacement Part

The rear water tank cover protects and seals the water ballast system on Multiquip AR-13 series ride-on tandem drum rollers. This cover is essential for maintaining proper water containment in the rear drum, which increases operating weight from 3,360 lbs to 3,437 lbs when filled for enhanced compaction performance on asphalt and granular soils.

The water tank system works in conjunction with the rear spray control valve to provide gravity-fed water distribution to the rear spray bar during asphalt paving operations. Daily inspection of water tank level is required per the AR-13 maintenance schedule. A compromised or missing tank cover can lead to water loss, contamination of the ballast system, and reduced roller operating weight, which directly impacts compaction efficiency and centrifugal force delivery of 3,100 lbs at 2,400-2,700 rpm.

This rear tank cover is specifically engineered for the AR-13H model configuration and related variants in the AR-13 series roller line.
