Multiquip 518466240 Breather Oil Tank Cap - OEM Replacement Part

The oil tank breather cap allows pressure to escape to the air in the form of gas from heat, preventing dangerous pressure buildup in the hydraulic system during operation. This critical safety component protects the 5.8-gallon hydraulic oil tank from over-pressurization that could rupture seals, cause oil leaks, or lead to catastrophic system failure on vibratory roller equipment.

As noted in official Multiquip service documentation, operating the roller without proper breather function can cause the oil tank to build excessive pressure and severely scald personnel in the general area. The breather cap must be inspected regularly and replaced if damaged, clogged, or showing signs of wear. Technicians should always turn the engine off before performing maintenance and allow hot components to cool before servicing.

This breather cap is designed specifically for the hydraulic oil system, which uses Idemitsu Daphne Super Hydro 46A oil. Regular inspection of this component during routine maintenance intervals helps ensure safe operation and protects the integrity of the hydraulic system.
