Mounting kit included; the eight frame-mounting bolts and nuts are not included.
The Buyers Products UR35A 35-gallon upright aluminum hydraulic reservoir provides hydraulic oil storage in a narrow, behind-cab layout. Its aluminum construction helps reduce weight and dissipate heat, with a diamond-tread finish on the upper half of the tank.
Fully baffled construction supports oil circulation and cooling. A chrome filler breather and a combined oil-level/temperature sight gauge are included for filling and checking the reservoir. This upright configuration is used in truck and trailer hydraulic systems, including dump and walking-floor applications, when its capacity, connections and mounting arrangement meet the system requirements.
Upright storage with oil level and temperature checks
The shallow tank body helps fit hydraulic storage behind the cab. Include the mounting base and service access when checking available space: the body depth is 7.95 inches, while the base extends to 12 inches.
