Hydraulic sealing system parts for motor graders seal kits

Motor graders machine using a scraper to level the ground. The scraper is installed between the front and rear wheel axles of the machine, which can lift, tilt, rotate and extend. Flexible and accurate movements, easy to operate, high leveling accuracy, suitable for subgrade and pavement construction, slope construction, excavation of side ditch, can also mix road surface mixtures, remove snow, push loose materials, and carry out soil roads and roads. Maintenance work on gravel road.

Graders are the main machinery used in shaping and leveling operations in earthworks, and are widely used in road and airport large-scale ground leveling operations. The reason why the grader has a wide range of auxiliary operations is that its scraper can complete 6 degrees of motion in space. They can be performed individually or in combination. The grader can provide sufficient strength and stability for the roadbed during the construction of the roadbed. Its main methods in subgrade construction include leveling operations, brushing operations, and embankment filling. The grader is a high-speed, high-efficiency, high-precision and multi-purpose Motor grader engineering machine. It can complete the large-scale ground leveling and trenching, slope scraping, bulldozing, snow removal, loosening, compaction, distribution, mixing, assisting and land reclamation of important areas such as highways and farmland. It is an important equipment in national defense projects, mine construction, road construction, water conservancy construction, and farmland improvement. Highway subgrade is the foundation of pavement and an important part of highway engineering. The subgrade bears the traffic load from the road surface and is a supporting structure of the road surface. It must have sufficient strength, stability and durability. Depending on the terrain, highway subgrades generally take the form of embankments and coffers.

Motor Grader structural features

The development and expansion of grader products not only need to meet the working adaptability of different working conditions, but also must maintain the maximum part commonality (or interchangeability) with the basic model, which brings the majority of users with maintenance. Great convenience. The crawler grader is mainly composed of engine, transmission system, working equipment, electrical parts, cab and hood. Among them, the mechanical and hydraulic transmission systems include torque converters, coupling assemblies, planetary gear-type power shift transmissions, central transmissions, steering clutches and steering brakes, final transmissions, and travel systems. The power output mechanism drives the working pump, variable-speed torque-variable hydraulic system variable-speed pump, and steering brake hydraulic system steering pump in the hydraulic system of the working device by means of gear transmission and spline connection; the sprocket represents the final transmission mechanism of the two-stage spur gear transmission (Including left and right final drive assemblies); track system including track assembly, trolley frame and suspension assembly.

For MOTOR GRADERS seal kits, there are BLADE LIFT, BLADE SHIFT, DRAWBAR, SHIFT FRONT BALDE, LEANING, POWER TILT, STEERING RIPPER, ARTICULLATE, SCARIFIER 

Different types of motor graders have different cylinders and different function of motor grader, and different cylinder may allocate in the same model of motor grader, mining grader;therefore we kindly advise you to provide the brand; model;140 grader; part; part no.of the machines; the most important one is the part no. of the part that you want, we will follow the OEM part no. Manual to check for you to fit your motor graders to meet your motor grader function. 

If you do not have part no., you could send the ROD diameter and BORE diameter to double check with the drawing as following.

For MOTOR GRADERS, the brand that we have as following: KOMATSU, CATERPILLAR, SDLG.
