Motor Grader Grease and Lube Guide: 8 Points You Are Missing Every Week

A proper motor grader grease and lube guide starts with understanding why grease matters. Grease reduces friction between moving parts. Friction generates heat, wears metal surfaces, and creates play. Play causes poor grade control and eventually leads to complete component failure.

The motor grader grease and lube guide prevents this chain of events. A few minutes of greasing saves thousands of dollars in emergency repairs and ensures your machine performs accurately.

The first point in this motor grader grease and lube guide is the circle and drawbar. The circle rotates the blade, while the drawbar connects the circle to the frame. These components carry heavy loads and move constantly during operation.

The motor grader grease and lube guide recommends greasing the circle every 10 hours of operation. Most operators mistakenly grease the circle weekly. Locate the 4 to 8 grease fittings on top of the circle, attach the grease gun, and pump until grease pushes out of the joint.

A contractor ignored circle greasing for 2 weeks, leading to metal-to-metal contact that scored the circle surface. The repair cost $8,000. Following the motor grader grease and lube guide would have prevented this failure completely for just $2 worth of grease.

The second point in this motor grader grease and lube guide is the articulation joint. This joint bends the machine in the middle, allowing sharp turns and absorbing shocks from rough ground.

One operator noticed his grader wandering heavily on straight roads. The motor grader grease and lube guide check found a dry articulation joint that had not been greased in 300 hours. The operator added grease, and the wandering stopped immediately, saving both tire wear and fuel consumption.

The third point in this motor grader grease and lube guide is the blade lift cylinders. These cylinders raise and lower the blade. The cylinder pins pivot during operation and desperately need grease every 10 hours.

A highway contractor experienced severe blade bounce during fine grading. The motor grader grease and lube guide inspection found dry cylinder pins worn completely oval. The repair cost $1,200. Daily greasing would have easily prevented this wear.

The fourth point in this motor grader grease and lube guide is the blade sideshift mechanism. The blade slides left and right on the circle, and these slides must be greased every 10 hours.

Dry slides wear unevenly, causing uncontrollable blade drift. When operators must correct blade drift constantly, they waste immense time. Following the motor grader grease and lube guide prevents this drift and extends slide life by thousands of hours.

The fifth point in this motor grader grease and lube guide is the wheel lean mechanism. Wheel lean tilts the front wheels to help the machine hold grade on steep slopes.

A slope grading job took 2 extra hours because the wheel lean function was stuck. The motor grader grease and lube guide check found dry pivots. Greasing them restored the function instantly, preventing further fuel waste.

The sixth point in this motor grader grease and lube guide is the steering linkage. The linkage has multiple pivot points on the drag link and tie rod ends. They must be greased every 50 hours.

Dry steering linkages develop play, making steering loose and inaccurate. Precise steering is critical for fine grading alongside curbs. To complement your perfectly graded roads, roll the asphalt tight using the Typhon Fury 1.5 Ton Vibratory Compactor.

The seventh point in this motor grader grease and lube guide is the rear tandems. The rear tandem pivots allow the wheels to follow uneven ground while carrying incredibly heavy loads.

Dry tandem pivots seize and cause massive tire scrub. A fleet replaced rear tires at 800 hours instead of 2,000 hours because of this exact issue, losing $4,000 per machine. Routine maintenance prevents this costly damage.

The eighth point in this motor grader grease and lube guide is the ripper attachment. The ripper frame and cylinder pins need grease every 10 hours of active use.

Dry ripper pins wear quickly, causing loose shanks that snap under pressure. Replacing a broken shank costs $500, a fate easily avoided with proper lubrication.

Now let us apply this motor grader grease and lube guide to your daily routine. Start with the circle, drawbar, articulation joint, blade lift cylinders, and sideshift slides every single shift.

The motor grader grease and lube guide requires the correct grease type:

• Lithium Complex Grease: For most applications handling high loads and temperatures.
• Molybdenum Disulfide Grease: For the circle and drawbar to protect sliding surfaces.
• High-Temperature Grease: For wheel lean and steering pivots exposed to brake heat.

If you spot persistent fluid leaks while greasing, consult our motor grader fuel system troubleshooting guide to ensure your engine is not compromised.

One contractor implemented this motor grader grease and lube guide across 10 graders. Component failures dropped by 50 percent, and repair costs dropped by $35,000 per year.

Your motor grader grease and lube guide is your best defense against wear. Use it to train your operators, show them fitting locations, and explain exactly what happens when points run dry.

Your motor grader grease and lube guide is complete for today. Repeat this routine every shift. Your machine, repair budget, and project schedule will thank you.
