Caterpillar Grader

Spacer-6G-5548

PRODUCT DESCRIPTION:

1. Precise Positioning & Alignment: Serves as a critical positioning component in the grader’s transmission, axle, or drawbar-circle assembly, ensuring accurate alignment of rotating shafts, gears, and bearing assembliesCat.

2. Clearance & Gap Control: Maintains consistent axial/radial clearances between mating components, preventing excessive play, friction, or misalignment during high-load operation.

3. Load Distribution: Distributes mechanical stress evenly across connected parts, absorbing vibration and shock loads generated during grading operations.

4. Wear Resistance & Protection: Acts as a sacrificial or protective layer, reducing direct metal-to-metal contact and extending the service life of expensive core components (e.g., gears, bearings).

Key Advantages

1. OEM-Grade Precision: Manufactured to Caterpillar’s original engineering specifications, guaranteeing perfect fit, dimensional accuracy, and compatibility with CAT 120/12 grader systems.

2. Superior Material Durability: Forged from high-strength alloy steel with precision heat treatment, delivering exceptional resistance to wear, fatigue, and impact under heavy-duty working conditions.

3. Enhanced Operational Stability: Minimizes component movement and vibration, improving the grader’s overall stability, blade control accuracy, and grading qualityCat.

4. Reduced Maintenance Costs: Prevents premature wear of critical drivetrain parts, lowering repair frequency, downtime, and long-term ownership costsCat.

5. Easy Installation: Designed for direct replacement, requiring no modifications—simplifies maintenance and ensures quick, reliable field service.

Application Notes

· Exclusively designed for use in the drivetrain, axle, or circle-drawbar systems of CAT 120 and 12 series motor graders.

· Recommended for use with genuine CAT lubricants and seals to maximize performance and service life.

· Critical for restoring factory clearances during rebuilds or repairs, ensuring optimal power transmission and operational efficiency.
