Identify the Pump Model

The CAT 12G Motor Grader typically uses a specific piston pump model. Check the pump’s identification plate or consult the equipment manual to confirm the exact pump model and serial number.

Repair Kit Components

Hydraulic pump repair kits for piston pumps usually include:

Seals (O-rings, gaskets, etc.)

Piston shoes

Valve plates

Springs

Bearings (if applicable)

Other wear components specific to the pump model

Function of the repair kit

Restore performance: After long-term use, the various components of the main pump of the Caterpillar 12G grader may experience wear and aging, resulting in reduced pump performance, such as insufficient flow, unstable pressure, leakage, etc. Using the repair kit to rebuild the main pump can replace severely worn parts, restore the main pump to its original performance level, and ensure the normal operation of the grader.

Extend service life: By replacing damaged parts, the wear and leakage inside the main pump are reduced, and the workload of the pump is reduced, which can extend the service life of the main pump, reduce the maintenance frequency and downtime of the equipment, and improve the efficiency of the equipment.

Save costs: Compared with directly replacing the entire main pump, rebuilding with a repair kit can greatly save costs. The components in the repair kit are usually high-quality products that have been strictly screened and tested. Their performance and reliability can meet the requirements of the equipment, and the price is relatively low.

Precautions for choosing a repair kit

Quality certification: Choose a repair kit with quality certification, such as ISO 9001, etc., to ensure that the components in the kit meet relevant standards and requirements and are of reliable quality.

Compatibility: Make sure the repair kit is fully compatible with the main pump of the Caterpillar 12G motor grader, including the size, specifications, and models of the parts, so as to avoid the situation where it cannot be installed or cannot work properly.

Brand and supplier: Choose a well-known brand and a reliable supplier to ensure the quality and after-sales service of the repair kit. You can refer to the comments and suggestions of other users and choose a reputable supplier.
