The spare parts of CAT416 hydraulic pump usually include the following main parts:

Repair Kit：Includes seals, O-rings, gaskets, and other wear components.Example part numbers:

350-0666 Repair Kit (specific to this pump model)

1W-0754 (example, verify compatibility)

Piston Shoes：These are critical components that wear out over time and need replacement during repairs.

Valve Plates：The valve plate controls the flow of hydraulic fluid and is a common replacement part.

Bearings：High-quality bearings ensure smooth operation and reduce friction.

Seals and O-Rings：Vital for preventing leaks and maintaining hydraulic pressure.

Shafts and Springs：These components are essential for the proper functioning of the pump.

Cylinder Blocks：The cylinder block houses the pistons and is a key part of the pump assembly.

Swash Plates：The swash plate controls the piston stroke and is a critical part of the pump.

Function of the kit

Restore performance: Replace worn or damaged parts to restore the CAT 350-0666 02 piston pump to its original performance level, ensuring the normal operation of the hydraulic system of the CAT416E equipment, such as lifting force, steering force and other operations.

Extend life: New parts can reduce wear and leakage inside the pump, reduce workload, extend the service life of the piston pump and the entire hydraulic system, and reduce equipment maintenance frequency and downtime.

Save costs: Compared with replacing the entire hydraulic pump, using a repair kit is less expensive and can make full use of the original pump’s usable parts, which has a higher cost-effectiveness.

Related products and features on the market

Original repair kits: produced or authorized by Caterpillar, fully meet the design requirements and quality standards of CAT416E hydraulic pumps, high performance and reliability, but relatively high prices.

Third-party high-quality repair kits: Repair kits provided by some professional hydraulic parts manufacturers, reliable quality, performance close to or reaching the original level, more advantageous prices, good compatibility and cost-effectiveness, but be careful to choose brands with quality assurance and reputation.
