When selecting Rexroth A8VO160 hydraulic pump parts for CAT Diesel 330, 330B, 345B, 345BL, and 345BLC models, focus on compatibility, working condition match, and manufacturing precision.

1. Key Selection Guidelines:

• Confirm Pump Model: Ensure the installed main pump is A8VO160; mismatched models may lead to efficiency loss or failure.

• Check Part Numbers: Verify compatibility using reference codes (e.g., Piston 5I-8401, Valve Plate 5I-4476, Shaft 5I-4475).

• Match Working Conditions: Choose components with proper material hardness and pressure resistance for mining, construction, or drilling sites.

• Avoid Low-Quality Parts: Poor aftermarket parts can cause pressure instability, piston cracks, or premature wear. OEM or precision aftermarket parts are strongly recommended.

• Focus on High-Wear Components: Pay special attention to piston sets, barrel, valve plates, shafts, and control springs.

2. Recommended Parts for Replacement:

• Piston Set

• Valve Plate (Left/Right)

• Drive Shaft

• Center Pin

• Retainer Plate

• Spring

• Gear

3. Selection Priority Suggestion:

OEM > High-Precision Aftermarket > Standard Aftermarket

Choose nitrided or quenched components with high machining accuracy for durability close to OEM standards but at lower cost.
