Description
SBS140 215-7006 Hydraulic Pump Assembly Overview
The SBS140 215-7006 Hydraulic Pump Assembly manufactured by Tatan is a tandem variable displacement axial piston main pump belonging to our Hydraulic Pump Assembly classification. Engineered specifically for Caterpillar 330C, 330C L, and 330C LN 30-to-35 ton excavators, replacing your worn hydraulic pump with this complete SBS140 215-7006 Hydraulic Pump Assembly unit eliminates sluggish actuator response, high-temperature fluid degradation, and engine stalling under digging loads.
Constructed strictly to Caterpillar OEM standards, this unit houses dual 140 cc/rev rotating groups, high-density spheroidal iron cylinder blocks, and precision-ground swashplates. Factory pre-dressed with negative flow control (NFC) and cross-sensing constant power regulators, it delivers an exact match for Cat C9 engine torque curves and KMX32N main control valve banks.

SBS140 215-7006 Hydraulic Pump OEM Diagnostic Guide
Use this technical diagnostic guide to identify main hydraulic pump failures on your Caterpillar 330C excavator:
| Hydraulic Symptom | Technical Cause Analysis | Tatan Factory-Grade Solution |
|---|---|---|
| 1. Sluggish cycle times & weak bucket breakout force | Excessive internal slippage between bronze-faced valve plates and cylinder barrels, reducing working pressure below 25 MPa. | Replace with a complete pre-tested SBS140 215-7006 Hydraulic Pump Assembly. |
| 2. Cat C9 engine bogs down or stalls under heavy digging | Cross-sensing power regulator spool stuck or out of calibration, failing to destroke swashplate angle as working pressure spikes. | Calibrate power control springs, flush pilot circuits, or swap to a pre-adjusted complete pump unit. |
| 3. High-pitched whining noise & pump case vibration | Inlet suction line restriction, dirty tank strainer, or aeration from deteriorated input shaft oil seals causing severe cavitation. | Clean suction strainers, replace return filters, prime the pump casing, and install a brand-new pump unit. |
| 4. Hydraulic oil temperature spikes (>85°C) during light grading | Continuous high-pressure fluid bypassing worn piston slipper pads back to case-drain, generating severe friction heat. | Inspect case-drain flow rates, flush oil cooler passages, and install a new factory-sealed pump assembly. |
