| No. | Component Name | OE / Manufacturer Part No. | Qty | Replacement Level | Remarks / Functional Description |
|---|---|---|---|---|---|
| I. Core Hydraulic Power Component (Inquired Items) | |||||
| 1 | Tandem Hydraulic Gear Pump Assembly | 803073887 / 1163134008I | 1 pc | Failure Replacement | This product; Permco original heavy-duty, high-pressure twin gear pump (main pump). |
| II. Drivetrain & Power Input Mechanism (Connection System) | |||||
| 2 | Power Take-Off Assembly (PTO) | Varies by chassis transmission specification | 1 pc | Inspect & Replace | The auxiliary gearbox driving the main pump; inspect for internal gear wear and backlash. |
| 3 | Drive Shaft Universal Joint (Cross Journal) | Specific crane drivetrain specification | 1 set | Highly Recommended | Connects the PTO to the pump input shaft. Play or binding causes severe shaft vibration, leading to premature oil seal failure. |
| III. Filtration & Contamination Control System (Must be replaced if old pump failed) | |||||
| 4 | Hydraulic Return Line Filter Element | 803164213 (Reference No.) | 2 pcs | Mandatory Overhaul | Filters all return line impurities. Metal debris from old pump scoring is trapped here; must be replaced to protect the new pump. |
| 5 | Hydraulic Suction Line Strainer / Filter | 803164522 (Reference No.) | 1 pc | Mandatory Overhaul | Located at the oil tank suction inlet; prevents larger raw contaminants from entering the new pump causing abrasion. |
| 6 | High-Pressure Flange O-Rings | High-pressure Fluororubber (Viton) O-Rings | 1 set | Mandatory | Dedicated high-pressure sealing rings for the pump inlet and outlet flanges. Do not reuse old ones. |
| IV. Hydraulic Fluids & Maintenance Consumables | |||||
| 7 | Anti-Wear Hydraulic Oil | Premium AW-46 or AW-68 Hydraulic Oil | A.R. | Mandatory | Depending on overall system oil contamination, perform a partial top-off (approx. 20–30L) or a complete fluid flush. |
