SINOTRUK HOWO Arc Gear Oil Pump / Fuel Bowser Pump 30 m³/h 65YCB-30F ES99803060006
Common Faults and Maintenance Recommendations
1. Oil leakage at the input shaft or end cover: Prolonged high-load rotation causes wear on the shaft seal at the front end, allowing oil to drip out along the shaft end.
2. Insufficient flow / Failure to pump oil:
Mechanical causes: If the pumped medium contains sand or impurities, the curved surfaces of the gears and the inner walls of the pump housing may suffer mechanical scoring; increased clearances lead to internal leakage and a significant drop in flow rate.
Cavitation and air lock: Poor sealing in the intake line or a clogged intake filter.
3. Routine replacement and installation tips:
Before installing a new pump, thoroughly inspect and clean the intake line filter.
When connecting via a Power Take-Off (PTO) drive shaft, ensure proper coaxial alignment; misalignment or eccentricity will cause severe vibration during high-speed operation, rapidly shattering the pump bearings.

| No. | OEM Part Number | Component Name (English) | Recommended Qty | Maintenance & Procurement Recommendation |
|---|---|---|---|---|
| 1 | ES99803060006 | Arc Gear Oil Pump Assembly (65YCB-30F) | 1 pc | Core Faulty Assembly. Contains the high-toughness cast iron housing, a pair of precision arc gears, and the input shaft end. |
| 2 | 65YCB-F01 | Inlet / Outlet Flange Oil-Resistant Gasket | 2 pcs | Mandatory Replacement. Must use oil-and-fuel-resistant asbestos or fluororubber (Viton) material to handle diesel, gasoline, or lube oil. |
| 3 | GB/T 9877 | Front Shaft Skeleton Oil Seal | 1 pc | Wear Component. Located at the drive input shaft head. Replace this individual item if the original pump only exhibits shaft-head weeping without internal wear. |
| 4 | GB/T 276 | Input Shaft Bearing (Deep Groove Ball / Cylindrical Roller) | 2 pcs | Mandatory for Overhauls. Supports high-speed gear rotation. Must be pressed out and replaced if any gritty sensation or excessive play is detected. |
| 5 | PTO-UJ01 | PTO Drive Shaft Universal Joint Cross | 1-2 pcs | Linked System Inspection. This pump is typically driven by a Power Take-Off (PTO) via a drive shaft. A worn or binding U-joint causes severe vibration and ruins the new pump. |
