High-Precision Bucket Shaft Duo-Cone Seals for Heavy-Duty Excavation
When your machinery is operating in extreme environments, the integrity of your bucket shaft is paramount. The 174-4874 (also identified as 1744874) floating seal group is engineered to provide a hermetic barrier against mud, water, and abrasive particles. Paired with the 0931425 part number, these seals ensure your CAT equipment remains operational with minimal downtime.
Whether you are performing a routine overhaul or an emergency repair, choosing our OEM-standard replacement guarantees a perfect fit and long-lasting seal performance.
Why settle for low-grade seals when your CAT bucket shaft demands the best? Check our core procurement points below:
| Feature | Our 174-4874 / 0931425 OEM Standard | Common Aftermarket Seals |
|---|---|---|
| 1. Material Composition | High-alloy corrosion-resistant cast iron | Standard carbon steel (rust prone) |
| 2. Rubber Ring Tech | High-resilience Nitrile/Viton for thermal stability | Recycled rubber (cracks easily) |
| 3. Sealing Surface | Precision-lapped mirror finish for zero leakage | Rough grind finish |
| 4. Operating Life | Exceeds 5000+ working hours | Fails under 1500 hours |
| 5. Fit Accuracy | 100 percent match for 174-4874 and 1744874 | Loose tolerances causing vibration |
| 6. Pressure Resistance | High-pressure static and dynamic load capable | Prone to deformation under load |
| Model NO. | 174-4874 / 0931425 Excavator Series | Part Number | 174-4874 (1744874) |
| Product Name | Bucket Shaft Floating Seal / Duo-Cone Seal | Type | Mechanical Face Seal |
| Condition | Brand New, OEM Standard Replacement | MOQ | 1 Piece |
| Stock Status | In Stock / Fast Dispatch | Packaging | Industrial Export Packing |

If you notice oil misting around the bucket shaft or visible weeping of lubricant, it is time for an immediate inspection. Operating with a compromised 0931425 seal will lead to internal bearing contamination and catastrophic failure.
First, clean the area to identify the source. If the leak persists from the duo-cone interface, the seal has likely reached its wear limit or the rubber rings have lost elasticity. Replace with a new 1744874 unit immediately. Ensure the housing is free of debris before installation.
