Product Introduction
This comprehensive spare parts catalog features direct-fit OEM replacement components for routine preventive maintenance, partial repairs, and full overhauls of the WB-4677006 shaker and 3400 centrifuge, covering all high-failure-rate critical parts: angular contact/roller/ball bearings, socket head cap screws, gearbox adaptors, feed cones, spline bushings, stabilizer inserts, O-rings, gaskets, grease nipples, and torque control assemblies. Unlike generic aftermarket alternatives, each component is built to the original WB-4677006 and 3400 centrifuge design specifications, material grades, and dimensional tolerances, ensuring seamless on-rig installation, zero compatibility errors, and reliable performance under the harsh conditions of drilling solids-control operations.
Functional Specifications
- Bearing Assemblies: Precision angular contact, roller, and ball bearings support high-speed rotating shafts, reducing friction and heat buildup to withstand continuous shaker/centrifuge vibration and heavy radial loads.
- Sealing & Containment Parts: Industrial-grade O-rings (BS 3393-57, 179.3MM x 5.7MM) and case gaskets create leak-proof seals, preventing drilling fluid loss and blocking mud contamination of internal bearings and gears.
- Fastening Hardware: Metric socket head cap screws (M6/M8/M10) and set screws provide vibration-resistant clamping, keeping shaker/centrifuge components tightly secured during high-speed operation.
- Power & Alignment Components: Spline bushings ensure smooth power transfer from drive systems to rotating assemblies; gearbox adaptors and feed cones optimize fluid flow and centrifuge feeding efficiency.
- Maintenance & Control Parts: 1/8″ BSPT straight grease nipples enable reliable lubrication of bearing points; torque control assemblies regulate operating torque to prevent overloading and component damage.
Structural Characteristics
All WB-4677006 shaker and 3400 centrifuge spare parts feature rugged, oilfield-specific construction for maximum durability: bearings use high-carbon chrome steel for superior load capacity and wear resistance; seals use nitrile-based elastomers resistant to drilling mud and oil; fasteners use corrosion-resistant coated steel to prevent rust and vibration loosening; bushings and adaptors use precision-machined forged steel for tight dimensional accuracy. Components are designed for tool-friendly field installation, minimizing repair time during critical drilling shifts and reducing labor costs for remote rig maintenance.
Applicable Operating Conditions
These spare parts are engineered to perform reliably in the extreme conditions of WB-4677006 shaker and 3400 centrifuge operation, including:
- 24/7 continuous solids-control processing of drilling mud and waste fluids
- Exposure to abrasive drilling mud, rock cuttings, oil, and high-humidity rig environments
- Extreme cyclic vibration (up to 15G force) from shaker/centrifuge rotation
- Ambient temperatures ranging from -15°C (5°F) to 70°C (158°F) across global drilling locations
- Compliance with API 13C solids-control equipment standards and heavy-duty industrial durability requirements
Maintenance & Servicing Recommendations
- Pre-Installation Verification: Cross-reference OEM part numbers against WB-4677006 and 3400 centrifuge technical manuals to confirm exact fitment; inspect parts for defects and clean all mating surfaces to remove mud, grease, and debris before assembly.
- Bearing & Lubrication Care: Lubricate bearings via grease nipples every 1,000 operating hours with approved drilling-grade grease; replace worn bearings immediately if noise, vibration, or play is detected to prevent catastrophic failure.
- Seal & Gasket Maintenance: Replace O-rings and case gaskets during every major repair; lubricate seal lips lightly during installation to prevent tearing; check for fluid leaks post-repair and retorque fasteners to OEM torque specifications.
- Fastener & Bushing Checks: Re-torque all socket head cap screws and set screws every 1,500 hours to combat vibration loosening; inspect spline bushings for wear and replace if power transfer is inconsistent.
- Torque Control Calibration: Test torque control assemblies quarterly for proper operation; adjust settings to match shaker/centrifuge load requirements and replace faulty assemblies to prevent overloading damage.

On-Rig Shaker & Centrifuge Fault Repair Cases
Case 1: Bearing Failure & Centrifuge Shutdown
A 3400 centrifuge paired with a WB-4677006 shaker suffered a sudden shutdown due to a seized angular contact bearing (001-012-716), caused by mud contamination and lack of lubrication. The bearing failure halted solids processing and delayed drilling operations. Installing a new OEM bearing and replacing the surrounding O-rings restored smooth rotation and full centrifuge efficiency.
Case 2: Fluid Leak & Mud Contamination
Excessive drilling fluid leakage from the centrifuge case occurred due to a degraded case gasket (034-036-000) and worn O-rings, leading to fluid loss and bearing contamination. The leak reduced separation efficiency and risked further internal damage. Replacing the gasket and O-rings, then resealing the case, eliminated leaks and protected internal components.
Case 3: Loose Fasteners & Component Misalignment
The WB-4677006 shaker developed abnormal vibration and noise, traced to loose M10 socket head cap screws (001-201-1007) that caused end plate misalignment. The misalignment disrupted rotation and risked bearing damage. Retorquing the fasteners and replacing worn set screws restored proper component alignment and reduced vibration.
