Perkins T401471 Crankshaft for 2806 Series Diesel Engine

The Perkins T401471 crankshaft is a crankshaft replacement component for Perkins 2800 Series diesel engine applications and related high-power diesel engine applications. It is commonly used in Perkins 2806 series engines for industrial generator sets, mining equipment, heavy construction machinery and oil & gas field power systems.

As the core rotating component of the engine, the crankshaft converts the linear motion of the pistons into rotational power. In high-load applications such as mining equipment and continuous power generation systems, the crankshaft must withstand torque fluctuation, heavy mechanical stress and long operating hours.

Before quotation, ZEB Power helps confirm the part number, engine model, engine serial number and overhaul requirements to reduce the risk of wrong supply.

Key Product Information

Compatibility may vary depending on engine arrangement, serial number and original crankshaft part number. Final matching should be confirmed by engine nameplate, old part number or actual crankshaft photos before ordering.

Product Overview

The crankshaft is one of the most critical components inside a Perkins diesel engine. It receives force from the connecting rods, converts piston movement into rotational output and transfers power to the flywheel and driven equipment.

For Perkins 2806 series engines used in generator sets, mining excavators and heavy-duty equipment, crankshaft reliability directly affects engine balance, oil clearance, bearing life and long-term operating stability. A damaged or incorrectly matched crankshaft may lead to repeated bearing failure, abnormal vibration, low oil pressure or complete engine shutdown.

When replacing the Perkins T401471 crankshaft, it is recommended to inspect related components such as main bearings, big end bearings, connecting rods, piston kits, cylinder liners and oil pump condition at the same time.

Compatible Engine Applications

The Perkins T401471 crankshaft is commonly used for high-power Perkins 2800 Series engine applications, including:

• Perkins 2806A-E18TAG2
• Perkins 2806A-E18TAG3
• Perkins 2806C-E18TAG3
• Perkins 2806D-E18TA
• Perkins 2806A/D-E18TAG1(A)
• Related Perkins 2500 Series engine applications

These engines are widely used in industrial generator sets, mining equipment, heavy construction machinery and oil & gas field power systems where stable torque output and continuous engine operation are required.

Common Reasons for Crankshaft Replacement

In heavy-duty applications, crankshafts operate under high load, repeated torque impact and continuous mechanical stress. During long-term operation or after major engine failure, crankshaft replacement may become necessary.

Severe Crankshaft Journal Wear

After long operating hours, crankshaft journals may become worn due to friction with main bearings and connecting rod bearings. Excessive wear can affect oil clearance, bearing contact and engine stability, making replacement necessary during engine overhaul.

Main Bearing Failure or Engine Seizure

If main bearings fail or lubrication problems occur, the crankshaft journals may become scored, overheated or damaged. In severe cases, bearing seizure can damage the crankshaft surface and require replacement.

Crankshaft Cracks or Structural Damage

Under extreme operating conditions such as mining, quarrying or continuous generator operation, the crankshaft may develop fatigue cracks or structural damage over time. Once cracks are detected, replacing the crankshaft is usually the safer solution.

Major Engine Overhaul

During a complete overhaul of Perkins 2800 Series engines, the crankshaft should be inspected carefully. If wear, scoring, deformation or crack damage exceeds acceptable limits, replacing the crankshaft helps restore engine reliability and operating performance.

Real-World Application in Mining Equipment

In mining equipment applications, excavators and heavy equipment often work under demanding conditions such as hard rock excavation, continuous loading and high engine load. Engines used in these machines must deliver strong torque and stable power output to keep equipment operating efficiently.

For example, large mining excavators equipped with Perkins 2806D-E18TA engines rely on stable crankshaft performance to support heavy digging, loading and long-duty operation. The crankshaft must withstand repeated torque fluctuation while maintaining precise rotation at high engine speed.

A correctly matched Perkins crankshaft helps support smooth power transfer, reduce abnormal vibration and restore stable engine operation after overhaul.
