D1146 DE08 Crankshaft 150107-00183A 65.02101-7024 65.02101-7025 for Doosan Engine Parts

Product Details

Product Overview

This high-precision crankshaft is engineered for Doosan D1146 and DE08 diesel engines, serving as a critical rotating component that converts linear piston motion into rotational power. Designed to meet OEM specifications, this part is a direct replacement for multiple cross-referenced numbers including 150107-00183A, 65.02101-7024, and 65.02101-7025.

Commonly utilized in heavy-duty applications such as excavators, trucks, forklifts, bulldozers, buses, and loaders, this crankshaft ensures reliable performance under demanding operating conditions. Manufactured with precision tolerances and heat-treated for durability, it is an ideal solution for engine rebuilds and replacement needs in construction, mining, and material handling equipment.

Key Features & Benefits

• OEM-Spec Dimensions: Manufactured to original equipment manufacturer (OEM) size standards, ensuring seamless fitment and installation compatibility with Doosan D1146 and DE08 engine blocks.
• High-Strength Material: Forged from premium alloy steel and subjected to heat treatment processes (nitriding or induction hardening) to enhance fatigue resistance and surface hardness for extended service life.
• Precision Machining: Journal surfaces are ground to tight tolerances (typically within 0.01mm) to minimize friction, reduce vibration, and maintain proper oil clearance for optimal lubrication.
• Balanced Rotation: Dynamic balancing is performed to reduce internal engine stress, minimize bearing wear, and ensure smooth operation at high RPMs.
• Rigorous Quality Control: Each unit undergoes dimensional inspection, hardness testing, and magnaflux crack detection to verify structural integrity before shipment.
• Direct Cross-Reference Compatibility: Replaces multiple OEM part numbers (150107-00183A, 65.02101-7024, 65.02101-7025), simplifying inventory management for workshops and distributors.

Technical Specifications

OEM Cross-Reference

This crankshaft is a direct replacement for the following original equipment manufacturer (OEM) numbers:

• 150107-00183A – Primary OEM number for Doosan/ Daewoo applications
• 65.02101-7024 – Alternative OEM cross-reference
• 65.02101-7025 – Alternative OEM cross-reference

Note: Always verify the exact crankshaft configuration (stroke length, main journal diameter, and flange pattern) against your specific engine serial number to confirm 100% compatibility.

Compatibility

This product is commonly used for the following engine models and equipment types:

• Engine Models: Doosan D1146, Doosan DE08
• Vehicle Applications: Excavators, trucks, forklifts, bulldozers, buses, loaders, and other heavy machinery powered by these diesel engines.

This part is designed for industrial and commercial off-highway equipment. For wheeled vehicle applications (trucks/buses), verify bell housing and flywheel compatibility.

FAQ

Q1: How do I confirm this crankshaft fits my Doosan D1146 engine?
A: Verify your engine serial number and measure the existing crankshaft’s main journal diameter (typically 90-110mm for D1146 series), stroke length (135mm for DE08), and rear flange bolt pattern. Cross-reference your current part number with 150107-00183A, 65.02101-7024, or 65.02101-7025 stamped on the old crankshaft. For further verification, request our dimensional drawing.

Q2: What is the recommended installation procedure for this crankshaft?
A: Professional installation is strongly recommended. Key steps include: (1) Thoroughly clean the engine block and oil passages; (2) Check main bearing clearance using plastigage (target: 0.06-0.12mm for used bearings, 0.04-0.08mm for new); (3) Apply assembly lube to all journal surfaces; (4) Torque main bearing cap bolts to the engine manufacturer’s specifications (typically 200-260 Nm for D1146); (5) Verify crankshaft end float (0.10-0.30mm). Always replace main bearings and thrust washers during installation.

Q3: What maintenance is required to maximize crankshaft service life?
A: Use high-quality diesel engine oil meeting API CI-4 or CK-4 specifications with the correct viscosity (SAE 15W-40 for most climates). Change oil and filter at intervals not exceeding 250 hours for heavy equipment. Monitor engine oil pressure regularly – a drop of 10% from normal baseline may indicate bearing wear. Avoid sustained operation at maximum rated RPM and never exceed the engine’s governed speed. If vibration develops after installation, immediately inspect flywheel and damper balance.
