DL08 Main Bearing and Connecting Rod Bearing 0.25 Size for Doosan Engine Parts Excavator Truck

Product Details

Product Overview

This product listing offers a complete set of Main Bearings and Connecting Rod Bearings specifically designed for the Doosan DL08 diesel engine. The bearings are supplied in a 0.25mm undersize (0.25) specification, which is a standard service size commonly used for engine rebuilds where the crankshaft has been ground down to remove wear or scoring.

These components are critical for maintaining proper oil clearance and supporting the rotating assembly within the engine block. Suitable for a wide range of heavy equipment applications including excavators, trucks, forklifts, bulldozers, buses, and loaders, these parts are manufactured to meet OEM size standards, ensuring a reliable fit for your Doosan engine overhaul project.

• Durable Construction: Built from high-quality materials designed to withstand the high pressures and temperatures of diesel engine operation, offering long service life.
• Comprehensive Set: Includes both main bearings and connecting rod bearings, providing everything needed for a full lower-end rebuild in one package.
• Cost-Effective Solution: Offers a competitive price advantage for B2B buyers, wholesalers, and repair shops looking for reliable engine parts without high OEM markups.
• Warranty Coverage: Comes with a 6-month warranty, providing peace of mind and quality assurance for your investment.

Technical Specifications

OEM Cross-Reference

While no specific OEM part number is provided in the source data, these bearings are designed to match the original Doosan specifications for the DL08 engine. They are intended to replace the standard factory main and rod bearings. Please verify your existing part number or crankshaft journal size before ordering. If you have a specific OEM number from your old bearings, please contact us to confirm compatibility.

Compatibility

This bearing set is specifically designed for the Doosan DL08 diesel engine. Due to the common use of this engine platform, these bearings are commonly used for rebuilding engines in the following equipment:

FAQ

Q: How do I know if I need a 0.25mm undersize bearing for my DL08 engine?
A: A 0.25mm undersize bearing is typically required when the crankshaft has been ground down to remove damage. You must measure the ground journal diameter with a micrometer. For a standard journal, this size is used after a 0.25mm grind. For non-ground crankshafts, use standard (STD) size bearings.

Q: Is this a complete set for one engine?
A: Yes, this listing includes both the main bearings and connecting rod bearings required for a complete lower-end rebuild of one Doosan DL08 engine. It includes all shells needed for the main journals and connecting rod journals.

Q: What is the installation procedure for these bearings?
A: Installation requires professional mechanical knowledge. The bearing shells must be cleanly installed into the cylinder block and connecting rods. Ensure the bearing tangs align with the grooves in the housing. Critical steps include torquing main cap and rod cap bolts to the manufacturer’s specifications and checking oil clearance with Plastigage. Always lubricate the bearings with clean engine oil during assembly.
