DE08 Main Bearing and Connecting Rod Bearing 0.25mm Oversize for Doosan Engine Parts

Product Details

Product Overview

This high-precision engine bearing set is specifically designed for the Doosan DE08 diesel engine, a powerplant commonly found in heavy construction and industrial equipment. The set includes both Main Bearings and Connecting Rod Bearings in a 0.25mm oversize (0.25) specification, which is typically required during engine rebuilds when the crankshaft has been ground to the first undersize.

Manufactured to match OEM size and tolerances, these bearings are suitable for a wide range of applications including excavators, trucks, forklifts, bulldozers, buses, and loaders. As a critical component for engine overhaul, this bearing set ensures proper oil clearance and load distribution, helping to restore engine performance and extend service life.

FAQ

Q1: Is this bearing set suitable for a Doosan DE08 engine that has not been reground?
This set is specifically a 0.25mm oversize bearing. It is intended for engines where the crankshaft has been ground down by 0.25mm. For a standard (non-reground) crankshaft, you would need standard size bearings. Always measure your crankshaft journal diameters to confirm the correct bearing size before ordering.

Q2: What is included in the set – how many main bearings and rod bearings?
This product includes both the complete set of main bearings and connecting rod bearings for the Doosan DE08 engine. The exact quantity matches the original engine configuration (typically 7 main bearings and 6 rod bearings for a 6-cylinder engine). Please verify your engine’s specific bearing count if you have a modified or special configuration.

Q3: How should I install these bearings to ensure proper oil clearance?
Proper installation requires clean hands and a clean work environment. Apply a thin layer of clean engine oil to the bearing surfaces before installation. Use Plastigage to verify oil clearance during assembly – typical clearance for DE08 main bearings is 0.06-0.12mm. Torque all bearing cap bolts to the manufacturer’s specifications using a calibrated torque wrench. Always install new bearings with a freshly reground or polished crankshaft for best results.
