FAQ

Q: How do I confirm this bearing set fits my specific engine?
A: This set is specifically designed for the Mitsubishi 4DQ5-2 diesel engine. To ensure compatibility, please check your engine model number (located on the engine nameplate) and verify it matches “4DQ5-2”. Additionally, confirm that your engine requires standard OEM-size bearings. If your engine has been previously rebored or requires oversized bearings, this standard set may not be suitable.

Q: What is the recommended installation procedure for these bearings?
A: Installation should be performed by a qualified diesel mechanic following the engine manufacturer’s service manual. Key steps include: cleaning bearing surfaces thoroughly, checking oil clearance using Plastigage, applying clean engine oil to bearing surfaces during assembly, and torquing main bearing and connecting rod bolts to factory specifications. Always replace bearings as a complete set and never mix old and new components.

Q: How should I store these bearings before installation?
A: Store bearings in a clean, dry environment at room temperature. Keep them in their original packaging until ready for installation to prevent contamination from dust, moisture, or debris. Avoid exposure to extreme temperatures or direct sunlight. Handle bearings with clean hands or gloves, as skin oils can attract contaminants that may affect bearing performance.
