Technical Highlights

• Manufacturer part number: 202-5406
• Application/configuration: Nissan L24 L26 L28 Series 6-Cylinder

Selection Guidance

The specified cap arrangement, block design and windage-tray requirements determine which kit is appropriate. A similar displacement or engine-family name does not establish that different main fastener kits are interchangeable.

Confirm the block, main-cap arrangement and any girdle or windage tray before ordering. Plan these checks before final machining and bearing selection.

Installation Considerations

Have the engine builder check main-bearing bore size and roundness with the intended fasteners installed at the specified preload. Align-hone if required, using the same hardware and lubricant intended for final assembly. Follow the kit-specific instructions for thread preparation, washer placement and tightening.
