Description
The ARP 250-5802 main stud kit is listed for Ford 6.7L Powerstroke Diesel. It secures the main bearing caps to the cylinder block, making fastener choice part of the bearing-clearance and machining plan for the engine build.
Technical Highlights
- Manufacturer part number: 250-5802
- Application/configuration: Ford 6.7L Powerstroke Diesel
- Material: ARP2000
ARP2000 is an alloy steel that can be heat treated to a higher strength level than 8740. This material choice does not establish a horsepower limit; fastener selection must also account for the application and required preload.
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.
