2009 Case 580n Bolt Sizes & Torque Specs

Lug nut torque is not verified for this summary. Review the cited evidence and exact hardware application before installation.

This page distinguishes source-backed fields, unresolved conflicts and unverified legacy records for the 2009 Case 580n. Match the exact hardware and manual conditions before maintenance. A source for one field does not verify the other specifications.

For the 2009 Case 580n, fasteners follow application-specific metric or SAE standards typical of mid-2000s Case engineering. Always confirm spec against the factory service manual before tightening safety-critical fasteners (suspension, brake, steering, head bolts).

Common fastener categories on the 2009 Case 580n

Wheel / lug nut torque and thread spec (covered above)
Brake caliper bracket, mounting, and slide/guide-pin bolts are different fasteners. Confirm the exact axle, application and service-manual specification before reassembly.
Engine oil drain plug torque and tool size when this vehicle has a verified drain-plug record
Transmission pan, valve cover, and intake manifold bolts where the database has exact records
Suspension control arm, sway bar, tie rod end and ball joint torque
Spark plug torque only when a vehicle-specific spark-plug row is available
Differential cover bolts (RWD/4WD only) and transfer case fasteners

Repair guidance for this model year

For 2009 model-year work: Always use a calibrated torque wrench for safety-critical fasteners, and replace lock washers and crush washers on every reassembly.

Tools you will need

Metric and SAE socket set (8mm-22mm plus 1/4"-7/8"), 6-point impact-rated
Calibrated torque wrench (10-150 ft-lbs covers most automotive jobs; add a 0-250 ft-lbs wrench for truck lug nuts)
Breaker bar (24" minimum) for initial loosening
Penetrating oil (PB Blaster or Kroil) for any fastener over 5 years old
Replacement washers, threadlocker, anti-seize, or dry-thread preparation only when the exact service procedure specifies them

Frequently asked questions

What is the lug nut torque on a 2009 Case 580n?

Specification not verified for this lug nut summary. Do not substitute another model year's value.

What socket size do I need for the 2009 Case 580n lug nuts?

Confirm the socket against the actual lug nut; no size is assumed here.

Are the 2009 Case 580n fasteners metric or SAE?

Metric and SAE hardware can both appear on one vehicle, depending on the component and exact application. Use the individually verified field and the actual fastener or service manual rather than inferring a standard from the model year, make or generation. Bolt-head markings can help identify the hardware at the bench.

Other Case 580n years

Same model, different model year — fastener spec may change. Always confirm against the year for your VIN.

7 recorded 2009 Case 580n fasteners

Every bolt we have on record for the 2009 Case 580n. A value marked verified names the document it came from. A verified torque doesn’t confirm the socket size, thread or part number, and a value that isn’t marked verified hasn’t been checked yet, so confirm it in your service manual. Where sources disagree, we leave the value out.
