- 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

- Differential cover bolts (RWD/4WD only) and transfer case fasteners
Repair guidance for this model year
For 2015 model-year work: This era introduced widespread torque-to-yield (TTY) bolts on head, main, and crank pulley fasteners. TTY bolts stretch permanently when torqued and must not be reused — the spec calls for a fresh bolt every time. Always verify TTY status against the FSM before 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 2015 Komatsu Pc300 8?
Specification not verified for this lug nut summary. Do not substitute another model year's value.
What socket size do I need for the 2015 Komatsu Pc300 8 lug nuts?
Confirm the socket against the actual lug nut; no size is assumed here.
Are the 2015 Komatsu Pc300 8 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.
