When serious machinery stops due to crankshaft issues, downtime and repair costs can skyrocket. Onsite inspection of crankshafts offers a smarter solution: bringing precision diagnostic tools right to the equipment, whether at sea, in a power plant, or on heavy-duty industrial engines. This method helps engineers identify wear, cracks, and misalignment without removing the crankshaft from its engine housing.
Core Steps in Onsite Crankshaft Inspection
Visual Examination: Check crankpin journals, oil holes, fillets, and counterweights for scoring, discoloration, or surface defects
Dimensional Measurements: Use micrometers and dial indicators to assess journal diameters, ovality, taper, and run‑out tolerances
Hardness Testing: Portable hardness testers confirm material strength and surface treatment integrity
Crack Detection: Utilize non-destructive methods, such as magnetic particle inspection, dye penetrant testing, or ultrasonics, to detect hidden cracks.
Surface Finish Check: Profilometers assess roughness to ensure the surface meets OEM standards.

Advantages of Onsite Over Workshop Inspection
- Zero Transportation Risk & Downtime
Avoid dismantling, shipping delays, and handling mistakes by inspecting in place. - Fast, Cost‑Effective Solutions
Field diagnostics and repair plans are generated immediately, minimizing production losses - Precision Checks with Portable Tools
Onsite techniques maintain OEM tolerances through calibrated gear and experienced technicians.


Common Issues Caught by Onsite Inspection
Crankshaft Cracks: Even faint stress lines become visible through NDT methods during routine checks.
Excessive Wear or Ovality: Regular measurement helps catch taper or roundness issues early and avoid journal failure.
Surface Damage: Polishing, grinding, or realignment can be scheduled ahead of major malfunctions.
The Role of Mobile In‑Situ Grinding & Repair
- In many cases, after inspection, it’s faster to grind or polish the onsite crankshaft using portable precision tools. This method:
- Restores OEM tolerances
- Straightens bent shafts
- Smooths surface imperfections
- Requires no crankshaft removal

FAQs:
Onsite crankshaft inspection involves checking the condition of the crankshaft at the equipment’s location, without removing it from the engine. It includes dimensional checks, crack detection, hardness testing, and alignment verification.
Insitu crankshaft repair minimizes downtime, avoids expensive transport or disassembly, and restores crankshaft geometry quickly. It’s a cost-effective solution for marine, industrial, and power plant engines.
Most inspections are completed within a few hours. If grinding or straightening is needed, the repair process may take 1–2 days, depending on the extent of damage and the number of journals involved.
