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.

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:

1. What is an onsite inspection of a crankshaft?

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.

2. What are the benefits of insitu crankshaft repair?

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.

3. How long does onsite crankshaft inspection and repair take?

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.

In the world of marine, industrial, and power generation engines, crankshaft damage can bring operations to a standstill. Fortunately, onsite crankshaft repair and in situ crankshaft grinding services have revolutionized the way industries handle such emergencies, eliminating the need for disassembly or transportation.

What Is Onsite Crankshaft Repair?

Onsite crankshaft repair (also known as crankshaft repair onsite or on site crankshaft repair) refers to the process of repairing crankshaft damage directly at the site of operation. Whether on a vessel, power plant, or offshore platform, this service ensures minimal downtime and cost-effective solutions. The combination of onsite crankshaft grinding and repairing results in extended crankshaft life and improved engine performance.

In Situ Crankshaft Grinding: The Modern Solution

In situ crankshaft grinding, also known as insitu crankshaft grinding, is a specialized process where the crankshaft is ground in its original position using a customized onsite crankshaft grinding machine. This technique ensures perfect alignment and eliminates the need for dismantling. Our team provides advanced onsite crankshaft grinding services, ensuring the crankpins and main journals are restored to the original manufacturer’s specifications.

Why Choose In Situ Crankshaft Repair Services?

Fast turnaround
Eliminates transportation costs
Precision results with portable machines
Minimal downtime and disruption
Environmentally friendly approach
