With over 70 years of experience in specialist engineering, we are pioneers when it comes to on-site repairs and restoring industrial equipment to original manufacturer specifications.

Engine Crankshaft Repairs In Situ from Metalock Engineering

We have expertise in medium, large and very large in situ crankshaft repairs. We can address a wide range of common crankshaft issues and carry out the work on-site, helping you to avoid costly downtime and loss of revenue.

The crankshaft is a critical engine component but also one that is subjected to high levels of stress and wear because of continuous motion and heavy forces.

Engines are used in all industries throughout the world.

Marine/Offshore: ships, rigs and offshore installations all use large diesel engines as a means of either propulsion or power generation.

Industries such as mining, power generation, landfill gas, petrochemical, construction all use diesels engines to power plant and machinery. They are even used as a source of standby power generation for banks, hospitals and many are used to power our trains and large industrial vehicles.

Common Crankshaft Issues

There are several issues that can arise with crankshafts and crankshaft failure can happen at any time, even on well-maintained engines. Crankshaft issues are problematic because they can prevent the engine from working efficiently and if not corrected can cause total engine failure. This can lead to expensive repairs/replacements and downtime. This is why crankshaft repairs must be carried out as quickly as possible to prevent loss of revenue. A few of the most common issues that we deal with at Metalock Engineering include:

Bearing failure: Bearings can become worn over time, which can result is catastrophic engine failure.

Cracks and fractures: Cracks and fractures can occur from fatigue and continuous stress.

Corrosion and pitting: Corrosion and pitting can occur on the crankshaft journal diameter surface.

Bearing Journal Ovality: Crankshaft journals can become out-of-round from wear and tear, which can cause uneven distribution of forces and damage the engine.

Cam Effect or ridge wear: This condition develops over a period of time and can be identified as a protruding band that goes around the circumference of the crankpin journal diameter, The effect can cause extensive build up of heat which can harden the crankpin diameter causing problems in lubrication and eventual crankpin bearing failure sometimes causing disastrous results.
