Here at Metalock Engineering, we are experts when it comes to everything related to crankshaft repairs. This includes the repair and restoration of crankshaft journals, which are a key component in engines. We are proud to be one of the largest on-site machining engineering groups in the world and have experience that dates back over 70 years, so you know you are in safe hands when you call us for your crankshaft journal repair needs.

What Is a Crankshaft Journal?

A crankshaft journal is the part of the shaft that rotates inside the bearing. There are two main types of crankshaft journals:

Main journals: Rest in the main bearings within the crankcase and provide rotational support

Connecting rod journals: Also known as crankpins, these are offset from the main journals and connect to the piston connecting rods.

Crankshaft journals are essential for supporting the crankshaft in the engine block and allow for motion conversion and lubrication of the engine. Crankshaft journals must be machined to high precision and are strong and durable in order to work properly, but there is a lot that can go wrong with crankshaft journals. Damage to the crankshaft journal can result in loss of oil pressure and engine failure, which is why it is so important to have a fast and reliable crankshaft journal repair service you can rely on.

Crankshaft Journal Damage

There are a number of ways that crankshaft journal damage can occur. Crankshaft damage can also happen at any moment, even on an engine that has been well-maintained. A few of the most common causes include:

Lack of lubrication: A lack of lubrication can cause damage by increasing friction from metal-to-metal contact.

Wear and tear: Gradual wear can occur over time, particularly when the engine is used on a daily basis.

Misalignment: Uneven wear and damage can occur due to misalignment of the crankshaft.

Thermal stress and corrosion: Crankshaft journals are often operating in harsh environments that can cause thermal damage as well as corrosive wear.

Crankshaft Journal Repair

Our crankshaft journal repair can extend the lifespan of the engine so that it does not have to be replaced prematurely. Repairing can be a more cost-effective option than replacement, and you can minimise costly downtime when you use our on-site repair services.

This means that we can reach you and get your issue resolved quickly to minimise disruption and downtime, even if you are at sea!

On-Site Work

With many repair services, you would need to take the entire engine apart and send parts away to be worked on. This can be disruptive as well as cost a lot of money. This is not the case when you use our crankshaft journal repair service, as we can usually carry out the work on-site, helping to get you up and running again and preventing the need for expensive transportation costs.

Industry Expertise

With over 70 years worth of experience, 400+ employees, 100+ countries served, and over 200 active projects, you know that you are getting experience when you choose Metalock Engineering for crankshaft journal repair. This experience means that we have worked in many different industries and work environments, so you can be reassured knowing that our technicians should be aware of the challenges and requirements of your sector and be able to conduct work while minimising disruption to your operations.

Our Repair Techniques

We have a range of repair techniques that can be employed to repair your crankshaft journal. Orbital machining is one of the most common methods used as it allows for accuracy while minimising downtime and allowing the work to be carried out in situ. Essentially, this is the process of rotating the machining tool around the journal to create a round surface. This is a tried and tested technique that can help to restore crankshaft journals. We can also provide cold Metalock repair technicians to repair potentially cracked components if the damage is caused by the failure of the structure of the engine block.
