Crankshaft Bearings & Sets

Crankshaft Bearings & Sets: Essential for Smooth Engine Performance

Crankshaft bearings play a crucial role in the operation of your engine, both for scooters, motorcycles, and cars. These bearings support the crankshaft, allowing it to rotate smoothly and efficiently transfer energy from the pistons to the rest of the drivetrain. But how do you know if your crankshaft bearings are worn out and what are the costs to replace them? In this article, we will give you all the answers to these frequently asked questions

Are bearings expensive to replace?

The replacement of crankshaft bearings can vary in cost, depending on various factors such as the type of vehicle, labor costs, and the price of the parts themselves. Generally, the bearings themselves are not extremely expensive, but labor costs can add up significantly because it is a complicated job that requires time and precision.

Here are some factors that influence the price:

• Type of vehicle: For smaller vehicles such as scooters or motorcycles, the costs are often lower compared to larger vehicles like cars. The price of the bearings themselves can vary from €50 to €150, depending on the brand and quality.
• Labor costs: However, labor costs can have a significant impact. Because the crankshaft and the bearings are located deep within the engine, the mechanic often has to dismantle the engine to reach them. This can take hours of work, making the labor costs substantial. In total, the costs for replacing crankshaft bearings can range from €300 to over €1000, depending on the complexity of the job and the rate of the mechanic.

Although the costs of replacing crankshaft bearings can be high, it is important not to ignore this repair. Worn bearings can cause serious engine damage if not replaced on time.

How do you know if your crankshaft bearings are broken?

It is essential to know when your crankshaft bearings need replacing, as worn bearings can seriously affect engine performance and ultimately lead to engine damage. Below are some common symptoms of worn or broken crankshaft bearings:

1. Rattling or knocking sound: One of the first signs of worn crankshaft bearings is a strange, knocking or rattling sound from the bottom part of the engine. This sound can occur because the bearings are worn and no longer run smoothly, resulting in play on the crankshaft.

2. Engine overheating: Worn bearings cause extra friction in the engine, which can lead to overheating. If you notice the engine overheating faster than usual, this could be a sign of wear on the crankshaft bearings.

3. Loss of power: Worn crankshaft bearings can cause the crankshaft to no longer rotate efficiently, which can result in a noticeable loss of power. The engine will run less smoothly, especially at higher revs.

4. Oil contamination: As the bearings wear, metal particles can end up in the engine oil. This can lead to oil contamination, which in turn can cause further damage to the engine. It's a good idea to regularly check your oil for signs of metal particles.

5. Engine vibrations: Another symptom of worn crankshaft bearings is excessive vibrations in the engine. This is because the crankshaft no longer rotates stably due to the worn bearings, resulting in imbalance.
