If your car’s engine is not running right, you might be able to fix it yourself with the help of a few common tools. However, if the main bearing is not working, you will need to take your car to a mechanic. This article covers how to change a main bearing in a car.
What is a Main Bearing?
What are main bearings? The main bearing is a type of bearing that sits inside the engine and helps to keep it running smoothly. When the engine is working properly, the main bearings help to reduce friction and ensure that the engine can turn quickly. However, if there are problems with the main bearings, the engine may not run correctly. In some cases, it may be necessary to replace the main bearings in order to fix the issue.
How do you Change Main Bearings in a Car?
If you’re having trouble starting your vehicle, there’s a good chance one of the main bearings is worn out. The problem can be fixed with a replacement, but it’s a good idea to check first to see if the bearing is the problem. Here’s how to check:
1. Remove the spark plugs and note which cylinder has a rough idle or no start. This is usually the engine that has the most wear on its main bearings.
2. With the car running, place a wrench on each side of each main bearing and spin it slightly while looking for any movement or looseness in the bearing. If one of the bearings is severely worn out, you’ll need to replace it.
What are the Risks Associated With Changing Main Bearings in a Car?
When you have a car that is older and has main bearings that may need to be replaced, there are always risks associated with the process. Here are four of the most common:
1. The bearings could fall out of the car while it’s being towed.
2. The bearings could become contaminated by oil or grease, potentially rendering them useless.
3. The new bearings could not fit properly and might need to be replaced again.
4. The car’s engine may not start if the main bearings are not replaced correctly.
How to Prevent Damage to Your Car If You Change Main Bearings Yourself
If you have a car with an engine inside, there’s a good chance you’ll need to change the main bearings at some point. But before you do, there are a few things you can do to protect your car and yourself from damage.
First, make sure you have the proper tools and supplies. You’ll need a socket wrench, ratchet and torque wrench, sealant (usually silicone or gasket maker), and a bucket or container for the waste oil.
Second, take your time. Changing main bearings can be a messy job, and if you rush it you may end up causing more damage than necessary.
Finally, be careful. Even if your car is parked on a stable surface, sudden movement can cause the engine to fall out of the car or worse yet, start rolling down the street.
Conclusion
No, you cannot change the main bearings on a car engine without special tools and experience. Changing main bearings can be an expensive and time-consuming repair, so it’s best to get it done by a professional.
