Everything You Need To Know About Car Flywheel

What Is Flywheel?

A circular wheel which would be attached to the crankshaft of the engine is known as the flywheel. It would store the mechanical energy of the engine during power stroke and then the stored energy would be imparted to the preparatory strokes (i.e. suction, compression and exhaust stroke) during the process of car engine working. Just keep in mind that it is composed of steel or cast iron. It is generally utilized in the engine as well as the fabricating machines like rolling mills, punching machines, shear machines, presses etc.



Where Is Flywheel Located?

It is a disc which is generally bolted to the crankshaft at the rear of the engine. There are a lot of purposes which are served by it. When we talk about the manual transmission vehicle, then it would provide one of the friction surfaces for the clutch.

Types Of Flywheel

Are you searching for the different types of flywheel? Then don’t worry! All you have to do is to have a look below and then all your doubts regarding its types would be cleared.

 

  1. Single mass flywheel - There are a lot of factory standard flywheel which are generally made up of cast steel, heavy but hard wearing and durable. The most common type of light weight flywheel is generally composed of chrome moly or aluminum with bolt in friction plates. The best one would be the chrome moly, there can be some issues which can be caused by the aluminum ones if they won’t be fitted in the right manner.
  2. Dual mass flywheel - These types of flywheel are designed in such a way that they can reduce the noise, vibration as well as harshness. They would work in a similar way to the sprung centre clutch disc in which they would utilize the springs to dampen driveline shock and harmonics. They would not be very suitable for the performance applications as they would be a lot heavier than a conventional flywheel and then they would be prone to failure under heavy use or in extreme heat conditions.

How Do Flywheel Works?

Are you searching how do the flywheel actually work? Then all you have to do is to have a look below and then you will be able to understand everything.

 

A weighty wheel which would require a lot of force to rotate on its axis is known as a flywheel. Now when the wheel would be in motion at high speed, it would keep on spinning unless it would be stopped by applying lots of force. When it would start rotating, then a great amount of kinetic energy would be preserved by it which would be later used by it to power up a vehicle or machine at the time of beginning the engine or speeding up. More energy would be stored by the flywheel if it would spin at a higher speed or if it would have higher moment of inertia, which would mean bulkier. It would always work best when it would be spinned faster rather than increasing its mass.

Frequent Problems With Flywheel

Frequent Problems With Flywheel


Do you want to know some frequent problems which might start occurring in the flywheel? Take a look below to know some frequent problems with the flywheel:

 

  • There might be a lot of engine vibration
  • Clutch might start slipping
  • The automobile might not start at all

Symptoms Of Bad Flywheel

There are a few things which might cause your flywheel to malfunction. Watch for the following symptoms if you suspect a bad flywheel:

 

  1. Slipping - The most common issues with the clutch is not generally the flywheel, but it is actually the clutch assembly itself. All the clutches would start wearing out and then can also start to slip.
  2. Clutch Drag - The clutch drag is contrasting to slippage; it is a phenomenon which would occur when the clutch would start failing to release fully. It is the clutch drag which would make the clutch assembly to remain closer so that the engine could rpm during the shifting.
  3. Pulsation - The flywheel as well as clutch assemblies both function in a similar manner to the disc brake assemblies, that it the reason why they might exhibit similar symptoms after warpage. If there is a certain amount of warpage or "run out", then it would be normal and then it would result in the constant heating and cooling.
  4. Chattering - One of the most common issues is the clutch chatter which can start arising from a lot of malfunctions in the assembly. This issue might start arising when the clutch would “skip” on the flywheel, rapidly grabbing and releasing instead of engaging in a smooth way.
  5. Dual Mass Flywheel Problems - A dual-mass flywheel is generally two-part unit. A smaller-diameter flywheel would bolt to the car engine and it would then sit inside of a drum-brake-like outer flywheel. The smaller flywheel would engage the larger one via a set of springs.

Tools Needed For Flywheel

It is said that a workman is only as good as his tools, and it is definitely true when it comes to the car bodywork. It is vital to have the right tools to repair your Flywheel or else a straightforward job would turn into constant headaches. So that’s why we have listed out some invaluable tools below which you will need while repairing your Flywheel.

How To Change Flywheel?

How To Change Flywheel?


Do you want to change your flywheel on your own? Then have a look at the steps of changing the flywheel below:


It can be a daunting task to replace an engine flywheel, but if you are aware about the inner workings of the car, then there might be no need to take help from a mechanic. Its replacement process is not very complicated.


Step 1


Firstly, the drive shaft should be removed. Then the differential should be disconnected from the drive shaft. There would be a couple of bolts which would connect the drive shaft. A nut would be present on each end. These should then be removed with a wrench and then pull it away. A drop pan should be placed underneath the area where the drive shaft would meet the transmission. If there would be any fluid which would drain from the transmission, then it might start leaking into the drip pan.


Step 2


Then the other components should be disconnected. There would be a requirement to disconnect the transmission cooler lines from the transmission, the speedometer cable, and the shift linkage line. You can always use a wrench to disconnect these three components. The cooler lines should then be disconnected by utilizing a flare-nut wrench.


Step 3


After that the transmission should be disconnected. The transmission jack should be placed beneath the transmission. It should be then lifted until it would rest firmly on the oil pan. The transmission should then be disconnected by removing the retaining nuts which would attach it to the engine block. The flywheel can be revealed by pulling the transmission towards the back of the car once it would be disconnected.


Step 4


Then the old flywheel should be removed. The flywheel should then be held in place which would be found in its center. These can be removed with a wrench and then the flywheel should be removed carefully from the crankshaft by pulling it away. The replacement flywheel should then be put in its place and then the retaining bolts should be restored and then you should tighten them firmly.


Step 5


Then the transmission should be reattached. The transmission should then be slid back to the car engine and then carefully attach it in place. The torque converter should be aligned correctly with the holes of the flywheel. The retaining nuts should then be tightened to secure it in place. The retaining nuts to the transmission’s housing should then be returned and then they should be tightened. The two transmission cooler lines should then be reconnected by using the flare-nut wrench again. The speedometer cable and the shift linkage line should then be reconnected.


Step 6


Then the next step would be to carefully reinstall the drive shaft. If you want to replace the drive shaft, then it should be slid back into the rear of the transmission and its back should be positioned against the differential. The bolts which would remove in the Step 1 should then be returned and then you can always tighten them as per the need. The fluid should then be added back into the transmission.


Step 7


Then the vehicle should be tested. Now when everything would be put back together, then the vehicle should be tested so that the new flywheel is working properly.
