If you’re running a manual transmission car, you’ve to use a good clutch to maintain the smoothness of shifting gears. There’re various factors to be checked for having the best clutch for 7.3 powerstroke, such as the flywheel functions, pressure plate, frictions, pilot bearing, and release bearing.

A mediocre clutch will result in mediocre driving experience, and nobody wants that! You should use a high-quality clutch to get the most out of your vehicle. The use of clutch control at low speed can be used to obtain greater control of acceleration and engine braking, That being said, here is the review of the best clutch for 7.3 powerstroke available in the market.

In a summary-

What is a clutch in a car?

clutch is a mechanical device which engages and disengages power transmission and controls the connection between the shaft coming from the engine and the shafts which turn the wheels.

Clutch allows you to disengage the wheels from the engine (the engine generates power all the time) in order to change gear, allowing drivers to control over the speed of their car.

Benefits of Clutch

Torque Control: The primary job for a clutch is to transmit the torque from the engine to the drivetrain. It uses a friction surface to reduce the speed of the wheels.

Smooth Driving: The clutch helps to maintain the power flow between the engine and transmission. Consequently, you enjoy a smooth gear changing experience.

Engine: A good quality clutch will assist your vehicle’s engine in providing better performance and increasing the longevity of the engine. Thus, It saves you a lot of money in the long run and in a nutshell ensures

Brakes: By using correct techniques, you’re able to use the clutch as your brakes. The friction plate of the clutch helps to eliminate the acceleration.

Vibration: The flywheel and clutch plate works together to reduce any extra vibration while changing the gears. As a result, you feel at ease while increasing or decreasing the acceleration.

The Function of Clutch in Car

Connection establishment: The part clutch establishes an automatic connection among the drive-line and engine. This connection is activated manually for changing gear, as the motor is disengaged from transmission. Zero slippage occurs in-between the transmission and engine when the clutch is functional, meaning the transmission transmits all the torque and power of the engine to the driving wheel.

Transmission shift: There is a clutch plate in the primary automotive clutch with friction linings fitting in it that is attached between a spring-loaded pressure plate and the flywheel. The depressed clutch pedal enables the clutch cable to pull on the linkage so that the clutch can be disengaged. This disengagement allows the transmission to be shifted safely.

Transmission engagement: While the clutch pedal is released, the clutch plate is acted on by the pressure plate, which is spring-loaded. The pressure plate will pressure the clutch plate to reconnect the transmission and engine linkage.

TIP: There is a break-in period in all kinds of clutches. It would be best if you made sure that the clutch is not overheated by extreme slipping. Going by the instructions advised for break-ins or risk clutch failures is recommended.

How to choose the right clutch for your driving style and usage?

The intended use of the vehicle when choosing a clutch is the most important consideration. These are the prior issues to choose a clutch.

Step  #1 

Vehicle Weight : Many cars have a heavy engine that produces a huge amount of torque and causes slippage on the wheels.

Step  #2 

Horsepower and Torque : This is another subject to consider. The high torque and low RPM is suitable for the lower clamp pressure. Like this, low torque with high RPM is required for higher clamp pressure.

Step  #3 

Rear and gear : The higher the gear is, the more pressure is loaded on the clutch which may end up up bogging. Consider this before you choose your right clutch.

Step  #4 

Tire selection: Tires with more traction to hook up harder, releases the load on clutch.

Step  #5 

Intended use: There are a variety of driving lines for racing or in streetline, so the consideration of driving style is a must before choosing.

Note: It is possible to get up to 80,000 miles out of your clutch, shares AAMCO, but you’ll need to treat it well for this to happen. Source

6 Common Symptoms Of A Faulty Clutch

Sometimes replacement for 7.3 powerstroke clutch is required if the clutch is faulty. Here are the points to recognise it

Symptoms 1 : Clutch Slipping

This can be a result of various faults, for example, over adjustment of the clutch, friction lining’s excessive wear, pressure plate damage, driven plate’s oil contamination, and overheating the clutch. 

Symptoms 2 : Clutch Vibration

A common symptom is extreme jerking or shuddering output from the clutch engagement. The causes could be damage in the driven plate’s hub, flywheel or in the friction linings. These portions should be checked carefully before buying the clutch.

Symptoms 3 : Difficulty Shifting 

Uneven adjustment of the clutch release mechanism or pressure plate damage can create difficulty in shifting. Sometimes a grinding noise comes along with these symptoms.

Symptoms 4 : Clutch Pedal Hard To Depress- Hard clutch

This can be caused by the broken components that block the free movement of the diaphragm. It reduces the clamping force and makes the pedal harder. Hard clutch need a lot of force to get your clutch to work.

Symptoms 5 : Air in the line: for some reason sometimes air gets in the line where fluid needs to be, then, you will not get enough pressure in the system. And this results tends the whole system to operate incorrectly.

Symptoms 6 : Whining or Grinding When Clutch Pedal Depressed

A worn or damaged throwout bearing is always behind this faulty symptom. Low pitched grinding noise or a whining sound can be heard when the clutch pedal is pushed down. When the vehicle stops, the noise becomes quite obvious.

The Fundamentals of Clutch Operation

The clutch fundamental is that it disengages the power-flow to the transmission without turning off the engine. It disrupts any power or torque transmission as long as the two friction plates are not attached. As one friction plate is fixed and the other is not, the axial load put on the friction disk determines the torque delivery amount. More axial load amount ensures better power transmission, and less amount ensures reduced transmission of power. There are two main parts to your clutch: the clutch plate and the flywheel.

The diaphragm spring is attached for power disengagement. The power-flow is interrupted when the clutch pedal is pressed as the diaphragm spring will move the pressure disk away from the friction disk.

Clutch kit

  • The clutch bearing: The clutch bearing, AKA release bearing, connects the diaphragm to the pressure plates as the clutch fork occupies it, pressing it to the input shaft.
  • The pressure plate: The pressure plate is fixed to the flywheel, which allows it to rotate continuously along with the engine speed.
  • The clutch disk: The dual-sided disk rotates with transmission as it is fitted onto the friction surface. It catches onto both the friction surfaces.
  • The alignment tool: It is needed for installing the disk. It fits the disk in-between the flywheel and the pressure plate.
