Replacing your car clutch needn’t be a complicated or costly project; with just some sockets, a ratchet, and know-how, it can become an achievable weekend project.

If you plan to reuse an old clutch disc, be sure to inspect it for runout (an abnormal wear between its hub splines and those of the transmission input shaft) before installing it. Lubricate any new disc with graphite or molybdenum disulfide powder prior to installation.

Replacing a clutch is a meticulous task that requires precision and understanding of the vehicle’s transmission system. Whether you’re a DIY enthusiast or just curious about the process, here’s a step-by-step guide to help you understand clutch replacement:

  1. Safety First:
    • Always ensure the vehicle is on a stable surface.
    • Use jack stands to elevate the car safely.
    • Disconnect the battery to prevent any electrical mishaps.
  2. Access the Transmission:
    • Remove the gear shift or selector lever.
    • Disconnect the driveshaft by removing the rear U-joint.
    • Support the transmission with a jack and remove the transmission mounting bolts.
  3. Remove the Old Clutch:
    • Once the transmission is out of the way, you’ll have access to the clutch cover. Remove the bolts securing it.
    • Carefully take out the clutch disc and pressure plate.
    • Inspect the flywheel for any damages. If there are deep grooves or signs of overheating, consider resurfacing or replacing it.
  4. Install the New Clutch:
    • Position the new clutch disc and pressure plate on the flywheel.
    • Using a clutch alignment tool, ensure the clutch disc is perfectly centered.
    • Tighten the pressure plate bolts in a crisscross pattern to ensure even pressure.
  5. Reassemble the Transmission:
    • Carefully align and slide the transmission back into place.
    • Reconnect the driveshaft, gear shift or selector lever.
    • Ensure all bolts are tightened and components are reconnected properly.
  6. Final Checks:
    • Reconnect the battery.
    • Test the clutch pedal for any unusual play or resistance.
    • Start the vehicle and ensure smooth gear transitions.

Tips:

  • Always refer to the vehicle’s service manual for specific instructions and torque specifications.
  • Consider replacing the throw-out bearing and pilot bearing along with the clutch for optimal performance.
  • If you’re unsure about any step, it’s best to consult with a professional mechanic.

Remember, while replacing a clutch can be a rewarding experience for automotive enthusiasts, it’s essential to prioritize safety and accuracy throughout the process.

Flywheel

Flywheels are generally found between your engine and clutch assembly in most cars. Resembling a large disc connected to the end of your crankshaft, flywheels help increase engine power by storing rotational energy while providing a flat friction surface for Glasgow clutches to grab onto when they release their pedal.

The flywheel also works to absorb vibrations caused by combustion processes, helping the transmission run more smoothly and avoiding engine jarring when shifting gears or taking your foot off the accelerator pedal.

Faulty flywheels can quickly degrade your clutch, which is why they should be replaced as soon as any signs of wear or damage appear. Furthermore, worn-out flywheels may wreak havoc on other components in your clutch assembly, such as the pressure plate, pilot bearing, and clutch disc, making shifting gears harder or even causing the clutch to burn out completely.

Your vehicle’s flywheel plays an integral role in providing power to the vehicle, whether equipped with manual or automatic transmissions. A manual car will use a flywheel, while an auto may use something called a “flexplate.” Flexplates are lighter than flywheels while still helping transfer engine torque directly to transmission components.

When installing or replacing your clutch, it is wise to first remove the flywheel and pressure plate before beginning work on uninstalling and reinstalling the transmission. Make sure to wear a dust mask when working on a flywheel, as it may contain asbestos fibres.

Start by loosening the pressure plate-to-flywheel bolts criss-cross style until all spring pressure has been released, being careful not to overtighten them as this could warp the pressure plate and pose a danger to you and other drivers. After taking these steps, inspect the flywheel for signs of excessive wear, such as scoring or cracking of its splines; once removed, you can inspect its condition.

Pressure Plate

The pressure plate is an integral component of clutch assemblies, using springs and levers to maintain pressure on the clutch disc against its flywheel. In operation, however, it must be released in order for gears to engage. However, clutch systems produce heat, which wears down components, including potentially the pressure plate itself, leading to its possible degradation and resulting in hard shifting sensations if damage occurs to it.

Diaphragm types of clutch pressure plates are the most frequently seen on production cars, typically using Bellville-style springs for engaging and disengaging clutches. This design offers several benefits, including light pedal effort for the amount of pressure applied to the clutch disc. Older V-8 domestic cars, trucks, and pure drag racers may occasionally employ other pressure plate designs.

Most modern vehicles feature hydraulic pressure plates assisted by clutch slave cylinders. While this system is less likely to fail or have issues than older mechanical ones, it may still experience issues due to clutch master cylinder issues or fluid malfunctions.

Once a pressure plate has been replaced, it is vitally important that the new clutch disc be compatible with both the flywheel and transmission. This will help avoid any potential issues when engaging and disengaging transmission clutches in Glasgow.

To do this, carefully inspect the outside of your new clutch and compare it with its counterpart from before. Make sure the disc diameter matches and fits onto the flywheel without resistance; additionally, check that its height remains consistent with what was in its predecessor. If the new clutch is too high or too low, it will be difficult to engage and disengage the transmission, while too low could prevent pressure plate fingers from retracting into their release bearing. You should also ensure that the throw-out bearing is undamaged or worn; its purpose is to force pressure plate fingers back into their release bearing and disengage the clutch. A damaged bearing could make this more difficult or could eventually fail altogether.

Pilot Bearing

A pilot bearing (also called a pilot bushing) is installed into the end of a flywheel or crankshaft to support and centre the transmission input shaft when clutch disengagement occurs. Without its presence, however, the transmission input shaft could float freely, causing gear misalignment within the transmission and leading to hard shifting issues.

For optimal operation, pilot bearings must be completely frictionless in order to fulfil their duties effectively. To achieve this effect, light coatings of lubricant may be applied over the bearing to reduce friction; however, over time, this layer can wear away and new bearings must be installed as the existing ones become worn or require replacement.

An intermittent whirring noise during clutch engagement could be an indicator of wear on your pilot bearing. Furthermore, increased pedal pressure when depressing the clutch pedal may also indicate worn pilot bearings.

Changing a pilot bearing can be accomplished in an easy and straightforward manner. First, remove the old bearing using a tool with flexible fingers designed to grab and pull it from its hole. Or alternatively, use an attachment for your grease gun that pushes out hydraulic pressure through hydraulic push pins on the attachment to apply hydraulic pressure against it and force out any remaining bearing or bushing material from inside its holes.

Once the new bearing is in its proper position, it should be lubricated and secured using either a driver tool or socket. When properly aligned, two to four pins on its exterior should align with alignment dowels on the flywheel resurfacing project.

Misalignment of new bearings can result in misalignment between input shaft gear and counter-shaft gear that leads to transmission failure. To avoid this scenario, all clutch disc contact surfaces and the splined centre of the pilot bearing must be degreased and aligned carefully using an alignment tool prior to tightening the final bolts on this new bearing.

As soon as the tension has been established, it is vitally important that bolts be tightened evenly and in a star pattern to avoid bending the pressure plate and making shifting difficult. Once this tension has been adjusted, it’s advisable to use a clutch alignment tool so the disc and pilot bearing are perfectly in alignment.

Throw-Out Bearing

The throw-out bearing, clutch plate, flywheel, and pressure plate all comprise key parts of a car clutch system. When drivers press their clutch pedals, a mechanical fork or hydraulic system pushes forward on the transmission input shaft. A pushrod or hydraulic system pushes the outside shell of the throwout bearing forward onto the transmission input shaft until it slides against the pressure plate “fingers.” This allows pressure plate fingers to relax their force against the engine flywheel while disconnecting it from the transmission (allowing gear shifts). When released from clutch pedalling action, the throwout bearing returns back to its original position where power transfer occurs between transmission and engine—until next time!

Over time, the throw-out bearing can become worn or damaged and make depressing the clutch pedal more difficult, leading to grinding noises when pressing on it. If this is the case for you, a new strategy must be devised in order to reconnect it to its pressure plate when depressing the clutch pedal.

If you hear grinding or rattling sounds when pressing your clutch pedal, it may be time to inspect your throw-out bearing. As damage progresses, so will its noise. Additionally, vibration may also occur in your footwell when operating your clutch.

If you experience any of the symptoms below, it may be time for a clutch replacement. A defective throw-out bearing could lead to total clutch assembly failure, rendering your car undriveable. In most cases, replacing this component is relatively straightforward, although time-intensive as it requires dismantling of the transmission in order to access it; therefore, it may be beneficial to replace both the clutch and flywheel simultaneously with this repair job.

Your driving habits can help decrease the chance of clutch failure by relieving stress on its components. For example, taking care not to press down on the clutch when stopped or not actively shifting will avoid unnecessary wear on other related car components and reduce wear on bearings and bearings that make up your clutch pedal. Minimising foot time on the clutch pedal will also extend bearing lifespan and prolong bearing lifespan over time.
