Types of Clutches

Push-type vs. Pull-type Clutches

  • Pull-type clutch:

    • Mechanism: Pulls the release bearing away when the pedal is engaged.

    • Pressure plate is connected to release bearing; both physically move apart upon engagement.

  • Push-type clutch:

    • Typically requires no physical adjustments.

Clutch Components

Pressure Plate and Release Bearing

  • Understanding the connection between the pressure plate and the release bearing.

    • Functionality: The pressure plate is actuated by levers linked to the release bearing.

  • As the clutch operates, the pressure plate's position is affected by the state of the release bearing.

Adjustment Mechanism

Clutch Adjustment Process

  • Initial Steps:

    • To maintain proper operation, physical adjustments are often required for pull-type clutches.

  • Adjustment Clearance:

    • Importance of maintaining a one-eighth inch clearance between release fork and release bearing as friction material wears down.

  • Effects of Wear:

    • Worn friction material advances the pressure plate forward, reducing clearance.

    • Observing free pedal loss affecting engine torque engagement, leading to clutch slip.

  • Adjustment Procedure:

    • Turn the threaded ring to return the pressure plate and release bearing to the original position.

    • Removal of lock tab needed for adjustment.

  • Physical Requirements:

    • Full engagement required: someone must hold the clutch pedal down.

    • Clockwise rotation is necessary to adjust pressure up.

Types of Adjusters

Manual Adjustment Tools and Techniques

  • Examples of adjusters:

    • Manual wrenches (size varies, typically 5/8”).

    • Understand adjustment notations (e.g., when to apply torque).

Automatic Adjusting Clutch

  • Example: Solo Clutch

    • No physical adjustments made by the mechanic.

    • Features automatic wedges that sense the wear and adjust clearance accordingly.

    • Indicator gauge reflects the condition of the clutch; fully over indicates new, while towards the end signals replacement.

Clutch Maintenance and Replacement

Required Components for Replacement

  • Three critical components replaced during a full clutch job:

    • Clutch Assembly:

    • Involves consult with clutch brand manual for specific assembly details.

    • Clutch Brake:

    • Pilot Bearing:

    • Typically located in the flywheel; critical for smooth engagement.

Clutch Mechanisms Overview

Drive Plates and torque transmission

  • Drive plates connect with flywheel to transmit engine torque, providing necessary clamping force.

Spring Types in Clutch Mechanisms

  • Coil springs: Disadvantages noted, as elongation leads to decreased clamping force with wear.

  • Diaphragm springs:

    • Formed from spring steel; provides effective pressure without losing efficiency even as friction materials wear down.

Clutch System Examples

Manual vs. Self-Adjusting Clutches

Self-Adjusting Clutch: Important Features

  • Identification of necessity for shipping bolts during installation to caging the pressure plate.

  • Explanation of care needed when handling both types, particularly noting the risks of improper handling.

Pitfalls in Clutch Replacements

  • Consequences of Incorrect Adjustments:

    • Failure to integrate shipping bolts risks unmanageable assembly issues and the need for re-pressing components.

  • Importance of proper identification of clutch type to take necessary actions during servicing.

Summary and Best Practices

  • Importance of consistent adjustment and understanding of clutch systems to ensure vehicle efficiency.

  • Awareness of signs of wear and the correct protocols for handling adjustments to prevent mechanical failures.
