Lister Petters range of clutches, developed by Technodrive are specifically designed for attachment to diesel engines with SAE standard flywheel and housing connections The clutches are designed for switching the driven machinery on and off at rotational speed.

Design Features and Equipment

  • SAE Standard engine mounting arrangement
  • heavy duty asbestos-free friction plates
  • heavy duty output shaft bearings
  • sturdy manually operated selection lever
  • automatic wear plate adjustment

Operating Principle

Torque transmission is effected via a dry friction connection through resilient compression of the friction material discs when the clutch is engaged.

Dependant on the clutch size, the clutches are equipped with 1 to 3 friction material discs made from asbestos-free materials.


Over centre clutches operate as an on-off device allowing the engine to start on idle without load. This allows the clutch to be effectively used on drives demanding a high torque start, and where control of the driven equipment is required.

Examples of this are:

  • pump sets
  • plate compactors
  • wood chippers
  • refrigerated transport
  • standby drives


Your Lister Petter engine is precision engineered to give years of outstanding reliability and consistent performance in the most extreme temperatures and conditions.
