Prestolite Hydraulic Starter System

The Prestolite hydraulic starter system provides starting for diesel engines predominantly used in safety critical applications.

It is usually used as part of a dual starting system to provide back up to the standard electric starter motor, but can also be used as the sole means of engine starting.

Two sizes of starter unit (B35G8 & B50G53) cover engines of 70 to 160mm bore diameter usually irrespective of the number of cylinders.

The system has a long history, but the basic efficient reliable design has remained largely unchanged throughout; originally developed in France by Demarreur Hydraulique Berger and subsequently manufactured by Bryce Berger and Lucas Bryce & Lucas Marine in the UK, the system is now built by Prestolite Electric, following their acquisition of the Lucas starter motor and alternator business at the end of the 1990's.

Further information on the system can be found in the downloads at the bottom of this page.
