M66 Hydraulic Starter Motor

The M66 hydraulic starter motor is capable of producing a maximum torque of 216 Nm at 3000 psi (207 bar). The M66 is also fully cast iron (including the flange and pinion housing), making it suitable for all environments and resistant to damage.

M66 Hydraulic Starter Motor Power Curve

The M66 is fitted with a heavy duty inertia bendix and pinions which are machined from one cast block. This eliminates the process of pressing the pinion onto the bendix cup. A common method used by other starter motors and is a known fail point in many applications.

An easy reference guide for selecting the best starting system for your engine.

Non-spark pinions

Depending on your application, the M66 hydraulic starter motor can be fitted with either a steel or beryllium copper pinion. If the environment is potentially hazardous a beryllium copper pinion helps to reduce the risk of sparks.

 

Key advantages

  • Interchangeable design: Both the pinion and mounting flange are interchangeable. This enables the configuration of the starter motor to be altered to fit most types of engine.
  • Guaranteed start: Hydraulic energy can be stored indefinitely providing the system is installed and maintained to IPU specification. It can also be quickly and easily re-charged via a hand pump.
  • Performance in all conditions: Hydraulic starters are unaffected by either very hot or cold conditions provided the correct viscosity of oil is used. They similarly operate efficiently following extensive periods of shut down.
  • Low maintenance: Hydraulic starting systems are designed to last as long as your engine so why not enjoy low maintenance and replacement costs, as well as peace of mind? The system is enclosed with all internal components immersed in oil, protecting it from the adverse environmental conditions that damage electric or vane starters.
