M66
The M66 hydraulic starter motor delivers exceptional torque and proven durability for the most demanding applications.
Producing a maximum torque of 216Nm at 3,000 psi (207 bar), the M66 is built entirely from cast iron—including the flange and pinion housing—making it suitable for all environments and resistant to damage.
SOLUTION DETAILS
Heavy-duty design
The M66 hydraulic starter motor is engineered for high-output performance, delivering up to 216Nm of torque at 3,000 psi (207 bar). Its robust, fully cast iron construction ensures maximum durability and resistance to wear in all operating conditions.
Precision-machined components
Equipped with a heavy-duty inertia bendix and pinions machined from a single cast block, the M66 eliminates the process of pressing the pinion onto the bendix cup—a known failure point in other starter motor designs.
Non-spark pinion option
Depending on your application, the M66 can be fitted with either a steel or beryllium-copper pinion. In potentially hazardous environments, the beryllium-copper pinion offers additional protection by reducing the risk of sparks.
Key Advantages
- Interchangeable design: Both the pinion and mounting flange are interchangeable, enabling the starter motor to be adapted to fit most types of engine.
- Guaranteed start: Hydraulic energy can be stored indefinitely when installed and maintained to Powerstart specifications, and can be quickly recharged via a hand pump.
- Performance in all conditions: Operates reliably in extreme hot or cold temperatures with the correct oil viscosity, and remains efficient even after long shutdown periods.
- Low maintenance: Designed to last as long as your engine, with enclosed components immersed in oil for protection against environmental damage—reducing maintenance and replacement costs.
