The M38 hydraulic starter motor is capable of producing a maximum torque of 124Nm at 3000 psi (207bar). The M38 is also fully cast iron (including the flange and pinion housing), making it suitable for all environments and resistant to damage.
The M38 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.
Depending on your application, the M38 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.
