The most common industrial applications are in rock crushers and wood chippers. This seal is available for all products that use the 237-1962 Electric Starting Motor Gp, except for wet sump flywheel housings. The seal will stop dust accumulation on the armature spline that could prevent the pinion drive assembly from translating during normal operation.

The new 419-7866 Starter Seal is adaptable back to the first production of the listed engines.

If the starting motor on an above listed engine exhibits symptoms like, click-no-crank, running engaged and a shorted or open circuit, make the following improvement.
