Solenoid Shift Electric Starters
Operation – Solenoid Shift Starter
When power is applied to the starter the electric
solenoid moves the drive pinion out onto the drive
shaft and into mesh with the fl ywheel ring gear. When
the pinion reaches the end of the drive shaft it rotates
the fl ywheel and cranks the engine.
When the engine starts and the start switch is released
the starter solenoid is deactivated, the drive lever
moves back, and the drive pinion moves out of mesh
with the ring gear into the retracted position.

1. Check for excessively dirty or worn brushes and commutator.
Clean using a coarse cloth (not emery cloth).
2. Replace brushes if excessively or unevenly worn.
1. Make sure the clutch or transmission is disengaged or placed
in neutral. This is especially important on equipment with
hydrostatic drive. The transmission must be exactly in neutral to
prevent resistance which could keep the engine from starting.
2. Check for seized engine components such as the bearings,
connecting rod, and piston.
