HYDROSTARTER - MAINTENANCE INSTRUCTIONS.
a.
The hydrostarter (starting) motor is mounted on the flywheel housing. The hydrostarter has a high rate of
acceleration; therefore, the engine is cranked faster than other starting systems.
b.
The control lever can be attached in any one of four positions where it is most accessible.
C
A positive starting motor engages the control lever by pushing the starter pinion into engagement with the
flywheel ring gear before the control valve is opened. When a tooth abutment is encountered, the valve permits a small
flow of oil to turn the pinion slowly until it snaps into full engagement. Spring action disengages the pinion and closes the
control valve when the lever is released. An overrunning clutch protects the starting rotor at all times from being driven
at high speeds by the engine before disengagement of the pinion.
