5.3 Troubleshooting
Potential problems with the Hydraulic Linear Drive system and possible causes and solutions are described here.
Problem Possible causes Possible solutions

The motor is not receiving instructions
from the course computer. Check the connection between the autopilot control head and the course
computer, and between the course computer and the pump.

The motor brushes are worn. Check motor brushes. If necessary contact your dealer for replacement
brushes.
The clutch in the hydraulic ram unit is not
working correctly. Check for clutch operation.
Excessive air in the hydraulic ram unit. Check for air in the hydraulic ram unit. External oil loss may indicate this.
The system may need bleeding.
Motor runs, but erratic or no hydraulic rod
movement.
Drive coupling. Contact your dealer and ask them to check the motor drive coupling. The
dealer should ensure that the coupling is in place and aligned with the
motor drive tang.
Motor may be damaged or faulty. Check the motor for damage.
Excessive air in the hydraulic ram unit. Check for air in the hydraulic ram unit. External oil loss may indicate this.

certain that the fault is internal. Doing so will allow air into the
cylinder, requiring the unit to be bled.
