Problem 1: Contactor Switch For Water Temperature Does Not Activate Shutoff Solenoid Probable Cause:1. Wrong Connections: Connect battery to C and shutoff solenoid to NO connections. Check connections to other components or make installation of new wiring.2. Failure Of Shutoff Solenoid: Check the shutoff solenoid.3. Low Water Level In Cooling System: Fill the cooling system.4. Wrong Setting Of Switch: Make a test of temperature setting and if necessary install new contactor switch with correct setting. See specifications. Problem 2: Contactor Switch For Water Temperature Activates Shutoff Solenoid At Wrong Temperature Probable Cause:1. Wrong Setting Of Switch: Make a test of temperature setting and if necessary install new contactor switch with correct setting. See specifications. Problem 3: Contactor Switch For Oil Pressure Fails To Activate Shutoff Solenoid Probable Cause:1. Wrong Connections: Check connections, wiring and correct where necessary.2. Wrong Setting Of Switch: Test contactor switch. If necessary, install new contactor switch. Problem 4: Shutoff Solenoid Fails To Stop Engine Probable Cause:1. Wrong Connections: Check connections and wiring.2. Plunger Shaft Adjustment Wrong: Make adjustment to plunger shaft.3. Wrong Plunger In Shutoff Solenoid: Install the correct plunger shaft.4. Not Enough Plunger Travel: Make adjustment to plunger shaft or replace solenoid if necessary. Problem 5: Shutoff Solenoid Prevents Engine Start Probable Cause:1. Shutoff Solenoid Does Not Operate Correctly: Activate to shutoff or activate to run type: Operate the control for the shutoff solenoid. Listen for a noise. A shutoff solenoid makes noise when it works. If it makes noise but the engine still does not start, remove the shutoff solenoid. Try to start the engine. If the engine starts, the shutoff solenoid is either not installed correctly or it is bad. Make reference to Testing And Adjusting. Problem 6: Clutch Will Not Engage (Slips), Heats Or Lever Moves To Released Position Probable Cause:1. Wrong Adjustment: Make adjustment to clutch engagement lever pull.2. Alignment Of Flywheel And Flywheel Housing Mounting Face And Bores: Check and make adjustment to alignment.Overload On Clutch: Reduce load or reduce engine speed when engaging clutch. Problem 7: Clutch Shaft Has Too Much End Play Probable Cause:1. Bearing Worn Or Adjustment Wrong: Replace and/or make adjustment to shaft bearing. Problem 8: Clutch Bearings Have Short Service Life Probable Cause:1. Too Much Bearing Clearance: Replace and/or make adjustment to shaft bearing.2. Side Load Too High: Make a reduction of side load. Problem 9: Mechanical Shutoff Fails To Stop Engine Because Of Low Oil Pressure Probable Cause:1. Plunger Is Held In Normal Run Position Or A Spring Is Broken: Disassemble and clean parts. Install new parts if needed. Problem 10: Mechanical Shutoff Does Not Stop Engine When Coolant Temperature Is Too High Probable Cause:1. Oil Lines Have A Restriction: Clean oil lines, make replacements as necessary.2. Control Valve Does Not Work Correctly: Clean control valve, make replacement if necessary.3. Defect In Oil Pressure Shutoff: Clean oil pressure shutoff. Install new parts if necessary. Problem 11: Mechanical Shutoff Will Not Let Engine Start Probable Cause:1. Control Has Not Been Set For Start: Set the control for start.2. Spring Is Broken: Install new spring.3. High Water Temperature: Let engine cool. Problem 12. Electrical Gauges Give Wrong Readings Probable Cause:1. Wrong Connections: Check wiring connections to be sure they are correct.2. Sending Units Have A Failure: Check the sending units and install new ones if necessary.3. Resistor In 32 Volt Systems Has A Failure: Install a new resistor.4. Wrong Sending Unit In System: Install correct sending unit.5. Wrong Gauge: Install correct gauge. Problem 13: Contactor Switch For Overspeed Fails To Activate Shutoff Solenoid Probable Cause:1. Wrong Connection: Check connections and wiring. Correct where necessary.2. Wrong Setting Of Switch Make adjustment to setting or install new contactor switch if necessary. Make reference to Testing And Adjusting. Problem 14: Contactor Switch For Overspeed Activates Shutoff Solenoid At Wrong Speed Probable Cause:1. Wrong Setting: Make adjustment to setting or install new contactor switch if necessary. Problem 15a: Engine Speed Does Not Have Stability Probable Cause:1. Compensation Needle Valve Opened Too Far: Adjust the needle valve.2. Bad Lubrication Oil: Remove, drain and clean the governor. Make sure air is not held in the oil supply. Change the oil and make a replacement of the filter.3. Fuel Control Linkage Worn Or Not Correctly Adjusted: Inspect and adjust the fuel control linkage. Make repairs as necessary.4. Engine Fuel System Has A Failure: Use the Fuel System section in Testing And Adjusting as a reference. Make repairs as necessary.5. Negative Droop Set Into Governor: Adjust droop setting.6. Oil Does Not Drain Correctly From The Governor: Make sure governor drain passages have no restrictions.7. Buffer Springs Have A Failure: Make a replacement of the buffer springs.8. Governor Parts Worn: Disassemble and inspect pilot valve, power piston, flyweight pins, pin bearings, flyweight toes, flyweight head thrust bearing and centering
