HARD STARTING
-------------------------------- -------------------------------- SUGGESTED REMEDY -------------------------------- ------------------------------
1. Refer to Items 2, 3 and 5 and perform the operations listed.
2. Replace the starting motor switch.
3. Hand crank the engine at least one complete revolution. If the engine cannot be rotated a complete revolution,
internal damage is indicated and the engine must be disassembled to ascertain the extent of damage and the cause.
4. Refer to Lubricating Oil Specifications in Section 13.3 for the recommended grade of oil.
5. Recharge the battery if a light load test indicates low or no voltage. Replace the battery if it is damaged or will not
hold a charge.
Replace terminals that are damaged or corroded.
At low ambient temperatures, use of a starting aid will keep the battery fully charged by reducing the cranking time.
6. Tighten the starter connections. Inspect the starter commutator and brushes for wear. Replace the brushes if badly
worn and overhaul the starting motor if the commutator is damaged.
7. To check for air leaks, flow obstruction, faulty fuel pump or faulty installation, consult the No Fuel or Insufficient Fuel
chart.
8. Check for bind in the governor-to-injector linkage. Readjust the governor and injector controls if necessary.
9. Remove the cylinder head and recondition the exhaust valves.
10. Remove the air box covers and inspect the compression rings through the ports in the cylinder liners. Overhaul the
cylinder assemblies if the rings are badly worn or broken.
11. To check for compression gasket leakage, remove the coolant filler cap and operate the engine. A steady flow of
gases from the coolant filler indicates either a cylinder head gasket is damaged or the cylinder head is cracked. Remove
the cylinder head and replace the gaskets or cylinder head.
12. Adjust the exhaust valve clearance.
13. Inspect the blower drive shaft and drive coupling. Replace damaged parts.
14. Operate the starting aid according to the instructions under Cold Weather Starting Aids.
