Engine Crankshaft Turns Too Slowly
Possible Causes/Corrections Low Battery VoltageCheck battery voltage. If battery voltage is less than 8 volts for a 12 volt system, or 16 volts for a 24 volt system, put a charge to the battery. If the battery will not hold a charge, load test the battery as shown in the Electrical System of the Testing and Adjusting Section of this Service Manual. Defective Cable Or Connection; Battery To StarterWith switch in START position, check voltage at battery cable connection to starter. If voltage is low at this connection and there is good voltage at the battery, check for defective cable or connection between the battery and the starter. Oil Too Thick For Free Crankshaft RotationUse the correct SAE grade oils for the temperatures that the engine is operated in. Make reference to the Operation & Maintenance Manual. At temperatures below -23°C (-10°F) it may be necessary to warm the oil for free crankshaft rotation. Defective Starter MotorRemove and test. Make repairs as necessary or install a new starter motor. Extra Outside LoadsDamage to the power take-off equipment (if so equipped) and, or transmission can put extra load on the engine. This prevents free rotation of the crankshaft. To check, disconnect the transmission and power take-off, and start the engine. Mechanical Problem Inside EngineTake the engine apart and check all components for damage.
