Testing field coil for open circuit(b) Test for no continuity between the slip ring and shaft (or core) as shown in the illustration. Any continuity shows there is a grounded circuit in the field coil. Replace the field coil.
Testing field coil for grounded circuit(3) Stator core(a) Test for continuity between the leads as shown in the illustration. No continuity shows there is an open circuit in the stator core. Replace the stator core.
Testing stator core for open circuit(b) Test for no continuity between each lead and stator core as shown in the illustration. Any continuity shows there is a grounded circuit in the stator core. Replace the stator core.
Testing stator core for grounded circuit(4) Brushes(a) Make replacement of brushes that have been worn down to, or beyond, the wear limit line.
Checking brush for wear(b) To remove the brushes from the brush holder for replacement, unsolder the leads from the brushes. This will permit removal of the brushes and springs.
Removing brushes for replacementTo install the new brushes, put them in position in the brush holder and solder the leads to the brushes.
Installing new brushes3. AssemblyFollow the reverse of disassembly and use the procedure that follows. (a) The rear bearing has a groove for the snap ring. Install the snap ring in this groove, make sure its tab is in the deep portion of the groove.(b) When installing the new rear bearing, put it in position with the side that has a groove toward the slip rings of the rotor.(c) To install the rear bearing in the rear bracket, heat the rear bracket.(d) Before installing the rotor in the rear bracket, insert a wire-shaped tooling into the hole in the rear bracket to lift the brushes off the slip rings. Remove the tooling after the rotor has been installed in position.
Assembling alternatorKEY SHUTOFF SYSTEM (ETS solenoid type)
1. GeneralThis system, consisting of a switch, a control timer and a solenoid, permits the operator to shut off the engine by turning the starter switch key to OFF position. Another function of this system is to shut off the engine automatically when the oil pressure is too low, or when coolant temperature is too high.
Key shutoff system2. Cord color (standard)
Control timer connection3. Shutoff solenoid installation (a) Remove the tie rod cover. (b) Coat the threads of the stop solenoid with thread sealant (Three Bond 1212). Coat the length of the threads to be turned in the governor case. (c) Temporarily install the shutoff solenoid and nut in the governor case.(d) Move the injection pump control rack all the way to the non-injection (shutoff) position.(c) Turn the shutoff solenoid in the governor case while pushing the plunger toward the control rack until the shaft is in touch with the tie rod. At this time, clearance C must be 0 mm. (Under this condition, the plunger will be rotated by the shutoff solenoid being turned in.)(f) Back off the shutoff solenoid 30° to 45° turn (the clearance between the control rack and plunger will be
