ELECTRICAL SYSTEMTM 5-3805-263-14&P-2TESTING AND ADJUSTING1. To adjust the pinion distance, connect the solen-oid to a 12 volt battery as shown.Momentarily flash the jumper lead from the mo-tor terminal stud of the solenoid to the terminal studat (1) in the commutator end head to shift the solen-oid and drive into the cranking position.Remove the jumper lead.NOTE: The drive will remain in the cranking posi-tion until the battery is disconnected.Push the drive toward the commutator end of themotor to eliminate any slack movement in the link-age and measure the distance between the outsideedge of the drive sleeve and the thrust washer. Thedistance (3) must he .02 to .05 in. (0.51 to 1.27 mm).Adjust to this dimension by turning the adjustingnut (2) in or out as required.2. To test assembly of solenoid, it will be necessaryto have an interference block cut to the dimen-sions shown.Connect the solenoid to 24 volts as shown.Position the .9844 in. (25.003 mm) side of theinterference block against the pinion as shown andclose the switch in the battery circuit,With the switch closed and the .9844 in. (25.003mm) side of the interference block in place, the testlight must not light. Make sure the interferenceblock is against the drive gear and not against thedrive sleeve.CAUTIONDue to the amount of current being passedthrough the solenoid series winding, thesetests should be made as brief as possible.If the test light lights, the solenoid has been assem-bled wrong. Remove the cover from the solenoid andcheck the contact component assembly. If the testlight does not light. connect a carbon pile betweenthe switch and battery and voltmeter to the terminals(4) and (5).1-78
