The pinion must be removed before removal or replacement of the following parts:1 Front bracket2 Reduction gears3 Overrunning clutch
(1) Removing PinionThe pinion can be removed when it is held in the pushed-out position during energization of the solenoid switch. Disconnect the M-terminal connector and make a circuit that connects the starter motor and the battery as shown in the drawing. Close switches S1 and S2 to make the pinion come out and rotate. Then, open switch S2. The pinion will stop rotating but will stay in the pushed-out position. Apply a pipe-shaped implement to the pinion stopper and lightly tap it with a hammer to remove the pinion. If the pinion returns to the retracted position before disengagement of the stopper while the tool is being tapped, repeat the procedure from the beginning. (2) BallThe ball at the end of the armature acts as a bearing for movement of the armature in the thrust direction. When the armature is removed, the ball may stick to the grease on it. Be careful not to lose the ball.2.2 Inspection(1) Armature(a) Coil Short Circuit TestPlace the armature on a growler test. Hold an iron rod parallel with the armature and slowly rotate the armature by hand. If the iron rod vibrates or is pulled toward the armature, the armature has a short-circuited coil and must be replaced. (b) Coil Ground TestCheck whether continuity exists between the commutator and shaft (or core). If continuity exists, the coil is grounded and the armature must be replaced. (c) Commutator Inspection1) Measure the commutator's runout using a dial gauge. If the measurement exceeds the specified limit, rectify the problem, making sure that the outside diameter stays within specification. If the surface is rough or has stepped wear, rectify the problem with emery paper (#300-500).
Unit: mm (in.) 2) Measure the commutator's outside diameter. If the measurement is out of specification, replace the armature.
Unit: mm (in.) 3) Measure the molding undercut depth between segments. If the depth is smaller than the limit, cut the molding to a depth of 0.4-0.6 mm (0.016-0.024 in.).
Unit: mm (in.) (2) Field Coil(a) Coil Open Circuit TestCheck whether continuity exists between the terminal lead and each brush. If continuity does not exist, the field coil has an open circuit and the yoke assembly must be replaced. (b) Coil Ground TestCheck whether continuity exists between the yoke and each brush. If continuity exists, the coil is grounded and must be checked for defective insulation. If repair is impossible, replace the yoke assembly. (3) Brushes and Brush Holders(a) Brush WearMeasure the length of the brush. If the measurement is smaller than the limit, replace the brush. If the brush is worn unevenly or has a rough contact surface, rectify the problem
