Wiring Diagrams
Numeral on each wire is a "nominal size" according to JIS. C-3406 Low-voltage Electrical Wiring for Automobiles.(1) For standard type engines with alternator (with built-in IC regulator) or AC dynamo (2) For L2 engines of "Key-OFF stop" specification (With AC dynamo) (3) For standard engines of "Key-OFF stop" specification (4) For L2, L3 engines with glow timer, key-OFF stop specification (5) Three kinds of wiring diagrams for the engines with the "Key-OFF stop" system are shown above. Machines equipped with those engines may be in need of wiring modification to match with those key-OFF stop system circuits. In such a case, careful attention should be paid to the matters mentioned in the below. CAUTION (6) Combination of operations of components in "Key-OFF stop" (fuel cutoff solenoid) system circuit (7) Key switch connection for automatic glow system operations STARTER
Construction
Starter Component Parts(1) Front bracket assembly(2) Lever assembly(3) Spring set(4) Center bracket assembly(5) Switch assembly(6) Through bolt(7) Armature(8) Rear bearing(9) Pinion(10) Pinionshaft assembly(11) Gear(12) Yoke assembly(13) Brush holder assembly(14) Rear bracketInspection (Assembly)
If any abnormality is assumed by the following tests, adjust the starter or disassemble and repair it.(1) Pinion gap inspection(a) Interpose a battery (12V) between starter terminal "S" and starter body, and the pinion will protrude and stop. CAUTION Never apply battery voltage for over 10 seconds continuously.(b) Lightly push the pinion back and measure the return stroke (called pinion gap).(c) If the pinion gap is not within the standard range (0.5 to 2.0 mm), adjust it by increasing or decreasing the number of packings on the magnetic switch. The gap is decreased as the number of packings increases.
Inspecting Pinion Gap(2) No-load test(a) Connect the ammeter, voltmeter and battery to the starter as illustrated.(b) When the switch is closed, the pinion must protrude and the starter must run smoothly (at 3000 rpm or more). If the current or starter speed is out of specification, disassemble the starter and repair it.
No-load Test CAUTION* Use the thick wires as far as possible for wiring and tighten every terminal securely.* This is a solenoid shift type starter which makes a rotating sound larger than that of a direct-drive type starter.* When detecting starter rotation at the pinion tip, take care of protrusion of the pinion.(3) Magnetic switchPerform the following tests. If any test is not satisfied, replace the magnetic switch assembly.(a) Disconnect wire from terminal "M."(b) Attraction testConnect a battery to the magnetic switch terminals S and M. The pinion must protrude.
Attraction Test CAUTION Do not apply battery current for more than 10 seconds.(c) Holding testWith a battery connected to the magnetic switch terminal "S" and to the starter body, manually pull out the pinion fully. The pinion must remain at that position even when released from holding by hand.
Holding Test CAUTION Do not apply battery current for more than 10 seconds.(d) Return testWith a battery connected to the magnetic switch terminal "M" and to the starter body, manually pull out the pinion fully. The pinion must return to its original position when released from holding by hand.
Return Test CAUTION Do not apply battery current for more than 10 seconds.Disassembly
(1) Disconnect wire from the magnetic switch terminal "M."(2) Loosen two screws fastening the magnetic switch. Remove the magnetic switch assembly.(3) Remove two through bolts and two screws fastening the brush holder. Remove the rear bracket.
Removing Brush Holder Assembly(4) With two brushes brought in floating state, remove the yoke-and-brush-holder assembly. Then, pull the armature out.(5) Remove the cover, pry the snap ring out, and remove the washer.(6) Unscrew the bolts and remove the center bracket. At the same time, washers for pinion shaft end play adjustment will come off.(7) Pull out the reduction gear lever and lever spring from the front bracket.(8) On the pinion side, pry the snap ring out, and pull out the pinion and pinion shaft.(9) At each end of the armature, remove the ball bearing with a bearing puller.It is impossible to replace the ball bearing press-fitted in the front bracket. If that bearing has worn off, replace the front bracket assembly.
Removing Reduction GearInspection
Inspect the following: (1) Inspecting the magnetic switchCheck the magnetic switch for conduction between terminals S and M and between terminals S and body. If zero-ohm is indicated (as an evidence of short circuit), replace the magnetic switch.
Checking Magnetic Switch(2) Inspection the armature(a) Check the armature with a growler tester. If short-circuited, replace the armature. Also, check for insulation between the commutator and its shaft. If poorly insulated, replace the armature.(b) Measure the commutator O.D. and the depth of undercut. Repair or replace if the service limit is exceeded. Also, check the commutator outside surface for dirtiness and roughness. If rough, polish the commutator with fine-grain sandpaper.
Checking Armature Coil(3) Brush holder inspection(a) Check the brushes. If worn out beyond the service limit, replace the brushes.(b) Check the brush spring tension. If decreased beyond the service limit, replace springs.(c) Check for insulation between the positive brush holder and holder base. If poorly insulated, replace the holder assembly. Also, check the brush holders for proper staking.
Checking Brush Holders(4) Field coil inspection(a) Check for insulation between one end (brush) of coil and yoke.(b) Check for conduction between both ends (brushes) of coil.(c) Check the poles and coil for tightness.
Checking Field CoilAssembly and Adjustment
Reassemble the starter assembly in the reverse order of disassembly, giving care to the following:(1) Pinion shaft end play adjustmentSet the end play (thrust gap) to 0.5 mm or less by inserting an adjusting washer between the center bracket and reduction gear.(a) Fit the pinion shaft, reduction gear washer and snap ring to the center bracket.
Adjusting Pinion Shaft End Play(b) Measure end play by moving the pinion shaft in the axial direction. If end play exceeds 0.5 mm, increase the number of adjusting washers inserted.(2) GreasingWhenever the starter has been overhauled, apply grease to the following parts:
