1. INSPECT STARTER ASSEMBLY NOTE: These tests must be performed within 3 to 5 seconds to avoid burning out the coil. Perform the pull-in test. Disconnect the lead wire from terminal C. Connect the battery to the magnetic switch as shown in the illustration. Check that the clutch pinion gear extends. If the clutch pinion gear does not move, replace the magnetic switch. (Scheme 21): Inspecting Starter Assembly (Pull-In Test) Perform the hold-in test. Maintain the battery connections in step (a), but disconnect the negative (-) lead from terminal C. Check that the pinion gear remains extended. If the clutch pinion gear returns inward, replace the magnetic switch. (Scheme 22): Inspecting Starter Assembly (Hold-In Test) Check the clutch pinion gear return. Disconnect the negative (-) lead from the switch body. Check that the clutch pinion gear returns. If the clutch pinion gear does not return, replace the magnetic switch. (Scheme 23): Checking Clutch Pinion Gear Return Perform the no-load performance test. Connect the lead wire to terminal C. Make sure that the lead is not grounded. Clamp the starter in a vise. Connect the battery and an ammeter to the starter as shown in the illustration. Check that the starter rotates smoothly and steadily with the clutch pinion gear extended. Check that the ammeter reads the specified current. Specified current: 90 A or less at 11.5 V (Scheme 24): Inspecting Starter Assembly (No-Load Performance Test)
2. INSPECT REPAIR SERVICE STARTER KIT Check the plunger. Push in the plunger and check that it returns quickly to its original position. If necessary, replace the repair service starter kit. (Scheme 25): Checking Plunger Check if the pull-in coil has an open circuit. Measure the resistance between terminals 50 and C. Resistance: Below 1 ohms If the result is not as specified, replace the repair service starter kit. (Scheme 26): Measuring Resistance Between Terminals 50 And C Check if the hold-in coil has an open circuit. Measure the resistance between terminal 50 and the switch body. Resistance: Below 2 ohms If the result is not as specified, replace the repair service starter kit. (Scheme 27): Measuring Resistance Between Terminal 50 And Switch Body
3. INSPECT STARTER ARMATURE ASSEMBLY Measure if the commutator has an open circuit. Check the resistance between the segments of the commutator. Resistance: Below 1 ohms If the result is not as specified, replace the armature assembly. (Scheme 28): Checking Resistance Between Segments Of Commutator Check if the commutator is grounded. Measure the resistance between the commutator and armature coil core. Resistance: 10 kohms or higher If the result is not as specified, replace the armature assembly. Check the commutator for contamination and burns on its surface. If the surface is dirty or burnt, correct it with sandpaper (No. 400) or a lathe. (Scheme 29): Measuring Resistance Between Commutator And Armature Coil Core Using a vernier caliper, measure the commutator's length. Standard length: 3.3 to 4.0 mm (0.1299 to 0.1575 in.) If the length is greater than the maximum, replace the starter armature. (Scheme 30): Identifying Commutator's Length
4. INSPECT STARTER COMMUTATOR END FRAME ASSEMBLY Using a vernier caliper, measure the brush length. Specified length: 4.0 to 9.0 mm (0.158 to 0.354 in.) If the length is less than the minimum, replace the starter commutator end frame. (Scheme 31): Identifying Brush Length Check the brush insulation. Measure the resistance between the positive (+) and negative (-) brush. Resistance: 10 kohms or higher If the result is not as specified, repair or replace starter commutator end frame. (Scheme 32): Measuring Resistance Between Positive (+) And Negative (-) Brush
5. INSPECT REPAIR SERVICE STARTER KIT Check the starter clutch. Rotate the clutch pinion gear counterclockwise and check that it turns freely. Try to rotate the clutch pinion gear clockwise and check that it locks. If necessary, replace the service starter kit. (Scheme 33): Rotating Clutch Pinion Gear

2. INSTALL STARTER ARMATURE ASSEMBLY Apply grease to the plate washer and the armature shaft. Install the starter armature to the starter commutator end frame. Using snap ring pliers, install the plate washer and a new snap ring. (Scheme 35): Installing Plate Washer And Snap Ring Using a vernier caliper, measure length of the snap ring. Maximum length: 5.0 mm (0.197 in.) If the length is greater than the maximum, replace it with a new snap ring. (Scheme 36): Identifying Length Of Snap Ring
