1. Install the overrunning clutch to the shaft assembly.
2. Use the following procedures to install stopper to the shaft assembly. Use the appropriate tool (such as the right size of socket wrench) to lightly tap on the ring to insert it into the shaft groove. (Scheme 36): Installing Stopper To Shaft Assembly Using the ST, press the stopper into the ring. (Scheme 37): Pressing Stopper Into Ring Using ST
3. Be careful of the following to install the shaft assembly to the front bracket. Lever direction (Scheme 38): Installing Shaft Assembly To Front Bracket Internal gear position (Scheme 39): Identifying Internal Gear Position
4. Install the plate. (Scheme 40): Identifying Plate
5. Install the planetary gear.
6. Be careful of the installation position to install the packing A and B. (Scheme 41): Identifying Installation Position Of Packing A And B
7. Install the armature to the yoke assembly.
8. Align the yoke assembly with the groove and install it to the front bracket. (Scheme 42): Aligning Yoke Assembly With Groove
9. Use the following procedures to install the brush holder to the yoke assembly. Push the brush into the brush holder, then use the appropriate tool (such as the right size of socket wrench) to fasten in position. (Scheme 43): Identifying Brush Into Brush Holder Align the brush holder with the groove in the yoke assembly, the slide to install. (Scheme 44): Identifying Brush Holder With Groove In Yoke Assembly
10. Align the rear cover groove with the brush holder assembly to install. (Scheme 45): Identifying Rear Cover Groove And Brush Holder Assembly
11. Install the rear cover set. (Scheme 46): Identifying Rear Cover Set
12. Use the following procedures to install the switch assembly to the front bracket. Insert the plunger and plunger spring into the switch assembly. Hook the protrusion on the plunger onto the lever end, then install to the front bracket. (Scheme 47): Identifying Switch Assembly
13. Install the connector to the switch assembly terminal M.

1. Check the commutator for signs of seizure or stepped wear caused by roughness of the surface. If there is light wear, use sandpaper to repair.
2. Run-out test Check for run-out on the commutator. If excessive, replace it. Commutator run-out: Standard: 0.05 mm (0.0020 in) Service limit: Less than 0.10 mm (0.0039 in) (Scheme 49): Checking Run-Out On Commutator
3. Depth of segment mold Check the depth of the segment mold. Depth of segment mold: 0.5 mm (0.020 in) (Scheme 50): Identifying Depth Of Segment Mold
4. Armature short-circuit test Place the armature on the growler tester to check for short circuits. While slowly turning the armature, support the steel seat for the armature core. If the circuits on the armature are shorted, the steel seat will vibrate, causing it to move to the core. When the steel seat has moved and vibrated, replace or repair the armature with the shorted circuit. (Scheme 51): Testing Armature Short-Circuit
5. Armature ground test Use a circuit tester to touch the probe of one side to the commutator segment, and the other probe to the shaft. If there is no continuity, it is normal. If there is continuity, the armature is grounded. If grounded, replace the armature. (Scheme 52): Checking Armature Ground

SWITCH ASSEMBLY

Using a circuit tester (set in ohms), check that there is continuity between terminals S and M, and between terminal S and ground.

Also check to be sure there is no continuity between terminal M and B.

Terminal / Resistance

S - M/1ohms or less

S - Ground/1ohms or less

M - B/1Mohms or more

Checking Continuity Between Terminals S And M, And Terminal S And Ground. Scheme 53

Assemble in the reverse order of disassembly.

1. Pull-out of the brush Before assembling, push the brush into the brush holder. Then pass a wire through the hole (dia. 1 mm (0.0394 in), Length: 4 to 5 cm (1.6 to 2.0 in) and fasten at that position. CAUTION: After re-assembling, remove the wire. (Scheme 54): Identifying Wire
2. Install the ball bearings. Set the ball bearings in the front cover, then firmly install the appropriate tool (such as the right size of socket wrench) to the bearing outer race. Using a press to press the ball bearings into the specified positions. Install the bearing retainer.
3. Using a press to install the bearings (rear side) to the rotor shaft.
4. Heat the bearing box inside the rear cover to [50 to 60° C (122 to 140° F] and push the rear bearings into the rear cover. CAUTION: Do not apply grease to the rear bearings. If oil adheres to the bearing box, completely wipe it away.
5. After re-assembling, manually turn the pulley to check that the rotor rotates smoothly.
