SWITCH ASSEMBLY
Using a circuit tester (set to "ohm"), 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.
| Terminals | Standard |
|---|---|
| S - M | 1 ohms or less |
| S - Ground | 1 ohms or less |
| M - B | 1 Mohms or more |

- Using a lead wire, connect the switch assembly terminal S to the positive terminal of battery, and the starter body to the ground terminal of battery. The pinion should be forced endwise on shaft. NOTE: With the pinion forced endwise on shaft, starter motor can sometimes rotate because current flows, through pull-in coil, to motor. This is not a problem.
- Disconnect the connector from terminal M. Then using a lead wire, connect the positive terminal of battery and terminal M, and ground terminal to starter body. In this test set up, the pinion should return to its original position even when it is pulled out with a screwdriver.
ASSEMBLY
Assemble in the reverse order of disassembly.
Note. Refer to component for tightening torque of each part. < Refer to GENERATOR , COMPONENT, General Description. > After assembling, manually turn the pulley to check that the rotor rotates smoothly.

- Assembling the rear cover and rectifier Remove old silicone grease on the mating surface of rear cover and rectifier and apply new silicone grease. CAUTION: Do not apply silicone grease to the attachment threads of rectifier.
- Push of the brush Before assembling the front and rear parts, press the brush down into the brush holder, then fix the brush in that position by inserting a [1 mm (0.0394 in) dia. 40 - 50 mm (1.5748 - 1.9685 in) long] wire through the hole as shown in the figure. CAUTION: After assembling, remove the wire.
- Install the ball bearings. Set the ball bearings in the front cover, then securely install an appropriate tool (such as a socket wrench of proper size) to the bearing outer race. Using a press to press the ball bearings into the specified location. Install the bearing retainer.
- Install the bearings. CAUTION: Do not apply grease to the bearings. If there is any oil on the bearing box, remove it completely. Use a press to install the bearings to the rotor shaft. Heat the bearing box in rear cover at 50 to 60°C (122 to 140°F), and then press the bearing into rear cover.
