1.
Disconnect the negative (-) terminal.
Disconnect the negative (-) terminal.
Disconnect the generator connector and remove the "B+" terminal cable.
Loosen the belt tension adjusting bolt and remove the mounting bolt.
Remove the belt by pushing the generator inward.
Remove the generator assembly.
Installation is the reverse of removal.
Position the generator and insert the support bolt. (Do not attach the nut)
Push the generator forward and determine how many spacers (thickness : 0.198 mm) should be inserted between the front leg of the generator and the front case. (space "A" in the illustration)
(There should be enough spacers so that they do not fall out when you let go of them.)
Insert the spacers (space "A" in the illustration), attach the nut, and complete the installation.
Remove the generator cover using a screw driver.
Loosen the mounting bolts and disconnect the brush holder assembly.
Remove the slip ring guide.
Remove the nut, pully and spacer.
Loosen the 4 through bolts.
Disconnect the rotor and cover.
Reassembly is the reverse of disassembly.
Check the rotor coil for continuity. Check to make sure that there is continuity between the slip rings. If resistance is extremely low, it means that there is a short. If there is no continuity or if there is a short circuit, replace the rotor assembly.
: Approx. 3.1Ω
Check the rotor coil for ground. Check to make sure that there is no continuity between the slip ring and the core.
If there is continuity, replace the rotor assembly.
Make a continuity check on the stator coil. Check to make sure that there is continuity between the coil leads.
If there is no continuity, replace the stator assembly.
Check the coil for grounding. Check to make sure that there is no continuity between the coil and the core.
If there is continuity, replace the stator assembly.
Unsolder the pigtail and remove the old brush and spring.
Install the brush spring and a new brush in the brush holder.
Insert the brush so that there is a space of 2 to 3 mm (0.079 to 0.118 in.) between the limit line and the end of the brush holder.
Solder the pigtail to the brush holder.
