Unmount the wiring assembly's alternator and set it down on a miite surface such as a workbench. Remove three nuts at the rear cover and nut and terminal insulator and take off the rear cover. Subsequently, six screws at the brush holder and voltage regulator must be unscrewed. Following the removal of the rear cover, the brush holder and the regulator should be pulled out from the rear end frame. If only the regulator is getting changed, then fit the new regulator, assemble the alternator and finally, fit the same on the engine. If replacing the brushes, then first note the size of the exposed portion of the brushes and then check whether it meets the minimum length; if not, then replace it. Also, make sure that each brush slide easily in the brush holder. To install the brush holder a small screwdriver is used to force down each brush against the shaft. Screw the nuts on the voltage regulator and brush holder at the rear frame after this, place the rear cover and tighten the three nuts until they are tight well. Last, add and then screw down the terminal insulator and at last, fit it with the alternator.

Remove the alternator.

Once the rear cover is removed, remove the five screws that retain the voltage regulator and the brush holder. Remove the brush holder and the regulator from the rear end frame.
