Locate the alternator attaching bolts, take out those bolts and set down the alternator in an efficient workstation. Removal of three nuts attached to the rear end cover, a nut and terminal insulator, and the rear end cover. Next, teh screws that secure the voltage regulator and the brush holder can be withdrawn after the removal of the rear end cover. Take off the brush holder and the regulator of the rear end frame. If only the regulator is involved, then fitting a new one, reassembling the alternator then fitting it on the engine should be done. If the brushes are being replaced, then, ensure that each brush is measured from the point where it is exposed to the outside and if the brush is shorter than the minimum exposed length all the brushes should be replaced. Make certain that each brush, slides easily in the brush holder. In fixing the brush holder, one has to press the brush on a small end of the screw driver to ensure that the shaft is free. Following this, secure the screws of the voltage regulator or the brush holder in the rear end frame. Fix the rear end cover and use three nut screws to tightly fit over the respective locations. Last of all, screws the terminal insulator and unto and again bolts the alternator onto its rightful place.

Measure the exposed length of each brush and compare your measurements to the specified minimum length. If the length of either brush is less than the specified minimum, replace the brushes.

Holding the new regulator and the brush holder as shown, install them together. Installation is otherwise the reverse of removal. Refer to Steps 14 and 15 in Section 17.
