(7) If clutch still does not hold, after correct control and spring tension adjustments have been made, clutch “pack” assembly must be replaced (par. [49]).
(8) After making clutch spring tension adjustment, replace outer front chain guard (par. [102]).
49. REMOVAL OF DISKS (figs. [28], [29], and [30]).
a. Clutch disks can be removed for inspection, cleaning, and/or replacing. Springs can be removed for checking and/or replacing without disturbing sprocket, which is integral with clutch shell. It is advisable to remove releasing (outer) disk, springs, and collar as an assembly because it is difficult to correctly aline, hold in place, and reassemble springs in this unit. If springs show signs of overheating, and appear to be “set,” they should be removed, measured, and replaced if necessary (par. [50]).

Figure 28—Removing Spring and Outer Disk Assembly
(1) Remove outer front chain guard (par. [102]).
(2) Remove push rod adjusting screw lock nut. Place a large flat washer, approximately 1⁄8–inch thick, 1¾–inch in diameter with a ⅜–inch center hole, over push rod adjusting screw, and replace adjusting screw lock nut just removed ([fig. 28]). Tighten adjusting screw lock nut against large washer until the three clutch spring adjusting nuts are free. Bend nut lock down, remove the three adjusting nuts, and withdraw releasing (outer) disk and spring assembly as one unit. Remaining lined and plain steel disks can now be removed from sprocket and clutch shell unit without further disassembly ([fig. 30]). NOTE: At time lined and plain disks are removed from shell, observe relative position of each disk in order of correct assembly.
