Figure 5-107. Figure 5-108 NOTE In step 25 (fig. 5-108), measurements for selection of proper diaphragm gaskets are being made. Figure 5-107 illustrates points at which measurements are made. The diaphragm, when install, must compress the entire clutch pack. The selection of proper gaskets depends upon the measurements taken in step 25 (fig. 5- 108). To determine gasket pack to be installed in step 28 (fig. 5-111), average the two measurements obtained in step 25 (fig. 5-108). Then choose gaskets as follows: (1) If average measurement is 0.010 to 0.015-use one 6774406 (73342) (0.012 thk) gasket (2) If average measurement is 0.016 to 0.021—use one 6774407 (73342) (0.016 thk) gasket (3) If average measurement is 0.022 to 0.027—use one 6774408 (73342) (0.021 thk) gasket (4) If average measurement is 0.028 to 0.033—use one each 6774406 (73342) (0.012 thk) and 6774407 (73342) (0.016 thk) gasket Install diaphragm (A) over guide bolts (B). Tap diaphragm until it seats against spacers. Install six 5/16-18 x 1-inch bolts and washers (C), evenly spaced. Tighten all six bolts to 10 pound-inches torque. Using a thickness gage, measure clearance between diaphragm (A) and housing (E) and (F) and opposite side as shown. See figure 5-107. Record both dimensions. Retighten two bolts 4910- 572-8701 (8356186) (D), and remove nine bolts and washers (C). The average of the two dimen- sions will be the required gasket thickness. (Guide bolts are part of set 4910-572-8710 (8356165).) 5-50
