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).)
