Fig. 1D-42 Selection of Proper A-6 Shoe Disc
20B. A n alternate m ethod of selecting a proper race is
to use G age Set J 9661-01 selecting a suitable feeler gage leaf
until the result is a 4 to 8 ounce pull on the scale between
the rear th ru st bearing and upper (which also happens to
be the outer rear) thru st race (Fig. ID -44). If the pull is just
less than 4 ounces, add .01mm (.0005") to the thickness of
the feeler stock used to m easure the clearance. If the pull
on the scale reads ju st over 8 ounces, then subtract .01mm
(.0005") from the thickness of the feeler stock.
21. F o r either m ethod used, select a th ru st race with
a "num ber" corresponding to two (2) full sizes larger than
D ial Indicator or Feeler Gage m easurem ent of the am ount
of end play shown. (If m easurem ent is .17mm (.007"), select
a N o.9 or 090 race.)
Place thrust race in right-hand slot at bottom center of
parts tray J 9402.
