until fourth speed synchro ring seats in synchro hub

adapter h a s a shoulder on one side. The shoul­

(9) Slide countershaft (and adapter) into fixture
slot. Verify that countershaft and output shaft gears
are fully meshed before proceeding (Fig. 96).
(10) Check alignment of countershaft and output
shaft gear teeth. Note that gears may not align per­
fectly. A difference in height of 1.57 to 3.18 mm (1/16
to 1/8 in.) will probably exist. This difference will not
interfere with assembly. However, if the difference is
greater than this, the countershaft adapter tool is
probably upside down. Remove countershaft, reverse
adapter tool, reinstall countershaft and check align­
ment again.
