(7) Install Adapter 6747-2A on front bearing hub of
countershaft, if not previously done. The shoulder
goes toward the countershaft.
(8) Slide countershaft (and adapter) into fixture
slot. Verify countershaft and output shaft gears are
fully meshed with the mainshaft gears before pro-
ceeding (Fig. 86).
(9) Check alignment of countershaft and output
shaft gear teeth. Gears may not align perfectly a dif-
ference in height of 1.57 to 3.18 mm (1/16 to 1/8 in.)
will probably exist. This will not interfere with
assembly. If difference is greater than this, the coun-
tershaft adapter tool is probably upside down.
(10) Position reverse idler in support cup of fixture
(Fig. 87). Verify idler gear is properly meshed and
aligned with shaft gear teeth and that bolt holes are
facing out from the geartrain. Adjust pedestal up or
down if necessary and verify short end of idler shaft
is facing up as shown.
