The speedometer drive gear is located at the rear of
the mainshaft. The gear is secured on the shaft with
two snap rings.
SHIFT LE1ER AND LINKAGE
A floor mounted shift lever assembly (Fig. 2), is
used for selecting desired operating range. The lever
is attached to the adapter shift lever by a single shift
rod (Fig. 3). The floor linkage assembly is the same
as used on 4-wheel drive models with a transfer case.
The adapter shift lever is attached directly to the
shift sector shaft. Sector position is controlled by a
detent poppet, spring and screw (Fig. 4 ) . The poppet,
under pressure from the spring, maintains sector de­
tent position.
