When changing the front synchronizing spring to secure the proper
clearance between this part and the spline shaft shoulder, it is
only necessary to remove the main drive gear and thread the spring
out through the synchronizing drum.
Assemble the shifter forks to the shafts. The notches on the second and high
speed gear shifter shaft go to the front, while the notches on the first and
reverse speed shaft go to the rear, as shown in Fig. 121.

When assembling the shafts to the forks, assemble the spring and
the ball in position. Insert shaft and turn to force ball and spring
down as shown in Fig. 122. Then push shaft to the center slot which
is the neutral position.
Fig. 122— Method of Assembling Shifter Fork
and Shaft
Assemble the reverse and first speed shifter fork and shaft and
second and high speed shifter forks and shafts to transmission.
Lock both shafts in position, using the large lock at the rear
and the small lock at the front, as shown in Fig. 123.
Assemble the interlock, checking for free movement. If the interlock
binds, loosen the lock screwsslightly, and tap the end of the shifter
shaft until the interlock moves freely. Assemble cover to transmission.
Place the gearshift lever in cover and check for ease of shifting
and proper gears meshing.

Replacement of Transmission in Chassis
After the transmission has been reassembled and is ready to be
replaced it in the chassis, it is in-stalled in the reverse order
of the removal operations.
TRANSMISSION (Standard Models) Construction
The transmission used in the Standard models closely resembles
the transmission used on the Master models.
It is very simple in construction. The silent second speed gear
is a constant mesh gear which is mounted to the rear of the spline
shaft next to the rear bearing to insure greater rigidity for this
gear. Between this second speed gear and the main drive gear is
a sliding clutch sleeve which is splined and fits over the spline
shaft. This sleeve permits engagement into either second or high
speed gears.
Operation
When the clutch sleeve is moved towards either second or high speed
gear by means of the gear shift lever, the teeth on the end of
the clutch sleeve engage or mesh with the teeth on the inside of
either the second or high speed gears.
By referring to Fig. 124 the various positions of the gears can
be readily seen.
Care
At least every 1000 miles the oil level of this transmission should
be checked and the proper grade of lubricant added to keep this
level even
