GENERAL

The shift into fourth is made when mainshaft 2nd is disen-

parallel shafts supporting five gears each. The longer, or

mainshaft, also supports the clutch and serves as the input

shaft. The shorter shaft is called the countershaft.

5th Gear

Each gear on the mainshaft is in constant mesh with a corre-

The transmission gears are divided into two types, gears that

are splined and rotate with the shaft, and freewheeling gears

that ride on bearings and spin freely on the shaft. A splined

gear always meshes with a freewheeling gear. Also, three of

the splined gears are able to slide sideways on the shaft.

These sliding gears are used to change transmission

speeds. The projections (or dogs) on the sides of the sliding

gears, engage dogs on adjacent freewheeling gears, trans-

mitting power through the transmission.

Gear shifting is accomplished by three forks which fit into

grooves machined into the hubs of the three sliding gears.

The position of the shifter forks is controlled by a drum-

shaped shifter cam located on the top of the transmission.

Neutral

Power is introduced to the transmission through the clutch. In

neutral, with the clutch engaged, the mainshaft 1st and 2nd

gears are rotating, but no power is transferred to the counter-

shaft since countershaft 1st and 2nd are freewheeling gears.

1st Gear

When the transmission is shifted into first gear, countershaft

3rd, which rotates with the countershaft, engages counter-

shaft 1st, which has been spinning freely on the countershaft

driven by mainshaft 1st.

Now countershaft 3rd is no longer freewheeling, but locked to

the countershaft causing the countershaft and countershaft

5th to turn. Countershaft 5th transmits the power to the main

drive gear and the sprocket.

2nd Gear

Second gear is engaged when countershaft 3rd is shifted out

of countershaft 1st and engages countershaft 2nd. This locks

countershaft 2nd to the countershaft to complete the power

flow as shown.

3rd Gear

Two shifter forks are used to make the shift from second to

third. One fork moves countershaft 3rd out of countershaft

2nd to its neutral position, while another fork engages main-

shaft 2nd with mainshaft 3rd. This locks mainshaft 3rd to the

mainshaft to complete the power flow as shown.

ADJUSTMENT

If operating problems exist, check the shift linkage for wear,

interference or adjustment. If adjustment is necessary, see

SHIFT ROD below. If problems persist, see the checks under

Section 1.21 TROUBLESHOOTING, TRANSMISSION, along

with the repair procedures in this section.

SHIFT ROD

The shift rod is set at the factory and should not need adjust-

ment under normal circumstances. However, if full engage-

ment or full lever travel is not achieved, adjust the rod as

follows:
