THREE SPEED TRANSMISSION
TROUBLESHOOTING TIPS - 3 SPEED       Look at the key and the notch in the gear that it engages.
Excessive wear to the tip of the key or the notch in the
gear may be the problem (Fig. 133).
TRANSMISSION
Hard Shifting
A
A raised boss molded into each gear causes the leading
edge of the key to depress before it can enter the next
gear (Fig. 132).

If the forces push straight on the key, it will drive the
axle. However, if due to wear the force tries to depress
the key, it can lower enough to disengage from the notch
in the gear (Fig. 134).

The ring on the shift collar end of the key holds the drive
end of the key up. If dried grease or dirt keeps the keys
from rocking up and down, the force required to shift
gears will increase. Check the cable for free movement
where it enters the transmission. These are quick checks
and should be made before opening the transmission.

Slipping Gears
B
The actual gears are in constant mesh. Unless gear
teeth are broken off, they cannot slip. If the wheels lurch
forward, then pause and lurch again, along with a loud
bang each time, the keys might be slipping.
