Kick Starter - Yamaha LB50IIAC Service Manual

Kick starter
1. Check the ratchet teeth on the kick gear
and ratchet wheel. The mating edges
should fit flush against each other. If
there is severe rounding off, replace as
set.
2. Check to see that the kick gear spins
freely on the kick axle. If not, replace
either or both as required. Replace if
any signs of galling are found.
3. Check to see that the ratchet wheel
(splined) slides freely on the kick axle.
Check for burrs or other damage.
Replace as required.
4. Check axle and wheel splines for wear.
The ratchet wheel is a fairly loose fit on
splines. However,
if wheel is so loose it
catches on shaft keeping ratchet wheel
spring from forcing it out, replace.
5. Check the ratchet wheel and kick gear
for damage, replace as required.
6. Check the kick pinion gear, second pi-
nion gear and spring for damage,
scratches, wear and fatigue.
