Rear Wheel-Brakes - Puch 1980-1981 Maintenance Manual

REAR WHEEL-BRAKES
When installing a rear wheel make sure that both wheels
are in alignment. Checking and adjusting is easily carried
out in any workshop, e.g. The rear wheel is aligned by sight-
ing from the rear (drive side) sprocket up to the engine
sprocket. These two sprockets must fall within the same
plane. Take two sightings down the chain to avoid error.
NOTE: Do not sight down the chain with the master link
on top. as it tends to distort the reading.
REAR WHEEL
When refitting the chains take care that the tension is correct
and the connecting links are properly placed with the closed
end pointing in the direction of chain travel.
The designed slackness of the driving chain midway between
the sprockets should be 3/4" (2 cm).
