Installing a Coaster Brake Rear Wheel
text/3/20
Loosely fasten the wheel in
position. Put the small nut and
bolt back into the brake arm and
its holder strap. Do not tighten
it yet. Note: there should be one
or two washers on each side
between the axle nut and the bike
frame.
Check the chain tension while
turning the pedals. Sprockets are
not perfectly round and so the
chain tension will vary as they
turn. The correct tension is a
compromise. If there is periodic
resistance as the pedals are
turned, the chain is too tight and
can damage the bearings. If the
chain is too loose, (1/2" or more

deflection) it may fall off, which
is unsafe. By loosening the axle
nuts, one at a time, you can sort
of walk the wheel back and forth
to get the proper chain tension.
When you are satisfied, make sure
the nuts are tight and then
tighten the little nut and bolt at
the brake arm.
