2.6d Fit front drum brake wheels
Identify the left-hand and right-hand wheels (the
labels are on tape labels fastened to the spokes).
Locate the front wheel 12mm axle bolts with their
washers and 6mm nylock nuts. Remove the zip tie.
Slide an axle bolt through the hub from the outside of
the wheel (the side with the five webs on the hub
flange),
There is a small spacer inside the hub and it should
be fitted like the one in the picture. (Note the brake
plates are handed, and should be fitted so the brake
lever arm points forward and down towards the
ground. Now slide the bolt with the complete wheel
assembly through the kingpost, locating the single
hole in the black brake plate onto the drum brake pin
as per the picture below.
Put the washer and the M6 nylock nut onto the axle
bolt which is protruding on the inside of the kingpost.
Tighten using a 13mm (1/2”) wrench and a 10mm
wrench are needed to tighten the front wheels. After
the first time the nut has been installed and removed,
the 13mm wrench will not be necessary; you can lock
the axle in place by leaning gently on the wheel.
Before tightening the axle bolt (see table in Appendix
A for torque setting), check that the drum pin is
properly located. It is important that these bolts are
tight; you will not damage the bearing by tightening to
the required torque.
Repeat the fitting procedure for the other wheel.
Make sure the brake plate is located on the pin as this stops the
plate rotating.
This is
essential for proper operation of the brake.
Slide the brake cable adjuster
into the lower slot in the brake
plate. The brake cable clamping
barrel has been installed onto
the brake cable, but not
adjusted or tightened. Hook the
barrel over the actuating arm
and pull the slack out of the
cable; clamp the barrel into
place.
Adjust the brake by screwing out
the adjuster until the wheel
starts to drag slightly when
spun. Screw in again slightly
until the wheel runs freely.
Screw down the locking ring
tightly.
