REAR WHEEL – REMOVAL AND REFITTING
When removing the rear wheel it is easiest to do with the bike in a workstand to lift it from the floor, or with the
bike in the parked position (see folding instructions) so that the bike can support itself. If the tyre is deflated
it can pass through the brake pads more easily.
REMOVING THE CHAIN TENSIONER
Move the gear lever/s to top gear and back/forward pedal a little to engage, then fold the rear frame under
and park the bike. On a bike with a Sturmey Archer hub (3 or 6 speed gearing), slacken off the knurled lock-
nut N and unscrew the barrel B (fig. 45).
The indicator chain GICH will be left hanging loose from the end of the axle, this should be unscrewed and
removed. Move the sprung arm, CTARM, anti-clockwise and lift the chain off; allow the CTARM to move back
clockwise until it comes to a stop; undo the securing nut CTN (on a 3/6-speed this is a special nut, and on
a 1/2 speed it is a standard wheel nut) and remove it together with its washer. The chain tensioner assembly
may now be removed by drawing it sideways off the end of the axle.
REMOVING THE WHEEL
Slacken the wheel nuts by few turns, enough to allow any tab-washer to disengage from the axle plate. If the
axle or tab-washer tends to stick in the slots, push the rim from side to side to disengage the tab-washers
from the frame. The wheel can then be pulled away from the axle plates on the rear frame and the wheel
removed from the bike.
FITTING THE WHEEL
Make sure the chain passes round the rear sprocket. Drop the axle into the slots, with the tab washers the
correct way round (the tap marked TOP should fit into the cut-out on the axle plate above the axle slot). Make
sure that on each side the axle is seated against the end of the slot, and do up the wheel nuts, torque 18Nm.
FITTING THE CHAIN TENSIONER
Arrange the chain so that it is running over both chainring and rear sprocket (on a derailleur, providing high
gear is selected, this should be the smaller sprocket). The chain tensioner body has two flanges on its inner
face - these pass either side of the axle plate when fitting the chain tensioner; address the chain tensioner
to the axle plate and press home. Make sure that the fixed idler sprocket CTIDL (fig. 46) lies above (with the
rear frame inverted) the chain. On a 2 or 6 speed bike the CTIDL should lie between the “uprights” of the
chain-pusher-plate. Feed the chain-tensioner base onto the rear axle plate till it fits squarely.
