● Place the kart on a trolley.
● Unscrew the 3 nylstop nuts from the rear wheels
with the proper size wrench, and then remove
wheels.
● Using a rule (1) or any depth gauge, measure
between the hub base (2) and the top of the axle
(3).
● Undo the CHC screws (4) of the rear hub with an
appropriate wrench until the hub can slide along the
axle shaft (6) and cotter pin (5).
● Move the hub (7) to the desired position with the
rule (1) in place against the hub base (2).
● Retighten and block the CHC (4) screws.
● Repeat the operation on the other hub.
● Replace both wheels following the rotation direction
indicated on tyre wall.
● Replace locknuts (nylstop) and tighten securely.

► Badly tightened wheels may lead to
severe, even fatal injuries.
► Check the hub key (5) is correctly
positioned.
► Never position the hubs beyond the
maximum allowed width: it may lead to
severe or even fatal injuries.
5.3.2 - Position of rear axle
On most tracks, the correct axle position is middle
position.
This corresponds to a low position of the chassis
relative to the ground.
● A large ground clearance means more grip.
● A low ground clearance means more
sliding.
5.3.3 - Type of axle
The stiffness of the axle plays an important part in the
behaviour of the kart.
● Visit ITAKA website for different axle types.
● A exible axle suits high grip conditions (Heat and
(or) gum on the track).
● A stiff axle suits low grip conditions (rain, humid
track, cold with little gum track).
In order to get the best out of your kart, do not hesitate
to test different stiffness of axle :
