Tightening torque pattern
Wheel bolts or wheel nuts
:—B
Using the pump lever, slowly turn the low-
X
ering screw on the jack through approx-
imately one revolution and carefully lower
the vehicle ( page 307).
Y
Put the jack aside.
X
Pull the rod with the smallest diameter off
X
the pump lever.
The shortened pump lever serves as a lug
wrench extension.
Starting with the middle rod, slide the lug
X
wrench extension as far as it will go onto
the lug wrench.
Using the extended lug wrench, tighten the
X
wheel bolts evenly in a crosswise pattern in
the sequence indicated (: to B).
Tighten the wheel bolts to the following
tightening torques:
Steel wheel 177 lb-ft (240 Nm)
R
Alloy wheel 133 lb-ft (180 Nm)
R
Tighten the wheel nuts to a tightening tor-
que of 133 lb-ft (180 Nm).
Push the piston on the hydraulic jack in
X
again and close the pressure release
screw.
Stow the jack and the rest of the vehicle
X
tools in the vehicle again.
You can now install the hub caps on steel
i
wheels with wheel bolts. The installing pro-
cedure depends on whether the hub cap
acts as a trim that covers the whole wheel,
or just covers the center.
Wheel and tire combination
Wheel with hub cap: position the opening
X
for the tire valve in the hub cap over the tire
valve.
Push the edge of the hub cap with both
X
hands against the wheel until it clicks into
place. Make sure the hub cap retaining
catches engage on the steel wheel.
Wheel with central hub cap: position the
X
retaining lugs of the central hub cap over
the wheel bolts.
Hit the middle of the hub cap to engage it on
X
the wheel.
Secure the faulty wheel in the spare wheel
X
bracket ( page 313).
Y
Vehicles with Super Single tires: transport
X
the defective rear wheel in the load area.
The rear wheel is too large for the spare
wheel bracket.
Check the tire pressure of the newly moun-
X
ted wheel and adjust it if necessary.
Observe the recommended tire pressure
( page 288).
Y
Retighten the wheel bolts or wheel nuts to
X
the specified tightening torque after the
vehicle has been driven for 30 miles
(50 km).
When using a wheel/spare wheel with a new
or newly painted wheel rim, have the wheel
bolts/nuts retightened again after approx-
imately 600 to 3,000 miles (1,000 to
5,000 km). Observe the specified tightening
torque.
Vehicles with the tire pressure monitor
i
system: all mounted wheels must be equip-
ped with functioning sensors.

General notes
! Retreaded tires are neither tested nor rec-
ommended for Sprinter vehicles, since pre-
vious damage cannot always be detected
on retreaded tires. We can therefore not
guarantee driving safety. Do not mount
