3. Tighten the M10 mounting bolts.
A. Following the sequence shown in the previous figure, torque the eight
M10 bolts (A through H) to the value for the first increment shown in
the following table.
B. Repeat Step 3A for the second increment.
C. Repeat Step 3A for the final torque.
4. Tighten the M16 mounting bolts.
A. Following the sequence shown in the previous figure, torque the
sixteen M16 bolts (1 through 16) to the value for the first increment
shown in the following table.
B. Repeat Step 4A for the second increment.
C. Repeat Step 4A for the final torque.
Note To minimize negative clamping effects, you must torque the bolts in the
sequence shown.
5. Bolt the transducer/hub adapter to the road simulator fixture using the
modified lug nuts and shim washers provided.
Installing the lug bolts directly against the transducer face, without the anti-
galling compound and the shim washers, can cause galling of the
transducer face.
Galling of the transducer face can result in uneven torquing (and possible
over-torquing) of the lug bolts.
To prevent galling, always use the shim washers provided. Always lubricate the
bolts and shim washers as described below.
Lubricate the lug bolt threads, under the bolt head, and both faces of the
shim washers with the Nikal based anti-galling compound.
(Refer to the documentation provided with the road simulator.)
Tighten the lug nuts in 203 N•m (150 lbf•ft) increments, in the sequence
shown in the next figure to the torque rating recommended for the wheel.
Important Do not exceed a torque of 815 N•m (600 lbf•ft).
Bolt Size
Torque Increment M10 M16
1st Increment 24 N•m (18 lbf• ft) 108 N•m (80 lbf•ft)
2nd Increment 48 N•m (36 lbf• ft) 317 N•m (160
lbf•ft)
Final Torque 74 N•m (55 lbf• ft) 325 N•m (240
