None.
Torque values are with Loctite applied unless otherwise specified.
All fasteners must be torqued to specifications. Use manufacturers’ torque values
for OEM fasteners.
The torque values supplied in Table 1 are intended for VMAC supplied components,
or for use as a guide in the absence of a torque value provided by an OEM.
Apply Loctite 242 (blue) to all fasteners (except nylon lock nuts)
unless otherwise stated.
