Machine Variants
Where information is different depending on machine
variant, the applicable information sets are included
within the same PIL reference. Headings are
included to identify which information is for which

is applicable. Use the applicable Servicemaster
vehicle set-up tool.
• Use the applicable Servicemaster diagnostics
tools.
Torque Tightening
When you replace components, always tighten the
applicable fixings to the correct torque value. Use the
torque tightening values contained in the individual
procedures (Remove and Install, Disassemble and
Assemble etc.). If no torque values are specified, use
the standard torque tightening values. For the torque
setting to be effective, do the following before you
install the fixings. Refer to PIL 72-00-00.
• Make sure that all the applicable component
assemblies are correct.
• Make sure that the applicable fixings are to the
correct specification. If necessary discard the
original fixings and replace them with new ones.
The relevant procedures indicate when this is
necessary.
• Make sure that the applicable fixings and
threaded holes are free from contamination.
This includes dirt, debris, old sealants and
compounds, fluids and lubricants.
