See the schematic diagrams on page 3 as you plan the
locations to install the replacement components. Take into
consideration the routing of the electrical harnesses, hoses
and orientation of the replacement valves and the remote
mounting of the ECU controller. Note that the schematics
show the new air lines (some indicated as 3/8 inch) that will
be required for this repair.
Note: All torques specified in this document are assembly
torques and can be expected to fall off slightly after assembly.
traction
Do not re‑torque after initial assembly torques fall. For
assembly, use hand tools or torque limited drivers.
Do not use impact driver to install any fittings. Use a
professional grade thread sealant on all air lines connections
to the valves.
