7. Your rack has been shipped with the pressure and return line ports connected to it. You will need to
install the pressure and return line to the ports and install the rack with them connected. The lower
larger port on the rack is the pressure port and the higher smaller port is the return. As you are going
up into place with the bracket you will need to position the lines around the motor mounts and header.
This may take some time to find the angle you need but position the lines where you need so that
clearance is provided. Your rack and pinion is also centered before shipping and is marked make
sure not to move it off center or loosen the mounting blocks on the gear itself.
8. Once the rack is in place leave the bolts loose and install the shaft and joint from the rack and pinion
to the steering column. Slide the shaft onto the u-joint on the column and snug the pinch bolt. Run the
shaft down to the pinion, with the pinion joint on the shaft, raise the rack into place to spline the lower
joint to the pinion. NOTE: It is important that you phase the u-joint 90 degrees out or opposite of each
other before you install and tighten. Also make sure that you center your steering wheel before sliding
the u-joints together. Torque the u-joint bolts to 40ft. lbs.
Note: MAKE SURE YOUR RACK AND PINION IS CENTERED AND YOUR STEERING WHEEL IS
RESONABLY STRAIGHT.
