cover, on the side facing the engine). Then scribe another
line at a right angle across the first, from the pump body onto
the cover. These scribe lines are to enable you to reinstall the
cam plate cover in exactly the same position. You may make
any additional scribe lines if you feel it may be helpful.
Loosen and disconnect a rubber hose and a plastic
tube from a “tee” fitting located in the air flow valve
cover. This is a smaller cover attached to the rear of the cam
plate cover, with four screws facing the rear of the engine.
The upper forward screw attaching the cam plate
cover to the fuel pump body has a factory break-off
tamper proof head. This screw head must be modified to
provide some means of removal. A sharp chisel with an
approximately
3 ⁄
8
" wide blade may be used to chisel a
screwdriver “slot” across the screw head. Pass the chisel
between the injector tubes and strike straight down to
create a “V” notch, then use a
5 ⁄
16
– 3 ⁄
8
" blade screwdriver
with moderate downforce to turn the screw. See Figure 5.
An alternate method is to drive the chisel into the screw
head using blows upon a hand held impact driver tool set
in the “removal” position, such as a Snap-On No. PIT 160
or equivalent. Install a hex or 8-point socket on the driver
that will fit over the shank on the chisel. Another method is
to drive a No. T15 (or in some cases a No. T20) male
TORX bit into the screw head using either a hammer or
hand impact driver. A center punch may be required to
provide a depression in the top of the screw. When using a
hand impact driver, use light hammer taps to seat the TORX
bit, and progressively harder blows to loosen the screw.
Once this screw has been removed, save the washers and
discard the screw, then loosen and remove the remaining
three screws and retain these for reassembly. Remove two
fuel shutdown solenoid bolts and the hairpin style clip from
the solenoid acctuator rod. Remove the solenoid and set it
aside. Loosen slightly one bolt at the rear of the injection
pump that will allow the fuel shutdown solenoid and
bracket to be swung outboard just enough to clear the
edge of the cam plate cover so the cover can be removed
from the pump. Now remove the cam plate cover and set it
aside. (
See Fig. 6 )
Note the position of the cam plate attached to the
pump body by two screws. Mark a scribe line in
the pump body at the forward edge of the cam plate
where it contacts the pump body. See
Figure 7 . This mark
can be used as a reference should the original cam plate
need to be reinstalled.
Place the installation guide template provided over
the stock fuel cam plate. This template will provide
the position reference for the Banks OttoMind calibration
cam.
Note: The guide template will only fit one way. If it
appears to be misaligned or does not seem to fit, flip the
plate over and try again.
Using two of the cam cover screws previously
removed, loosely attach the guide template to the
fuel pump body. Slide the guide template toward the rear
of the engine so that there is zero clearance between the
front edge of the fuel cam plate and the guide template.
Hand tighten the two screws so that the guide template
DOES NOT move during the remainder of the Banks
OttoMind installation.
Loosen and remove the two screws holding the fuel
cam plate in place. Keep these for reuse. Remove
the stock fuel cam plate. Keep this piece in a safe location
in case it is needed for future work on your vehicle.
Install the Banks OttoMind fuel calibration cam in
the same position as the stock fuel cam plate, with
zero clearance between the front edge of the calibration
cam and the guide template. Replace the two screws to
retain the calibration cam and tighten. Remove the
installation guide template and keep it with your stock fuel
cam plate for future use.
Once the Banks OttoMind is installed, replace the
cam plate cover on the pump, swing the fuel
shutdown solenoid bracket into place and reinstall the fuel
shutdown solenoid. Thread the two lower cover screws
into the pump finger tight. Install one original screw in the
upper rear bolt hole. Install the supplied phillips head
screw in the upper forward bolt hole. This is a temporary
use screw to be replaced once final fuel calibration is
confirmed. It is recommended that vehicle performance
be verified before the final installation of the break off
screw. Tighten the bolts, while positioning the cover to its
exact original position, as indicated by your scribe lines
on the cover and pump body. Tighten the rear fuel
shutdown bracket bolt that was loosened for cover
removal. After engine performance is checked, replace
the phillips head screw with the break off screw provided.
Reconnect the rubber hose and plastic tube to the
“tee” fitting on the air flow valve cover, tighten the
hose clamp and tube nut.
This completes the injection pump adjustment procedure.
