MANIFOLD INSTALLATION
Manifold installation will usually be done along with
installation of Edelbrock cylinder heads. Refer to cylinder
head instructions for step-by-step procedures, if necessary.
These instructions cover only the procedures that apply to
Edelbrock 3-piece intake manifolds.
1. Place manifold in position on cylinder heads, being
careful not to pinch or fold-over the grommets.
2. Start all four manifold bolts and washers by hand, then
tighten each bolt gradually, moving from bolt-to-bolt in
small steps. There is no room for a torque wrench, but
final torque should be very firm (18-23 ft./lbs.). If desired,
you may use a non-permanent locking compound, such
as green Locktite
® , on bolt threads. NOTE: You must use
the AN washers supplied on the manifold bolts to prevent
over-stressing and cracking the flanges.
3. Install the factory fuel injector retaining bracket over the
rear of the fuel rail to secure the fuel injectors.
4. Attach the factory fuel
line to the fuel rail using
the stock retaining clip
and Torx screw.
NOTE:
Use care not to damage
the stock fuel line o-
ring seal.
TROTTLE BODY INSTALLATION
1. Insert the factory MAP sensor into the Edelbrock intake
manifold.
2. Apply a light film of white grease, or brake cylinder
assembly lube to the throttle body o-ring seal to hold it in
place during installation.
3 Install the throttle body onto the intake manifold using the
supplied 4mm x .7, 20mm long socket head capscrews.
Make sure the tab on the throttle body lines up with the
MAP sensor to hold it in place.
NOTE: When installing the
throttle body, the use of a ball-end 4mm Allen wrench or
4mm ball-end Allen driver is necessary for tightening of
the capscrews.
Because the 3-piece manifold “floats” between the two
cylinder heads, it is very important that the throttle body is
properly supported to prevent manifold droop and resulting in
leakage at the grommets. Be sure that the air cleaner
backing plate is secured or that the necessary air cleaner
support brackets are used.
REPLACEMENT PARTS
Replacement grommets and flanges are available from your
local bike shop.
