How To Rebuild Your Ford V-8 351C-351M-400-429-460.pdf - Index of

To ease future repairs, apply some antiseize
compound to the damper ID. Oil its
seal surface and you're ready to install it.
use two gaskets, one between the pump's
cover plate and the pump, and one
between the water-pump assenlbly and
the front engine cover. After you've installed
the pump's cover with its gasket
and sealer, install the assembly to the
front cover, again with the gasket and
some sealer.
Install the Front Cover-Lubricate the
fuel-pump cam with some moly grease
and wipe off any excess oil from the
block's front-cover mounting surface. Use
thinner to get it really clean so the sealer
will seal.
Two dowel pins in the 351 C, 351 MI400
block locate the front cover whereas the
4291460 cover must be centered on the
crankshaft using the damper spacer. If it
isn't, the damper will probably end up
off-center resulting in uneven seal loading
and an oil leak.
Center the aluminum cover by installing
the front cover loosely. Using the
spacer installed on the crank nose and inserted
in the cover seal for centering,
secure the cover to the engine. Torque
front-cover bolts 12-18 ft. Ibs. for both
styles of front covers.
A tip is in order here if you have a
4291460. Now's the time to install the
thermostat-bypass hose. Regardless of
age, I always replace it because it's so
much easier to do now than a month or
two years later. It's also easier to install
now than after you have the water pump/
front cover in place. You'll need a 518-inch
hose approximately 2-314-inches long.
This is a bit longer than required, so hold
your water pump and cover in place, then
measure exactly how much length you'll
need. Measure from the front of the intake
manifold to the back of the water pump.
Torque crankshaft damper bolt 70-90 ft.lbs. Keep crankshaft from turning by using a
screwdriver between the block and one of the crank's counterweights. If the oil pan is in
place, a bolt in the damper and a screwdriver can be used to hold the crank from turning.
After trimming the hose to length, install
it, with its two hose clamps, on the manifold.
You can now fit it to the water
pump as you install it and the front cover.
Install the Damper-Apply anti-seize compound
to the damper bore. It acts as a
lubricant during the installation so the
crankshaft and damper won't gall. It also
helps in the event the damper has to be
removed at a later date.
Lubricate the front-cover seal. Install
the damper after making sure its key is in
place. You'll be installing the damper's
bolt and washer for the last time. Use it
to pull the damper on, and torque it 70-
90 ft.lbs. You'll find that you can't beginto
apply this much torque without turning
the crankshaft; so use a large screwdriver
to keep it from rotating. Put the screwdriver
between the bottom of the block
and the front of the counterweight.
OIL PUMP & PAN
Now's the time to seal the bottom of
your engine. If it's not already upside
down, roll your engine over on its back.
Before installing the pan, you'll have to
install the oil pump and its driveshaft-it's
just a tad difficult afterwards.
Oil-Pump Pickup-If you have a new oil
pump or if you removed the pickup from
your old one, you'll have to install the
pickup before putting the pump on the
engine. Pickups are not included with
new or rebuilt pumps.
The 4291460 pickup tube press-fits
into the bottom of its pump housing. To
remove the pickup, lightly clamp the
pump in a vise. I clamp it at the mounting
flange. Simply rotate the pickup and
gradually work it out of the pump body.
A 351C or 351Ml400 pickup can be unscrewed
from its pump. Just remember
its position so it can be installed correctly.
Rather than using a common punch, a
better tool can be fabricated from a short
piece of 314-inch pipe. Using your hacksaw,
remove a 2-inch section from one
end of the pipe like the one pictured.
You'll now have a tool which can bear on
180' of the pickiip-tshe bead. Consequently,
the chance of pickup-tube
damage is considerably reduced. Position
the pickup at a 45' angle to the pump so
it will be centered in the oil pan. You can
make final adjustments after installing the
pump assembly.
A 351C or 351Ml400 pickup should
, be installed so it will be level when in
place on the engine, or parallel to the
mounting flange. Without using sealer,
thread the pickupsinto the pump housing
and bring it around into position as it
tightens. Again, make final adjustments
once the pump assembly is installed.
Install the Driveshaft-l always replace
the oil-pump driveshaft because of its
critical function. However, if you plan to
reuse your old driveshaft, look it over. If
there is any appreciable wear other than
the shiny spots on the drive-sides of the
hexes; replace it.
With the littie Tinnerman collar-the
stamped-metal ring-pushed down over the
shaft and your engine on its back, install
your oil-pump driveshaft. Insert the end
of the shaft with the collar in the oilpump-shaft
bore. This collar performs a
very important function. It prevents the
shaft from being pulled out of the oil
pump when the distributor is removed.
The importance of this feature can be
fully realized by those unlucky individuals
who removed the distributor only to hear
an ominous clunk in their oil pan-the oil-
