spots, creating little bumps on the friction<br />

surface. A grinding wheel cuts right<br />

through the hard spots.<br />

Although your flywheel appears to be<br />

all right, it should still be cleaned. For<br />

instance, the clutch friction surface will<br />

be shiny, or may have some deposits on<br />

it. <strong>To</strong> help it and the clutch, use fine-grit<br />

sandpaper to roughen the surface. This<br />

will remove resin deposits left from the<br />

clutch disc too. Follow the sanding with<br />

a good cleaning with non-petroleumbased<br />

solvent such as alcohol or lacquer<br />

thinner. This will remove any oil deposits.<br />

Give the same treatment to the pressure<br />

plate if you are planning to reuse your<br />

old one.<br />

Clutch Release Bearing-There are two<br />

rules when it comes to the release bearing:<br />

replace it if you are replacing your clutch.<br />

The next rule is replace it anyway. The<br />

relative cost <strong>of</strong> a new bearing and the<br />

amount <strong>of</strong> work it takes to replace it now<br />

as opposed to when your engine is back<br />

in should give you a good idea as to what<br />

you should do. Regardless <strong>of</strong> whether or<br />

not you replace your bearing, fdl the<br />

bearing-hub-bore groove with grease.<br />

Don't overdo it because too much grease<br />

causes clutch failure if the grease gets on<br />

the clutch disc. Use moly grease to lubricate<br />

the bearing hub and the wear points<br />

on the release lever, then replace the<br />

bearing.<br />

Engine Plate-Whether you have an automatic<br />

transmission or a standard transmission,<br />

there's an engine plate to install<br />

before the flywheellflexplate can go on.<br />

Because it depends on the bellhousing or<br />

converter housing to hold it to the engine,<br />

it'll be constantly falling <strong>of</strong>f while you<br />

are trying to install the flywheel/flexplate.<br />

It can fall away from the block and down<br />

between the block and flywheel/flexplate<br />

while you're trying to bolt the engine to<br />

the transmission. Here's a tip: Apply a<br />

thin bead <strong>of</strong> 3M weatherstrip adhesive to<br />

the rear face <strong>of</strong> your engine block to hold<br />

the engine plate in place. Install the plate<br />

over the locating dowels with the starter<br />

hole to the right. Hold it in place for a<br />

minute or so to make sure the adhesive<br />

gets a grip on the plate.<br />

Flywheel or Flexplate-Make sure your<br />

crankshaft-mounting flange is clean and<br />

free <strong>of</strong> burrs, particularly in the case<br />

where you will be mounting a flywheel to<br />

it. This can cock the flywheel, causing it<br />

to wobble, which will lead to clutch and<br />

transmission problems.<br />

Install the flywheel or flexplate using<br />

the 6 grade8 bolts and a drop <strong>of</strong> Loctite<br />

on the threads. When locating the fly-<br />

wheel or flexplate, rotate it on the crankmounting<br />

flange until the mounting holes<br />

line up. They are drilled so the flywheel/<br />

flexplate can mount in only one position<br />

so the engine will be balanced correctly.<br />

Don't panic when you see the holes don't<br />

line up the first time. Snug the mounting<br />

bolts, then torque them to 75-85 ft.lbs.<br />

Position the crankshaft so the marked<br />

converter-mounting hole is at the bottom.<br />

Mounting the Clutch-As soon as the flywheel<br />

is mounted on the engine, it's<br />

readv for the clutch. Remember to avoid<br />

touching the friction surfaces-pressure<br />

plate, flywheel and disc. Crease on the<br />

clutch surfaces causes bad things like<br />

grabbing or slipping, so be careful not to<br />

touch the operating surfaces.<br />

<strong>To</strong> mount the clutch, you'll need a<br />

tool to align the clutch disc with the center<br />

<strong>of</strong> the crankshaft while you are<br />

tightening down the pressure plate. An<br />

old transmission input shaft works well,<br />

or special inexpensive tools are available<br />

for doing this job. Clutch-alignment tools<br />

are available at most automotive parts<br />

stores.<br />

Although you can probably handle<br />

this job yourself, a friendly third hand<br />

comes in handy. <strong>To</strong> install the clutch,<br />

hold the pressure plate and the disc against<br />

the flywheel while starting at least two<br />

pressure-plate bolts and their lockwashers.<br />

Make sure you have the disc installed in<br />

the right direction. FLYWHEEL' SIDE<br />

should be indicated on the disc, however<br />

if it's not, the spring-and-hub assembly<br />

goes toward the transmission.<br />

With the bolts holding the pressure<br />

plate up, install the input shaft or clutchalignment<br />

tool in the clutch disc and center<br />

it in the pilot bearing. You can now<br />

start the rest <strong>of</strong> the bolts. A word <strong>of</strong><br />

caution4on 't tighten any <strong>of</strong> the bolts all<br />

the way. This will result in junking the<br />

pressure plate because it will bend the<br />

cover. Tighten each bolt a couple <strong>of</strong> turns<br />

at a time. Go around the pressure-plate<br />

bolts several times until the cover is firmly<br />

against the flywheel. Remove the alignment<br />

tool and torque the pressure-plate<br />

bolts to 12-20 ft.lbs.<br />

Spark Plugs-If you haven't already done<br />

so, install a new set <strong>of</strong> spark plugs. They<br />

will be well protected in the heads, particularly<br />

with the exhaust manifolds installed.<br />

Remove the old plugs you installed<br />

to keep the cylinders clean and dry, and<br />

replace them with new ones. Check and<br />

set their gaps first. <strong>To</strong>rque all the plugs to<br />

10 ft.lbs. except for the one in number-1<br />

cylinder. Leave it loose.<br />

Engine Mounts-Engine-mount designs<br />

vary according to the engine and chassis<br />

they are used with, however their basic<br />

design does not change. All use a single<br />

through-bolt for ease <strong>of</strong> engine installation.<br />

Some mounts are not interchangeable<br />

from side to side, so make sure you<br />

identify which is which. R.H. or L.H.<br />

should be stamped on the mounts somewhere<br />

if they don't interchange. Also, I'm<br />

sure you remember that some installations<br />

require that the engine-mount insulators<br />

be removed so the engine can be removed<br />

and re-installed. This is the case with 460<br />

truck installations due to the tight fit<br />

between the firewall and the transmission<br />

bellhousing or converter housing. Once<br />

the engine and transmission are connected,<br />

you can re-install the insulators.<br />

INSTALLING THE ENGINE<br />

There's not much more you can do<br />

with the engine out, so the big moment<br />

has come. Attach a chain or cable to the<br />

front <strong>of</strong> the left head and the rear <strong>of</strong> the<br />

right head or, better yet, make use <strong>of</strong> the<br />

lifting lugs at the exhaust manifolds. Now,<br />

if you have an automatic transmission,<br />

make sure the marked hole on the flexplate<br />

is at the bottom. The marked stud<br />

on the torque converter goes at the bottom<br />

too. It won't take long to find out<br />

how important this is if the converter<br />

won't engage the flexplate.<br />

Lift the engne and check to see that<br />

it's level side-to-side and slightly low at<br />

the rear. Set the engine down if necessary<br />

and adjust the chain until it's right. This<br />

The moment we ., ,en waiting for,<br />

installation time. While Louis controls the<br />

engine, notice flexplate mark positioned at<br />

bottom, ground strap attached to the right<br />

head, all loose ends are up out <strong>of</strong> the way<br />

and wiring harness is installed. Engine can<br />

be lowered while care is taken to make<br />

sure everything clears. You can't see it, but<br />

there's a jack under the transmission to<br />

bring it up to where it will engage with the<br />

engine.
