OK going ahead and installing the piston in the engine block
We are going to first provide lots lubrication into the cylinder
and using clean rag we can wipe in
lots of oil. The cylinders have already been cleaned
and they are brand new cylinders that we are working with
on this particular engine.
So taking a look now at the correct position of the piston
during the install it is recommended by the manufacturer
that he piston faces cam side the engine, looking at the block
we have our lifter return galleries
so oil can run back down through here lubricate the pair the
lifter assembly as well as make its way back down to the bottom in the engine
this is also became gallery in here
so putting the person in the correct position and having the
the offset rod and in the correct position also facing
cam site based on manufacturer specs: the
for taking the piston dropping it down into the bore
using the trunk up it's going to guide it
so that we have in the correct position
lotsa lubrication the the
and tapping the pickup is going down into position shouldn't take much
pressure
I'm moving it to make sure that there is no find him during installation
and stopping right at the very top once it is installed
what are the biggest mistakes that technicians make during piston
install is trying to drive the piston all the way down to its position
in the bottom into the engine all we want to do is just be
inside and just slightly get the piston down from the top
I can turn the piston I know there's no binding
and it's a good install goodies now that we have the piston installed just below
the deck height
on the top side of the engine we want to pull the piston down
into its respective position in the bottom of the engine
they will continue to pull it down
until we made it directly to the rod
girdle but to last thing you can see we've got the engine rotated upside down
now for the instruction purpose
we've got our create Journal and now we're just gonna pull that meeting
connecting rod
up from the position and now it in the correct position for installing the cap
from the so taking a look at our connecting rod cap it's been cleaning
ready to go back into service now we have the engine bearing
into the best way to install these bearings is to use the paying
furnish a location-aware the bearing has to sit
we use our thumbs and to push it into position
checking that we have a little bit a crush
protruding on each side we want the center that crush with their fingernails
so that we can hear that we have a little bit sticking up
on both sides being for a little bit a boil on the ferry now
and again it's okay to touch a bearing surface when it is lubricated is on your
fingers are clean
but never touch a bearing surface if your fingers are dry cuz the assets from
your finger
create localized hot spying on that very so now we're gonna take a look at this
and we always want to go a lot
the Lark here's our lock here here's our lock here
this is used it's put together with what's called a
broach on this site and approach we on this side like people call it a key way
but to broach way where the broach the mail broached fits into the female
approach to lock it in the position that prevents any site movement on the cap
and premature failure or where the bear to installing the connecting rod cap
once the ride is up onto the rock journal
then we can install the cap lock to lock
making sure that we have the crack fit it
for the important factors to pay attention when you do the install
making sure that you equally torque both sides down
so that piece cast is being sweet
correctly between the two parting lines and if it correctly if they broke
and for the Seaway smoking up both sides
people using it now old the
and then using the correct torque go ahead
for the
the
so what are the best things to do is after doing the install
is to make sure one that we've got movement in the connecting rod which we
do
we've got side clearance in here so we can move it back and forth we can see
it we actually have that movement on the connecting rod
to get indication we have sufficient site clearance which would be measured
here
for also going to rotate the engine
to make sure that the engine rotates correctly
14 revolution to make sure that we have
the correct fit at the connecting rod
to the journal now in prior
video series we have an install
checked that we do on main bearings with vertical oil clearance
can we use plastic gauge the support that each one of these has been checked
in this would now have to be checked before it actually goes into service in
the manufacture speck on this one
is one 2/4 out and all the other ones came in around three thousand gonna
suspect that this will be at three fellow also want it is check
with ok with the piston assembly that we install
and what are the good things to do after the install
is to make sure that we don't have any marks or scoring on the insider that
cylinder
so we can far this engine around
then we could watch that piston come up to top
and the second one that's coming up with it
we call this our companions still there so we have number three and number four
together
we have number are one in six and we have number two
and five as companions so one would be on the power stroke or one is on the
exhaust stroke
compression stroke and powers for
so as we bring it up to the top it will bring it back down
you want to take a look in that cylinder
to see if there's any marks
that show an incorrect in stock we have lots of oil here
it chills that the rains are doing their job in this still there
but there is no marquee a boil trails or any scoring
and that is through every soldier in this particular engine
that tells us that the install was done correctly
because we don't have any markings on the inside that's all they're all
