all right wanted to show you guys this ls block before we get machine on it this is
already obviously been disassembled all the bearings stripped out of it has been
baked and blasted to make it look new this is what it looks like raw before
the machining processes that you will you will see shortly give me just a quick
just overview of this thing you can see it looks uh the bacon blast processes does a
pretty good job of making this thing look pretty much brand new this has got like uh
i think this is a 130 000 mile engine block so until it looks pretty good um so
i'm gonna get this thing set up and we're gonna deck it that's the first part of our procedures
and then uh we'll move on from there all right just want to walk through this
with you i got the block up here i still have to put the dial indicator on it and
square the deck um this bar goes through the mains i don't know how familiar you guys are this is a
kind of a older decking machine it is a clockmaster 85b by storm balkan
um so what this allows me to do is i put an indicator up here down or
from the cutter head from the cutting head here to the bar and run it along the bar and that ensures
me that the bar is level so by that i can then ensure that the deck if there's variance from
end to end that we know that that is true variance from it being square to the crankshaft it does not
square to the crank if there is variance there so once i get it to this point where it's on the bar
i roll the block uh this way or that way um to just adjust that axis
uh and then we cut it from there so all right walk you through that real quick i'm gonna get
the indicator up here c2 i'm gonna spray a little bit of oil on the deck and hit it basically with
a board with some sandpaper on it just to see if there's any super high imperfections um that
i can avoid with the dial indicator when setting the other axis there so i'm gonna keep working on
all right i wanted to try to give you guys a view after the first cut i pulled about a thou
off of it you can see the surface that's been machined in the service that has it you can
see the twist in the block as it transitions see that from where it was touching where it wasn't
this had four thou worth of uh rise in the back of it so this was fourth out higher that's why this
surface is all cleaned up and it had two thousand twists this corner was two thousandths low
here and you see how that fades into here i know it's kind of hard to see
but give you an idea so i'm going to keep making passes with this thing like i said
i think that was a thou or two thou from the low point um for from there so i'm going to uh keep
making passes here until it's all cleaned up and then i'll show you what it looks like when it's
finished
all right so here's the one side finished up it took six thousandths to get it clean and see it
looks uh good and consistent everywhere now um so i'm gonna roll the block over and cut
the other side the same sixth dial hopefully it will clean up in that same distance if it
doesn't and i have to cut it significantly more say seven or eight or nine foul then i will have
to come back to this bank and make sure they're both the same so we're gonna roll it over set
it up and i'm just gonna breeze right through that and cut it and show you when it's finished
so
all right got this one all decked it took seventh hour to clean this side up as opposed
to the six on the other side which for this uh this specific application is plenty acceptable
so i'm gonna get this thing off of here and uh stick it in the home and get rid of the size
of cylinders i think we're gonna go this thing doesn't have much wall uh wear in the cylinder
wall so i'm just going to start with some coarse stones we're probably going to go 10 over with it
um i'm going to mic it first just to confirm that so make sure we don't actually have to put it
under the boring bar and cut the cylinders but if we've only got to go 10 i can do that in the
home just fine so i'm going to get it off of here mike some cylinders up and stick it in the hole
okay i thought i'd give you one more shot of this before we stick at the home
uh unlike the cylinders what i'm looking for there is the biggest one and to determine if i uh need
to board if we can just go into the home these more modern ring packs uh the cylinders don't wear
like you're familiar with your your old five five sixty fours or sixteenths ring grooves
that the older engines came with these things uh for example this thing had 130 1440 k on it
the worst cylinder is three foul bag at the top and a thou big down in the bore so
honing this thing ten thousand very achievable and is currently my plan so i'm gonna get this
set up in the home and torque plates on it i'll walk you through that as well
you
