CRANKWALKED? 7-bolt teardown 1080HD
Now this is a story all about how
My bearings got flipped-turned upside down
And I'd like to take a minute just sit right there
And tell you how I used to mix and burn my gas and my air.
In RVA suburbs born and raised
On the dragstrip is where I spent most of my days
Chillin out, maxin, relaxing all cool,
'n all shooting some BS outside with my tools
When a couple of guys who were up to no good
Started running races in my neighborhood
I heard one little knock and my rods got scared
And said "You put it in the garage until you figure out where..."
I Begged and pleaded that it not be that way,
But it didn't want to start and run another day.
I kissed it goodbye, because the motor punched its ticket
I got out my camera, said "I might as well kick it."
Crankwalk yo this is bad
Drinking metal shavings from an oil pan.
Is this what the rumor of crankwalk is like?
Hmm this won't be alright
But wait I heard knocking, grinding and all that
Is this the type of failure that should happen to this cool cat?
I don't think so, I'll see when I get there
I hope they're prepared for this video I share.
Well I pulled all the bolts and when I came out
There were chunks in my fluids in the pan and they drained out
I aint all depressed cause I seen this before.
I got my books and my wrench and we'll do it once more.
I sprang into action like lightning disassembled
I whistled while I worked and my hands never trembled
If anything you could say that this bling is rare,
and when I saw what broke I stained my underwear.
I turned off the air compressor 'bout 7 or 8
And I yelled to crankcase "Yo holmes, smell ya later"
I looked at my internals they were finally there
To sit on my workbench and stink up the air.

Here's the 48,000 mile-old 7-bolt I blew up summer 2011 after over 150 drag
passes, a half dozen Dyno sessions, 4 transmissions,
3 clutches and 10 years of hard all-weather use.

Inline Four - Precision Engine Balancing
Precision Engine Balancing is something often overlooked, especially by
"backyard" or "inexperienced" engine builders. This video showcases not
only engine balancing of a Honda 4 cyl. rotating assembly, but at the
precise specification that Inline Four holds its engine building standards
to. After watching this video, you will not look at engine building the
same and will want the best for your engine. "Do it right, or don't do it
at all!" =Brandon...out!
Many of you have seen this one before. I apologize if bringing it back
Domestickilla gave me a crankshaft, and it's a nice one that I want to
clean up and use again. You'll be seeing a lot of it and because of this,
this video deserves to be here. I fixed what I broke, and this was my

Crankshaft grinding Eagle 4340 Forged SBC Crank
CPMotorworks, Inc of Janesville Wi shows what is needed to repair poorly
ground journals of an aftermarket crankshaft. We were able to remove .002"
from these main journals to correct the hourglass shaped journals that were
the result of a poorly dressed grinding wheel and over-polishing.
Blueprint 104 - The Crankshaft
It's important to know what you've got even before dealing with the
machinist. If you want to inspect a crankshaft, this is how you do it. I
detail the process of removing the crank and what to measure. All
specifications in this video are illustrated with a 6-bolt 4g63 turbo block, but are all actually the same for
7-bolt engines with the exception of the rod widths.
