Look over http://tegger.com/hondafaq/cranktool/index.html (and the next
section about getting the belt on right!)
The socket is a normal 19 mm socket, but be aware the job is much easier
with an impact driver, and that requires an impact socket (black). With the
holder, a long breaker bar and a lot of manly muscles the bolt can be broken
loose, but your manly muscles will be sore when you finish.
I should mention - if you can get ahold of an impact driver and socket (like
by renting them) you won't need the holder. This is a case of "bigger is
better" on the driver, though; 400 ft-lbs is about the minimum. I used a 500
ft-lb pneumatic driver with the regulator right at the tool when we did my
son's Acura, and it struggled a bit.
Don't listen to anybody who tries to tell you the bolt can be loosened by
putting the handle of a socket wrench on a jackstand and hitting the
starter. The engine turns the wrong way 8^O
thank you. My problem is finding the tools i listed. Can anyone tell me
where i can find the TOOLS; other than at Honda?
Holder handle 07jab -001020A ,

You don't need any of that stuff.
Rent a DeWalt electric impact wrench from any industrial rental place for
about $25 per day. This thing will spinn the bolt off with so little effort
you'll think you're in paradise.
The black 19mm deep socket can be had at any hardware store for about $10.
you'd think, but in practice, it's very hard to get it right if there's
too much elasticity. friction of the bolt interfaces is uneven - the
more elasticity, the more opportunity for friction to momentarily lock
movement. to put it another way, /you/ may be turning the wrench
smoothly, but with excess elasticity, the crank is not resisting smoothly.
Resistance is quite regular and smooth, actually. Drivetrain lash is
negligible compared to the amount of compression undergone by the clutch
friction disc springs.
If you have a helper step on the brakes, you feel the lash being taken
up, then you feel the clutch springs compressing. It's fairly
predictable, and amounts to having a really long extension on your
Now if you had an automatic, how would you hold the pulley still for
bolt-tightening without a proper pulley-holder tool? That would be
tough, wouldn't it?
When I did my wife's (automatic) Tercel's timing belt last year, I had
to fabricate a simple tool to hold the pulley still. It's just a three-
foot length of steel with two holes drilled in it.
the springs are a good point - i'd overlooked that!
technically though, you can't rely on long elastic paths of travel for
this stuff. if you look at strain gauges when torquing bolts, it's
actually a series of lurches. springiness in the system allows more
deflection per lurch, and will often omit the final stage. that's why
you have torque extensions for impact tools - you can apply big torque
at one end, but the other end won't over-tighten. correspondingly,
"stiff" pulley bolts are devils to manually loosen with 1/2" extensions,
but they come off easy with 3/4" tools. same applied torque in either case.
Nice tool! Can you make me one? ;-)
How about putting some thin nylon rope in the number 1 cylinder as it
comes up on compression stroke? Kind of a PITA, but it works.
I have heard of people using an impact wrench to tighten the crankshaft
bolt. Kind of scary if you ask me...
I only tried that once, on an old Toyota. It scared the bejeebers out of
me - for some odd reason I didn't expect the front of the car to rise
several inches when I bumped the starter. And that was a succesful
Kinda like propping a small plane and finding the throttle was open a bit
too far and the the plane wasn't tied down - my brother did that with his
Cessna 140 :-(
It must have taken some muscle power to rotate the wheel. I suppose they
used a fairly high gear?
