new to honda
thanks for help

Right. Which vehicle?

Whoa. Tegger's site has gone commercial.

Either that or someone's copyrights are being ethically
violated.

 

Someone once told me thre was only 1 or 2 reverse threads on hondas.
one of which is somewhere in the steering pump i think. but i have no
idea. Crank should be standard thread. It's just a SOB to lock the
pulley down and get enough leverage to break it.

 

you probably have to get some heat
to go some part store and use MPS gas
they come in small bottles like for propane they use for the pumping
but it is a yellow colour can

or just use oxy and acle if you gots ..
remeber heat it up then let it cool down on its own for like 15 mins
then try it

 

don't do that! you'll ruin seals, the belt [if you're not replacing it]
and possibly even the temper of the steel. not good. the bolt comes
off with the right tools, namely air tools, or if using hand tools, the
correct pulley wheel holder and a 3/4" socket set. [ordinary 1/2" sets
flex too much.]

 

normal r/h thread, but these things self-tighten, so they get real hard
to get off. go to tegger.com and check out the pulley wheel holder
tools - they make all the difference. also consider using a 3/4" socket
set rather than normal 1/2" - the bolt is real tight and the wind-up in
the 1/2" set gets a bit scary and hard to control. or use air tools -
/much/ easier!

 

The long Craftsman 1/2" flex handle will do it. Agreed on the seals. Don't
heat anything up unless you want to wreck stuff.

Right, bigger is often better but also not essential nor
economical. A 1/2-inch drive set worked fine for my 91
Civic. The 3/4-inch drive set of tools will set a person
back around $75 or more. (Two 8-inch long, 3/4-inch drive
extensions by themselves will run over $50.) Plus, the only
place that has a good stock of 3/4-inch drive tools is
Sears. Harbor Freight, Pep Boys, Home Depot and the like do
not carry much, if any, of this size drive.

Of course, if one jumps up and down on the end of the
breaker bar or its extension, as a certain person here is
reported to have done, then all bets are off as to the
safety of the tools, the crankshaft pulley, and the person.

Use a long extension to get the torque with as little force
as possible applied to the end.

Lastly, arranging with one's favorite local mechanic to
break the bolt free with an industrial strength impact
wrench for the measly sum of say $15 is often the preferred
quick fix here.

 

in terms of sheer force, sure. but it's much safer to go the 3/4"
route. there's almost /no/ wind-up, so when the bolt lets go, it just
unscrews rather than suddenly dissipating all that stored elastic energy
from the tool in potentially destructive ways such as slipping,
cracking, etc. sure, the tools cost a little more than just struggling
with your existing tool set, but:

1. they're guaranteed to work. yes, a sears breaker bar is guaranteed
in replacement in the event that it fails, but that's just the issue,
it's not 100% certain to shift the bolt and it might fail. the 3/4"
absolutely won't. trust me on that one.

2. the 3/4" stuff is still a good deal cheaper than buying air tools or
even an electric impact wrench [that may hot have sufficient torque].

3. once you have it, you'll be surprised how often you go back to it!

 

napa, of which there are a large number here in ca, carry a full line of
3/4" tools. and they usually have much more stock than my local sears.

i've lightened up my view on using an axle stand as a fulcrum. i still
think that when doing this job with the 1/2" tools, it's /way/ too
dangerous because there's *huge* elastic distortion before the bolt
gives. but with the 3/4" tool however, the wind-up is essentially zero
and the bolt just unscrews. in that situation, the use of a fulcrum,
while not ideal, is quite benign.

kinda, but i swear, with less than 30 miles between swapping out a water
pump [pulley bolt], and determining the engine was good enough to do the
rest of the job properly [pulley bolt] on my crx, that sucker was full
tight and easily over 300 ft.lbs again. if you have someone break the
bolt for you, drive /slow/ and keep it close to home.

Snap-On, of course, has them;

but you're right, they're expensive as hell

 

I imagine Napa Auto Parts has them through special order as
well.

 

they're all laid out and in stock at any napa store.

 

Jim:
How big of an impact wrench would one need - can you give an idea in
foot pounds of torque - or would most 1/2" and any 3/4" impact do the
job?

 

well, i agree with estimates of release torque at about 300ft.lbs, so
most 1/2" air impact wrenches should shift that. assuming there's
sufficient air of course - a small compressor won't allow the impact to
make rated torque.

 

You don't think it's possible to hurt yourself with a 3/4" breaker bar?

About a fifth of the windup, to be exact. So where the
1/2-inch drive will give around 45 degrees of windup (give
or take, and at the torques we're talking about), the
3/4-inch will give about 9 degrees.

But that's nothing. Buy a 1-inch drive set, and you get
about 1/16th the windup, or only about 3 degrees. The 1-inch
drive setup is extraordinarily safe. It may cost you $200
all told, but you'll be safe.

It's much safer not to do any of one's own work on a car as
well.

Your suggestion is overkill. Just like your overhyping of
that $100+ Honda ball joint separator when a $20 tool (or
arguably a large hammer, for the more experienced) will work
fine. Just like your hysteria over people who use hood pins,
because a cyclist might end up on the hood.

Unless you've been misusing tools and jumping up and down
again on the end of one of those 1/2-inch breaker bars, the
reports of their breaking for this application have to be
far and few between, if any. I have never seen any.

Maybe because you indulge your habit of breaking pulley
bolts free at local junkyards, you prefer the 3/4-inch drive
set.

You mentioned hood pins.

I don't know why so many people say men are less artistic
than women. I think they just need the right "canvas."

Jackson Pollock, look out.
