Problem changing timing belt on 89 Civic

I tried to change the timing belt on my 89 Civic, I got as far as the
crankshaft flywheel/pulley but the nut that secured it to the
crankshaft is so tight that no matter what we did, me and my friend
can't get it to loosen, does anyone have any idea how to do this?

Is it one of those bolts that has a reverse thread? I did not try that
for fear of tighten it even further. Also the space to stick a ratchet
in is VERY narrow, what could be a better tool to use?

Any idea will be very much appreciated. Thank you all in advance!

 

Welcome to the very first and most popular Honda FAQ question!

I highly recommend the electric impact wrench.
DeWalt has upped the torque to 325# from 250# since I
wrote that page, and it's a real winner.
See a pic of it here:

No compressor needed!

 

i otoh recommend the pulley wheel holding tool and a 3/4" drive breaker
bar. scroll down tegger's page for pics.

Last time I tried to do the timing belt on my '87 Accord, we used a breaker bar
with a 4' pipe and even bouncing my 250+ weight on the end of it wouldn't break
the bastard loose. Also tried both electric and air impact guns, along with
lots of heat (plumber's torch), all to no avail...

 

that's why i use 3/4" - the bolt just cracks loose every time.

 

Thank you everyone, your comments have been very very helpful! You guys
have got to stick around this site!

Your help have been very much appreciated.

 

3/4" what? Socket? Grapplegrommet? Penis?

 

Two 1/2" 2ft breaker bars, like the ones from HarborFreight.com for
$9.99 each on sale, 20" Craftsman extension, along with a 4ft cheaper
pipe can loosen a V6 crank bolt. It should do it for you too. Wear eye
protection just in case. Just when you think it's impossible, a loud
pop and it's loose.

You don't live in the rust belt, do you? Think Honda changed the
direction of rotation on some engines. So check first.

 

Yes they ARE very difficult to remove.

Here is yet another tool to help:
