Crank pulley: 1985 Accord

I'm trying to replace the timing belt on a 1985 Accord. The bolt on the
crank pulley won't budge. Broke a Craftsman half-inch socket extension
in trying to loosen it. Heated it up with a torch. Nothing.

I have an air impact wrench and plan to borrow a compressor from a
friend to try that next. Before I do, I need to verify the following:

Is the bolt on the crank pulley a left-tightening or right-tightening
bolt?

 

Right-tightening ( = right-handed = most common) thread. So turn Counter
clockwise to loosen.

Did you put a jack underneath the extension (at about the end of the extension)
to support it vertically?

What are you using to hold the pulley in place?

If you need ideas, see:

By all means, turn the bolt counter clockwise to loosen. Note that if your
impact wrench doesn't get it, then you'll need a tool such as

loosen it with a breaker bar. I was able to loosen mine on an '88 Civic
with a 24" breaker bar.

dude, i just started doing my timing belt yesterday on my 87accord, i had
the same problem. what i did was i used a bicycle tool called a lock ring
wrench, its shaped like a hook and fits in the holes in the pulley. i had
the end of the lock ring wrench up against the frame of the car and used a
1/2 snap on wrench, i had to force it off with my foot it was so tight. but
what helped me most of all was penetrating oil. just soak soak soak it in
penetrating oil, let it sit for an hour and apply more oil every 10 min,
thats the best way to avoid breaking the bolt. if u reak the bolt you can
basically end up having to replace the crank shaft.

 

I concur with what has already been written. On an 88 Accord, I used the
large screwdriver into the ring gear procedure and had a 24 inch breaker bar
that I could jump on to break it free. I tried the air wrench with 320 lbs.
of torque but that did not budge it. By the way once you get that off, you
are going to need a puller to get the pulley off as it is pressed onto the
crank. I noticed a white powder on the threads of the bolt so not sure if
someone had dressed the threads with some kind of compound the last time it
was off.

 

i didnt need a puller on my 87 i just worked it loose by rocking it back and
forth, i think the penetrating oil loosend it up. I got this rusty spray can
of penetrating oil and it saved me so many times.

 

I have 2 impact wrenches (actually more than that but for this story) a
standard 1/2 for general work including 985 of the crank bolts and a 3/4 for
the 25 of the crank bolts.
