Hi i,m changing the timing belts on my son's honda acord Lx. It has the 2.2 4 clylider engine. I was a mechanic by trade. Never worked on this engine before. I have a repair manual. Everything was going great until I went to remove the Lower Harmonic pully bolt. I sprayed it with penatrating oil. Grabbed a old belt rapped a old belt around the out side and tried to remove the bold with my impact gun. it won bugge. I.m trying to remove it counter clock wise, is that correct. Is there any trick to this. I sprayed it with the penatrating oil again and will let it sit uver night. Do you have any sugestions for me. Am I doing some thing wrong.. I did line up all the timing marks befor i did this. Any help would be greatly appreciated. River

yeah get an impact gun...or a very long breaker bar....you are doing it right the bolt is just a B!!@$# to get off

 

Yep they are mighty tight. I use a 1/2" Nitrocat Impact that will back em out. There is a special tool to hold the pulley so that you can use a long breaker bar also. Make sure to lube threads with light oil when re-installing....208ft.lbs. is the torque spec.

nope, it's 181ft lbs.

This is the tool I use for removing the crank bolt.

It's worked great for me.

 

/\ thats the same tool i bought I used my 1/2 drive break over bar+ long cheater bar. Keep trying it will come off, It makes a loud crack when it breaks loose.

 

yep, it sounds like you broke the bolt.

Here's a couple pictures of what it looked like when we did a timing belt on a friends 94 Accord EX.

 

Broke the bolt? i didnt , i said it makes a loud crack/snap sound when it breaks loose.
Your pics are the same way i broke mine loose. Same length cheater bar

 

i broke all my 1/2inch exstensions trying to get mine off (thank god they were crafstmen twisted one like a candy cane)for the first time and didnt get it with a 1/2impact(750lb ft) either ended up having to use a 3/4inch breaker bar and my 250lb uncle and me on it

 

Wow holy crap, I was using my impack suppose to have 250 lbs of torqe. I put penatrating oil on it and im going to up my compressor pressure abit , I' ll try that in the morning. Thanks I'll let you know if it work, other wise I see if I can borrow that tool. Thanks River

 

I stand corrected !

no no, I'm not saying you broke the bolt. I'm agreeing with you about the sound it makes when it breaks loose. I'm saying it sounds like the bolt breaks when it breaks loose because of the snap/crack sound it makes.

 

can someone show me the whole procedure of changing the timing belt? (with pictures possible )

thx u so muchie

 

can i get a part number or the name of the part that holds that harmonic balancer

 

http://www.amazon.com/OTC-4731-Crank.../dp/B000L7O4FE

among others. may be cheaper other places. i got a used OTC one on ebay for about $35, but there aren't many OTC's listed usually. OTC is a good pro brand.

summitracing.com sells them on ebay.

That's the updated version of the one I have and used in my timing belt write-up. I've used it multiple times and have also loaned it out to people to use and it's held up just fine.

 

thanks for the help our metal fab class is going to try to make the pully holder seems pretty easy just 6 pices of flat stock and a handel.

 

Or if you search (google) there are some sites that talk about using pipe fittings....thought about this for the 95 years ago, ended up just buying the tool.

But, if this is in a school setting then, yes let the class work on something real life. That is always the best learning...hands on.
