Re: my civic and its timing belt
Sorry I didn't get back to you.
A 3/4 air gun sets around 750 ft lbs I believe. It was a used one on the snap-on truck, a central pneumatics I believe. A larger gun has bigger hammers, and doesn't beat you up as much as a 1/2 inch gun. more force goes into the socket. Working in a auto shop, we occasionally get the stubborn bolts, and on occasion have tried everyone's gun in the shop. Sometimes some will work where another one won't. the 3/4 has always worked. Once the shop downtown from us called asking if I still had such a gun, they were fighting a crank bolt for several hours with a huge compressor and a bunch of 1/2 inch guns. No success. Big Bertha did the job with no problem I wouldn't use heat on a crank. See if you can find a big gun and give it a try. Of coarse air supply is important, but usually on a small compressor, the initial trigger pull and the first 5 seconds will tell you if you are going to win.

Re: my civic and its timing belt
Thanks, Steve. That is interesting about the bigger hammers. I can't argue
with results! I've ordered a holder tool for the pulley to stiffen up the work. I'll try the 500 ft-lb, 1/2 inch drive and at-tool regulator with that. At least there is no hurry. The rental place also has a 1 inch drive pneumatic besides the 3/4 inch drive electric. There are options.... As my son mentions, this pretty much answers the question of whether the belt has been replaced before!

Re: my civic and its timing belt
As many timing belts as I have done, this "tool" your getting seems like a
waste of money and time to me. The only time I've needed to hold the pulley was when there isn't enough room to fit a gun in (Nissan 300zx last week) A good gun WILL remove the bolt. If the gun you have didn't work try a bigger one. Also use as little extensions as possible, they reduce torque. preferably a socket on the gun, then step up until you just have the reach you need. -- Stephen W.

Re: my civic and its timing belt
This bolt is indeed devilishly tight, and I'm looking for all the benefit I
can get. It makes sense to backstop the pulley or crankshaft as firmly as possible in order to prevent the impact from being distributed through the power train. In any event, the tool is on its way. There must be a reason Honda made the fitment for the tool and prescribed a tool to use. If my gun can't get it with the tool, I'll rent a bigger one. But I'd think an honest 500 ft-lbs delivered to the bolt-crank junction should do the trick. It would be interesting to know what torques there actually are on these 10 year old factory originals!

Re: my civic and its timing belt
Okay! With the 500 ft-lb 1/2 inch drive impact, 130 psi in the hose and a 90
psi regulator at the tool, and a holding tool on the pulley, it came loose. I didn't see if it started moving with the first 5 second burst, but the second burst got it backing out freely. We also worked on it when the engine was slightly warm, if that made a difference. My guess, drawing on your experience, Steve, is that many of the crank bolts can be loosened that way. (This one may have been at 495 ft-lbs! The torque spec is 130 ft-lbs, but that isn't what it was.) There is a definite possibility some will need more than my setup would give, but I do feel the $25 holding tool was worth the cost. When times are tighter I might not feel that way.
