Default Crankshaft Bolt... Ugh

My weekend project was to change the timing belt, balance shaft belt, tensioner, and water pump... My weekend is half over and I still don't have it taken apart.

I am looking for any tips and/or advice on removing the crankshaft bolt. I have looked around here and found some different things, but so far I'm not having any luck. I saw someone post that they bolted a chain through a hole in the pulley to keep the engine from turning... My pulley has no holes.

I haven't been able to find anywhere I can get a screwdriver or anything into a hole in the flywheel to hold it.

I have an electric impact wrench, but it doesn't have the ***** to crack it loose. I don't have a suitable air compressor to use an air impact wrench.

Any help would be greatly appreciated

Doing it with no compressor, oh boy. I would take another jack with a board or block of rubber and jack it up against the pulley (not too hard) then get piece of pipe to put on my ratchet for leverage.

Roader,
It does have a hex, where do you get the nifty tool?

That tool is the correct way to do it.

The incorrect way is to jam a screw driver in the flywheel either in the hole under the rubber grommet on the front where the engine meets the transmission. Or under the car where there is a flimsy removable cover that covers the flywheel.

Even w/ the handy crankshaft restraint tool, you will also need two, good 1/2" x 18" breaker bars, 1/2" x 16" of extensions, a jack stand, 19mm deep socket, and a cheater pipe (3-4 ft) to go over 1/2" breaker bar to gain enough leverage to break the bolt.

Breakout torque is something like 600-800 ft-lbs. Heating crankshaft bolt head w/ propane for 5 mins may help reduce breakout torque. It did help me w/ ingersol 1/2" air impact tool.

good luck

This is what I used ( 96 accord )

Powerbuilt 648796 Honda Crankcase Pulley Removal Tool - Amazon.com Powerbuilt 648796 Honda Crankcase Pulley Removal Tool - Amazon.com

you will need two 1/2 breaker bars. I then put a 6 ft 1 inch pipe around the breaker bar and with all my weight 180lbs rocking a bit on it, it finally broke free. I also put long pants, heavy coat, safety glasses on in case I went flying when it broke free.

I also put the spare tire on for stability with the wheel turned slightly to make room for the extension. Then used a jack stand to support the extension and pushed and pushed and pushed.

Thank you all so much, I am going to see if an Auto Zone or Advance Auto Parts in my area has one of these tools in their loaner tools, and borrow a piece of cheater-pipe from my dad... I have a feeling it's going to make the rest of this job a lot easier, thank you all again

wear some old padded clothes, when it brakes free you'll go flying
