I just can't do it.

I have a JDM d15b engine in my garage and I figured I should replace the timing belt and water pump before I throw it in my car.

The damn bolt holding the crankshaft pully on won't budge.

At first I stuck a prybar and a screwdriver in the hole to offer some sort of resistance. The end result was a bent screwdriver and prybar.

Today I hooked up the air tools to try to move the thing. Nothing.

Does anyone have a secret (maybe with pictures?) on how to get this thing to budge? My next plan will be to take it to a mechanic and just have him do it all for me.

 

Yes, I've done this several times. Get the correct size socket I believe it 19MM and put it on a breaker bar. Now hear is the trick. I then took a 4 foot steel hollow tube that fit over the breaker bar and now you stand on it and it and jump up and down. The tube I used was actually for mounting an old TV antenna to the roof of a house but hey it works. Guaranteed, oh and it’s a standard thread not reverse. Oh and one more thing. You will turn the engine over so you have to take a big *** screw driver and jam it in your your fly wheel to keep it from spinning after you've removed you clutch inspection cover. It's probably about 150 - 200 ft/lbs of torque need to bust this.

 

Get some one else on the other side with a flywheel turner and go opposite ways. You both do half the work to get the bolt free. Easy as hell this compared to doing in the car. Trust me, I got in a recent fight with my car over this. Check the dent in the driver's side fender of my car on pg 50 of the pics thread, lol.

 

what kind of compressor and gun are you using... also how much psi is in your tank...

the right impact gun and tank will do the job

 

It took me about 2 days to get mine broken loose, and the engine was sitting on a pallet right infront of me. I cannot even imagin trying this with the engine in the car. Anyway, I basically had a 3 foot breaker bar and had to stand on it and jump up and down.

 

lol. always gives me problerms. I use a breaker bar and then put the end of a floorjack on and then break all my cheap sockets. lol

 

Source an air compressor, 1/2 in. drive impact gun, and 1/2 in drive 19mm socket. it comes right off. had to do that last week when timing belt cover gasket fell into timing belt

yea that things a bitch... I second everybody else who is recommending getting an impact gun. I bought one specifically for this job- I got a Rigid electric impact wrench- it cost like 175 dollars, plus 30 bucks for impact sockets, but thats the best 200 some dolars ive ever spent on tools. I highly recommend it. I got mine off in under 6 seconds, plus its works perfect for all those other hard bolts- like axle nuts, rusted exhaust bolts, etc... GET AN IMPACT WRENCH! plus they're super cool

 

1/2 drive impact gun and 19mm impact socket works wonders.

 

Thanks for all of the replies. I tried an impact gun today, but it was only set at 80psi. Bunger suggested I let it go up to 120psi, so I'm going to take his advice on that one.

 

remove a spark plug, insert about a foot of rope into the cylinder and turn the crank until the rope does not allow the crank to turn. then stick your breaker bar and socket . that should do the trick Ive done it many many times good luck
