Stubborn crankshaft pulley bolt

[goldNSX]

This guy uses a simple method to break the bolt free: watch from 0:20 on: http://www.youtube.com/watch?v=2Zu5g95gpqo

good or bad?

I just want to hear your opinion.

Wouldn't do it. I don't know what the torque on the starter motor is, but I'm sure it's way over 200 ft. lbs. I'd be afraid the socket would jack/twist somehow on the nut and get stuck. Looks easy though .

i bought the pulley holder a few months ago, and used a breaker bar, easy as pie... i didn't even need to put any strength into it

very common way to remove bolt by expierenced mechanics , have I done it before-- yes but I know what to expect . Just get a good 3/4 impact and wing it out . The problem with the Honda crank bolt is that alot of impact torque is absorbed by the crank . I have a 3/4 gun that will remove any crank bolt. some of the newer 1/2 guns are capable

if he had a gun, he wouldn't be making this post.

Using this method is not without risk, especially when you put extensions on the socket.

The weight of the long breaker bar and the extension can cause the socket to tilt at an angle. It helps to use a jack stand to help support and to assure that the socket is seated straight and secure.

Make sure keep everyone from standing near that area because it can be very dangerous. I've seen a socket come shooting out, almost hitting someone standing nearby.

What about the crankshaft and it's bearings?

I made the tool to hold the pulley then used a braker bar with a 4' pole slid over it. It's a tough one.

You hit lotto that day , these bolts dont come out easy as pie , somebody was in there before you and did not torque it properly . Read Larry Bs reply ,it says it all

The manual on my 97 clearly states do not use an impact to install ,for removal they do not specify (another words a impact is ok ) . You will not damage the crank or bearings

Yes, I know that in impact is ok to remove the bolt. My worry is about using the starter to remove it as all the torque goes along the crankshaft and it's bearings.

I never seen any shaft or bearing damage as a result of using the starter.

+1 on the 3/4 impact

 

[goldNSX]

I never seen any shaft or bearing damage as a result of using the starter.

How much cars did you see where it has been used? :wink:

 

[ralph cerbone]

OK look i not a big fan of doing it this way , but in 40 yrs of working as a mechanic /tech/instructor i have never seen a crank or bearing problem ,I hope this answers your question

This.
