Crankshaft Pulley Bolt

I'm having difficulty removing crankshaft pulley bolt using impact wrench on
my '96 Elantra. Any chance this bolt could be left hand thread? I have the
impact wrench set to remove the bolt counter-clockwise.

Thanks,

Well if this helps any...

On my 99 Sonata (v6...not that it matters) I tried the same thing, with
the impact wrench- didn't work. I ended up trying to hold the engine from
turning while I used a breaker bar by putting something through the cam
sprocket to help the old timing belt to help stop the turning- big
mistake. DON'T do it by putting something in the cam like I did- it
broke.

Anyway, on to your problem... I ended up using a breaker bar and a piece
of wood and a large screw driver to jam against the pully and the end in
the wheelwell (to stop it from turning) and then cranked the bolt off. By
the way, mine was standard thread out (lefty loosy, righty tighty)... so
counter clockwise out.

It was as if the bolt was coroded to the pully (may be that's just our
weather in WI though)

Good luck.

 

It's a right-hand thread. Make sure your impact wrench delivers at
least 200 ft/lbs. Some of the cheaper 1/2" electric models just aren't
strong enough. And a lot of torque is lost because the crankshaft is
free to turn.

Try alternating between tightening and loosening the bolt, 10 seconds
at a time, in order to break the threads free. It can take up to five
minutes before the bolt comes loose. Allow the impact socket to
cool down if it gets too hot.

In some of the toughest cases, I've had to remove the torque converter
cover and put something in the teeth of the flywheel to prevent it from
turning.

On some cars, it's also possible to attach a breaker bar to the bolt and
use the starter to break the bolt loose. Figure out which way the engine
turns, install the breaker bar and rest against something it won't be
able
to break, and turn the key momentarily to start and back off. Make sure
you don't allow the engine to start and run for any length of time. Bad
things could happen.
