Crank Pulley

[Miguel Estrella]

Hello Everyone,

I’m currently changing the Timing Belt on my 2005 Acura Tl. I’ve come upon a snag that hopefully someone can help answer. I’m currently having issues removing the Crank Pulley after removing the Crank Pulley Bolt. For some reason the pulley will not budge or move at all. Has anyone else experienced this issue and or have any recommendations on how to remove it?

Thanks

Bolt threaded most of the way back in, 3 jaw puller?

That’s what I was thinking. I was just concerned that this could damage the pulley since it seems it could only grab the flanges.

Hmm, well, it would be best if you don’t damage the pulley, yes.

Do you have a picture?

I was just looking around on the interwebs and it seems you have an odd problem.

The only thing i have found that gives everyone a fight is the bolt and there is no reference to the pulley not coming off at all.

Sometimes they get junk or rust buildup inside between the pulley and the crank snout and make it difficult to remove by hand. If you can find a way to put a puller on it I think you will find it wont take much effort to get it off.

I can add a picture but there is nothing that really indicates what the issue could be. It looks like every image on the internet in regards to an Acura TL Crank Pulley.

You’re right there is nothing in regards to the crank pulley being the issue which is why this is perplexing and frustrating. I was hoping Ericthecarguy may have dealt with this issue before and could provide some tips on how to remove.

I will try the puller tomorrow and see if that’ll work. Hopefully it will otherwise I’m up s**t creek.

It can get rusty back there. Have you tried some penatrating oil?

[Miguel Estrella]

I did yesterday. I applied some to the front but that didn’t work. So I applied some today to the backside of the pulley. It just will not move! Highly frustrated!!!

I think you will have to use a three jaw puller even if it damages it.

Sometimes we all have to wreck a perfectly good part to get the job done.

Try using a torch to heat it up and loosen it.

You can try this method.

You will need four tapered hardwood wedges, two large C clamps, and a soft-faced mallet.

Cut four tapered hardwood wedges. Oak, maple, or ash are good candidates. The taper angle on all pieces should be the same or very close.

Feed a pair of wedges, narrow ends facing each other, behind the pulley, so that the tapers overlap, and push them towards each other until they are tight and will stay in place.

Do the same with the second pair of wedges, locating them on the opposite side of the crank stub, and parallel to the first pair.

Put a large C clamp across each pair of wedges, on their butt ends, so that tightening each clamp will squeeze each pair of wedges tighter together.

A bit at a time, tighten each clamp equally, and give the pulley a few sharp smacks with the mallet after each tightening. Eventually, the pulley should “pop” loose.

This technique can be a bit fiddly, or even impossible, especially where space is limited. Another thing to watch for is that the pressure exerted by the wedges doesn’t damage your plastic timing belt cover.

I might try an air hammer with hammer bit to try to shock it loose..
