Crank Pulley Removal

[cammmy]

Hi Guys

 

Having a crack at the timing belt this weekend but nothing has been going right for me.

 

I've loosened the triple-v pulley and was checking out how hard it will be to get off. Definitely can't do it by hand, persuasion with a mallet is doing nothing, pry bars won't budge it and If I put my puller in there, I can't get a spanner on it.

 

How do people get it off?

 

After reading the various topics I was reasonably confident going into this (having done timing belts before) but I'm really struggling with this one. Everything seems impossible to get to and remove and everything looks like it has to come off before everything else.

Mine was a really loose fit,with just corrosion holding it fast. You could try lots of penetrating fluid and use a v belt pulley tool to rock it back and forwards?

[cammmy]

Thanks, not heard of one of those mate. Do you have a link?

 

I was going to try penetrating fluid but have misplaced the syringe I use for it

It's like an oil filter wrench but uses a v belt rather than a plain strap or chain... not got a link but I'll see if I can find one.

Hopefully cheaper alternatives is you do some research.

I would definitely get some proper penetrating fluid in there (not WD-40!), and be patient. I use Aero-Kroil, but everyone has their magic favorite. Acetone mixed with ATF supposedly works well.

If it's the crankshaft pulley you're referring to, I wish you all the best. Mine was an absolute pig.

Yep, penetrating fluid, and a gentle rocking motion alternating sides with a rubber or plastic mallet or the rubber strap wrench mentioned above.  It has a woodruff key, so you need to rock it on that.  The pulley is aluminum and will expand faster with heat, compared to the crank.

Sometimes you just have to hammer the crap out of them.

I could help with that

Use a length of wood against the pulley and give that a whack - should then give fairly easily and you wont damage anything

I can back up Sparky's earlier claim. No amount of harsh language seemed to move the thing, you just need to keep twatting it.

[glynherron]

But remember it's only soft aluminium...

[sanj]

I stand by my suggestion.

[cammmy]

Cool, cheers guys.

 

I have plusgas, just need a syringe as I can't get the tin in there. Also have a crème brulee torch thing that will hopefully help.

 

Will then apply different styles of violence.

I always find in situations like this,  care and temperance with gentle persuasion usually

gets the desired results........

 

Failing that treat it like the ex wife............ give it everything you've got.... and then some..

 

Unfortunately the later is usually followed by tears...........oh..so many tears.... 

[cammmy]

I've ordered various tools to try and make the whole job easier. For the crank pulley, I'll use plusgas, heat, gentle persuasion and an old belt with some molegrips as a makeshift pulley tool.

Be prepared for a long job. Maybe a mattress under the car will help, at least you'll be able to have a rest between beatings.

[cammmy]

Yeah, I've got a 4 way extension lead for the work light. I'll bring the kettle out too
