Is there a special tool or method for getting the crank sprocket off the crank spindle? Seems stuck solid.

Cheers,

Andy

 

any tips?

 

help!!

 

I had my garage take mine off when they did the rebuild.

2 days later I needed a new one cos it had cracked when taking it off.

He said it was a bugg£r.

Good luck

Dizzy - and here's me thinking this was a technical forum!
To be honest, you're probably right! Seems a shame to admit defeat just because something's stuck on that might just require a) gentle pursuasion (brute force!) or b) a special tool to remove.

I've never done this myself but I've heard it's possible to do it with a breaker bar and turning the engine over (crank sensor unplugged of course).

Perhaps someone else has tried this?

Andrew...

 

Soak the offending bolt in spray oil. Leave it for a day, then have another go. It is surprising just how much this helps.

I've taken crank bolts out before now by putting the car in a high gear and getting an assistant to push the brakes (hard). Then levering with a long bar or using an impact wrench.

Another way is to lock the ring gear on the flywheel with something. (I used a broken starter motor gear and a 6 foot bar on a Montego once)

Neither of these have been tried on my Scoob!!!

AndrewC's way would worry me a bit, as I don't like getting too close to big bits of whirling metal!

I think the idea is to anchor the breaker bar against the chassis somehow, not holding on to it.

I said I've never tried it.

Andrew...

PS. I've just had this vision of someone flying across the garage holding onto a 3 foot long bar whilst someone else turns the starter key

 

have you not finished that yet m8

i assume you have got the aircon/alternator pulley off. for the crank sprocket you need a flywheel puller. you can hire them from the hire shop. job done.

stu.

 

Thanks for the info guys, but I've already got the crank pulley off (actually it almost fell off! ).

Stu,

No, not had time yet - bit chocker with work and other stuff at the moment. Luckily got another car to use but must get Scoob back on road soon! Thanks for the info, I was pondering how to make a tool to extract the offending pulley, but a flywheel puller sounds just the job. Do you think HSS or toolmart would have one?

Will keep you posted,

Cheers,

Andy

 

andy,

im confused now. the aircon/powersterring crankshaft pulley comes off first, then the plastic cover and then the crank sprocket.

you need a special tool to stop the crank turning when you loosen the 22mm bolt to take the crank pulley off and then a puller (maybe) to get the crank sprocket off.

 

use a couple of pry bars but make sure you do not break the crank sensor pick-up lugs off.I am guessing the timing belt is off,as is the crank bolt and pulley,the toothed sprocket will just be rusted onto the shaft.

I take it you are doing the oil seal?

 

T-UK - no not doing seal, but trying to get other half of mangled/snapped woodruf key out so I can replace it and then but the crank pulley back on.

Stu/Kipax - I'm a bit confused too with all the advice on how to get the crank pulley off. I have actually got the crank pulley off and I just need to budge the crank sprocket to extract the old snapped woodruf. I'm gonna take you advice and try to get an extractor tool for this.

Everyone else - Thanks for the info anyway. (It's a bit like a bus - wait ages for some advice and shed loads come along including stuff you don't need )

 

... a couple of pry bars works to start ... then I used a three leg puller ... but bent some steel to shape instead of the normal legs so that it would grip in the small gap behind the sprocket .. i did break the lugs .. but the sprocket is about 20 quid + vat from Subaru .... b*st>rd of a job ... do the oil seal while you are there! good luck

 

Did my cambelt a couple of months ago on a 94 WRX easy peasie... Uses a U bolt in the two holes and a bar through the loop and had my son (14) hold the bar (it was a 18in cold chisel) whilst I applied the ignorance to the bolt.. No problemo The whole job took about 5 hours including rad removal and flushing etc...
