Default Help!! Engine forward Clutch Swap -Remove fork release pin??

Help!!

I am right in the middle of replacing my clutch (02 WRX) using the engine forward method. I have the engine and tranny separated about 3/4" at the top but can't move it any further. I can wiggle the motor up and down and side to side but it won't come forward any more. Should I have removed the Clutch Fork Relaese Pin before trying to split them?

I folowed the method described here: http://wac.addr.com/auto/obs/clutch/clutch2.html

It says nothing about removing the Fork Relaese Pin.

I've been struggling with it for the last 2 hours. It might just need some more leverage to separate them but I don't want to damage anything.

If I do remove the fork release pin, do I have to remove the slave cylinder first?

it's a pull type clutch. it is probably getting stuck on the throwout bearing / fork. You need to pull the fork release pin and pull the fork up and out of the throwout bearing. Thus freeing the throwout bearing and PP and then they will be two halves. BTW to pull the release pin you use the battery tie down (OEM)

BTW that FAQ is for a push type clutch. It doesn't need need to have the clutch fork removed to separate the tranny from the engine.

and when installing the new clutch. while the tranny is out. install / lub up the throwout bearing and install into the tranny with the clutch fork and install the release pin. Then when the tranny is back into the car push the fork toward the firewall until it clicks.

one of inner front timing cover bolts also works very well for removing the shaft. it you use one that has the 3/4" or so shoulder then it sticks out the hole just enough to get a pry bar on shaft to remove it

Thanks guys, got it split after removing the pin. All I need now is to figure out how to get the pilot bearing out of the flywheel, without removing the flywheel (if that's possible)

is one way to do it. But I'd just take the thing off and tap it out from the other side.

I just took a better look at the flywheel and it's needing skimmed. There are spots all over it. I'll knock out the pilot from behind like you said.

What are the chances of finding somewhere to skim it on a Sunday... Somewhere between none and feck all I'd guess?

you just need to find a machine shop that can resurface the flywheel that works on sunday.

and if you want the machine shop will have to remove the pilot bearing. I requested to them to not reinstall the pilot bearing as I had another one. So they packaged them in together and I installed the pilot bearing myself. (you can also get them to install the new pilot bearing.) if you find the right shop it won't cost you anymore.

I've done a few clutch swaps before but this is my first Subaru and I've never seen a flywheel come off looking like this. It has several hot spots, but the metal around them appears 'wrinkled' .. best way I can describe it!

The clutch has been 'chattering or 'juddering' for a while now and was steadilly getting worse.. until it started to slip. I can see now what was causing it. Do you think these flywheels are made of poor quality steel?

I have a picture or two but can't figure out how to add them to this post
