Hey guys!
So Ive been dealing with a clutch problem so I decided to replace it. After much struggling and about 10 cans of pb blaster I was able to remove all of the bellhousing bolts and eventually the trannsmission. Now I am trying to remove the clutch/cover but when I try to break the bolts free the flywheel turns too. Any tips or insight on this? I removed the transmission through the interior. Any help is much appreciated. Thank you!

The easiest is an air wrench. If you don't have one, the next options are: lock up the engine so it won't turn-there are several options for that, turn the engine so the bolt you are removing is on the right side of the engine from where you are behind it - then use the longest bar you can use from your point of attack - there will be a point at about 3 o'clock position or maybe down closer to 6 where you can apply the most reverse torque without the engine turning the same way, even with it locked up.
Some clutch covers have holes along the sides between the bolts, some use those to insert a long tool that will hit the frame or floor, then undo your bolts.

I have a peice of angled steel that bolts to one of the engine studs, and drops down to jam in the ring gear teeth. I then flip it over when I tighten the new clutch cover.

If you have not done so, check the clutch throw-out fulcrum pin while you have the gearbox out!

If you have a cordless impact wrench or can borrow one, that would work too.

Ok. I just got an impact wrench so Im going to give that a try. Where is the fulcrum pin located and what should I be looking for?

Getting it off is only half the battle.

When you go to put it back on you will need to torque it, and the impact gun would be unreliable for that.

Here's what I did.... but it helps that I had recently changed out my flywheel ring gear and had it laying around to cut up. Really, as Tony states, anything that will secure it would be adequate.

As said, a right angled peice of steel attatched to an engine stud, will hold the FW in place.
(See graphic at top of flywheel)
But I do like the ring gear solution (if you have one handy)

The fulcrum pin is the item marked in the illustration. It is just a steel pin. It has been known to break or just fall out.

When it does, you cannot operate the clutch. A bolt is a good replacment. My cars PO just left an old screwdriver in the hole :-(

Ok. So I got the old clutch plate, etc out and refitted the new one. i also replaced the throwout bearing as advised. I am having trouble putting the transmission back in. Any tricks? It seems like the heavy bellhousing end wont line up with the shaft and splines. (not sure if I'm using the proper terms but hopefully you guys understand. How do I get the gearbox refitted? Ive made some progress and I'm so anxious to get it all back together...

Jack up the motor a little as close to the back as possible. 2x4 and any old jack that fits. You may have to twist the tranny along it's axis to clear the exhaust a little.

With the tranny out the motor droops.

Put the tranny in fourth and wiggle the drive yoke to help the teeth mesh.

I assume you aligned the clutch plate (see the blue alignment tool in the earlier pics)

Supporting the engine end plate on a section of 2x4, then sliding the bellhousing forward on the same 2x4 at least takes care of alignment in one dimension.

Measuring between the end plate and the bellhousing flange, getting the space even on all sides , also gives an idea if you are out of alignment.

Another aid is to put in some extra long bolts at the top to hang the tranny from. You can use them like a rail system to align the rest.

Agree with all, jack up the motor, long bolts, and then I used a couple large c-clamps. Get some pressure, then rotate the drive shaft flange (in 4rth as suggested).

Bolts are good, but I just used two long screwdrivers and then was able to do a bit more jiggling.

Definitely make sure you've used a clutch alignment tool though.
