Need clutch fork.

It sure looks like the throwout bearing was rubbing on the pressure plate fingers.  This means it was not spinning nicely.  Over time, this would cause the fork to erode away.

Seems like a common problem eh?

Garry, I'll give you a phone call. Maybe we can work something out.  

Just got back from working on the car all day at Clynt's place. Need to eat first before making any calls or reporting any progress.

 

Note the area around the CV shaft hole, your's look like spider web bracing lines.   This is my old 4spd, it has a smooth casing around the CV shaft hole.  Mine was 84 trans that I had in the nitrous V6, notice the huge crack that follows the base.  Under load that crack opened up to nearly a 1/2 inch wide dropping all the fluid onto the ground in a matter of seconds.

The more I think about it, the more I think I should get an engine hoist and drop the cradle on my parts car. It'll be an ugly job as the car is out in the open (in all the rain ) in a corner of my backyard, but at least I wouldn't have to worry about putting the parts car all back together again afterwards.

I can just transfer the entire clutch/transmission assembly over from one car to the other. Would've been a lot better to have been doing this in July though.

I just hope Clynt's a patient guy and doesn't mind my disassembled Fiero up at his place "hanging" around for another week or so.

Yeah, I'd consider it if this Fiero was an '87 GT with a Getrag 5-speed.  

So Dave, recognize anything in this picture?

I can't believe where the time's gone since I last posted in this thread.

Clynt's been very patient with me the last couple of months as I've been s-l-o-w-l-y working on the car in the under-cover area in his backyard. It's great having something to keep the rain off. It was a little cool though a few weeks ago!

The 5-spd tranny is in as well as the 5-spd shifter and cables. Bent clutch pedal was replaced, as were the clutch master and slave cylinders. 

Rear brakes calipers and hoses also had to be replaced, as did the master brake cylinder and combination valve.

The timing cover was also removed to bang out a dent that was rubbing lightly on the timing gear (but rubbing hard enough to create quite a whine).

The image above is a "hybrid" exhaust system made up from the original downpipe from the '84 duke mated to the muffler and twin tail pipes originally from Dave's old '85 GT. Thanks to Clynt for welding it up for me.  I wanted to put dual-exhaust on this '84 as the rear bumper had been replaced by the previous owner with one from a GT (twin exhaust cut-outs). It looked very odd with the stock single exhaust.

In kind of an oddball repair (as I don't recall reading much about anyone else trying this), Clynt also helped me rebuild the duke's dogbone. One of the two rubber bushings was shot, but the other was fine. I had a second dogbone in the same condition. Using a homemade tool that Clynt had originally created to remove cradle bushings, we swapped over a good bushing from one dogbone to the other (replacing the previously removed worn out bushing). A little heat from a torch aided in the process. Worked out very well.

So tomorrow's the big day... starting it up for the first time since all this began. Hopefully no oil or water leaks, etc.

 

Woohoo.... success!

I finally got everything necessary back together to take a test drive and I had a fun time tearing around Clynt's neighborhood. The little '84 felt great. The 5-spd tranny/clutch/shifter are real smooth. I couldn't get too crazy as the car still has no nose or rear bumper or plates on it , but I drove it enough to get a sense of how everything worked.

And the dual-exhaust on the 4-banger sounds pretty good!

Although I've had this car for more than five years, this is the first time I've EVER driven it. (It was undriveable and therefore towed to my place when I bought it all those years ago.) I'm quite pleased.

 

If anyone has this problem again (Like I did), I found I could reinforce the clutch fork by welding in triangular shaped pieces between the horizontal and vertical pieces of the fork...in my case it was the horizontal to vertical joint which failed (This is the stressed area).

Chay

I got the '84 home today. Still lots of little things to do to it, but at least it now runs and drives just fine.

Special thanks to Clynt for the use of his hoist and a covered work area for the last couple of months!
