Default Scorp Wins!!!

Hah! It put up a good fight, but she's all mine now!













Well, remember how we all thought it was freaky that I had a 166k mile clutch? I had no documentation on the clutch ever being replaced. Well, I was wrong. It has been. There was way too much meat left on this one, and also the pilot bushing had been replaced with a pilot bearing. As far as I know these C4s came stock with a bushing, and there most definitely is a bearing in there.

On another note, that bearing has 1/2 of it's needle bearings missing!!! :eek: That could of been the clutch noise I was hearing. I wonder if it also caused the tranny to go. The tranny, clutch, and flywheel are out of the car. I'll pull the pilot bearing out tomorrow when I feel like it. It's dark now. :)

Here is a closeup of the bearing. In green is where the needle bearings were still good, the other area the track is destroyed and there is no sign of anything. :eek:

Well this is the first one I've ever pulled. :) The bolts holding the tranny to the bellhousing were rediculously tightened, so I decided tonight to just do the whole thing at once at the recomendation of a couple buds. The 6 bellhousing bolts weren't all that tight. I'm just glad I had the car jacked up as much as I do. Otherwise it wasn't coming out :)

Hey Scorp, I agree with mackey...I never pulled a manual transmission with the bellhousing in one piece. Normally it is much easier to split them at the bellhousing. I think it would be MUCH easier to install as two pieces.

I dunno. The headers showed up today though! :D I still don't have the other tranny yet, so anything I do between then and now is bonus.

I can't believe that you had enough room to pull the whole thing far back enough to get the input shaft out of the way of the clutch and pressure plate.

I put a pilot bearing in my car instead of a bushing, and yours isn't the first one I've seen that's chewed up. Part of me wants to go back to a bushing when I pull the trans out in a couple weeks.

Now that its out, work onb those bolts...I think it would be harder to line up and "stab" during the install with the bellhousing on. How did you get the room to get the bolts and slide the shaft out enuff to clear? Have to take a bunch of accessories off the front and undo the engine mounts?

Congratulations! We all knew you'd do it! I think I'm not alone when I say that now I want to go pull a transmission :D

So let me make sure I remember, now... the transmission that is coming is the one you're putting in, right? Then you'll rebuild this one as time allows - that will be a cool project in itself.

Well, ya know, if ya got time to kill till the new transmission arrives... you might as well work on that engine.

Good luck - I'm eager for the next step :)

Mike

I could get to 5 of the 6 bellhousing bolts easily without trouble. The last one required 2 two-foot extensions off of dad's snap-on truck. I put them in OVER the tranny to the bellhousing and actually had the wrench behind the tailshaft of the tranny. With those extensions it was cake. After that I just under the clutch housing shield (4 or 5 small bolts), and rolled the jack back. I had to roll it back, let it down some, roll it back, let it down some a few times. But she came right off.

1. I get the new tranny.
2. I swap my current O/D unit onto the new 4-speed.
3. I reinstall tranny.

:)

I want to keep my current O/D unit for two reasons.

1. I know it works, I know nothing about the new one.
2. I know it is the right 0.68 ratio Z51 unit, and I don't know what the new one is.

As other above said I am surprised you pulled the trans & bellhousing at the same time. A good impact wrench would have removed the trans to bellhousing bolts. Cutting the trans cooler line was not really the best idea. You can get both lines off the OD without cutting them.

I tried every method available. Considering there is a Snap-On truck in the driveway, this means qutie a few. :) The fitting on the upper line just would NOT budge no matter what penetrator, wrench, or otherwise was applied to it.
