Ok, so. Total newb. at this...
Car on jackstands, engine and tranny installed. CV joints hooked up, car in second gear, spin rear wheel by hand and engine does not turn/move. Rear wheels spin with starter and car in gear, but not when engine is running, idling. Somethings wrong, right? What'd I do? |

Make sure that one of the wheels is stationary.
Only lift 1 (one) wheel... |

Might you have adjusted the clutch cable too tight & It's not allowing the clutch to engage fully? It might be barely touching and that's why the wheels spin with the starter only.
I adjusted my first clutch too tight & it slipped big time... like, nothing moved (IMG:style_emoticons/default/dry.gif) ....b |

Allan - I think you're saying that one rear wheel needs to be on the ground if I want to turn the engine by the other rear wheel, correct?
I had the car in gear at idle. I haven't even gotten to adjusting the clutch cable at all, it's just hooked up. I don't know if it's too tight or too loose or how to tell, since the car hasn't been driven yet and car is on jackstands. What about with the clutch cable completely unattached at the tranny, does that mean the clutch will be engaged or disengaged? |

Forget the flywheel??? tranny not totally seated? Clutch backwards? (don't know if that can happen but just a thought)! Oil got on clutch & flywheel. I did that (IMG:style_emoticons/default/headbang.gif)

It's simply just mating the engine and tranny together right? And the starter turns the engine over. The engine came with the clutch and flywheel etc. already on there, I just bolted my tranny up to it... Looks like I'll have to drop things again... |

How much free play is the throw out arm supposed to have? Mine moves fairly easily by hand. It can touch the transmission case on the engine side, is that normal? Also has some free play up and down. Could a missing throw out arm bushing be my problem?

i bet your clutch plate is backwards, the little nub part that has the splines goes toward the PP, not the flywheel. If you have it backwards it offsets everything.

Thanks Britt. And thanks for all the responses.
I guess the only way to know is to drop it and take a look. I'm sure this has been asked a million times; Can the tranny be dropped seperate of the engine? Am I going to have to remove the exhaust??? (IMG:style_emoticons/default/sad.gif) |

(IMG:style_emoticons/default/sad.gif) yes, you can drop the trans w/o dropping the engine. make sure you support the engine. if the exhaust is of stock style, you do not have to remove the exhaust, muffler probably, not heat exchangers. |

Hammy,
I am keeping it simple because that usually works. You said you are a newb. I read where the clutch was already on the engine and you bolted up the trans ,right. Didn't see anywhere where you mention the throughout bearing OR the pressure plate. If these ( one or both ) were missing , I'm betting you would get the exact same symptoms you are getting. If you don't have a Haynes to see what the engine should look like with the pressure plate installed , go to Pelican web site. Lots of instructional pictures there. Good luck, Tom |

If you have it backwards it offsets everything. If the friction disk is installed bassakwards, the clutch will not disengage as the throwout bearing cannot depress the fingers on the pressure plate. Rear wheels (if both off the ground) will spin even if transmission is in neutral due to internal friction (pilot bearing, main shaft spinning .....) If you can't turn engine with one wheel jacked up and car in gear .. 1.) You're not in gear. 2.) The friction plate (driven plate) is missing 3.) The center drive spline has broken out of the friction plate 4.) The throwout bearing is somehow depressing the fingers on the pressure plate causing it to be in the "released" position as you bolted up the tranny. 5.) All the clamping springs in the pressure plate are broken 6.) The pressure plate is missing |

Thanks for all the replies.
Ok, this is weird. I checked the other rear wheel (driver's) and it spins with the car in gear... Other side doesn't... |

That's completely normal. It simply means your brakes are dragging a little more on that side. Usually only one side will turn, because once one side starts turning it's eaiser to keep it turning that it is to get the other one to start. (due to inertia, static friction being greater than dynamic, etc) There's a really nifty exhibit at the exploratorium if you want to see it work in action.
