911 engine removal help

mikey911 · 08-13-2005, 12:40 PM

I am attempting to remove a 1983 911 sc engine. I have completed and double checked all of the steps in Waynes's book, b ut I cannot disengage the motor from the transmission. The engine will come out about a 1/2 inch and will not come out any further. I have the bumper off and have plenty of clearance.

'what am doing wrong...any help or suggestions would be greatly appreciated.

Thanks

Must be the clutch / flywheel / throwout bearing binding in some way. I always take the transaxle & engine out together, and usually have some trouble seperating the two on the shop floor anyway...

As I recall, there are some bolts on the clutch assy used to force disengagement, three of them & you need to turn the crank to access all three???

Have you taken the small clutch arm off? It won't split if you don't. Ask me how I know...

yea took the clutch arm off, I was looking at that and did not understand how having that off made a difference, maybe I did something wrong there

The cable pulls on the large arm, the large arm then pushes on the small arm. The small arm turns (via splines) the shaft going up into bell housing.
Taking the small arm off allows the shaft it was mounted on to turn as you pull angine away from gearbox. It (the shaft) could be binding on the larger clutch arm. Try pulling with a bit more oomph and watch what the shaft/arm does.( You should not need to remove the large arm)

Did you disconnect the wires coming from the engine wiring harness going to the starter/reverse switch on the tranny?

This is excactly why I like to see the engine come out with the tranny the first couple times someone does this. It reallly helps to have a good mental picture of what everything looks like and how it all fits together, especially when reinstalling the motor. I know I will get some flames for this, but there is a reason the Factory, Bentley, and (heaven forbid) the Haynes all describe taking the motor out with the tranny as a single unit.
Just my .02 though...

I vote drop the tranny with the engine. 5 mins with an impact wrench and the CV bolts will be undone. I find it much easier to reinstall the engine and tranny as a unit as lining them up can be a real PITA.

I can't imagine trying to put the engine back in with the tranny up in the car. I have a hard enough time mating the two with them sitting on the floor.

me neither. I can't imagine tring to get everything to line up under the car...

Wow, I expected to get flamed! Glad some of you agree with me. I really think that is one project in Waynes fine book that leads people astray....... It really should detail how to do it with the tranny still connected. However, I think JW leaves the tranny in.......

Yes it's much better to remove both.
But I still forgot that pesky arm

I've used both techniques for engine removal and they both have merit. I find seperating the engine and tranny easier with the tranny left in the car. Gravity is your friend.

It is much easier to take the engine out without the transaxle, but it is much harder to put it back in that way

I've done it twice, once you get the tricks figured out it is a piece of cake. Just make sure the engine is on the same plane as the transaxle, and by all means PULL THE STARTER OUT!
That makes it so much easier. You can look in that big hole and see the throwout bearing and arm and line them up just right, then all it takes is a good wiggle and a push.
