I just dropped the engine/tranny in my 73. There is no point in not taking the tranny out with the motor its only an extra ten minutes and putting it back in was much easier I suspect. Remember the Gear shift lever and parts dont get touched!! I was shocked, you take one small allen out and the shifter is seperate from the tranny!!
A couple of lessons I learned that were not in the manuals.
1.) dont forget to take the speedometer loose from the tranny - its hard to see behind the mount.
2.) make sure to use indelible marker on the tape for marking the wires : - ))
3.) When fitting the motor back up dont sweat the alignment of the bolts, particularly the tranny bolts, get it up close to position and start the bolts a little. Once the rear bolts are in every thing else lines up pretty easily. I tried to start with the tranny bolts but because the back of the car is up in the air so high the angle wont let you start the bolts. I spent way too much time messing with it.
4.) Leave all of the 4 main bolts loose until almost last. You will almost certainly leave something hanging down and pinched between the tin and the chassis.
5.) If you have the right jack and a helper at the end, you will have the motor out in 1 hour!!! Its really a snap. Especially as handy as you must be to have done the other things you mentioned.
6.) Be prepared to spend a good bit of time cleaning the engine compartment and parts, follow Waynes advice and replace the seals he recomends. You will probably realize that they were all leaking even if your car doesnt drip.
7.) Get several rolls of paper shop towels other wise you will quickly use up the cloth shop rags and have to throw them out (If your wife is like mine : - ))
8.) The front and rear main seals are incredibly easy to get out. Porsche actually provides a slot (on my SC anyway) to get your screw driver in and pry them out.
9.) Dont forget - new fly wheel bolts.
10.) Buy one of Waynes Flywheel bolt tools or get a cheap after market. If you get a cheap after market cut it down!!! The cheapy I got was too long and wobbled when trying to re - torque to 106 ft-lbs I stripped it and had to cut the tool end and the other end - huge pain, trust me cut it down.
11.) Since you have to take the flywheel off; the Porsche engine stand is really convenient because you can do it with the engine on the stand. They are awfully expensive. Fortunately, I was able to borrow.
12. the throw out arm and the way the clutch woks will freak you out!!! Look at it carefully so you understand it before you take it apart. Its simple but its different. Pull the starter off and look in the holes at how it works after it is on the ground.
Finally
13. If you can, do the work where you can roll the body out after the engine is out and degrease the engine/tranny compartment - I cant believe how much crud is in there.
Good luck - you wont believe how easy it is.!!!
