Compare dropping a VW to a 911 how much different?
 

I've dropped, changed clutch, and installed new engines in a Type I VW (fiberglass replicar), but never a 911.

1. What are the signifigance is the differences? and

2. How wary of the weight difference should I be?

Thanks

i have done 10 ish 914's and a million vws, but never a 911. consesus of the board indicates dropping the tran and motor together is easier. the clutch release gets hung on the throw out bearing. i smell wayne selling one more book here.

when you do the clutch. ALL parts should be replaced and the fork given a serious cleaning and inspection. if you resurface the flywheel or get into the rear main seal, the stretch bolts need replacing also. do it right. do it once.

The Porsche eng. & trans come out as a unit, then you seperate them. Rotate the t/o bearing arm as you pull the trans off the motor. The t/o bearing is attached to the pres. plate vs. the arm on the v.w. trans. Make sure the t/o bearing arm engages the t/o bearing when connecting the trans back up. The 911 is probably 250 lbs. heavier the the type I eng.& trans. The ring gear comes off the pressure plate and goes on the new one.

Add about 200 lbs. The difference is you will have to remove the trans with the motor. Instead of the four bolts that hold the motor to the trans, you remove the 4 bolts that secure the trams and motor mounts. You also have to disconnect the shift cooupler (mark it first), and disconnect the cv's at the trans. Everthing else is relatively the same. I had plenty of expereince in dropping VW motors and my first motor/trans drop in a 911 took about 3.5 hours. Granted, i used to drop my VW motor in about 20 minutes.

Thanks all. The 200lbs difference is something I needed to know, along with the peripheral repairs if needed. Project no. 7 in 101 Projects seems to indicate the engine only can be removed, am I wrong here? This is a 1969 911. Thanks

only the 70-71s had the t/o bearing that had to be turned to release it from the fork. a 69 pulls right off the trans, which can be left in the car. just disconnect the shift coupler in the tunnel, and lower the engine just enough so that the top of the fan housing clears the rear "frame". then it's pulled back, off the trans, and lowered more, to clear the rear valance. pretty much like a VW, but more crap to disconnect, and the oil needs to be drained from the tank and engine.

Its a piece of cake. The second time you do it it will be 2 hours, the first time 4. If you are handy enough to do the VW the Porsche wont be a problem. I think it was harder to get the I4 out of My Datsun 510.

Thanks John and EW. If or when the time comes, the plan is to order the clutch and any seals that can be replaced in the process, from Pelican.

I've taken just the engine out (without the transmission) a bunch of times.

Never had a problem doing it that way.

Taken it out as a unit, too, which is fine, too.

The weight does make it a little unwieldy. Esp. if you are trying to do it by yourself, with nothing but a floor jack! :eek: Makes for a fun balancing act.

if your replace the clutch do you have to use some type of guide pin to to line it up before attaching it to the transmission.

gary

For clarity..
I believe the VW engines are about 250-280 lbs...the typical Porsche engine is 400-450 lbs...to which you ADD about 130 lbs for the trans...right? So be careful about thinking the all-up weight difference is 200 lbs . You're taking out a motor/trans combo on a 911.
