Questions on lifting a 993 for engine removal

[David--Edwards]

Hello all,

I wanted to get your opinion on how I plan to raise my car. I have had the problem of the clutch disc not fully releasing on deceleration. 2 people have had my exact symptoms, and have found it to be corrosion on the input shaft, causing the disc to hang up at times. So, when the semester is over, I'm going to drop my engine. This is how I plan to get the rear up high enough to clear the motor; please let me know what you think. First, I'll get the front end up on those foot tall ramps that you drive on to change oil. Then I'll raise the rear from the motor high enough to where the motor will clear the bumper once out (supporting the rear with jackstands at the rear factory mounts). If that height/angle looks unsafe, then I'll remove the rear bumper (from the manual it looks like removing it will create a lot of clearance). My main concern is having the car at an angle on jackstand, since that will create some forward force. I replaced a clutch on my old '88 911, but I had access to a lift then, which made the job pretty easy. Do any of you have any comments of suggestions?

Thanks, David

Well a few observations. First I doubt you'll be able to drive the 993 onto the ramps so you do realize you'll be lifting it on there, right? I would be a little concerned about the ramps sliding. Why not use jack stands under the front lift points instead of ramps? Also, it would be best if the car was level when the drivetrain is lowered so you'll need to get it pretty high. I assume you'll be taking the engine/trans out together. If you need to lift the car while the drivetrain is on a jack how do you plan to do that? It might be nice to fashion some sort of crossmember out of some solid planks to lift the back up a bit with another jack if necessary.

The 993 is very flat underneath and deviod of good jacking locations. I think you already know this but don't lift the car on the alloy suspension components under any circumstances.
