Step 21 - Secure Jack Under Engine

There are a number of different types of jacks that can be used here.

Tranny jack (Not Shown) with a special carrier. You can fabricate the carrier from plans in the factory shop manual or purchase one from a place like Pelican Parts.

Table & Tranny Jack. We used a jack up table (from Northern Tools) with a wooden jig and a tranny jack (also from Northern Tool).

Place the jack or table under the engine/transmission assembly and apply pressure.

You will need to lower the engine first to allow about a 15 degrees tilt with the transmission pointing up. This will allow you to remove the trasmission shift rod from the body tunnel.

Step 29 - Mount Engine on Stand

Use a 911 specific engine mount. They can be ordered from specialty tool companies like Sir Tools or Baum Tools. You need the yoke and the clamp.

The yoke and clamp were attached to a modified 1250 lb engine stand (Northern Tool). The engine stand was used because it's wide legs allowed us to use the jack up table to slide the stand (with clamp) on to the engine (with mount).

Note the longer stud on top and shorter stud on bottom. You can purchase special "bolt shafts" that are the right length to secure the mount to the engine, but we just used really big nuts.

Be sure to secure yoke on oil cooler side of engine.
