Alright . I cannot remove the fan to fit my socket on the 928 s4 engine. I removed the spark plugs to make it easier to rotate. Is their any other way to rotate it right so I can align the torque convertor drain plug into the window? Thanks

From underneath pry the starter ring gear with a flat headed screwdriver. Quick and easy even with sparkplugs in. With plugs out, gloves on, actually easy to rotate ring gear by hand.

MainePorsche

Nope.
Sounds like your using an extension on your socket. Even a short extension will not clear the fan shroud.
I use a deep socket with no extension directly to my ratchet. Never had an issue. I bought the deep 27mm socket just for the crank rotation.

Standard 1/2" drive Craftsman ratchet with a 3" extension and a regular 27 mm socket will fit on the crank bolt with the fan shroud in place, and rotate the motor form below while you're lying on your back under the jacked up car.

No need to remove the fan(s) as already stated. You must not have the right tool. Again, as already stated, you need a 27mm deep. Ideally, you would have a helper turn the engine over by hand until the TC drain plug were accessible to you at the rear. Without a helper or the right tool, I would suggest to do as Landseer suggested. Less effort to check the TC drain plug as you turn the engine over this way.

I ended up rushing to auto zone and bought a 3 inch extension. I finally rotated the engine to see the drain plug. I semi stripped the drain plug but I got it off. I was surprised how much fluid came out of it. I am going to see if the Porsche dealership sells drain plugs.

The drain plugs are different between the pan and the converter, although the thraeds are the same. You'll want new sealing washers for both plugs. The converter and the oil sump are both Mercedes parts, so if no joy at the Porsche store and you don't care to wait for a care package from one of our suppliers, try the local M-B parts department. I'm not sure the plug is a 'consumable' part, but the sealing washers certainly are.

Be sure to ues the correct torque on the drain plugs, and for sure on the bolts that hold the sump to the bottom of the transmission. The sump bolts have incredibly low torque requirement, and will warp the sump if overdone. The inch/lb 1/4" drive torque wrench is my weapon of choice, since the requirement is so far down in the range of the 3/8" torque wrench.

To confirm what Dr. Bob said, I got my sealing rings from the local M-B dealer. M-B does not list them by size, just part number, so take your old rings with you to match the size. They were a bit pricey.

Thanks for the replies. I got pissed off at trying to move the engine with a screw driver. I risked loosing my parking spot and drove my daily driver to autozone before they closed. I purchased a 3" extension and it worked great. I almost stripped out the drain plug. Then I used a socket hex key instead of the allen wrench. It took alot of power but got it off. I have a new one on order. I was going to use a porsche dealership but they said it would take three weeks to come in. I also purchased a differential cover gasket.

See page 1.6/1 for torque values you'll need.

I went ahead and hot the drain plug, washer, and the new version modulator from the MB Dealer. I was very surprised they had it in stock.

How did you guys take of the reservoir?is theit a clip in top?

MainePorsche

Try again.
Not sure precisely what you're asking.

1989porsche928

The fill reservior. Do I just pull the rubber very hard or is their a clip

MainePorsche

If you're going to fill through the reservoir you will UNSCREW the red cap (37). Be sure to keep everything clean. NOTHING CAN GET INTO THE TRANS FLUID. I use the kind of pump pictured here attached to a 5 gallon bucket. The U shape makes it easy. I didn't have a pump with enough pressure to allow me to fill through the Filling Port.

Add: Note that after you remove the cap there is a screen recessed in the opening. I take mine out to fill otherwise it would take forever and make a mess.
