Hi

My first post, ive been reading for a while. I've owned and worked on lots of aircooled 911's but a 997 Turbo is a new toy, and completely new territory.

Its a 2007 997 Turbo (3.6)

I need to replace the dual/tandem pump on the left side of the engine. I would really like to read a procedure in a workshop manual first, but i can't find one. I have allready bought a few manuals from ebay, advertising that they cover the turbo, but they don't actuall seem too.

So two questions :

A) Workshop Manual (with tandem pump procedure)

I'm more than happy to pay for a workshop manual (i.e pdf/link) which covers the turbo models and specifically with a procedure for the dual tandem pump replacement

B) Alternatively - anyone suggest a "procedure"

Do I need to remove the exhaust? Can i do it all from below? I can only see two torx bolts on the bottom, and looking at the PET can see two more above, but can only just feel them.

How do i remove the vac line connection? Will i need a new vac line,etc.

Basically anything you can tell me and im all ears!!

Are you replacing it because of corrosion? You can now get this cover as a stand alone item from 9meister:

Hi No in my case, the pump is worn out.

I would really like a workshop manual, i always prefer to read up on a procedure before i do it. Any idea where i can get one, the usual ebay links have not been fruitfull so far

So i have found that alldatadiy.com has a manual for the 997 turbo, the procedure for the tandem pump removal is under oil pumps. I know understand the vacuum connection unbolts. I'm posting this info for anyone else that needs to know. I have subscribed and confirm that it does cover the model, which is good news, i hate working blind!

I still have the questions of what else i need to remove to get the tandem pump it, i.e exhaust, parts above it, drain oil, etc? This isn't covered in the manual.

I guess im just going to suck it an see!

This is everything you need to know

Thanks for the procedure. That was really cool! =)

If anyone else needs to know, you can remove the tandem pump without removing or draining the cooling system pipes, and the exhaust/rear engine mount bar. Its a bit tight, but you can get to all of the bolts.

o7silverturbo

no problem anytime

yeah the bad news is yes you do end up stripping down the back end of the car! shame the pump has actually gone as alternativecarparts actually make a replacement tandem pump cover for the turbo complete with new rubber washers which Porsche do not sell without a new pump...

Turboslut

anyone have the part number for this pump?

Anyone know where @o7silverturbo got the instructions? I too am struggling to find a manual that covers the Turbo.
