To quote the FAQ:

"Turbo to Manifold Nuts. [Query] My turbo to manifold nuts are loose. Is there a gasket in there? How do I tighten them? [Response: Bob] There is no gasket between the turbo and the manifold ... The Volvo tool for these nuts is an open end wrench about 6" long with a square drive hole on the other end for a torque wrench which is held at 90 degrees to the wrench"

Does anyone have the Volvo pert number for this special tool?

Thanks,
Chris

Your 940 does not need this tool since the nuts retaining the turbo to the exhaust manifld are on the front side of the exhaust manifold and turbo assembly. A combination wrench should do the job.

I got a couple of service manuals. I feel even more dangerous now. Per TP 31003/1, Turbo charger to manifold bolts, must not be longer than 89mm (3.5"). No mention of a special tool in my book. No seal or gasket between the manifold and the turbo charger. It looks like a stepped flange fitting. There is a locking plate, two, two piece sets, that prevent the bolts from turning after asm. Lube the threads and the locking plates with paste 1161078-9. (Anti seize?) This may be in the Haynes books: three step torquing method in an "X" pattern. (1) 1 Nm, (2) 45 Nm, (3) 45 deg angle tighten in one movement. I imagine this torquing method would only work if the bolts were lubed. (Reeks of bolt snapage.)

The former was not a reproduction of a Volvo service manual. It is in fact a translation and conveyance of information that I have gained.

Good luck!

Even with a Mitsubishi turbo there are bolts? They sure look like studs to me -- although I can't very well see the back of the flange (facing the engine) since the clearance is so tight. Hmmm... The FAQ mentions this special tool, and actually recommends a different torquing procedure than that which you've described. What year was the TSB released, and is it for Mitsubishi or Garrett turbos?

Thanks for the information -- those Green Books are the goods.

What I described to you is also in the 240. '76-'93 Haynes book. Definitely an earlier version of the turbo mounting. According to the Volvo web site TP31003/1 covered a very wide range of years up to 940, '95. Wrong! In addition to the turbo it covers the EGR, and cruse and that may be out of date too. Sorry for the confusion. I'll be contacting the distribution center.

The book covers "B230FT 1985" on. I agree, this must be an earlier version of the turbo mounting. I looked at my son's '95 B230FT and it is totally different from the book. Your are totally correct. There are threaded studs and nuts holding the turbo onto the manifold. This also may be a Garrett mounting rather than a Mitsubishi.

Thanks for verifying, Tom -- it'll help those who are just reading the post and gleaning the info for future reference -- and me!

Tool 5411. Get it from www.borton.com

You can alos kludge one together by having a welding shop weld a square drive on the end of a wrench.
