engine and drivetrain torque question

[Guest Anonymous]

i recently did some major work. i assembled a new crate motor, rebuilt 5spd transmission & suspension on a subframe and did a swap. I had planned on spending tomorrow doing:

---== !=D.A.N.G.E.R. !- A.C H T U N G =! ==---

DO NOT DRIVE ANOTHER FOOT UNTILL YOU

LOCATE THE SOURCE OF THE NOISE!

LOOK, AND PUT A WRENCH TO EVERY NUT ,

BOLT ON THE SUSPENSION, STEERING ,

CALIPER MOUNTING BOLTS,

BOTTOM SAFETY WIRED BALL JOINT TO STRUT

BOLTS ! - ALL OF THEM !

because I value my life, the other drivers on the road (and my car). the only torque spec i have not been able to find is the subframe to car bolts. the six or three on either side that actually hold the subframe to the chasis.

any help would be greatly appreciated. also since it's a fairly long process and i did really "build" everything forward of the firewall does anyone have any suggestions as to where to look for things loostening?

TIA

I think it's about 150lb/ft, but I'm not sure.

in the strut bearings? That is often done incorrectly and causes the sound you mention.

I'm looking for the torque spec for 07 1 19 913 859 shown below on realoem.com. There is no related noise or issues however as I previously stated. I performed a LOT of work on the car and now that it's been a few hundred miles I want to make sure I'm not risking my life or the lives of others by driving. This is the ONLY thing from my entire project that keeps me up at night worrying that I over/under torqued it.

Any help would be greatly appreciated. I do not know where else to look. Of all people I would have figured that CD would know the answer to this???

Steve,

I do not believe it's there. I have looked through the chart and would not have asked without looking. The only thing that is close is "Fron axle beam to engine mounting" which sounds more like motor mounts to me than subframe to chasis bolts.

I have looked here, asked at three dealerships, in the HTK, Haynes, Chilton, Bently, etc...

Any help would be appreciated.

Thanks

hmm, you are right. i guess we cannot have it all

should have looked first. hopefully someone knows and we kan add it to the chart.

I looked in the E21 factory manual since I couldn't find it in the 02 manual and there it shows 32-35 ft-lbs for 'front axle carrier to body'. Should be close enough for 02s.

Sorry I don't know about your problem guest, but Steve another one missing from the chart are the Tii intake manifold torques .. They don't seem to be in any of the usual manuals or even in the blue book (that I could find) either

Just in case someone is researching torque settings for the FAQ have a look for that one too

That spec is listed on the chart, but it is easy to miss due to the wording.

"Fron axle beam to engine mounting" is taken from the Shop Manual.

"Front axle carrier to engine carrier" is the language BMW used elsewhere, as in the 2002 owner's manual.

Front axle obviously is the front SUBFRAME.

Engine carrier is actually their name for the FRAME RAILS.

Refer to the frame rail description in the paper parts book, it's called "MOTOR BEAM" in the english. The HTK uses the term "ENGINE SUPPORT", but you get the idea.

34 ft lb is the correct tightening torque for all six bolts that attach the front subframe to the frame rails. Each side has one M10x50 in the front hole, and the rest of the bolts are M10x30.

Looking at the FAQ's list for tightening torque, I'm seeing that Rob gave me credit for some "translations" in the text, which is cool except some of the words got changed from the original message board posting I had used them in. That, and there are some other terms that could use clarification.

Track rod arm at kinpin (steering rod)

I'd say "Steering arm safety bolts (3) at bottom of strut".

The track rod is the steering arm that attaches to the bottom of the strut with the three safety-wired bolts. The kingpin, in this case, is the lower part of the strut housing that has the knuckle/spindle. I'm calling the track rod arm a steering arm, which will be confusing because BMW uses that name for the Pitman arm that attaches to the steering box! I had never used the term "steering rod" in the text I posted.

Trailing link at whishbone and axle beam (radius arm connecting outer end of control arm to front of subframe)

For this I'd change the term radius arm to strut rod

In these specs for front suspension & the steering section, there are a lot of terms that have more common names in the US.

Steering arm at steering box could be called a Pitman arm

Kingpin can be called steering knuckle

Wishbone = lower control arm

Track rod = Either a tie rod or center link or drag link
