e46 M3 torque spec thread-- every bolt on the car on diagrams

[ac427]

Is the torque value for number 3 in this picture correct? I don't remember have any struggles removing these bolts and 74 ft/lbs is high. I tightened them to 59 so if I was wrong I need to retorque.

Just for clarity, 64Nm and 52Nm is the standard E46 M8 bolts torque rather than M3's M10 bolts, so the diagram is correct.

Great write up. I wanted to add that racing Diffs has different differential pinion preload and carrier backlash specs than what is given by TIS and metric mechanics.

pinion preload: 0.5-0.8 NM
careier backlash: 0.1-0.15 mm

I actually didn’t find any differential build specs in TIS and I checked MM’s diff booklet and those specs were listed generically, I’m not sure if they apply to all the diffs they build.

Thread dig but I thought I'd confirm this as I was checking up a few. TIS agrees with the diagram. Should be 100Nm / 74 ft-lb

E36 / Z3 2.8i, E36 / S50 / S52 / S54, E46 / S54, E85 / S54, E86 / S54

M10x46 10.9 (black)

Replace screws

100 Nm

Thank you for this as well, although I have a Bentley Hard Cover, this seems to have all the specs in an easier to find/look @ format

Thanks to Flow, back on M3forum:

Can we host the updated version of the file here, in case that site goes down... we all know that is possible :-)

Woohoo! Thank you so much for posting that first link! I am working on the power steering lines and that diagram really makes it simple and easy to find the torque values.

Your link shows the file as being in your 'trash folder' are you sharing a different version?

Weird. Works fine for me with the link in my post: (see first post)

[ac427]

Right, completely missed that. I've updated the date and updated the link to the file in my previous post.

Thanks for updating and rehosting. Any chance you can update the "Last updated" date on page 1 for config management?

I fixed the new (98 page) file with the correct torque specs for the caliper bracket bolts. Here's the file: (see first post)

I'm not sure if someone wants to verify this before adding to the PDF, but I think I found the torque values for the oil pump send and pickup tubes. I remember bimmerfan08 broke one of the M5 bolts trying to torque it to an approx. value. After cross-referencing the two bolts, I saw that these bolts are also used on the E36 and other E46 models.

According to the TIS for the E36 and E46, the M5x16 (number 6, pn 07129903041) is 5NM and the M6x16 (number 11, pn 07119904524) is 10NM.

S54 oil pump is on page 49.

The TIS seems to also state to wash and oil the replacement M10 rod bolts before installing.

Yeah really strange. Do you have the file that you took the screenshot from? I'm happy to host it somewhere for people to download.

The file I took screenshot from somehow has the INcorrect torque for the rears...it looks to be the same version as in the first post.
