Magnificent - one of the most helpful forum posts I've ever seen.

(I've only got a 325i, but still...)

Just following up on the previous post in this thread - does anyone know the correct torque for the thrust bearing : cylinder head. It’s for the five 8.8 M8 bolts.

Anyone know the torque spec for the thrust bearing flange to the cylinder head? There's a good chance I'm blind and missed it, but I didn't seem to find it in the file

This is great to have - thank you to the forum and contributors!

Wow, this is amazing.

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

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

[Johnvu]

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.
