Small Torque

Now then...

Technical question if I may.

From the Mercedes/Smart WIS (electronic manual) various torque specs are spoken as initial torque then final torque but the application of the values is confusing me.

There are no instructions, just the values.

For example the oil pickup pipe on my vehicle is shown as initial torque of 12nm and a final torque of 9nm.

Now is that just going back over the fasteners after the 12nm and any needing nipping up only go to 9nm or do I back them off slightly and re-torque to 9nm?

Help...

I wouldn't bother with torque settings for stuff like that, 1/4" drive ratchet or a T bar for owt M6 just nip it so it's tight.

I agree with that common sense approach Stealthstylz & for the majority of fasteners that's how I would go anyway...but what do they mean? It makes no sense without instruction.

Not a clue lol, I do sometimes notice some errors on autodata torque setting continuity but that seems like a odd one.

I only ever recall coming across this when the final torque is the higher figure, which to me makes perfect sense...this, on the other hand, has me stumped. Could it just be round the wrong way?
