Torque

[Nick 0]

Got to tighten the flywheel to the block tonight, but im 99% certain it needs to be tightened to certian 'tightness' or pressure.

 

Assuming this is done with a 'torque wrench' but i was wondering if anybody can tell me how tight its got to be, or where i might find such information.

 

I will have to do the same for the driveshafts too, but was thinking as it was undone using a spline set, surely ill need a spline socket torque ratchet? Any information would be greatly appreciated!!

...a spline socket torque ratchet?...

:? I just use a splined drive in it's 3/8 drive socket, you could use a torque wrench but I've only ever just tightened them by hand with a normal ratchet.

Really...?

 

Why am i under the impression that these things need to be tightened to certain pressures? :scratch:

 

Your wheels have never fallen off have they? Or your clutch popped off...?!

there is a torque setting for pretty much everything shaggsy but i think if you go 90degrees or quater turn past tight this will be fine! iirc on the mk6 escort that we done recently it was 19nm

 

but like davidwort anything like water pump and brackets etc i do them with a ratchet untill i cant do them any tighter with my hands that usually works it is only with wheels and brakes etc i make sure i have the proper torque settings and

spanners 'should' be the right length to get the right torque for most bolts, with the exception of bolts that go into softer alloys.

I do use my torque wrench for wheel bolts and I've even been seen using them for the suspension legs, but driveshaft splines are just to much of a pain to get at, I might have checked one or two, but soon realised I'd got them about right anyway.

Main engine parts are another thing altogether, I wouldn't guess at flywheel bolts, most of my torque settings came from Haynes, dread to think of what miss-prints there might be! - but my clutch is still in one piece :-)

 

 

the attached is for a golf, posted on club gti forum, god knows what the exclamation mark is for!

I would ALWAYS torque engine related bolts/nuts, especially rotational parts and also the driveshaft bolts.

 

I've seen a few Golfs over the years where the spline bolts have fallen out and punched a hole in the diff casing because they were torqued up properly.

You can easily get a small 3/4 drive torque wrench down there. The Halfords professional wrenches (black body with orange grips) are superb. Got a couple of them (a big un and a litlun!) and they're brilliant 8) Lifetime guaratee too.

 

There's no excuse for not torquing bolts, there is always the tool for the job ;-)

Cheers for the replies, and esp the table. Its printed out so ive no excuses for if it falls apart!
