Crankshaft bolt torque

[jinjur]

Hi gang,

I have a crank pulley to replace and was wondering if anyone can give me the torque settings i need to re-tighten to?

I have a new bolt, the original was prob fine as timing was done not so long ago but for a few quid, i though just replace

Now, I only have a torque wrench in lbft and have no dials for angles so has anyone just done this using torque alone or are the angles required?

40Nm + 110deg i think.

Equates to roughly 130-140Nm, but how exact that is i don't know.

Don't forget to lock the flywheel.

Thanks James...........that is one thing that is on my mind as I was expecting to use the crank locking pin but worry that it isn't up to those torque values.

 

[JamesBryan]

Don't use the locking pin to hold it while torquing! You'll snap it off, then you're fucked.

Big flat head screwdriver through the back of the gearbox bellhousing, use that.

I hear you James....had a look the other day and thought I could use a crow bar to hold the crank through the timing hole (where the crank sensor lives)

I assume you are thinking of somewhere else? I was hoping to not have to pull the starter (trying to keep the job as light as possible as not well)

Ahh, sorry........being thick

 

[JamesBryan]

Don't have to pull the starter out, look closely near the driveshaft ?

I've used my crank pin God knows how many times to torque crank bolt and it's fine.

It'll always be fine until the time it's not ?

 

[jinjur]

Well......who'da thunk it.

I just found the MOT 582-01 (BGS version) crank locking tool that I bought when I bought the Renault timing tools (genuine) as I thought I might need it............totally forgot.

Monday is at least a bit better now

[JamesBryan]

Can't fit MOT 582-01 without removing the gearbox can you?

 

[jinjur]

Really? Aww crap....I thought from the manual it could be used with the gearbox on

It's possible, never seen one though so i don't know how it mounts.

Me too, the genuine crank pin handles it no bother.

Is this ok to do for removing the crank bolt also?

I'll be doing mine soon and my main worry is that if I remove the locking pin while I jam in a screwdriver to lock the crank to loosen the nut, how the hell do I get it back to the correct position once the crank bolt has been removed?

I suspect that when jamming the screwdriver In and applying torque that the crank will move slightly meaning that it's a pain to get the locking pin back into position.

I use mine and it's been fine, wouldn't like to guess how many times it's been used over the years.

Really lol, without even jamming the fly? I can see me having a go and bending the bloody pin lol

Good to hear the Pin is enough but i'd be using a screwdriver as well just as an insurance.
