Torque setting for con rod nuts? - Ben - 01-11-2012 Need the torque setting for the connecting rod nuts. In the Haynes it gives a setting for 'big-end bearing cap nuts', which is 20Nm and then 70 degrees. But I thought big end bearings were the crankshaft bearings. There isn't any other settings which could be either of them though. Also should I be using locktite or simular? Seems a bit strange that important nuts aren't lockers, especially when they are in oil.. RE: Torque setting for con rod nuts? - ginge191 - 01-11-2012 Which con-rod nut settings are you after if its not for the crank end? have i missed something...? I'll browse servicebox, might have some interesting specs on there RE: Torque setting for con rod nuts? - Ben - 01-11-2012 Yeah it is the crank end. I meant that I thought 'big end bearings' referred to the 5 crankshaft bearings. Just found a setting for 'main bearing cap bolts'. I assume that's the crankshaft one.. Looks like 'big end bearing cap nuts' is referring to the conrods then. RE: Torque setting for con rod nuts? - ginge191 - 01-11-2012 Yeh i'm looking at the same thing on servicebox.. Can only get the spec for the bolts themselves, no torque settings, if any use :/ RE: Torque setting for con rod nuts? - Matty - 01-11-2012 That's correct Ben. (big-end bearing cap nuts is what you want.) I didn't use locktite. Someone will be along to correct me no doubt. haha. RE: Torque setting for con rod nuts? - Ben - 01-11-2012 Cheers for the replies guys, ill crack on in the next few days then RE: Torque setting for con rod nuts? - Ricky - 01-11-2012 There's a thread on here somewhere with the torque setting from Autodata, it's different to the Haynes manual. RE: Torque setting for con rod nuts? - Ben - 01-11-2012 Hmm so which do you trust?! Il have a look for the thread RE: Torque setting for con rod nuts? - Ricky - 01-11-2012 I used Autodata setting, it was like 50NM or something, I will have a look. EDIT: CLICKY RE: Torque setting for con rod nuts? - Matty - 01-11-2012 Yea, autodata says 50Nm, that's it. I did mine at 20 Nm + 70 degrees when I had mine... EDIT: Look below at "Possibly Related Threads..." RE: Torque setting for con rod nuts? - Ben - 01-11-2012 Not sure which to use really. Is Autodata a reliable source? RE: Torque setting for con rod nuts? - Matty - 01-11-2012 Well, it's what a lot of garages use for their data/information. Not sure if it's a reliable source though, but I'd imagine it is to be honest... If it was me, I'd be doing 20Nm + 70 again. But meh, that's me. RE: Torque setting for con rod nuts? - Ben - 01-11-2012 Oki doke, ill just use which ever takes my fancy when it comes to tightening them up. Cheers for the replies RE: Torque setting for con rod nuts? - Ricky - 01-11-2012 I can't see there being too much difference in the final tightness between the two anyway. But I would/did choose autodata. RE: Torque setting for con rod nuts? - Dave - 01-11-2012 Always done mine as per haynes, 20 + 70 I think. Your thinking of main bearings, which is crank. But the ones you need is big end bearings RE: Torque setting for con rod nuts? - Ruan - 03-11-2012 Big end caps are the conrod caps yeah, it's main bearing caps that bolt to the block |
