Phil and Lol Posted May 28, 2016 Share Posted May 28, 2016 I have a Autotrail Comanche, what would you set a torque wrench to, in either Newtons or Pounds, when tightening wheel nuts. Link to comment Share on other sites More sharing options...
Robbo Posted May 28, 2016 Share Posted May 28, 2016 Depends what size wheels you have. Different torque for 15 or 16 inch wheels. Link to comment Share on other sites More sharing options...
Tracker Posted May 28, 2016 Share Posted May 28, 2016 Should be clearly defined in the Fiat handbook, or a Google search if you don't have a handbook, or a phone call to a Fiat dealer quoting the chassis number and year. Link to comment Share on other sites More sharing options...
W3526602 Posted May 29, 2016 Share Posted May 29, 2016 Hi, If you refit an aluminium wheel, the nuts should be re-torqued after 100 miles (or whatever). Some garages will insist that you sign a disclaimer. 602 Link to comment Share on other sites More sharing options...
Billggski Posted May 29, 2016 Share Posted May 29, 2016 Just had two new tyres on my 15" alloys, Mr Tyre were very professional and looked up the setting. 180Nm. Link to comment Share on other sites More sharing options...
Derek Uzzell Posted May 29, 2016 Share Posted May 29, 2016 Tracker - 2016-05-28 9:38 PM Should be clearly defined in the Fiat handbook, or a Google search if you don't have a handbook, or a phone call to a Fiat dealer quoting the chassis number and year. One might reasonably believe that any of those options would provide a uncontroversial answer, but this earlier discussion will show that - at least where the current Fiat Ducato is concerned - this ain’t so. http://forums.outandaboutlive.co.uk/forums/Motorhomes/Motorhome-Matters/Fiat-Ducato-X290-wheel-bolt-torque/38394/ As current (X290) Ducatos can now have 15” or 16” diameter wheels as original equipment (OE), the simplest policy would seem to be to tighten the wheel-bolts according to the specification of the bolts rather than according to the diameter of the wheels. Consequently M14 bolts would be torqued to 160Nm/118ft.lb and M16 bolts to 180Nm/133ft.lb and (as far as I’m aware) those settings would apply irrespective of whether OE wheels are steel or alloy. Phil and Lol’s inquiry relates to a 2011 Auto-Trail Comanche (built on a tandem-rear-axle Al-KO ‘heavy’ Ducato chassis with 16” diameter wheels attached via M16 bolts), so the recommended torque-setting will be 180Nm/133ft.lb (As a follow-up to the 2015 forum thread I provided a link to above, when 16”-diameter OE steel or alloy wheels are specified for a Ducato X290 ‘light’ chassis no changes are made to the hub assembly. Thus a Ducato ‘light’ chassis will always have M14 wheel-bolts irrespective of the diameter of its wheels.) Link to comment Share on other sites More sharing options...
Phil and Lol Posted May 29, 2016 Author Share Posted May 29, 2016 Thanks for the info, I had looked in handbook which only mentioned 'using spanner provided'. This forum proves its value yet agin. Cheers Link to comment Share on other sites More sharing options...
