IanT90 Posted June 29, 2015 Share Posted June 29, 2015 I am in the process of fitting a new steering box and have just come to fit the drop arm and realised I don't possess a socket large enough and don't have a clue what size to get ? Searched the internet but all I get is its a nut and the part number NH614041. Anyone got any idea what size it is and where in the Wigan, Warrington or St Helens area I can get one ? Need to close the job off by Wednesday as I am back on shift Thursday and won't get the chance and the old girl is due back in the garage for her MOT re-test next Monday. Any help much appreciated Ian Quote Link to comment Share on other sites More sharing options...
Eightpot Posted June 29, 2015 Share Posted June 29, 2015 Don't know the size off the top of my head, but I've used a set of stilsons and a length of tube in the past to tighten these up to good effect - needs to go on VFT Quote Link to comment Share on other sites More sharing options...
IanT90 Posted June 29, 2015 Author Share Posted June 29, 2015 Presume that's very firmly tight Sadly its one tool I am missing (Stilson's) besides the correct socket for the job. I know how have I survived so long without a pair ! Tried the biggest spanner size I have 32mm and it's just a little too small. Suspect the nut is imperial anyway.

dantastic Posted June 29, 2015 Share Posted June 29, 2015 34mm Just did mine recently. It's very very tight tho... Quote Link to comment Share on other sites More sharing options...

daveturnbull Posted June 29, 2015 Share Posted June 29, 2015 I did go to the lengths of finding out the correct size, and buying an imperial socket for it it 3/4" drive flavour. I'll have a look this evening see if I can find it in the dumping ground workshop. Quote Link to comment Share on other sites More sharing options...

IanT90 Posted June 29, 2015 Author Share Posted June 29, 2015 All I have to do now is find a local tool supplier. Realised it was a tight one Torque setting is 179NM, everyone warned me it was difficult to get the old one off so ordered a new one. If I do manage to get the old one off before I send my old box to the refurb. company (its an exchange) I may stick it on Ebay or just keep it for the future when spares get rare. Very grateful for all the help, thanks again. Quote Link to comment Share on other sites More sharing options...
landroversforever Posted June 29, 2015 Share Posted June 29, 2015 33mm :-) bought a socket specifically for it a few years ago Quote Link to comment Share on other sites More sharing options...
Boydie Posted June 29, 2015 Share Posted June 29, 2015 Yeah, a 33mm should fit it if the nut is a tad corroded (fancy that on a Land Rover?) but the 1+5/16" is a better fit. I used a nut splitter on mine to break the original nut and replaced it with a new S/S Nylock nut after, with a torque setting of 180NM -- just how you adjust to 179 is beyond my understanding - even my most accurate 3/4" torque wrench doesn't have that sort of graduations!

western Posted June 29, 2015 Share Posted June 29, 2015 you can if you have a torque analyser, like these http://www.ebay.co.uk/itm/like/251727302025?limghlpsr=true&hlpv=2&ops=true&viphx=1&hlpht=true&lpid=108&chn=ps&device=c&rlsatarget=&adtype=pla&crdt=0&ff3=1&ff11=ICEP3.0.0-L&ff12=67&ff13=80&ff14=108&ff19=0 Quote Link to comment Share on other sites More sharing options...

Probably A translation from an imperial measurement, although that works out at 132 ft/lb which is equally difficult to set. The workshop manual often shows a range of acceptable torque for fastenings, along with a newton metre translation range resulting in some bizarre figures to work with.

landroversforever Posted June 29, 2015 Share Posted June 29, 2015 33 is a perfect fit on a brand new one too Iain! Quote Link to comment Share on other sites More sharing options...
Boydie Posted June 30, 2015 Share Posted June 30, 2015 Yes LRF, I'd guess that a 33mm would be a tight fit over a 1+5/16" nut, but, that said the right spanner is always the best option and I still stick by my original comment regarding 179nm - or 132ft/lb - why wouldn't you set your torque wrench at either 180 or 130 -- the difference is not worth bothering about especially as you would put a dab of Loctite on the thread as well.

oneandtwo Posted June 30, 2015 Share Posted June 30, 2015 Halfords sell 34mm 1/2" drive impact sockets reasonably priced if you are stuck. I know this as I needed one as I had a bit of play in my steering appear while away on a trip once and the complete opposite from everyone else had happened - the drop arm had worked loose!
