Peter T Posted June 17, 2002 Share Posted June 17, 2002 I am going to replace my rear disks tomorrow and need to find out what size the nuts are, also i take it that one is left handed thread, is it the nearside that has this backward thread?

tony pashley Posted June 17, 2002 Share Posted June 17, 2002 41mm. The one with the white nyloc hoop is RH, the green one LH; but you can tell be checking the exposed thread at the end of the shafts. If they've been in use for any length of time, expect them to be a bit of a pig to get off. Link to comment Share on other sites More sharing options...
Paul McKenzie Posted June 17, 2002 Share Posted June 17, 2002 41mm Can't remember, but I think they're colour coded or obvious Paul Link to comment Share on other sites More sharing options...
Peter T Posted June 17, 2002 Author Share Posted June 17, 2002 Thanks Tony, any idea as to what torque they should be wound up to? C7 PWT X-Flow all Steel Life begins at 40(00rpm) Link to comment Share on other sites More sharing options...

Paul McKenzie Posted June 17, 2002 Share Posted June 17, 2002 200 lbs ft. Are you guys watching University Challenge? Paul Link to comment Share on other sites More sharing options...
Miff Posted June 17, 2002 Share Posted June 17, 2002 200 lb/ft, just remember to check the torque wrench you hired from the local shop works on both directions! (i.e. don't hire from brandon hire in banstead) Link to comment Share on other sites More sharing options...
tony pashley Posted June 17, 2002 Share Posted June 17, 2002 200 lb ft. is the quoted figure. That's a lot and you need quite a hefty torque wrench for that. Link to comment Share on other sites More sharing options...
Paul McKenzie Posted June 17, 2002 Share Posted June 17, 2002 Tony, Are you ex-Oriel College, Oxford - if so I saw you tonight on TV, but I guess it must be pre-recorded! Paul Link to comment Share on other sites More sharing options...
John Vine Posted June 17, 2002 Share Posted June 17, 2002 My wrench only goes up to 150 lb ft so I borrowed a 200+ wrench from the local ATS place. Very helpful guys (especially when they discovered what the car was). JV Link to comment Share on other sites More sharing options...
tony pashley Posted June 17, 2002 Share Posted June 17, 2002 I normally watch Uni Challenge - but forgot tonight. I'd have had a shock if I'd seen that - but no, I didn't graduate from such an esteemed college. (Not even red brick me, more glass, steel and concrete.) So who was the doppelganger? Is he someone I'd be proud to be mistaken for? Link to comment Share on other sites More sharing options...
Peter T Posted June 17, 2002 Author Share Posted June 17, 2002 Damn, no make that double damn, the largest socket that i have is only 38mm, also my poor old torque wrench only goes to 150lbft, Aghhhhhhhhh. Any one willing to hire or lend the two for a good cause? (Beer tokens gladly given) C7 PWT X-Flow all Steel Life begins at 40(00rpm) Link to comment Share on other sites More sharing options...
Paul McKenzie Posted June 17, 2002 Share Posted June 17, 2002 No Tony, only joking ...it was the speed and synchronisation of your answers with mine that reminded me of the aged contestants on UT, which I was watching at the time in the guise of an aged viewer.

John Vine Posted June 17, 2002 Share Posted June 17, 2002 I too have a 41mm socket (plus 3/4" to 1/2" adapter). Is Petersfield, Hampshire anywhere near you? JV Link to comment Share on other sites More sharing options...

tony pashley Posted June 17, 2002 Share Posted June 17, 2002 Ah - I figured there was some jesting in there somewhere, but someone told me they'd seen a Pashley on U.C. a long time ago and I wondered if this was the same character resurfaced! Not the commonest of names.. unless you're a Yorkshireman (which I'm not, btw). A lot of people ask if I'm the hillclimber of the same name. Peter - I've lent my hubnut socket to a Sierra owner (?!), but I'll see if I can get it back soon... where are you? Think your biggest prob may be getting the old ones off, rather than rounding up the kit. (I have heard of them being removed very easily with a compressor-driven impact wrench, but I can't help there). They seem to tighten considerably in use and can sometimes need you to have the car on the ground, handbrake hard on, in gear, wheels chocked, tyre deflated a bit and a very big breaker bar on the socket with a short socket extension to rest on an axle stand to stop the socket slipping off the shallow nut. I helped to do this a while back on another 7 and the nyloc insert had kind-of fused onto the shaft and the force needed to turn it was staggering (literally). I had too stand on a chair and let all my weight (well all 11st of it) drop on the end of a 24'' bar just to turn it less than a flat-at-a-time. I hope you don't have that much trouble, but be warned! The torque wrench I have (which you are welcome to borrow if practical) is huge (30'') so gives a fairly easy pull, but at about 240 lb ft max, it's no good for removing them.

stevefoster Posted June 18, 2002 Share Posted June 18, 2002 Most motorfactors do the 41mm socket 1/2" drive for about £6. It is a common Sierra being worked on Sunday afternoon purchase... You may need to get someone to put the brakes on hard while you undo.

Harry Flatters Posted June 18, 2002 Share Posted June 18, 2002 I live in Carshalton in Surrey and have a socket and torque wrench to suit. Steve Mell PTM 88 Link to comment Share on other sites More sharing options...
Peter Carmichael Posted June 18, 2002 Share Posted June 18, 2002 My socket and breaker bars are currently in... ...Epsom. I am of the reasonable belief that if I stand about a foot away from the fulcrum on a breaker bar I get the required torque.

John Vine Posted June 18, 2002 Share Posted June 18, 2002 I think I quoted the green and white nylocs the wrong way roung, btw... According to my Assembly Guide, the LH nut is plain and the RH is green (and the LH nut has a LH thread). Final tightening is best done with the car on its wheels and the brakes applied.
