SharkyMarc Posted June 5, 2012 Share Posted June 5, 2012 Afternoon all, in the middle of doing all my bearings, and on the last corner the two caliper bolts are completely round! I haven't got a welder so weld a nut on, are there any ways people can think of of getting them out?? If anyone is around the redhill way and can help I'd be happy to give some cash in hand to get this done! Cheers in advance Quote Link to comment Share on other sites More sharing options...
Boris113 Posted June 5, 2012 Share Posted June 5, 2012 I would try to hammer a smaller socket on first, if that doesn't work then get the welding gear out. I had to do the latter with one of my calliper bolts. Quote Link to comment Share on other sites More sharing options...
zardos Posted June 5, 2012 Share Posted June 5, 2012 You could try getting yourself these type of sockets for rounded nuts/bolts, they have worked for me in the past. Quote Link to comment Share on other sites More sharing options...
taz90 Posted June 5, 2012 Share Posted June 5, 2012 try a 6 sided socket Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 5, 2012 Share Posted June 5, 2012 Aren't the caliper bolts 12-point heads? They are on my RRC. Quote Link to comment Share on other sites More sharing options...
SharkyMarc Posted June 5, 2012 Author Share Posted June 5, 2012 They used to be! Do those irwin bolt extractors work with 12 point bolts? Quote Link to comment Share on other sites More sharing options...
zardos Posted June 5, 2012 Share Posted June 5, 2012 Hmm, I've not tired them with 12 point bolts. Quote Link to comment Share on other sites More sharing options...
cjmt Posted June 6, 2012 Share Posted June 6, 2012 They certainly worked for me when one of mine rounded last year Charlie Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted June 6, 2012 Share Posted June 6, 2012 Try a 12-pointed socket, as they are 12 pointed bolt heads. Quote Link to comment Share on other sites More sharing options...
SPendrey Posted June 6, 2012 Share Posted June 6, 2012 ^^ What he said, and it they are truly rounded use the Irwin bolt removers, worked great for me! Quote Link to comment Share on other sites More sharing options...
Igol Posted June 6, 2012 Share Posted June 6, 2012 Irwin kit worked on many bolts for me in the past, only problem is I've knackered one and would have to buy the full set to replace it And DONT get the silverline version. Quote Link to comment Share on other sites More sharing options...
Igol Posted June 6, 2012 Share Posted June 6, 2012 And I've one to shift off mine next week so I'm hoping that the kit'll do the job then as well Quote Link to comment Share on other sites More sharing options...
simonr Posted June 6, 2012 Share Posted June 6, 2012 The Irwin type extractors will not work on Caliper bolts as the bolts are 12 sided and the extractors are 6. I'd recommend the next smaller socket trick and if that fails, stilsons will remove most things! I'm not far from Redhill if you need help.

mickeyw Posted June 6, 2012 Share Posted June 6, 2012 Marc, I'm in Horley if you would like a) to try an Irwin bolt extractor or, b) something welded to the bolt. Quote Link to comment Share on other sites More sharing options...
reb78 Posted June 6, 2012 Share Posted June 6, 2012 A 1/2 inch Irwin extractor worked on one of my 110 caliper bolts earlier today. I tapped it on gently with a hammer and then turned very slowly so as not to twist it off. The head of the bolt was almost rounded completely from my previous attempts to remove it! seems there are a few of us with the same problems at the same time!....: http://forums.lr4x4....showtopic=76882 Nowhere near enough room to get stilsons in there on my 110 Si. Not sure if there is on a disco though. Quote Link to comment Share on other sites More sharing options...
steve b Posted June 7, 2012 Share Posted June 7, 2012 I've used the Irwin extractors on rounded 6 and 12 point bolt heads and locking wheel nuts that were completely round where the key was broken/lost , very useful tool and grips whatever is left of a fixing ,providing the remains come within the size range of the sockets iirc Snap-on do a similar set. cheers Steveb Quote Link to comment Share on other sites More sharing options...
Tanuki Posted June 7, 2012 Share Posted June 7, 2012 From the factory, the bolts are retained to the axle-flange using a blue "Loctite" type threadlocking compound. As you've discovered, it's rather effective. I'd recommend getting some heat into the heads of the bolts before trying further removal. A good blast from a normal blowlamp for a few minutes will help break the threadlock's seal. And in future, use a proper 12-point bit. That's *not* the same animal as a 12-point bit for a traditional hex-headed bolt. . . --Tanuki. Quote Link to comment Share on other sites More sharing options...

Bowie69 Posted June 7, 2012 Share Posted June 7, 2012 I've always used a normal, good quality 12-point socket without issues... Quote Link to comment Share on other sites More sharing options...
simonr Posted June 7, 2012 Share Posted June 7, 2012 To be fair, my bolt extractors are Snap-on, not Irwin - and they did not work on Caliper bolts. However, I had some small Stilsons which did work, though it was tight. This was on my 110 (never owned a Disco). Si Quote Link to comment Share on other sites More sharing options...
Tanuki Posted June 8, 2012 Share Posted June 8, 2012 Have you got any links Tanuki? They're called "Triple-swuare" or "XZN" heads. Often also found on things like big-end/main-bearing caps.See http://www.brimarc.com/products/Proxxon-12-Sockets-for-XZN-Screws-855568.htm Quote Link to comment Share on other sites More sharing options...

UdderlyOffroad Posted June 8, 2012 Share Posted June 8, 2012 Slightly O/T but still related: Can anyone tell me the size/point me to a linky of the socket I need to strip an early 110 front axle. There appear to be these triple-square bolt thingies holding the cv/balljoint housing to the main axle itself. I'm going to do a front axle strip next w/e and I'd rather try to undo them with the correct thule rather than waster hours trying drill out snapped ones....

Bowie69 Posted June 8, 2012 Share Posted June 8, 2012 9/16" ring spanner and a hammer, if they are a little corroded use a 14mm spanner (very slightly smaller) and tap the ring of the spanner in place. You won't get a socket on, not enough room to the ball. Quote Link to comment Share on other sites More sharing options...
