Stu Posted January 4, 2015 Share Posted January 4, 2015 I've never had any success with WD40 as a penetrating oil.......but Plusgas has got me out of several fixes in the past..... Interestingly a search on google for Plusgas throws up comparisons with WD40......in which WD40 doesn't come out too rosy..... But it seems that Plusgas isn't so easy to get hold of now, which is a real shame......but it is still around......and smaller motor stores may still stock it..... my dad has he did a full strip down of a 1972 land rover he went round and sprayed all the nuts and bolts with WD40 2 weeks prior to the strip down and sprayed them every other day out of the full strip down only 1 bolt had to be cut off ironically it was the one and only bolt that he missed with the WD40 I have also had success with it but as I say it needs time to work in and if time is not on your hands then its pointless Quote Link to comment Share on other sites More sharing options...
fullscreenaging Posted January 4, 2015 Share Posted January 4, 2015 Wd40 is the most mis used thing ever. Every one (I include myself) uses it as a penetrating oil. It's not that good at it either. Wd stands for water displacement and 40 was the number of attempts before they found something that worked. Lol Quote Link to comment Share on other sites More sharing options...
Harri Posted January 4, 2015 Author Share Posted January 4, 2015 I've emptied the WD40 today so I might as well go ahead and order plus gas from ebay and give it a try. Barcud Quote Link to comment Share on other sites More sharing options...
megawatt Posted January 5, 2015 Share Posted January 5, 2015 I don't use any penetrating oils on steel bolts stuck in alloy, I heat up the alloy and freeze the steel. I wouldn't hit that broken stud very hard or you may crack the crankcase. You need to recentralise the hole in the stud. I also don't use easy outs. I use a square file tang, the bit that the wooden handle fits over. The corners are sharper than easy outs and you can turn it with mole grips .

Harri Posted January 5, 2015 Author Share Posted January 5, 2015 Hi Mega, I couldn't re-centralise the bolt now as the hole is too big.The end of a file is a good tip. On a bolt this small and using the easy out, the problem is you are not able to get a good enough grip on the end of the easy with moles. The end is too small and eventually the grips slip! I will persevere but I do think this will end up a drilling out job which will be a pain in the butt Barcud Quote Link to comment Share on other sites More sharing options...
Grumpy Old Git Posted January 5, 2015 Share Posted January 5, 2015 You can re-centre the hole but it takes a bit of work to do it. Basically you need to make a guide from high-tensile steel plate and attach it (using the other bolts) and drive a decent drill bit (slowly) through the guide ito the bolt.This is best done on the bench (engine out) and then, once clear, helicoil insert.An alternative would be to drill and helicoil as is, 'move' the cover hole and fill the remaining space with alloy weld.Although I am surprised that WD40 (overnight soak); heat and an easy-out have not worked!

megawatt Posted January 5, 2015 Share Posted January 5, 2015 You need to extend the hole toward and past the centre until it is symetrical. I use miniature grinding bits or Dremel bits. You need to be very careful not to crack the casing. If you can't remove broken stud , you may just have to leave it alone. Quote Link to comment Share on other sites More sharing options...
Harri Posted January 5, 2015 Author Share Posted January 5, 2015 Hi, yes I'm very surprised that the bolt hasn't budged yet! Not even in the slightest! I have internet links that show this bolt can be a problem. But the force I have been using with the easy out is quite a bit and I'm no slouch! I thought the easy out might have snapped by now If you look at the place where the bolt is, at the top of the clutch housing, would it be a big problem if it was left as it is?Barcud Quote Link to comment Share on other sites More sharing options...
cockercas Posted January 5, 2015 Share Posted January 5, 2015 Your not ment to grip easy outs with mole grips. Your ment to use the correct tool. But i dont know what its called. It has square sides. Ebay easy out handle. Quote Link to comment Share on other sites More sharing options...
Guest Posted January 5, 2015 Share Posted January 5, 2015 This won't help you right now as the bolt is too far gone but for future reference, these are amazing (and would have removed the bolt in your case annoyingly...)Bolt gripping sockets.

Ricky Posted January 5, 2015 Share Posted January 5, 2015 This won't help you right now as the bolt is too far gone but for future reference, these are amazing (and would have removed the bolt in your case annoyingly...)Bolt gripping sockets. They're used for rounded off bolts, I fail to see how this would helped remove a snapped bolt? Quote Link to comment Share on other sites More sharing options...
Harri Posted January 5, 2015 Author Share Posted January 5, 2015 I was wondering about that. I had no trouble with my socket it was just this one bolt was stubborn and eventually it snapped. A common fault with this bolt on this engine Barcud Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted January 5, 2015 Share Posted January 5, 2015 is the hole blind or open at the back of the casing if its open its also worth filling that side up with plusgas as well so that it soaks in from both sides Quote Link to comment Share on other sites More sharing options...

They're used for rounded off bolts, I fail to see how this would helped remove a snapped bolt? If there was more of it revealed, a small socket would habe gripped it.Like I said in my original post "it doesn't help you now as the bolt is too far gone".

Harri Posted January 7, 2015 Author Share Posted January 7, 2015 Cheers Phil. Something useful to remember for the future.I've tried soaking in plus gas, heating up, and heaving on an easy out. All to no avail! I think I'm in trouble with this one and not sure what to try next. Anyone got a next step?Barcud Quote Link to comment Share on other sites More sharing options...
Tango Posted January 7, 2015 Share Posted January 7, 2015 I wonder if heating it up and then spraying some freezer spray down the hole you drilled would shock it enough to break its hold..... Quote Link to comment Share on other sites More sharing options...
Harri Posted January 7, 2015 Author Share Posted January 7, 2015 Hi Bob, I've been tempted to take a small drill bit to it to try and break it up. then tapping out another hole. But as pointed out it looks as if the hole has already been done before Barcud Quote Link to comment Share on other sites More sharing options...
