Right today's effort was also a faliure, i think we should set up a completely seperate forum for 'People who have gone insane when trying to undo the E20 Crank bolt' lmao
Today i had the block supported by my mate, and tieing the block to the thick steel pole that supports my car-port roof and garage door surround, and a big steel bar almost 5 ft long with me and my old man levering on it, needless to say the only piece of movement we had was when we either fell over when pulling on the bar or when the big steel pole holding up the carport started to bend!! lmao lmao
if you have electricty in your garage (I haven't) then this is the way to go, its quick and easy. All you have to do is grind off the head of the E20. You need to remove the red and orange areas below. The green section is actually a seprate washer, but its well in there and will proably never come out.
once the E20 head is off, you can remove the lower crank spigot wheel (as below). you'll still have the E20 thread still there but I grantee it will be lose and you'll remvoe the bolt with your fingers.
The bolt is quite long, but I got a new one for £7 from autovaux.
The problem is that the underside of the head of the E20 bolt corrodes, so its virtually welded itself to the face of the crank spigot wheel. The pic below shows mine removed and you can see a white circle where the head of the E20 was rusted on.
Already tried heating it up with the blow torch, once i can locate my angle grinder i'll attack it with that as i haven't made much progress on the block itself because of it. Topbuzz, thanks very much for your pictures, i was going to ask to make sure but thats confirmed it for me, it's going to come off today whether it likes it or not
