Guest Posted July 27, 2002 Share Posted July 27, 2002 Hello All,<P>This does not seem to be my year. You may recall my post a few months ago with a broken bolt on my water pump. Well now its the carb bolts turn to be a PITA. One of the two front base bolts on the carb snapped.<BR>Does anyone know what these look like ?? Based on the piece that broke off it looks like a normal 1/2" hex from the top - but the shaft looks to be extremely thin. Is it that mine has rotted away with the years or are these really very thin bolts ???<P>I have a 401 eng - 2 bbl.<P>Thanks<P>Thanks Link to comment Share on other sites More sharing options...
Guest Skyking Posted July 28, 2002 Share Posted July 28, 2002 Ira, the bolt in question is a 5/16-18. I broke one on my 401 also and had to drill and use an easy-out to remove it. It wasn't that hard to do.....Good Luck! Link to comment Share on other sites More sharing options...

Guest Posted July 28, 2002 Share Posted July 28, 2002 If you go the easy-out route BE CAREFUL. It does not take to much force to break them and if you do - they don't drill out. They are made of some very hard steel. Link to comment Share on other sites More sharing options...
Guest Posted July 28, 2002 Share Posted July 28, 2002 Well - Now I have 2 broken.<BR>Both of ones on the front of the base.<BR>From the looks of them though - I never stood a chance no matter how long I soaked. They virtually crumbled in my fingers and the shaft is withered away to something very thin. They are in such poor shape that I might be able to "disintegrate" the remaining portion with a regular drill bit.<P>I'll let you know how it works out !<p>[ 07-28-2002: Message edited by: Ira ] Link to comment Share on other sites More sharing options...
brad54 Posted July 30, 2002 Share Posted July 30, 2002 I always see something like this as an excuse to upgrade to a new intake and carb!<P>I've heard of left handed drill bits also, to drill prior to the EZ Out. Sometimes these bits will actually back the screw out for you. A standard twist drill bit can actually make the busted bolt tighten up further.<BR>Also, he was right about not breaking the EZ Out--the only substance on earth harder than a diamond is a busted EZ Out!<BR>-Brad Link to comment Share on other sites More sharing options...
Guest Posted August 10, 2002 Share Posted August 10, 2002 After a bit of a hiatus - I'm back at trying to remove the bolts. I bought an extractor kit from Sears - which I do not reccommend. The things dont work. Basically - they drilled off the stub that was sticking out and also began to remove a bit of the bolt from insie the manifold. These are supposed to be extracors - but they behave like ordinary reverse thread bits - and they were more than $40 - definitely going back.<P>Now I'm pretty much left with only one option - to drill out the remaining bolts from the intake manifold. The one on the right concerns me a bit. The way the manifold is constructed it passes through the manifold and extends through to the inside - which means that as I drill it out - all of the iron filings are going to drop inside the intake manifold. I'm not a mechanic - but that doesn't sound like a good thing to me. The one on the left is not constructed like this so I should be okay.<P>What I'd really like to do is pull the intake off and take it to a shop & have it drilled, retapped & washed - but given my miserable luck with removing bolts - I'm not going anywhere near the 8 that secure the intake !!! Not unless the thing cracks in half !!<P>Anyone out there have any experience with this ?? All suggestions are appreciated.<P>Ira Link to comment Share on other sites More sharing options...
Guest Posted August 11, 2002 Share Posted August 11, 2002 before drilling- grind studs flush w/ manifold-then center punch, then drill, then easyout. Link to comment Share on other sites More sharing options...
Guest Skyking Posted August 11, 2002 Share Posted August 11, 2002 While drilling, keep a magnet close to the drill bit to catch the chips from going inside....... Link to comment Share on other sites More sharing options...
Guest Posted August 11, 2002 Share Posted August 11, 2002 At any point have you used a torch?? I have a MAPP gas one that I bought at Home Depot for about $40. I have used it numerous times. Push a button - it lights. Always heat around the bolt, and I have heard to heat - throw cold water - heat - throw cold water is a good method. If you don't have this torch - get it.<P>I don't have any experience with drilling out broken bolts. I tried to get one of them out with an "easy-out" but did not have any luck. It broke - and then your dead. Link to comment Share on other sites More sharing options...
