BlackSC4 Posted December 25, 2003 Share Posted December 25, 2003 hi, for all the mechanics that have changed timing belts, how the **** do i take off the crankshaft pulley bolt. that thing is in TIGHT and does not want to come out. impact gun doesnt work either, will an air compressor do? after i get it out, how do i apply that much force back in to tighten it again??? thanks for any help!

johnny3 Posted December 25, 2003 Share Posted December 25, 2003 The bolt face & pulley face get their surfaces mated up against themselves so well they just become "stuck" & you can't hardly twist the bolt loose in the conventional way. You need a stronger impact wrench,over 200 lb. torque. Another way I've done it is to take a acetelene torch, heat the bolt head red, let it set (soak) about 1 min., then you can turn it easily, heat makes the bolt get longer (expands long ways). Good luck Quote Link to comment Share on other sites More sharing options...
BlackSC4 Posted December 25, 2003 Author Share Posted December 25, 2003 i see...can i use butane gas torch? and how do those dealership guys do it...removing a 239lb-ft bolt like that. Quote Link to comment Share on other sites More sharing options...
UCF3 Posted December 26, 2003 Share Posted December 26, 2003 No, don't use a butane torch. Use the impact wrench. 200-250lbs sounds right. If you can't get to it, WD40 it, and use the right tools. Quote Link to comment Share on other sites More sharing options...
BlackSC4 Posted December 26, 2003 Author Share Posted December 26, 2003 i've been using a 217lb torque impact wrench...doesnt even move it. so what i did was i found a socket wrench big enough to fit the fat bolt and wrapped the wrench with a thick pipe and let it land onto the floor then cranked the starter. popped right off.

UCF3 Posted December 27, 2003 Share Posted December 27, 2003 Interesting. I wouldn't have cranked the starter, just use a lot of elbow grease, but you did it. Congrats. :) Quote Link to comment Share on other sites More sharing options...
BlackSC4 Posted December 27, 2003 Author Share Posted December 27, 2003 yeah thanks, but now i have to tighten it back to 239lb-ft. Quote Link to comment Share on other sites More sharing options...
johnny3 Posted December 27, 2003 Share Posted December 27, 2003 If shop impact wrench won't break it loose they use a "slugger" type wrench or heat it with an aceteline torch like I discribed. Quote Link to comment Share on other sites More sharing options...
UCF3 Posted December 27, 2003 Share Posted December 27, 2003 Yeah, I've seen some shops using an open-head wrench and a thick metal sleeve, and pull. BlackSC4: Why are you torqueing it to 239lbs'? you should just tighten it so that it stops any leaks, or else change the bolt. Quote Link to comment Share on other sites More sharing options...
