fiveofakind Posted April 4, 2008 Share Posted April 4, 2008 I stopped by the Lexus dealer here in San Diego & had a chat with a Lexus mechanic..... Yes, they do use a special tool which they will not lend out nor sell ( I don't understand why they would not sell them --- it would be a cash cow for them ) The DIY way described by the mechanic that he sometimes uses is: 1. take an old drive belt, cut it short ( but to an appropriate length ), loop it around the crankshaft pulley & A/C Compressor pulley only with the two cut ends of the belt ending on the top side of the crankshaft pulley but under the belt. When you start to bust loose the bolt, the belt will tighten up & lock the cranksahft pulley & A/C pulley tight & not move.... Think about it...it makes sense..... I have not tried this method but would like to here the results if anyone has tried it..... OR 2. A 24" crescent chain wrench & an old piece of drive belt cut to length to wrap the crankshaft pulley... One of these two methods has to be the best method in lieu of having the SST tool that the dealer uses or the bump starter method.... What is everyones opinion ?????

gabep Posted April 4, 2008 Share Posted April 4, 2008 The torque you apply is going to be transmitted to the A/C shaft bearing. I would tie it off somewhere else. Quote Link to comment Share on other sites More sharing options...
caspergsx Posted April 4, 2008 Share Posted April 4, 2008 what i do is use my big breaker bar and 22 and lock it in the hole on the pass side frame and then bump the key to break the bolt loose ,, then use my 3/8 impact gun to install bolt ,, works great Quote Link to comment Share on other sites More sharing options...
ESpecial Posted April 4, 2008 Share Posted April 4, 2008 I just replaced my timing belt and the only way I could get it off was the bump starter method. Impact gun couldn't do it. This has been my experience in the past as well on other cars. Quote Link to comment Share on other sites More sharing options...
jbarhorst2 Posted April 5, 2008 Share Posted April 5, 2008 I used version #2 on my '97 SC300. Worked great. Quote Link to comment Share on other sites More sharing options...
