BVSmith Posted November 22, 2011 Share Posted November 22, 2011 I'm removing the heads on my '06 Legacy GT so I can check the valves. Part of the process is to remove the cam sprockets. I built a tool that keeps the cams from turning so I can control the torque on the bolts that hold the sprocket. The tool attaches to the cam sprocket via the 3 bolts that hold the bolt cover, then also attaches to the engine block. So the sprocket is held solid and I have access to the sprocket bolt. Problem is, the sprocket bolt is really tight. I'm pulling about 80 ft-lb counter-clockwise and it's not budging. The spec when installing the sprockets is 22 ft-lb, then add another 45 degrees. I can't believe that 45 degrees on top of 22 ft-lb can be this hard to loosen. Anyone had any experience here? Link to comment Share on other sites More sharing options...
frank_ster Posted November 23, 2011 Share Posted November 23, 2011 mine were stupid tight ! i had to heat mine i dammaged all of them trying to remove them i ended up ordering new ones , but the dummie at the dealer got me 4 of the intake ones with the hole through them instead of two of each. and i cracked a sproket ! i think there was lock tite on them. i figure there was about 200 lbs tq on them to crack them loose. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
bmx045 Posted November 23, 2011 Share Posted November 23, 2011 get the correct allen key 3/8" socket, blast it off with an air impact and hope to god it comes off. some don't even come off, at all. Link to comment Share on other sites More sharing options...
Lardo420 Posted November 23, 2011 Share Posted November 23, 2011 the cam sprocket and cam fuse together with that much torque. good luck man. Link to comment Share on other sites More sharing options...
frank_ster Posted November 23, 2011 Share Posted November 23, 2011 a good 1/2" impact could do the job. but just hold the sprokets well. Now that's thinking out of the boxer! fyi all 05 + legacy's have built in code reader Link to comment Share on other sites More sharing options...
