Peter, thanks again for your interest and help.. The adjuster was originally installed correctly and worked just fine. As previously repoted, the retaining ring on the bottom of the adjusting screw broke due to over torqueing. I have found the answer to my original question about removing the adjuster assy.....it cannot be pulled out from the entry hole. Apparently the power stearing pump has to be removed to access the housing for the idler pulley adjusting assy. Looks like a rather formidable task!
