In googling around on this, I found the following advice: "One last thing, even if you are not using the mechanical fuel pump, install the fuel pump drive anyway. It will keep the cam bolt from loosening up. Also, the drive pin in the cam sprocket must be 1 5/8" long and made from chrome moly steel. These are available from Dove."
On this page: http://www.doveengineparts.com/documents/31.html So it sounds like there is a fuel pump drive (like a cam?) bolted to the gear on the front end of the cam shaft and maybe this came lose on your engine. Here's a photo: http://www.hotrod.com/webonly_january/photo_14.html If this puppy is running around lose inside the gear vault, I'd be concerned. Looks like it would be a pig to fix with the engine installed. _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
