Re: [MBZ] ring gear spun on f/w
No, discard both gear and flywheel -- likely the loose ring gear has worn enough spinning that it won't fit again. They aren't expensive. Crank, flywheel, and balancer are balanced "as a unit" on MB engines before the early 80's -- I've been told by a good source that later ones are balanced as parts (much better, to my thinking, but I wasn't in charge!), so you MUST match the flywheels. They often have an offset bolt and will only go on in one orientation unless you force the "out of place" bolt, check for that. Older 615 engines have a stamped line. Get a new pressure plate, too.

Re: [MBZ] ring gear spun on f/w
That would mean...If I use a used f/w the ring gear should be removed, and a new one installed after matching the balance of the old f/w. I spoz I could have them put the ring gear that was taken off the replacement, back on, its in good shape. thanks for the help Steve Message: 20 Date: Sat, 15 Jul 2006 18:54:41 -0400 From: John Ervine <[EMAIL PROTECTED]> Subject: Re: [MBZ] ring gear spun on f/w To: Mercedes Discussion List Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Van Cleve wrote: > BTW neither the original or replacement F/Ws have alignment marks (except mine) so > I'm just bolting it up and hopping for the best :-) If I remember my OM616 engine balancing info correctly, the flywheel is neutral balanced to the crank except during replacement - in that case, the new flywheel should be static balanced to the one coming off the car (and you make your own witness marks). -- John L.
