Diesel Engine Rocker Arms
« on: April 21, 2020, 19:59:42 »
Question for the "Selbstzünder' experts:

I got several boxes of new and used W113 parts which had some other model stuff mixed in.
There were rocker arms, which I could identify as for Diesel engines from the 60s to early 80s. 615 055 02 01 FEBI 7919
When I looked close to determine if they were new or used, I recognized that some had a brass bushing in the shaft seat, while others were just plain machined.
The diameter of the hole is the same. Does anybody know whether the brass bushing parts have been re-sleeved or are they just a different generation?
If what I say is not clear enough, I can take some pictures.

Not the same part but early 190SL rocker arms had bushings in then so my opinion is maybe.

From what I remember the non bushed rocker arms replaced the ones with bushings in them because the ones with bushings in them wore prematurely.

At some point Mercedes changed to a harder material for manufacturing rocker arms and camshafts on those diesel engines. Maybe the bushings were deleted at that time.

That would be an explanation. Seems they are the same parts, just a generation apart.
Thanks, guys!
