My injection pump is leaking fuel at the top around the nozzles. I have read posts regarding changing the o-rings on the nozzles. My 603 differs from the 5 cylinder with regards to removing the nozzles. Insted of a standard six point socket, it requires a splined socket to remove the nozzles. Most of yesterday was spent trying to locate the tool. The 3rd MB dealer I visted told me the nozzles were factory set and not to remove them. His estimate was based on shop removal of the entire injector pump, sending out for repair/rebuild, and re-installing the pump using required electronic timing adjustment equipment ($700-1200 pump rebuild, + 4 hrs r/r $$$). Oooouuch!

Just spoke with a trusted all MB non-dealer repair shop and was told I was looking at an hour or two to remove nozzles and replace orings (+/- $125 repair).

If it's just o-ring replacement, I think I can handle it.

ANY EXPERIENCE WITH THIS????

Where can I get the socket?
Anyone have the torque number for the nozzles?

thanks,
