95 e300d injection pump mounted shut off valve swap out question - PeachParts Mercedes-Benz Forum

I've read several threads and watched videos on how to do this. Some say they can swap it out in about 5 minutes after it's exposed.

The video shows an external shutoff arm that is raised to bring the internal slot high enough to hook the new shutoff valve into it.

Question: For the pumps that don't have an external arm what procedure is used to hook the new valve into the proper place?

A little concerned because some have mentioned the rpms can be excessive and no quick way to shut off if not installed properly.

Don't the 606's use a solenoid for shutoff rather than the mechanical lever of the 603? If so, it's a different animal.

The 606.912 with throttle by wire has solenoid fuel cut. The 606.910 with throttle cable is like the 603. There’s no stop lever because you couldn’t get to it with the intake manifold in the way. Backup fuel cut is at the big oil filter. Even with no stop lever the shaft for a stop lever is there on a 606.910 IP. You should be able to turn the shaft CW with pliers.

I think you meant "at the big fuel filter that looks like a spin-on oil filter".

That is how one shuts down the fuel flow to the engine.

However, in this case, I'd use the suction from my mouth to test the new vacuum shut valve, try the valve out of the car first and then install, test by mouth and see if the "feel" has changed (it should).

Interesting, learn something new every day. That '95 W124 300D is sure an oddball
