Is it possible to remove EHA from fuel Dist?
Once you undo the electrical connector and remove the two screws holding the EHA to the dist (watch for the fuel spritz) you can pull it off. Make sure the two O-rings that seal the EHA to the dist aren’t lost. The face of the EHA that’s against the fuel dist, has a couple of holes in between the attachment screws’ holes.
Is it possible to adjust an EHA for an 87 260E?
My ’87 260E has always been a somewhat reluctant starter and needed to warm up for a minute before it would “take the throttle” with any enthusiasm. I attributed that to age & 200,000 plus miles. Something to live with. Replacing half a dozen rubber bits and a couple of hard vacuum line helped lots, but not completely.
Is it possible to adjust an EHA on a M103?
I stumbled across a paragraph on M103 drivability & the problems described fit me to a T. There is an adjustment to the electro-hydraulic actuator (EHA) that hangs off the back side of the fuel distributor. This is the gizmo that takes the commands from the ECU and adjusts the fuel distributor pressure. It’s the “muscle” for the ECU’s “brains”.
