I am looking at doing this to truck. Which ones are the time and fuel actuators? when disassembly is it just the 2 bolts that hold them together? Is there a rebuild kit available for the internal parts?
my motor is 871.

Metering are the outside 2, timing are the inside 2.

You are correct - 2 bolts on the back side of each and they can be seperated.

There is not a rebuild kit or parts for them that I know.

Thank you.
After rereading the Technical Directive I might be better off replacing with new ones. I'm double past the mileage that they were out. I would still like to take them off and check this out. Maybe i can build one out the 4 four just to have a spare?

They are exchange parts and fairly pricey. I would at least try to check them out, clean them up and rotate the plungers. See if anything improves.

I will clean them up then. Nothing is really going on. Truck is not running rough, just losing MPG. Looking on here just to find a starting point on where to find it. I haven't replaced or cleaned these since I bought the at 280k miles, the truck has 1.1M on it now. I have dropped 8.3 avg to 8.0 avg.

In the pictures with the dial indicator, where did you get the clamp that is holding it?

[Chamberpains]

I just got quoted $590 per actuator. Holy beejebus they went up in price. I bought four 4 years ago at $460 per....
