My Pete rebuild

[ZeroNthedark]

Seems to be a real crap shoot with Cummins Remans. I had all 6 injectors done on my 870, so keeping my fingers crossed on those. Have bought all the actuators, but had to warranty 2- one because it was leaking out the "button" on front, and another that has a plug receptacle that didn't like anything being plugged in it. Nothing ever fit right, nor would it lock in place. More like a press fit.

Hope those injectors fix your issues. I still get a noticeable fuel smell from the exhaust every once and while, but am living with it for now.

Well, the engine is MUCH smoother now. Not sure if I should have plugged in the computer and reset anything? But the first hour or so it felt pretty sluggish - but then again I had a few 10% grades to contend with until I got rolling. One thing that amazed me is how it pulls smooth right down to 1100 rpm (I had to try it once just to see). Still has a little bit of a rolling vibration on a hard pull - when I get time, I want to pull apart the actuators and check them. The front metering has been changed out, but the back one still has the o-ring seals and I assume original? Hoping my fuel mileage comes back - the last 3 tanks have been dropping - but then again they've been heavy loads that had the wind drag of a hundred little parachutes...

I'd get my ass down to rawze or haggi for a good visual inspection. It might cost you a little but all that hard work and time/money you put in..... man we would hate to hear n see you blow a head gasket or worse.

Good luck! n safe travels friend.

Waiting for stars to align to do that. I made it as close a Macon, but I don't expect anyone to fit me in with no notice and I already had the next 2 loads booked anyway.

14k on it now, and I'm itching to use the 3rd stage jakes for the first time.

I only did one, and left the other one sitting on the parts counter. I just didn't like the looks of it. It has scoring around the end where it mates/seals in the cup and the bottom lands or rings has corrosion. Plus it had the older style keeper with the big tab and screw - who knows how many times it's been rebuilt, and the last guy at Cummins obviously didn't care about aesthetics, did he care about the important specs inside?

I pulled all of my actuators off to clean and inspect. No gunk in them, and the rear timing plunger was the only one showing a little wear @ .0055" side play. Ok, I figure since I picked up one of each, I'll go ahead and replace it. Start the truck and my rear bank is dead. Go figure, it's going back to Mexico. Cummins reman quality is right up there with A1 Cardone - you know you'll probably get junk, but there's no other options.

how did you determine the rear bank is dead? -- The ECU is well known for failing the rear bank and not firing it for 10 minutes + at a time + key-off+ key-on if you unplug it, or it losses connection for even just a moment.

I can't tell you how many mechanics that will unplug one of those solenoids and re-plug them back in to see if they are firing, only to accuse the rear bank (or sometimes one on the front bank too) solenoids of being bad on the engine. THIS IS THE WORST THING YOU CAN DO AND THE WORST WAY TO TROUBLESHOOT THE ACTUATORS THAT YOU CAN POSSIBLY DO -- YOU WILL ASSUME THERE IS ONE BAD EVERY SINGLE TIME!!!

it has been mentioned on this forum in the past for people accusing their (especially rear bank, as they do this the most) solenoids being bad and wasting money and effort chasing a ghost...

After installing all 3 of the actuators that I cleaned and tested, along with the "new" rear timing actuator, the truck started hard, and the thermal camera revealed that the rear exhaust manifold was cold. Shut it off and reinstalled the old actuator and the truck started easy, idled smoothly, and the exhaust manifold lit up in the camera.

I wasn't content with that alone, so I opened the "new" actuator and checked the plunger - .004" and it looked good. So I thought hey, maybe the plug was loose, or some other unknown, so I re-installed it to the same results. There was a distinctive tick from the fuel pump side - like a bent/bad valve on a gas engine, and the exhaust side sounded like an exhaust leak. With the engine still running, I unplugged the timing actuator and the sounds went away. Pluggin back in they came back. It wasn't the ecm shutting it off, the actuator was screwy.

never ever ever do this!.

you want to cut out an actuator,.. use insite and cut out cylinders (3 at a time).
