Ref post 12 in this thread just to reiterate what was previously mentioned. Very cheap insurance to change those critical components. You already have it apart, now replace the mentioned components before reinstalling.
----- Yes, compared to many others, you have dodged a bullet indeed ------

Or just barrels and plungers ? Thx
You need to go play the lottery.... you have gotten VERY VERY lucky .. that pump head was built before may of 2013... it is that old.
REPLACE the tappets, plungers, and barrels/rollers ... a set of all 3 ... I.E.> all the guts above the pump crankshaft.
By taking it apart, you just saved your engine's life... and if one of the plungers is not moving freely ... then it was right on that very edge of cracking, flaking, etc.. and destroying the entire engine.
I am replacing part now, it looks like 1 tappet goes deeper than the other .both of them are locked on the pin so when i try to put back head pump with barrels and spring back to the pump it doesn't go all the way throughout because barrel and spring in the right side touch the tappet first before the left side barrels witch make a gap between the head pump assembly and the pump do i can just keep tightin bolts i am afraid to break the bolts t have attachedpictures showing what i have done

2013 cascadia 2250 . Yesterday i noticed something weird going on
truck shut off twice when parked . I was outside the truck i didn't know the reason for that. So while driving engine shut off and turns back on in the middle of the hwy at night it was scary. All the lights on dashboard goes out and came right back on. No engine light what so ever. i search on YouTube they said its power module the call it PNDB. Or the power switch. I happens 5 times on the road after driving about 300 miles amber light came on with spn 157 fail18. I serach it again on line it has some thing to do with fuel pressure rail. It's true that truck it has less power than normal .i was loaded with 36k lbs on it. So my question is does electrical problem could cause fuel pressure failure . Thx alot
I just had the same issue with a 2016 cascadia and it was the PNDB MODULE. It costs about 380 and easy to swap out.

Seems to be a common occurrence with the Cascadias (maybe Freightliner in general). What was the mileage on the most recent one you replaced?

For you Freightliner guys that may not know this. Freightliner, actually DTNA will provide service info free to the owner of the truck. If you bought the truck used it will need to be registered into their system A Freightliner dealer can do that. If they will. Talk to somebody in their warranty dept. If the dealer won't do it it can be done as part of the process.
The process is a PIA and can take a few weeks. So do this BEFORE you have a problem. Once in you have access to just about everything including wiring info. I have set up 3 customers so far. They allow two emails on the account. Here is the link to get started.
