Helping JimT out with an inframe ...

[JimT]

Ok, sorry I've been a bit quiet the last few days.

Corrections: code 559 low rail pressure first appeared in Dec. of 2018, about 6 months after I got the truck. Roughly 440,000-450,000 mi. Shops I consulted dismissed it and it wasn't until my own searches led me here in June of 2019 that I found and repaired the pump head. At that point 3/4 of one ceramic plunger was gone. My speculations is that big fleet long oil drain intervals and EGR/DPF issues led to the first cam being wiped out somewhere around 1st/2nd owner. 2nd owner had it less then a year before I bought it from a small dealer.

As far as the cam goes, only one lobe is damaged, the rest looks ok. I'm speculating that it was from the fuel pump, but at this point it's only a guess. Waterloo's cam was a slightly different part number, his last digit was 6, mine was 9. Probably the change from narrow lobes to wider lobes? Another reason I think the cam might have been replaced once before.

Rawze was off with the date slightly, the 12th I took the morning to square away the monthly finances and paperwork, then we had some strong T-Storms roll through in the afternoon. We didn't see much rain here but Mr. Hagg had some good sized hail. Finally pulled the head off first thing Wednesday the 13th. Dropped it off at Mr. Haggs and came back and pulled piston and liner #2. Worked late yesterday breaking all the bolts loose on the rest of the pistons and prepping them for removal before more T-Storms rolled through.

Another trip to Mr. Haggs this morning (the 14th) to order parts. Came back and pulled the rest of the pistons. Another rain shower rolled through while I was working. Going back out to disassemble the wrist pins and work on the liners next.

-------------------------------------

I'm not the expert here, but from things Rawze has said the head still looked in good shape. But the piston heads had plenty of buildup, rings were worn and liners were shot. I don't see any major visible damage, most likely years of carbon buildup, fleet maintenance and bad driving habits(?). Don't appear to have any dropped liners (wasn't consuming coolant). Otherwise, I'll let the pictures speak for themelves...

Too many pictures to keep posting them all here. So here's a gallery everyone can check out:

I'll add more there as time goes on.

Many photo's have a comment in the bottom left corner identifying which position they are from. Some photo's are for reference during reassembly and some are just to show my wife :)

I'll post a parts and price list once I get everything, but I'm just shy of $20k in parts so far. Of course, make sure you get the correct parts for YOUR engine.
