The CS144 appears to be a candidate that can be isolated as well. If you ask grok about it, it kind of hints that the CUCV II may have had custom CS144s.

I'm looking at pictures to remind myself of why I decided the CS130 cannot be isolated. It's because the poles in the rectifier are stacked on top of each other. With the AD244, the poles are side by side. The mounting screws of both poles are isolated. If you got a second insulator shim and put...

Sandia National Labs did a very interesting study on failures of Electro Motive engines used as backup generators at nuclear plants. Everything was good until the early 1990's and then they started seeing silver in the oil. EMD engines use silver faced bearings. EMD engines don't have a drilled...

I isolated the alternator body from the bracket. I did not isolate the stud. Don't drop a wrench on it! I used Plasti-dip as a bit of a safety but it's not thick or durable. I may re-apply something thicker. I think I decided the way the rectifier installs made it impossible to isolate. I forgot...

The driver's side alt is unmodified. I made no modifications to the CUCV wiring harness. As a prefice, I generally source materials from McMaster-Carr as I use them daily in my normal job. I drilled out the passenger side alternator and sleeved it with some nylon air brake tubing. I used...

It was the latter set, I think 1996+. The specific truck it came from was a 2001 C3500 with a single alternator mounts on passenger side. There is an additional bracket necessary for the second alternator, these guys are making a reproduction of it. The setup also supports A/C. The serpentine...

Ospho turns the 1980's vintage CARC turquoise. Phosphoric acid etches polyurethane paint in general. I have my tugboat fleet using citric acid instead. It's a better daily cleaner. It doesn't have the rust conversion properties phosphoric has. Use Ospho between coats and citric for your regular...

Very interested. I put a dual alternator serpentine setup from a 2001 C3500 in my M1008 CUCV. I used standard CS130 alternators and sleeved the mounting holes to isolate one. Not ideal but it works. There are pigtail adapters so you don't have to cut your stock harness and the gen lights will...

During oil starvation the mains fail first. The rods are fed from the mains but the cross drilling works as a centrifugal pump to keep the rods fed while starving the mains.

I've seen that hose material before. It will be hard and full of cracks within 10k mi. Look at the lettering on the hose. If you see NBR, that's nitrile rubber and it doesn't tolerate the heat associated with injector return lines.

That indicates water in the fuel. The old Detroit Diesel or Electromotive trick was to use methanol to free up stuck pumps. Of course these were unit injectors.

Sandia National Labs did some examination of failed Stanadyne DB2 pumps after the army switched from diesel to JP8. They found that none of the failures were due to lack of lubrication. In my more modern fleet, the only wear-out failures were on Denso ECD-U2 pumps which occurred at 18,000...

I did a lock cylinder in my 1976 truck some years back. There is a thin spot in the column casting that you hammer a screwdriver through to get access to push the spring loaded retaining pin.

SAE o-ring boss plugs are always difficult to break loose. What brand of wrench were you using? There is huge variability in hex key quality/performance.

Roosamaster became Stanadyne. Very common pumps. It's not cost effective to rebuild a seized pump with new parts. Generally the pumps all have similar internals with different housings between models. If you can't find an identical housing you may find compatible internals.
