The fan clutch shouldn't have any effect on higher speed operation. If you're overheating at high speed I'd be looking at the condition of the fins, clogged tubes. If the radiator checks out, it's 6.2, you may be getting air in the cooling system through a crack somewhere or a bad head gasket.

If it's just a washer, if you can provide dimensions maybe someone can make some. How much are you willing to spend? $56 gets you a 6x6x1/8 Viton sheet. They'll last forever

The stock radiator was the best. You can't get those. I tried the aftermarket brass units, they're junk. Half the weight of stock and they pop randomly. I have an aftermarket aluminum/plastic unit and it's been fine but that's all I can say about it. There are some welded aluminum units out...

What grease are you using in the pilot bushing? Lithium grease are terrible for that application. A polyurea grease will do you better. The only polyurea grease I have found in the auto supply stores is Lucas X-Tra Heavy Duty (green). You should be using this grease everywhere else on your...

People walked across that desert without crankshaft pullies, transfer cases, Starlink, cell phones, etc earlier than the Donner party of 1846. It's still the cool season right now. We shall all agree that 79Vette is of a different cut than the rest of us.

I have had an alternator with bad diodes keep an engine running after the ignition is turned off.

That is quite possible. The HEUI system operates the same as the newer common rail systems. There is a minimum pressure required for a start. No dribbling allowed.

Those are standard plugs, there should be compatible with many brands. It's an IEC standard. I don't remember the number. They're often called reefer plugs as that's what refrigerated truck trailers use.

Cage failures are the result of lack of lube, possibly from breakdown of the lubricant. As I said, you'll probably see longer life from a bearing with a standard spec vs the special military spec.

I drilled out a CS130 alternator and installed plastic sleeves and Garolite washers to isolate the case. It works but I'm looking for a better method. As for the picture, you need to isolate the upper heatsink and add a stud that passes through the body of the alternator and it's also insulated.

Batteries will show full voltage until the are placed under load. Have you confirmed the batteries are in good condition?

Energy Suspension inserts are good. You need to make sure you get the right engine mounts. There are two options, 3.1116 and 3.1152. If I remember correctly you need to use the 3.1152. They both fit the clamshells but one insert is smaller which causes the engine to sit low in the mounts. Some...

It's $44 at McMaster-Carr. https://www.mcmaster.com/product/6661K126 The special grease call out is not necessary, detrimental even. A standard bearing with polyurea grease should easily make 40,000 hours. C3 clearance spec is standard for electric motors and generators.

The CS144 rectifier looks like this. There is no location for a stud on the negative side. That would need to be added.

If you're storing in closed containers look for VCI paper and oils. Volatile corrosion inhibitors do work well. They do need to be renewed periodically.

It isn't oxygen that causes seals to degrade. Different types of rubber have different shelf lives. Buna is 10 years. Viton is typically 25-indefinite. Humidity is the biggest enemy during storage. Proper storage is expensive. You can climate control the space or climate control the packaging...

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...
