Re: Replacing fusible link with a breaker

It will be helpful if you have a clamp on current meter to see how much current is causing the voltage drop. This was I think at 50-60 Amps across the link. This was back in October. Can't remember the exact numbers. Most of the drop is in the fusible link. I had some smaller drops at other points....

Re: Replacing fusible link with a breaker

Thanks for those numbers, Paul. These are things I definitely like to see. I discovered this problem by accident when I was trying to find the source of a rapid voltage fluctuation when the system was charging, hence the scope in the picture, but when poking around with my meter I came across that n...

Replacing fusible link with a breaker

I'm experiencing quite a bit of voltage drop in the fusible link to the pos terminal from the alternator. I'm sure the subject has been approached here about just putting an inline fuse. But I am thinking of putting in an automotive circuit breaker. They behave much more like a slow blowing fuse or ...

Re: 1987 Spacecab - diesel fuel tank questions

You could get under the truck, compare the length and where it needs to go around the frame rails. I can't think of a reason. Having no drain plug really shouldn't be an issue. If you are super worried about it you could always just get a separate clear sedimenter bowl/water separator that holds a g...

Re: 1987 Spacecab - diesel fuel tank questions

The gas and diesel tanks have the same number of inlets and outlets. I've never heard of someone swapping the tanks when they do a conversion. I won't speak as to the Space Cab and Shortbed tank sizes. I am having a hard time interpreting my parts catalog. Isuzu did not make this very easy to unders...

Re: Body Mount Bushings for 81 Luv

It's pretty much going to be a generic part that is very cross compatible. It's essentially just a piece of plastic or stiff rubber to help isolate vibration.

I've heard of hockey picks for body lifts since they're quite substantial. A body bushing is maybe a 1/2 inch thick if even that.

Re: Raspy Scratching Noise Periodically on Acceleration

that GL-5 additives will eat brass Luckily I am not aware of any brass in any rear ends to my knowledge, and luckily you aren't putting it in the transmission. I believe it is the phosphorous in the GL5 oils that stick to yellow metals and every time you shift it's like sand paper at the molecular ...

Re: Raspy Scratching Noise Periodically on Acceleration

The GL rating is essentially the rating that tells you how well it resists from being squeezed out from surfaces under pressure. Whatever you run nowadays will be Superior to what they used to use for the most part. GL4 won't hurt. Especially if you just putter around with it. Sounds like you're pre...

Re: 1987 2.23 liter diesel engine motor mounts

Roy. It appears maybe I'm just a fan of removing things and making sure I have ample room. It ends up being far less frustrating. On the driver's side you can get to it without removing anything it looks like. The passenger side you'll need to remove the lines. Just make sure you clean before taking...

Re: 1987 2.23 liter diesel engine motor mounts

I'm just wanting to make sure. Without pictures and a thorough description I can only imagine. And having worked as a mechanic when drivers come up to me and describe something and I go look, 90% of the time it's normal wear or perfectly fine. Really a floor jack with a block of wood is all you need...

Re: 1987 2.23 liter diesel engine motor mounts

Yes I am familiar with Richard Feynman's demo. He's actually a really neat guy, I have a couple of his books, definitely not as humble as he lead on to be! :lol: Honestly over time it stands to reason the engine will lean towards the passenger side as the engine is always being pushed that way. When...

Re: 1987 2.23 liter diesel engine motor mounts

I don't know that I've ever heard of the mounts in these going bad except for just flattening and hardening over the years. These motors don't really put a lot of stress on them. Are you getting any weird symptoms like excess vibration or driveline shock?

You could leave everything in place but it makes for a more miserable process... Really to do it by the book (I guess the way I described?) Is the best way unless you've done it several times and know how to beat flat rate...

Re: 1987 2.23 liter diesel engine motor mounts

Roy, It is a pretty simple procedure. Just takes some patience, these trucks tend to be easier to work on if you are tiny and have tiny hands. Not so great for me! So!
