Fuel Grade For Older B7100D?

[etmccaus]

Hi, all --

Forgive the simple question as I'm just a newbie. Bought a one-owner, early (think it's a '78-'80) B7100D along with a B219 loader. Always garaged indoors, runs/ starts well, just needs a few little things -- replacing spring pins in the front 4WD driveshaft yoke to regain my front driven axle seems to be the biggest item on my docket (anyone know how bad a job that is?).

Anyways, I'm new to the diesel world, so I need your input on what fuel to feed this little monster. I know it's calling for #2, but it seems many of the diesel pumps out this way are all serving ULSD. Is ULSD safe to run in something this old? Do I need to look for something else? Is there an additive I'd need to run ULSD?

Excited to put this to work, but I want to top off the tank before I do -- the bleeding process doesn't look like something I want to do right away in 5-degree weather...

Thanks for your help!

The old B will burn just about anything you feed it!
I run off road, Either #1 or #2 depending on the time of year, and I add a little Stanadyne to keep everything flowing well.

All diesel has switched to USDL (Ultra Low Sulfur), it's just like when they dropped Regular leaded gasoline.

Yep good to go with ULSD. Its supposed to clean up emissions so the diesels don't stink so bad when they fart...

All those joints are splined, all the pin does is keep the yoke/drive shaft in place.
If you have lost your 4wd you have lost the splines. You'll need parts and pins.

Like it was said, all you have available is ULSD, and it will run fine. Same with the cetane rating- it is a non-turbo, low tech, low output diesel, and will run fine on 40 and above. I run both 40 and 48 in mine, and see no difference whatsoever (just depends on the station where I get diesel). I run some Powerservice to keep it from gelling and to add some lubrication for the pump (there are lots of opinions on whether you should run additive, what to use, etc.- you will have to decide for yourself because there is no definitive. Lots of experiences and stories for all camps, but no final answer).

Well, thanks for clearing that up. Now I'm not too afraid I'll be pouring the wrong stuff into the tank...

On to the 4WD. Little scared about the splines...hope it's not the trans or front diff shafts that are stripped...

This is what your parts should look like.

Man it is such a pleasure too see spotlessly clean parts waiting for reassembly.

Thanks. Hoping I still have good splines on the diff and trans shafts. Where to the splines usually fail? (cringes)
