100 miles from home... Back home, question.

iirc, nascar guys put a small pump & cooler on their axles...


If it's that big of a problem you may want to consider that...the pump runs off of a fan belt driven by the driveshaft or yoke


edit: apparently they have an internal pump now...

If you go Amsoil, you can order it from a dealer.
Check out this.

Since I have switched everything except my big genset over to it, I buy cases at a time.
My local dealer set me up for a discount.
I think its the preferred customer system now, but it was a while ago, and I don't pay any fees or have a minimum amount.

Don't know how it works now.

But I have pretty much standardized my vehicles, so I buy a couple of cases of 20W50 for my trucks and cars, a case of 0W30 for my lawn mower and other small engines, and 75W90 for my diffs and transfer cases and other gearboxes.


Even though they sell a limited slip additive, I have never needed it using the straight synthetic gear lube.

I wish I could put it in my turbocharged genset, it would really help the turbo, but it takes 6 gallons, and I just can't bring myself to buy that much synthetic diesel oil.

FWIW, since I seem to be hawking the stuff, this is the grease I use for pretty much everything.

BTW, I don't get anything for recommending Amsoil. Wish I did.....

They sell, or used to sell it, in a big squeeze tube like a giant tube of toothpaste.
I would buy some grease gun cartridges, then a case of the tubes for packing wheel bearings, and other general purpose use.

I would also buy a few tubes of the really thick stuff for slow moving heavy load uses like disk harrow sleeve bearings, but since my tractor is down, I have not used up what I have.
This, if I remember right.

Not useful for high speed or high temp stuff, but for low and slow extreme loading, it does well.

Now that I think about it, I may start using it in my tie rod ends........

That is a really interesting trick. I hate the fact that its blowing out now, even when it's been driven several times on the freeway without issue. My friend driving behind me saw smoke rather soon into this trip, maybe 20-30 miles of freeway driving. That's not good. By the time I noticed, it was much worse and about 70 miles later. And yes, the super thick diff cover was untouchable.

I'll take it back to the shop for them to check. If its bearings ok, but if its gearing I'm going to 5.13 and ditching the 4.88s. I only want a little more gearing. Either way, this sucks.

Keep in mind that "untouchable" is relative. Did it sizzle your skin?

I think that humans don't like touching things over about 120 and skin sizzles at somewhere around 150. Even poor grade dino blood oils are fine to operate near 200 continuously. A good synthetic is going to be fine operating in the upper end of the 200 degree range, 260+.

I am going to say you have a bit of an overfill situation and when it got to real normal operating temps it blew a cup or two out that looks like gallons when you paint it on.

I have run a 14b diff 535 miles straight in the dirt in Nevada in August with only a crane diff cover and amsoil. Those same bearings ran KOH this year. I don't think you have an over heating issue.

It was more like an upper radiator hose, after miles of freeway driving, AC on, dead of summer. Anything over a second and it would hurt.

Getting some Amsoil ordered up through a member Might even look into that high temp grease too. All I ever use (not that I've had a problem) is whatevers on the auto parts shelf.

For a crude temp measurement, water boils about 210F. Would you rather touch the diff cover for one second or stick your finger in boiling water for the same length of time? If your answer is the "diff cover", the temp is probably less than 200F.

When mine would spill over and hot like that, I would remove the fill plug and have a little lube spill out or it was right at the level. The oil expands a lot when it heats up. When it stops leaking, that's how I know the fill level is ok.

What weight oil should I run in the diff? Should I put the good stuff in front too, though I only run 4x4 at slow speed?

 

[bp71k5]

I think I run 75-140 Royal Purple. It on the parts store shelf.

My front diff still has standard lube in it, but I plan to change it to the same as the back to avoid carrying two different types on the trail.

 

[K85 Octane]

About what's the capacity for a 14/60? The covers aren't stock but I can start from there.

Thanks

Gallon in the 14b 3 ish qts in the 60

75/140 is a good oil to go with, heavier oil in axles really only helps to keep the film thickness up during high impact loading situations that we honestly don't see except in higher speed desert running.
