Another installment on Gale Banks diff cover test

[Wild one]

 

[Burla]

Those are great video's, we also discuss this in syn thread for guys wanting to know more, H395 has been working on this issue a bit. Bottom line, it really looks like stock diff covers are a perfect design, and these after market ones have some issues. Air is the enemy of gear fluid, and the benefit you get from more fluid doesn't make up for the air that design adds to the fluid, not to mention the fluid misses parts of the gear set. Must watch tv, good post wild.

I can just about guarantee Banks will come out with one that is a game changer. He isnt doing all this research for fun.

Likely true, but if you think about it I think it will be quite hard to do. Even if it isn't square, it likely wont be a perfect route to the gear as stock. I'm really glad someone with banks street cred took this up and glad to the guys who found this info and brought it forward to RF. Needless to say regardless, I wont be getting an aftermarket diff cover and that was on my list. I'm just sticking with ester based redline gear fluid for my upgrade.

It wouldn't be hard to duplicate the channel that's in the factory covers into a new cover,you could even retrofit a tin channel into most existing covers . I agree with Joes 1500,i think Gales up to something,and it won't be long before he comes out with a cover that incorporates a lot of the original covers designs into a finned aluminium cover.

Funny how he brings last test up to 50 mph to show more aeration and only 30 mph on previous.


Like how this guy thinks.....

If anything, they're obviously going to release a cover that has internal fins and a round back..so as to channel the fluid up the internal channel, around the gear, and forward..without sending as much outward. Okay...

This test doesn't really tell you much of anything, though..it's assuming that front isn't receiving adequate oil transfer..but how can you tell by looking at a back side view? You don't actually know how much oil is moving forward from this angle.

Then let's talk about what is actually pushing the oil forward. It's not the channel, it's the gear. The gear movement is shooting oil out into the front. This is happening regardless of what is happening on the back side. Gear spins, oil goes on groves, oil shoots forward. Again, no evidence of this not happening.

Then let's talk about it hitting the back, channeling up, then falling back onto the gear. Let's talk about heat transfer and surface area. Why exactly wouldn't you want the fluid to contact as much of that back, finned, surface area, to dissipate heat? Isn't that the entire concept of a heat sink? Do you think having the oil with less surface area on the cooling heat sink will not cool better? Lol. If you have two identical cups of hot coffee, keep one in the cup, and pour the other in a large shallow pan, which do you think will get cold first? The coffee in the pan..more surface area to dissipate heat.

Going back to oil bouncing off the top..gravity still brings it back down..onto the gear..that is flinging it forward, no? That oil is still having more surface contact with the cooling surface of the cover, still a larger surface area to cool..

Then he's talking about airation when there's air in there. I'm no scientist, but, isn't that inevitable? Unless you fill the entire diff up, removing all air?

The fill level in relation to the gear matters. The deeper the gear is in, the more drag there is..but if you've got a bigger pan, and it holds more fluid, but the gear isn't deeper..It's going to stay cooler with equal drag..cuz again, there's more substance to heat, more substance to dissipate heat, with no additional drag.

I'm no scientist..but I'm not buying this **** until there's real data to support his THEORY. He's got no eye into seeing if the **** is getting adequate lube, more importantly (why would you do a test like this at all) with no temperature of the gears (which might be hard, but not really..drill a hole, tap, plug, infrared test gear temp) ..but ****, he doesn't even have a fluid temp gauge, to see what's happening with the fluid.

No scientist here..but this **** is missing just about everything necessary to start proving his theory..right now it sounds like marketing and guessing..while providing people a yeeyee clear diff cover (clear radiator hoses, anyone? Lol.)

But from what he is pointing out - not sure one is even needed?! Seems to be proving the stock diff cover is doing the job it was designed for and doing it well. I mean more fluid would make it cooler I guess if done right.. but with the more space between the cover and gear ring - I'd think more agitation you'd have..

My guess is it will be shaped similar to the factory one on the inside but the outside will be built more for a cooling effect rather than increased capacity.

Banks ia all about advertising and being a salesman and thats what all these videos are about. They will come out with there own covers and I have said that from the first vid he put out.
How many rearends have burnt up because of overheating from a lack of lubrication from the aftermarket rear covers that hold more fluid and have better cooling.

I know after seeing pictures of the inside of my Mag-Hytec that its not square inside like Gale implys it is.

Actually mag tech just recently within the last couple years has slowly been changing their design to the newer style, which I assume you must have. Up untill then they were all pretty much identical to the one in the video.

As for how many have failed because of it , that is an unknown. But you could also ask how many have failed because of the stock one ? I guarantee there are more trucks out there with way more miles on them that dont have a aftermarket cover then ones that do.


One thing to learn about banks' video is this. Just because an aftermarket company makes it, stands by it, charges alot for it, doesn't mean it is doing you anygood.

.

So you have proof of this guarantee on these trucks ? There are numbers showing this somewhere ?

Untill I see proof that this cover I have is not doing a good job I am not just going to by what Mr Banks is saying like its the bible.
Having 2 quarts of extra fluid a cover that will run at cooler temps and is easy to fill and drain makes it a plus to me.
To be clear I am mainly talking about my 1500 and the fact it only holds alittle over 2 quarts stock, I think the cover is more beneficial in my application then lets say a 2500 that already holds 4 quarts of fluid.

My opinion is my cover is better than the factory cover I have yet to see proof otherwise, now the one the Banks comes out with might be better than mine but that only makes good business since I mean see a cover and just dont copy it improve on it.

Yes actually I have a relative that owns a very profitable hot shot company. He runs bone stock trucks. Whatever brand, options the long term drivers he has want. They run them for 300k then get rid of them, no matter what.

Like I said , bone stock. Oil changes and all maintenance done at dealerships. No special high dollar oil or filters. No fancy diff covers or aftermarket fuel pumps/filters. Bone stock. And will have atleast an empty 40ft 40k gooseneck hooked to it 95% of the time.

Another example. I work in the oilfield. Our trucks run 14hrs a day every day. I see the same guys with the same trucks every day . There is usually around 20 on location, doing anything from just hauling people to pulling 30k plus.They are lucky to get the oil changed every 15k, and that will be with the cheapest fastest roadside oil change place you can find. Again no fancy anything . We abuse the ever living hell out of these trucks. Pulling trailers, Me personally, I pull 32k 4-5 times a week with my company truck. It is an 18 3500 crew cab 4x4 Chevy duramax. It has just over 35k miles. I picked it up at the dealership with under 100 miles on it.

So yes I can safely say that unless the wear and tear on the rear end happens all of a sudden after around 300k miles and you plan on keeping it that long, you are in fact wasting your money.

Hell the diesels come with 100k mile powertrain warranty. I would think they would put those fancy covers on from the factory if the stock one was as bad as some people think it is, just to make sure it made it to warranty.

The first mag hytec I remember seeing was about 25 years ago. Dont know when they actually started making them but that is about when I remember seeing one. And I remember thinking then. How did all those trucks that were built up until then manage to survive for the 100's of thousands of miles people put on them without one of these. And that was before all the fancy high dollar synthetic oils were mainstream also.

But that is the beauty of this world. At the end of the day it is your truck, your money , you do what you want. But as for me, there are enough trucks out there with way more miles on them running the stock cover, than I'm ever going to put on mine before I trade it. So I feel 100% confident that I dont need to spend money on a fancy diff cover.

I believe you are talking 2500s and up and I am talking about 1500s with less fliud capacity.
I was really joking about the number of trucks onnthe road I am surr you are right as most just leave trucks stock. But you did say guarantee ot.

Never even thought about putting a cover on my 2500, but this 1500 has a small diff and I wanted something to help keep it cool.
