I have a "Big Blue" whole house water filter. The first time I went to change the O ring it looked slightly oversized. Just like you it was a matter of working it around carefully into the groove. This video was very informative. Thanks
Make sure you use the silicone grease on those or they jam up. Had to put a cheater on my handle to get one undone to clean the filter. After the previous person didn't use enough.

I build RVs here in Elkhart. It’s the same principle as a weather seal. You don’t want it short or tight because when it’s cold it would be short or stretched. So we cut it long and compress it into the channel that allows it to slide and settle. I was doing whatever I needed to do to make it look good and then I was taught the proper theory and technique needed to do it right. Everyone saying you stretched it either hasn’t learned the lesson about shrinkage or has a mental shortcoming. If I kept stretching it to fit and crimping it into place, then when it is sent to a freezing place it will shrink so much it could pull away and leave a gap at the corner.
Thanks. Humanity is interesting when it comes out on the internet. I've seen this with my RV, what you're saying with the weather trim being too short or long. I was replying to every single message on this and stopped except for the worthy ones.
Yeah, some can be difficult. I find that actually pushing the material together, bunching it up so to speak, will adjust its overall length. It also adds thickness.
Thx Jeremy. This cover is on my to buy list. You just might have saved me a call to Banks. Thanks for demonstrating this real time w/o any editing tricks.
A lot of auto parts stores sell an o-ring splice / joining kit. If compressing it still leaves it to long you cut it on a slant, not straight across and measuring carefully, cut out the extra with the EXACT same slant and glue them together. Put the splice at the top. I've used this on automotive, marine and authorized aircraft repair, it's an approved method for oil sumps and covers (not pressurized)
3m makes an excellent "flexible crazy glue" but a bottle is around 40$. Still worth it for other rubber goods. The kits are a piece of O ring and some crazy glue,and the glue always dries up first 😂

Anyone who works in the vacuum chamber for semi conductors can show you how to do this easy. Make sure you use a silicon grease, bead it in but make sure to create little humps along the way. These humps are then pushed down with one finger once the whole o ring is snug. Also everyone knows your asking for a leak if you cut it.
Large o ring'd gaskets even some valve cover gaskets you have to push them back into themselves or you end up stretching them, ending up with what looks like a too big of gasket.
If you ever have an o-ring that actually is too big, on an application where that O-ring doesn’t have to stretch around anything, where it’s being used in the same fashion as your diff cover, you can actually cut them and crazy glue the ends back together. It’s a step that is used only when there is no other option though.
3m makes a wicked flexible crazy glue for rubber, and it works great for doing this if needed. Thing is ,you get what you pay for and it's not cheap the last bottle I got about 5yrs ago was 35$ for a normal sized crazy glue bottle.
If I needed one, this would be the only one to buy. But if it ain’t broke don’t fix it. If you don’t have a hot rear end, don’t swap out the factory cover. It was engineered for that vehicle.
Thanks for this-it’s Saturday and can’t call Banks, so I think I’m stuck with diff cover off. Why doesn’t Banks tell you this may happen, they sure thought of everything else. Again Thanks!!!
Yep you should think of an o-ring like a rubber band if you stretch a rubber band what happens its diameter gets smaller so of course when applying an o-ring same thing you want a good thick diameter for maximum contact to the two mating surfaces it also allows for shrinkage to not be an issue as well from the heat
I was able to get mine in but had to hold in in place and it would stay for a few seconds then pop up, I ended up having to hold it in place and put the cover on quickly to keep it in place
The drop is super glue with glue that flooring together and you'll never have a problem with it cuz super glue was originally designed for the gas company for them to make o-rings in the field
Either reposition and re set it, buy another seal OR cut and superglue the seam. That works just fine for my MK4 VW TDI Jetta coolant flange now for thousands of miles. Zero leaks.
You know if you use a touch of dielectric grease to lube the rubber.. it kinda finds a happy place.. and prevents it from sticking or drying out over time. Or stretching as you install it.
@@JeremyPrattigmp2uok gear oil then. Something that’s compatible with the nitrile rubber o allow it to relax with minimum friction into the grove and even the tension across. Banks says gear oil because it would be assumed that doing this job you would obviously have gear oil. But my cart has that grease and the hose reel is across the shop. And I don’t need it hanging around my feet until I’m ready to fill the diff. 🤷♂️
Basically you probably maybe stretched the o- ring put it on put it on. And basically you can cut it anyway I will glue the cover on with ultrablock with the the o-ring and remember folks silicone sealant are not to be used with gaskets.
Without even watching the video. I could tell that the installation was done incorrectly with any rubber gasket it needs to be pushed down in multiple positions before inlaying the entire gasket to ensure proper positioning even the instructions that you are given for incorrect the instruction should have been to Overlay the gasket to the groove pushdown in 3 6 9 12 0clock and repeat in between all four positions till the gasket is inserted
I wouldn’t have any problem cutting the o ring, we’ve be making orings in the maritime industry for decades without any issues. Just put the join at the top of the cover.
I had the same problem installing a new valve cover gasket on my Chevrolet LS engine. It wasn’t obvious I had made a mistake until it leaked a few drops on the header! SMH

I was like nah, i'm not that interesting for people to watch.
No, you got carb cleaner on it. Either from spraying down, or leaving some in the groove. Alcohol in cleaner causes them to stretch. Did it to carb bowl on my Honda, and had to wait for replacement.
Thank you very much sir because I was just putting mine together and I had the same thing and I said oh shit I just saw a video let me go watch it and see what he says.
Didn't watch the video and came here to comment....this isn't covered in the instructions and it took multiple people at Bank's to figure out how to approach this.
they sent you the correct ones. But the issue you stretched the gasket a little and caused excess at the end. If you laid them down w/o stretching will be the correct length.
I changed mine because I tow a 17k pound 5th wheel and want my diff to stay cool. The other reason was to gain visibility to the fluid level and condition and make changes easier because this has a drain plug vs stock requires removing the entire housing. Banks has some good videos on factory vs other covers and their cover.
Because they dont realize that it just takes a little bit longer for the oil to heat up to the exact same temp. A cover has no heat exchanger lol and more fluid just takes longer to heat up. But wow do a lot of people fall for it and not even question it. Oh plus gotta fit in with the crowd
@@docksidemarine4273 This cover doesn't add any fluid to the rear end and has a lot more surface area for heat exchange.l including scoops. This is the only cover to do so.
Sorry you installed it wrong. You are supposed to do it almost like star pattern on lug bolt to minimize stretching that naturally happen if you insert it like a tire on rim going from point along the length you are supposed to push in star pattern.
When I got mine it was just a link to a video which went from install gasket to gasket done but didn't show the install. I understand it's been updated.
NOPE!!! Tuck in gasket in four spots around cover, continue to go around tucking in gasket in middle of two previous tucks until all of gasket is tucked in.
Installation method was wrong…there is a right way and a wrong way to install these types of gaskets! I installed one of these diff covers on my son’s truck with NO issues.
First problem is your running a Dodge... that being said, just silicone it on... even Dodges don't blow up the rear end enough to need an o ring seal on the cover.
Your push forward as your pushing. You are causing it to stretch. There is nothing wrong with the part it the installer that is improperly inserting it. Common mistake of o-ring installs.
Ya not uncommon , by the time it's tugged around the perimeter they tend to grow a little. You may have to retrace (compress) a little to get slack out.
They didn't send you the wrong anything you just have 0 mechanic knowledge and or experience lol gale banks is the GOAT of diesel pickup truck technology dont doubt him ever!!!

@@formulized94 As for RUclips, just send it and see how it goes. Some people like your content, others don't, others give you a ton of problems and some love it. Don't spend a ton of money of getting your channel to take off, one guy reached out and said for 75k he'd have me at the top of the list and making bank. I was like nah, i'm not that interesting for people to watch.
No point in even going for an aftermarket diff cover in the first place honestly unless you got a diff gauge saying to hot.
Also use rtv on the outer half of the lip
No, you got carb cleaner on it. Either from spraying down, or leaving some in the groove. Alcohol in cleaner causes them to stretch. Did it to carb bowl on my Honda, and had to wait for replacement.
No, If you watched the video this is how they come from Banks.
@@JeremyPrattigmp2u ok, no it is. Thanks for update on how Orings work.
I just wish they'd offer a cover for a Dana 70HD...
Send them an email, i'm sure if they get enough to warrant the machining cost they'll do it.
Thank you very much sir because I was just putting mine together and I had the same thing and I said oh shit I just saw a video let me go watch it and see what he says.
You're welcome. Glad this could help :)
Everybody figured out what you were doing once you said push back... didn't need such a long vid
Called the shop just to be told READ THE INSTRUCTIONS 😂
Didn't watch the video and came here to comment....this isn't covered in the instructions and it took multiple people at Bank's to figure out how to approach this.
You just saved me some frustration
You stretch it out ... thay fit perfectly fine .
It's called compressing as you install
they sent you the correct ones. But the issue you stretched the gasket a little and caused excess at the end. If you laid them down w/o stretching will be the correct length.
This is how they come, intentionally long per engineering.
No its not long. I went one more lap and by the time I finished the second lap is was corrected.
take your time. It works great.
just like installing gasketing wen i used 2 fix windows & screens in my paint store... 😁
Helpful trick man.
Nice job god bless
Your problem? YOU BOUGHT A DODGE!!🤣🤣🤣🤣🤣
You have it stretched.
If you watched the video I explain why it's the way it is.
Dumb question, why do people even change the factory diff housing anyway?
I changed mine because I tow a 17k pound 5th wheel and want my diff to stay cool. The other reason was to gain visibility to the fluid level and condition and make changes easier because this has a drain plug vs stock requires removing the entire housing.
Banks has some good videos on factory vs other covers and their cover.
@@JeremyPrattigmp2u ah , that makes sense.
Did you do temp checks before and after change? If so what were results.
Because they dont realize that it just takes a little bit longer for the oil to heat up to the exact same temp. A cover has no heat exchanger lol and more fluid just takes longer to heat up. But wow do a lot of people fall for it and not even question it. Oh plus gotta fit in with the crowd
@@docksidemarine4273 This cover doesn't add any fluid to the rear end and has a lot more surface area for heat exchange.l including scoops. This is the only cover to do so.
Sorry you installed it wrong. You are supposed to do it almost like star pattern on lug bolt to minimize stretching that naturally happen if you insert it like a tire on rim going from point along the length you are supposed to push in star pattern.
It's not too long, you stretched it. Push it hard the opposite way so it expands, then it will seal right
You didn't watch the entire video.....
@Ripkuno101 no, I don't think so.
@Ripkuno101 I watched it all, it was hard though, glad you figured it out.
And the differential cover needs this?
Yes, it's full of oil that is being sprayed around while driving so 100% seal is necessary
@@JeremyPrattigmp2u all these years..............now I'm in the know.
Nah, it's the right one, you just have to be careful to not stretch it at all when putting it in.
Is there a manual and does it say this?
When I got mine it was just a link to a video which went from install gasket to gasket done but didn't show the install. I understand it's been updated.
NOPE!!! Tuck in gasket in four spots around cover, continue to go around tucking in gasket in middle of two previous tucks until all of gasket is tucked in.
The video covers the procedure that I was told on the phone with Banks support.
A little red gasket maker on that cut and no leak
Installation method was wrong…there is a right way and a wrong way to install these types of gaskets! I installed one of these diff covers on my son’s truck with NO issues.
Now I know, and lots of others too. Even Banks support learned as it took multiple people to finally tell me how to do this.
Painful watching ol’ sausage fingers exercising their dexterity , but good lesson for the unwary.
Thanks 4 your passion.
Rocket science 😂
Why did you need a new cover??
I tow heavy both flat and mountainous, bought into the cooling aspect of this cover. I also like the looking glass and fill/drain ports.
THANK YOU JESUS !
Should of just kept the stock diff cover and no video no problem
First problem is your running a Dodge... that being said, just silicone it on... even Dodges don't blow up the rear end enough to need an o ring seal on the cover.
That’s good to know
Using a bit of nouse as we say in Australia
Just got to know how to install a gasket
It's only a diff cover, rip the stupid O ring out and fill it with a good quality RTV sealant. It'll last much longer and won't leak!
It's not shrinking the o ring at all. You're just not stretching it making it longer.
ill be damned! I have run into this issue with other products before.
Your push forward as your pushing. You are causing it to stretch. There is nothing wrong with the part it the installer that is improperly inserting it. Common mistake of o-ring installs.
bake it at 350 for maybe 30 min if nothing happens raise temperature.
Maybe put it in the freezer for a few minutes then install?
99.9% of the comments did not even see the video lol.
@@Eduardo_Espinoza 100% agree
You stretched it putting it on
No, they all come like that intentionally.
Ya not uncommon , by the time it's tugged around the perimeter they tend to grow a little. You may have to retrace (compress) a little to get slack out.
Silly-cone is the only way to go.
A little Vaseline goes a long way.
They didn't send you the wrong anything you just have 0 mechanic knowledge and or experience lol gale banks is the GOAT of diesel pickup truck technology dont doubt him ever!!!
Let's call it experience with this sort of seal.
RTV! Done and done
I'd bet you bought that diff cover because you saw all 50 of his videos on it.
It's easy to carefully use an Xacto knife to cut the O-ring and glue the material in a butt joint with CA glue.
I see no (veg oil or Vaseline) lubricant, in the heavy diesel world oil style seals are used heavy and see guys stretch the gasket
